State of the School District: Mamaroneck, NY

Summary Perspective

The Mamaroneck Union Free School District presents a story of institutional sustainability rather than growth, turnaround, or fiscal crisis. It is a self-contained K-12 Union Free School District organized under Article 35 of the New York Education Law, serving 5,565 students across six schools in the 2023-24 school year. The district operates its own elementary, middle, and high school programs without tuition-out arrangements or feeder dependencies on neighboring districts. This structural completeness means that a family choosing an address within the district's boundaries can trace a child's entire K-12 path through the same school system without the uncertainty of inter-district transitions.

The district's fiscal mechanics are governed by New York State's property tax levy cap, which the Office of the State Comptroller reported remained at 2 percent for the 2026-27 fiscal year. The Board of Education serves as the district's taxing authority, adopting the school tax levy as part of the annual budget. The budget is subject to a public vote held on the third Tuesday in May, and a district seeking to exceed the levy cap must obtain a 60 percent supermajority of voters casting ballots. If voters reject the proposed budget twice, the district must adopt a contingency budget, which generally caps the tax levy at the prior year's level with zero percent growth. These mechanics constrain how the district can respond to cost pressures, but no fiscal stress designation, active fiscal crisis, or governance transition is described in the materials on file.

On academics, the most recent assessment data on file consists of Advanced Placement proficiency rates from the 2023-24 school year. These rates vary across subjects, from 59.6 percent in AP Calculus AB to 100.0 percent in AP Chemistry and AP Computer Science A. State assessment data in the broader computed series covers 2006 through 2017, with a gap during the pandemic years and no data points bridging 2017 to 2023-24. The most recent graduation data is from 2019-20, when the cohort size was 407 students, though the graduation rate itself is not reported in the computed data on file. The district's chronic absenteeism rate was 13 percent for the 2022-23 school year. For the 2025-26 school year, the district holds a "Local Support and Improvement" accountability designation, indicating it is not identified for intensive state intervention through Comprehensive Support and Improvement or other targeted designations.

The single most decision-relevant contextual fact is the district's feeder structure. Because Mamaroneck operates a single middle school, Hommocks School, and a single high school, Mamaroneck High School, elementary school zone assignment does not select among competing secondary schools. Every student in the district feeds into the same secondary schools regardless of which of the four elementary attendance zones they live in. This eliminates a layer of uncertainty that exists in districts with multiple secondary schools and competing feeder patterns, where an elementary boundary change could redirect a child to a different middle or high school.

This report describes what is true about the district as of the data on file. It does not rate, rank, or recommend the district, and it does not assess whether the district is a fit for any particular family. The evidence base carries significant gaps: free and reduced-price lunch counts and rates, individualized education program counts and rates, and English learner counts and rates are all reported as missing in the computed data. These absences limit the conclusions that can be drawn from the available academic and enrollment figures, and they mean that the assessment results cannot be contextualized against the economic circumstances or special needs of the student population.

Key takeaways for families

• The district operates a complete K-12 program across six schools, meaning no student is tuitioned out to another district for any grade level, and all students converge into a single middle school and single high school regardless of which elementary attendance zone they start in.

• Advanced Placement proficiency rates for 2023-24 vary substantially across subjects, from 59.6 percent in AP Calculus AB to 100.0 percent in AP Chemistry and AP Computer Science A, but the computed data provides participation counts for none of these exams, making it impossible to distinguish broad-participation results from small-cohort results.

• The most recent graduation data on file is from 2019-20, when the cohort size was 407 students, but the graduation rate itself is not available in the computed data. This data reflects a cohort that was in its final year during the initial pandemic disruption and should not be assumed to represent current outcomes.

• The district's chronic absenteeism rate was 13 percent for the 2022-23 school year, meaning approximately 13 percent of students missed 10 percent or more of enrolled school days, whether excused or unexcused.

• For the 2025-26 school year, the district holds a "Local Support and Improvement" accountability designation, which means it is not identified for Comprehensive Support and Improvement, Additional Targeted Support and Improvement, or Targeted Support and Improvement.

• Elementary school assignment is determined by geographic attendance zone, with four zones corresponding to the four elementary schools. The only districtwide alternative is the Dos Caminos dual language program, which admits students at kindergarten entry through an application, screening, and lottery process.

• No active boundary study, redistricting process, rezoning proposal, school closure, or consolidation process was identified in district documents as of July 2026. The most recent capacity and utilization study on file is a Long Range Planning Study presented to the Board of Education in 2017.

• Free and reduced-price lunch counts and rates, individualized education program counts and rates, and English learner counts and rates are all reported as missing in the computed data, limiting the conclusions that can be drawn from the available academic and enrollment figures.

• New York State's property tax levy cap limits annual levy growth to the lesser of 2 percent or the rate of inflation, and the cap remained at 2 percent for the 2026-27 fiscal year. Exceeding the cap requires a 60 percent supermajority of voters on the budget proposition.

• The district's annual budget is subject to a public vote held on the third Tuesday in May. If voters reject the proposed budget twice, the district must adopt a contingency budget, which generally caps the tax levy at the prior year's level with zero percent growth.

• The Board of Education consists of seven members elected at large to three-year terms, with the next scheduled board election on May 18, 2027. The board does not use a ward or geographic district system for its members.

• The Village of Mamaroneck straddles two towns, and residents of the village may find themselves in either the Mamaroneck UFSD or the Rye Neck UFSD depending on which side of the town boundary their property occupies. A municipal boundary change does not automatically alter the school district boundary.

At a glance

The following table consolidates current-state signals available in the computed data and body sections. Where a data point is not available, the table states "Not available" rather than estimating or omitting the row. Numeric figures come exclusively from computed data sources, including the NCES Common Core of Data, the US Census Bureau Annual Survey of School System Finances (F-33) for FY2023, EDFacts, and NY State assessment data. The fiscal year for finance data is 2023. The graduation data is from 2019-20 and is labeled with that year. The accountability designation is for 2025-26. Several rows reflect honest nulls: the graduation rate itself is not in the computed data, only the cohort size. The state average for per-pupil spending is not available in the data on file. No housing market data is included because none was identified in the research.

How to read New York accountability

New York State's accountability system, established under the federal Every Student Succeeds Act (ESSA), classifies schools and districts into tiers based on multiple indicators. The state's ESSA accountability system incorporates academic achievement, student growth, English language proficiency, chronic absenteeism, graduation rate, and college, career, and civic readiness. The designations form a hierarchy of intervention intensity. Comprehensive Support and Improvement (CSI) is the most intensive category, applied to schools with the lowest performance or graduation rates. Targeted Support and Improvement (TSI) and Additional Targeted Support and Improvement (ATSI) apply to schools where specific student subgroups are consistently underperforming. Local Support and Improvement (LSI) is the designation for schools and districts that are not identified for these more intensive categories. According to the state's accountability status report guide, LSI schools receive support from the district and use continuous improvement planning materials, but they are not subject to state-led intervention.

The state's growth measure is an elementary- and middle-level accountability indicator that tracks how much students progress relative to academic expectations, separate from their absolute proficiency level. NYSED includes Student Growth as one component of the accountability framework, but no districtwide growth score is published by the Mamaroneck district. The absence of a published growth score means that one component of the state's accountability framework is not available for public review at the district level.

New York's property tax levy cap, described in the New York State Library's property tax cap toolkit, limits annual levy growth to the lesser of 2 percent or the rate of inflation, subject to adjustments for certain capital and pension costs. The Office of the State Comptroller reported that the cap remained at 2 percent for the 2026-27 fiscal year. A district seeking to exceed the cap must obtain a supermajority of 60 percent of voters casting ballots on the budget proposition, rather than the simple majority normally required. If voters reject the budget twice, the district must adopt a contingency budget, which generally caps the levy at the prior year's level.

No charter schools are identified in the district materials on file. School choice within the Mamaroneck district is limited to the Dos Caminos dual language program, which uses a lottery for admissions when applications exceed available seats at kindergarten entry.

For the Mamaroneck Union Free School District specifically, the 2025-26 accountability designation of Local Support and Improvement means the district is not identified for state-led comprehensive support or targeted intervention. The district's chronic absenteeism rate of 13 percent for 2022-23 is one of the indicators factored into the state's accountability determination. The district's annual budget vote, held on the third Tuesday in May, is the mechanism by which voters can approve or reject the spending plan that operates within the levy cap constraints, and a 60 percent supermajority would be required if the board sought to exceed the cap.

What kind of district this is: governance and geography

The Mamaroneck Union Free School District is an independent Union Free School District (UFSD) organized under Article 35 of the New York Education Law. The UFSD is a specific category of New York school district that, as a general reference on Union Free School Districts explains, operates as a self-contained educational entity with its own board of education and taxing authority. The legal framework for UFSDs is established in N.Y. Education Law 1950, which governs their formation, powers, and structure. In Mamaroneck's case, the district runs its own elementary schools, its middle school (Hommocks School), and its high school (Mamaroneck High School), covering grades K through 12. The district does not pay tuition to send its students to another district for any grade level, nor does it serve as a receiving district for tuition-in students from a feeder system. According to data from the National Center for Education Statistics Common Core of Data, the district enrolled 5,565 students in the 2023-24 school year across six schools, all of which are currently open: Central School, Chatsworth Avenue School, Hommocks School, Mamaroneck Avenue School, Mamaroneck High School, and Murray Avenue School. The district's headquarters are in Mamaroneck, New York, in Westchester County, and its official website provides district information.

Taxing authority and collection

The Board of Education of the Mamaroneck UFSD serves as the district's taxing authority. The board adopts the school tax levy as a component of the annual budget adopted each spring. However, the district itself does not collect taxes directly. Collection is handled by municipal governments based on the location of the property. For properties situated in the Town of Mamaroneck, the Town of Mamaroneck serves as the tax collector. For properties in the Village of Larchmont, which lies within the Town of Rye, the Town of Rye handles collection. This division of collection responsibilities operates under N.Y. Real Property Tax Law 1306 and related provisions of the New York Education Law governing school tax warrants. The practical consequence is that a property owner's school tax bill arrives from the town in which the property is located, even though the school district sets the levy amount.

New York State also imposes a property tax levy cap on school districts. For the 2026-27 fiscal year, the Office of the State Comptroller reported that the school district tax cap levy remained at 2 percent. This cap constrains the amount by which the district can increase its tax levy year over year, though certain exemptions exist for specific capital and pension costs. The New York State Library's property tax cap toolkit describes the cap as limiting levy growth to the lesser of 2 percent or the rate of inflation, subject to adjustments. A district seeking to exceed the cap must obtain a supermajority of 60 percent of voters casting ballots on the budget proposition, rather than the simple majority normally required.

Budget approval and the contingency mechanism

Under New York's Education Law, the district's annual budget is subject to a public vote by district residents. The vote is held on the third Tuesday in May. The New York State School Boards Association describes this process as a statewide requirement for school districts. A district social media post confirmed that the 2026 budget vote was held on May 19, 2026, with polling at local elementary schools from 7 a.m. to 9 p.m. The district's budget page publishes proposed budget documents for public review.

If voters reject the proposed budget, the Board of Education has the option to resubmit a revised budget for a second vote. If the revised budget is also defeated, the district must adopt a contingency budget. A contingency budget, as outlined in guidance on New York contingency budgets, imposes specific fiscal constraints. The tax levy under a contingency budget is generally capped at the prior year's levy, resulting in a zero percent increase. The contingency framework also bars certain expenditures, including new equipment purchases and capital expenditures related to community use of school facilities. The purpose is to ensure that essential educational operations continue while restricting discretionary spending growth. A 2020 analysis of New York's school budget process noted the pressure this creates for districts, as a single failed vote can move a district toward contingency status.

Board of Education composition and elections

The Mamaroneck UFSD Board of Education consists of seven members, each elected to a three-year term. Elections are conducted at large, meaning all district voters vote for all board seats regardless of where in the district they reside. The board does not use a ward or geographic district system for its members. According to Ballotpedia, the next scheduled board election is May 18, 2027. The district's Board of Education page provides additional information about board operations and meeting schedules, and the BoardDocs portal hosts meeting agendas and materials.

The district does not operate under mayoral control or any nonstandard governance arrangement. The Board of Education is the sole governing body, with authority over policy, budget adoption, and the tax levy.

Municipalities served and shared boundaries

The district's geographic footprint overlays several municipalities in Westchester County. The district serves the entirety of the Town of Mamaroneck and the entirety of the Village of Larchmont. It also serves the portion of the Village of Mamaroneck that falls within the Town of Mamaroneck. However, the Village of Mamaroneck straddles two towns, and the portion of the village that lies within the Town of Rye is also served by the Rye Neck Union Free School District. This means that residents of the Village of Mamaroneck may find themselves in either the Mamaroneck UFSD or the Rye Neck UFSD depending on which side of the town boundary their property occupies. A municipal boundary change, such as a village annexation or deannexation, does not by itself alter the school district boundary. The school district boundary must be changed separately through the statutory procedures described below.

Feeder structure

The district is not part of a feeder system. It operates a complete K-12 program, meaning students progress from elementary school through middle school to high school entirely within the district. There is no tuition-out arrangement for secondary grades, and no other district sends students to Mamaroneck on a tuition basis. This self-contained structure is characteristic of New York's Union Free School Districts, which were historically formed to provide education beyond the elementary level within a single district rather than relying on a separate high school district or a tuition agreement with a neighboring district.

Boundary change mechanisms

Two principal statutory routes exist to alter the boundaries of the Mamaroneck UFSD. The first, under N.Y. Education Law 2117, allows the Board of Education to alter district boundaries by resolution, provided that the alteration is approved by a majority of voters in the affected area and does not result in the creation of a new school district. This is a locally initiated process that requires both board action and voter ratification. The board proposes the change, but the voters in the affected area must approve it before it takes effect.

The second route, under N.Y. Education Law 170, allows the Commissioner of Education to change the boundaries of any school district upon the petition of twenty-five or more residents of the district or districts involved. The Commissioner must conduct a hearing before ordering any boundary change. This is a state-level process initiated by residents rather than by the board itself, and the decision rests with the Commissioner rather than with local voters.

In both cases, the key principle is that school district boundaries in New York are legally distinct from municipal boundaries. A change in a town or village line does not automatically move a school district line. The school district boundary can only be altered through one of these specific statutory procedures, ensuring that any boundary change involves either local voter approval or state-level administrative review.

Academic outcomes: the evidence base

The academic evidence base for the Mamaroneck Union Free School District draws on several distinct data streams, each measuring something different. New York State assessments measure student performance against state learning standards at specific grade levels. Advanced Placement exams measure performance on college-level curricula produced by the College Board. The state's accountability system combines multiple indicators, including assessment results, student growth, chronic absenteeism, and graduation rates, into a designation that carries practical consequences for how a school is supervised. None of these instruments captures everything a district does, and each carries limitations that affect how its results should be read.

What state assessments measure

New York State administers standardized assessments in English Language Arts and Mathematics in grades 3 through 8, and in Science at designated grade levels. At the high school level, the state has historically used Regents examinations as end-of-course tests in subjects including English, algebra, geometry, biology, earth science, global history, and U.S. history. These assessments are designed to measure whether students have met state learning standards at specific points in their education. They are not designed to measure college readiness, creativity, critical thinking beyond the tested standards, or learning in subjects and grade levels not tested. A district's results on state assessments describe how its students performed on those specific tests, in those specific grades and subjects, in the years the tests were administered. They do not describe the overall quality of education in the district. The state's ESSA accountability system uses these results as one component among several.

The multi-year series

The computed assessment data for Mamaroneck contains 65 distinct data series, spanning multiple subjects, grade levels, and student groups. The earliest data points date to 2006, and the series extends through 2025. Data points are present for the years 2006 through 2017 in the state assessment portion of the series. The most recent data points are Advanced Placement proficiency rates from the 2023-24 school year. Between 2017 and 2023-24, there is a gap in the data record. The assessment data is sourced from NY State Education Department data via a processed profile corpus.

The pandemic testing gap

The absence of data points for 2020 reflects the cancellation of New York State assessments in spring 2020. The federal government waived assessment requirements that year in response to the COVID-19 pandemic, and the state did not administer its standard tests. Testing resumed in subsequent years under modified conditions, but the break in the time series means that any comparison of pre-pandemic results to post-pandemic results spans two different testing contexts. The intervening years provide no data points to trace a continuous path from 2017 to 2023-24. This gap affects trajectory analysis: it is not possible to identify exactly when or how quickly any changes occurred during the missing years.

Level: Advanced Placement results, 2023-24

The most recent assessment data on file consists of AP exam proficiency rates for the 2023-24 school year. AP exams are scored on a 5-point scale, and a score of 3 or higher is the threshold many colleges use for awarding course credit. The proficiency rate represents the percentage of students who achieved that threshold. The computed data shows the following results for all students:

• AP Biology at Grade 12 showed a proficiency rate of 89.4 percent.
• AP Calculus AB at Grade 12 showed a proficiency rate of 59.6 percent.
• AP Calculus BC at Grade 12 showed a proficiency rate of 74.4 percent.
• AP Chemistry at Grade 11 showed a proficiency rate of 100.0 percent.
• AP Chemistry at Grade 12 showed a proficiency rate of 100.0 percent.
• AP Computer Science A at Grade 11 showed a proficiency rate of 100.0 percent.
• AP Environmental Science at Grade 12 showed a proficiency rate of 75.7 percent.
• AP European History at Grade 12 showed a proficiency rate of 85.5 percent.

Several AP series report missing values for 2023-24: AP Biology at Grade 11, AP Chemistry at Grade 10, AP Chinese Language and Culture at Grade 11, and AP Computer Science A at Grade 12. Missing values in AP data typically indicate that no students in that grade took the exam, or that the number of test-takers was small enough that reporting was suppressed to protect student privacy.

The rates vary across subjects. AP Chemistry and AP Computer Science A show 100.0 percent proficiency, while AP Calculus AB shows 59.6 percent. These are different exams taken by different groups of students, and the rates reflect the performance of those who chose to enroll in each course and sit for the exam. The computed data provides proficiency rates but not participation counts, so it is not possible to determine how many students took each exam or what share of the total student body participated. A high proficiency rate in a subject with few test-takers represents a different situation than the same rate in a subject with broad participation, and the data on file does not distinguish between these cases.

Trajectory: what the time series shows

The district's own trend commentary states that "Performance on Advanced Placement Exams has remained consistently high." This is a self-reported characterization. The computed data on file provides AP proficiency rates for 2023-24 but does not include a multi-year AP time series that would allow independent verification of this trend. The 65 series in the computed data include state assessment measures covering 2006 through 2017, but the AP data points visible in the provided series are limited to the single 2023-24 school year. Without comparable AP data from prior years, it is not possible to confirm or refute the district's claim of consistent performance using the computed data alone.

For the state assessment series covering 2006 through 2017, the data would in principle support trajectory analysis within that period. However, the specific series provided in the computed data for this report are AP proficiency rates, not the earlier state assessment series. The 65-series count indicates that additional data exists in the corpus, but the visible series are limited to the AP measures shown above.

Subgroup results

The computed AP proficiency data is reported for the "all students" group only. No subgroup breakdowns are available in the AP series on file. This means it is not possible from the computed data to examine whether proficiency rates vary across student groups defined by race, ethnicity, economic status, disability status, or English learner status. The absence of subgroup data limits the conclusions that can be drawn from the overall proficiency rates, because a single aggregate number can obscure variation among the students who make up that aggregate.

Graduation rate

The most recent graduation data on file is from the 2019-20 school year. The cohort size for that year was 407 students, sourced from EDFacts ACGR (Adjusted Cohort Graduation Rate) via the Urban Institute Education Data API. The graduation rate itself is not reported in the computed data on file; only the cohort size is available. This data is several years old and reflects a cohort that was in its final year of high school during the first spring of the pandemic disruption, when schools across New York shifted to remote instruction. It should not be assumed to represent current outcomes. The 2019-20 school year is the most recent graduation data available on file.

Chronic absenteeism

Chronic absenteeism data is available for the 2022-23 school year. The district's chronic absenteeism rate was 13 percent for all students, sourced from EDFacts Data Group 814. New York State defines chronic absenteeism as missing 10 percent or more of enrolled school days, whether the absences are excused or unexcused. This metric serves as one of the indicators in the state's accountability system under its ESSA plan. A rate of 13 percent means that approximately 13 percent of students in the district missed 10 percent or more of school days during the 2022-23 school year.

Accountability designation

For the 2025-26 school year, the district's accountability status is designated as "Local Support and Improvement" (LSI). According to the New York State Education Department's accountability status report guide, LSI applies when a school or district is not identified for state- or district-led comprehensive support. Schools in this category receive support from the district and use continuous improvement planning materials. The LSI designation indicates that the district is not identified for more intensive intervention through Comprehensive Support and Improvement (CSI), Additional Targeted Support and Improvement (ATSI), or Targeted Support and Improvement (TSI). The state's release of 2025-26 accountability determinations provides the framework for these categories.

The state's accountability system incorporates multiple indicators, including academic achievement, student growth, English language proficiency, chronic absenteeism, graduation rate, and college, career, and civic readiness. NYSED includes Student Growth as an elementary and middle-level accountability indicator, but no districtwide growth score is published by the district. The absence of a published growth score means that one component of the state's accountability framework is not available for public review at the district level.

What the evidence base does not include

Several categories of data that families might expect are not present in the computed data on file. Free and reduced-price lunch counts and rates are reported as missing. Individualized Education Program counts and rates are missing. English learner counts and rates are missing. These data points would normally provide context about the economic circumstances and special needs of the student population. Their absence means the assessment results cannot be contextualized against the district's student demographics in terms of poverty, disability, or language status.

The enrollment data that is available, sourced from NCES CCD via a processed profile corpus, shows a total enrollment of 5,565 students for the 2023-24 school year. Race and ethnicity data is reported, showing the following distribution: 3,596 white students (64.6 percent), 1,309 Hispanic students (23.5 percent), 187 Asian students (3.4 percent), 333 students of two or more races (6.0 percent), 125 Black students (2.2 percent), 6 American Indian or Alaska Native students (0.1 percent), and 3 Native Hawaiian or Pacific Islander students (0.1 percent). These figures describe who is enrolled in the district. They do not predict or explain academic outcomes, and they should not be interpreted as indicators of school quality or program effectiveness.

Reading the evidence

The academic evidence base for Mamaroneck consists of AP proficiency rates from 2023-24, a graduation cohort size from 2019-20, a chronic absenteeism rate from 2022-23, and an accountability designation from 2025-26. The AP rates show variation across subjects, from 59.6 percent in AP Calculus AB to 100.0 percent in AP Chemistry and AP Computer Science A. The state assessment data in the broader series covers 2006 through 2017, with a gap during the pandemic years. The graduation data is from 2019-20 and provides only cohort size, not a rate. The chronic absenteeism rate of 13 percent provides one measure of student engagement. The LSI accountability designation indicates the district is not identified for intensive state intervention. Each data point answers a specific and narrow question. None, alone or in combination, answers the broader question of whether the district is effective, because that question requires evidence and judgment beyond what any dataset provides.

Inside the district: variation between schools

The Mamaroneck Union Free School District operates six schools, all currently open. The configuration includes four elementary schools (Central School, Chatsworth Avenue School, Mamaroneck Avenue School, and Murray Avenue School), one middle school (Hommocks School), and one high school (Mamaroneck High School). This structure means that variation between schools is most relevant at the elementary level, where four separate buildings serve the district's youngest students. Once students reach Hommocks for middle school, they are in a single building regardless of which elementary school they attended, and they remain together through Mamaroneck High School. The convergence into shared secondary schools means that any differences in elementary school outcomes are not directly observable in the high school data, because all students are pooled by that point.

The academic assessment data available in the computed profile is reported at the district level rather than disaggregated by individual school. New York State assessment data for the 2023-24 school year includes Advanced Placement proficiency rates, but these are district-wide figures. Because the district has only one high school, the AP rates effectively reflect performance at Mamaroneck High School. However, for the elementary and middle school levels, the available data does not permit a school-by-school comparison of outcomes. A family looking to understand how Central School compares to Chatsworth Avenue School, or how Mamaroneck Avenue School compares to Murray Avenue School, will not find that level of disaggregation in the data available here.

What the district-level AP data does show is variation across academic subjects rather than across schools. For the 2023-24 school year, AP proficiency rates among twelfth graders ranged from 59.6 percent in AP Calculus AB to 100 percent in AP Chemistry. AP Biology showed an 89.4 percent proficiency rate among twelfth graders, AP Calculus BC showed 74.4 percent, AP Environmental Science showed 75.7 percent, and AP European History showed 85.5 percent. Among eleventh graders, AP Chemistry and AP Computer Science A both showed 100 percent proficiency rates. Some subject-grade combinations, including AP Biology for eleventh graders and AP Computer Science A for twelfth graders, are reported as missing, meaning no proficiency rate is available for those groupings. This subject-level variation tells a family something about the academic program at the high school, but it does not illuminate differences between the district's four elementary schools.

The district's enrollment data also presents limitations for understanding between-school variation. The total enrollment of 5,565 students in 2023-24 is reported as a district figure, with racial and ethnic composition broken out at the district level but not by individual school. The district reports 3,596 white students (64.6 percent of enrollment), 1,309 Hispanic students (23.5 percent), 187 Asian students (3.4 percent), 125 Black students (2.2 percent), 333 students of two or more races (6.0 percent), 6 American Indian or Alaska Native students (0.1 percent), and 3 Native Hawaiian or Pacific Islander students (0.05 percent). Without school-level enrollment breakdowns, it is not possible to describe how these figures distribute across the six buildings. A district average can conceal a wide spread, and in a district with four elementary schools, the composition of any single building could differ substantially from the district-wide figures. The data on file does not reveal whether that is the case here.

Additionally, several data points that could inform understanding of variation between schools are reported as missing. Free and reduced-price lunch counts and rates, individualized education program counts and rates, and English learner counts and rates are all listed as missing in the computed data. These metrics are often used to understand the composition of a school's student body and the resources directed toward specific populations. Their absence means this report cannot describe whether one elementary school serves a higher proportion of students eligible for free or reduced-price lunch than another, or whether the distribution of students with individualized education programs varies across buildings. The New York State Education Department's public reporting, accessible through the district's data profile, may contain school-level information that the computed profile used here does not capture, but this report cannot assert what that reporting shows without the underlying data on file.

The district does offer a dual language program with a separate application process, which introduces a form of programmatic variation that cuts across standard attendance boundaries. Families who apply to this program may have their children educated in a different instructional model than the standard English-language classroom, regardless of which elementary attendance zone they live in. The existence of this program means that even within a single elementary school, students may experience different instructional approaches. However, the data available does not indicate which schools host dual language classrooms or how outcomes for dual language participants compare to those in the standard program.

The district's self-reported outcomes, drawn from a 2017-2018 high school profile published by Mamaroneck High School, provide a snapshot of post-secondary results for the Class of 2017. The high school reported a 93 percent college enrollment rate, with 81 percent enrolling in four-year institutions. SAT scores were reported as 586 in evidence-based reading and writing and 581 in math, with a 44 percent participation rate. The ACT composite was reported as 28.2. These figures reflect the high school only and do not speak to variation at the elementary or middle school level. The 44 percent SAT participation rate also means that more than half of the graduating class did not take the SAT, according to the district's own figures, which limits the representativeness of those scores as a measure of the entire student body.

For families evaluating the district, the practical implication of this data landscape is that between-school variation within Mamaroneck cannot be assessed from the information on file here. The district's structure, with four elementary schools feeding into shared secondary schools, means that elementary school placement is the primary point at which building-level differences could matter to a family. But the available data does not describe what those differences are. Families seeking that level of detail would need to consult school-level report cards on the New York State Education Department website or contact the district directly for school-specific information that falls outside the scope of this report.

Advanced academics and pathway access

AP and IB offerings

Mamaroneck High School offers Advanced Placement courses according to its official course catalog for 2025-2026. No International Baccalaureate programme is listed for any school in the district. AP courses follow the College Board curriculum framework and culminate in standardized AP exams that can, depending on score and receiving institution policy, yield college credit or advanced placement at the postsecondary level.

The US Department of Education's Civil Rights Data Collection for SY2021-22 reports AP enrollment across the district's six schools. The totals, aggregated from six school-level rows, show 590 students enrolled in at least one AP course when counted by racial category: 477 White students (230 male, 247 female), 66 Hispanic students (33 male, 33 female), 23 Asian students (8 male, 15 female), 13 students of two or more races (4 male, 9 female), 9 Black students (5 male, 4 female), and 2 Native Hawaiian or Pacific Islander students (1 male, 1 female). No American Indian or Alaska Native students were reported in AP enrollment. The same collection reports 3 English Learner students enrolled in AP (3 male, 0 female), 29 students with IDEA disabilities (18 male, 11 female), and 93 students with Section 504 plans (46 male, 47 female). These disability and language categories overlap with racial categories and do not sum to a separate total.

Grade 8 Algebra I placement

Hommocks Middle School publishes Math Pathways materials, and the district's equity plan, finalized on February 4, 2021, references a Grade 8 accelerated Algebra Regents course. Public materials do not specify a test cutoff score, a GPA threshold, or a lottery mechanism for placement into this course. The absence of a published numeric benchmark means families cannot identify a single score or grade that determines entry. The district's own materials describe the pathway without enumerating the specific selection criteria, the body that makes placement decisions, or an appeals process for families who disagree with a placement outcome. The CRDC for SY2021-22 includes Algebra I enrollment data aggregated across six schools, but the computed data do not break out Grade 8 enrollment specifically from Algebra I taken in other grades or at the high school level.

Gifted identification

The CRDC for SY2021-22 includes a gifted and talented reporting category for the district's six schools. The computed data do not list any enrollment totals for gifted programs, which indicates that no students were reported under this category for that year or that no formal gifted program is operated. The district's equity plan and public course materials do not describe a separate gifted identification process, assessment instrument, referral timeline, or appeals procedure. Families seeking accelerated academic placement in Mamaroneck would therefore look to course-level acceleration, such as the Grade 8 Algebra pathway, rather than to a labeled gifted and talented program.

Selective program entry: Dos Caminos Dual Language

The Dos Caminos Dual Language Program operates with selective admissions. According to the district's application page, entry requires an application, student screening, and placement by lottery. This is the only program in the district for which public materials describe a formal selective admissions process with a lottery mechanism. A lottery means that when applications exceed available seats, a randomized selection process determines placement rather than a competitive academic threshold. The screening component precedes the lottery, which suggests that eligibility is established before randomization, but the district's public materials do not enumerate what the screening assesses, what criteria determine eligibility for the lottery pool, or how many seats are available in a given year.

The ceiling: dual enrollment and research programs

The uppermost academic pathway available to a Mamaroneck High School student includes both dual enrollment and original research programs. Select high school courses allow students to register for college credit through partner institutions while taking the course at MHS rather than on a college campus. Listed partners include Syracuse University through its Project Advance program, Iona College, SUNY Albany, Westchester Community College, and Siena College. Courses carry specific college-credit fees set by the partner institutions. One listed partner course notes a fee waiver for students eligible for free or reduced-price lunch, which reduces but does not necessarily eliminate the cost barrier for all such students. The available materials do not enumerate which specific MHS courses carry dual enrollment credit, how many college credits each yields, or whether credit transfer is guaranteed at any particular postsecondary institution.

Two research programs extend the ceiling further. Original Science Research (OSR) and Original Civic Research and Action (OCRA) are listed in the high school's course catalog. These programs allow students to conduct original research, though the specific structure, duration, prerequisites, and external partnerships are not enumerated in the available public materials beyond their listing as course offerings.

Equity plan and course-level access

The district's equity plan, finalized on February 4, 2021, references the Grade 8 accelerated Algebra Regents course within a broader set of equity goals. A data presentation dated November 2, 2021, was delivered to the Board of Education and addresses district performance metrics. Public materials do not describe a specific detracking proposal, a board vote to eliminate honors classes, or a formal policy change to merge tracked and untracked sections. The equity plan's reference to accelerated Algebra in Grade 8 indicates the district is examining access to advanced coursework, but the available documents do not enumerate a specific restructuring of existing course levels, a timeline for any such change, or organized positions for and against a particular proposal.

Enrollment, capacity, and boundaries: how stable is what you are buying

The Mamaroneck Union Free School District enrolled 5,565 students in the 2023-24 school year across six schools, according to NCES Common Core of Data. The district operates four elementary schools (Central, Chatsworth Avenue, Mamaroneck Avenue, and Murray Avenue), one middle school (Hommocks), and one high school (Mamaroneck High School). This structure shapes how predictable a family's school assignment is from the moment they choose an address, and several of its features reduce the kinds of uncertainty that exist in districts with more complex feeder systems.

How an address becomes a school seat

A resident address maps to one of four K-5 elementary attendance zones: Central, Chatsworth Avenue, Mamaroneck Avenue, or Murray Avenue. The district publishes an elementary school assignment zone map, though the map is undated, and the district advises confirming a specific address with the Family Information Center. This is a standard geographic assignment model: the street address determines the elementary school, and there is no general school-of-choice system at the elementary level beyond the dual-language option.

Families may alternatively apply at kindergarten to the districtwide Dos Caminos dual-language program. If applications exceed available seats, a lottery is conducted with applicants grouped by language dominance and home zone. The Dos Caminos application materials do not mention sibling or twin preference in the lottery. This program is the only districtwide alternative to zoned elementary assignment, and it is available only at kindergarten entry. The district also offers a Universal Pre-K program at Central Elementary School. If more applications are received than available seats, a mid-April lottery is used, and applications submitted after April 1, 2026 are placed on a waitlist. This is a capacity-managed program separate from the K-5 zoned enrollment system.

Feeder certainty: what elementary zone means for middle and high school

The district operates a single middle school (Hommocks) and a single high school (Mamaroneck High School). This means elementary zone assignment does not select among competing secondary schools. Every student in the district, regardless of which elementary school they attended, feeds into the same middle school and the same high school. For a buyer, this eliminates a layer of uncertainty present in districts with multiple secondary schools and competing feeder patterns: there is no risk that a boundary change at the elementary level would redirect a child to a different middle or high school, because there is only one of each.

Capacity and utilization

The most recent districtwide capacity and utilization study on file is a Long Range Planning Study presented to the Board of Education in 2017. No current districtwide utilization-percentage report was located in district materials from 2024 through 2026. This means there is no publicly available, up-to-date document that states, building by building, how close each school is to its rated capacity. A buyer seeking to understand whether capacity pressure exists at a specific elementary school would need to request current enrollment-versus-capacity data directly from the district, as it is not published in the materials on file.

The district's 2023-24 superintendent's recommended budget overview describes, in the district's own words, "stable K-12 enrollment with a gradual post-Covid recovery, and a slight decrease in K-5 total enrollment." This is a single point-in-time characterization from district budget materials, not a longitudinal series. A long-run enrollment trend line is not available in the data on file, so it is not possible to confirm from public documents whether the K-5 decrease has continued, reversed, or stabilized since that statement was made.

The district has pursued capital projects that bear on facilities condition and potentially capacity. A 2019 bond referendum addressed facilities needs across the district, as reported by lohud. More recently, a 2024 bond presentation and a capital bond summary sheet outline additional facilities investments. A construction project listing for Mamaroneck Avenue School's 2024 capital bond indicates building-level work at that school. New York State also requires periodic Building Condition Surveys, which assess the physical state of school buildings but do not constitute enrollment capacity analyses.

Active boundary or redistricting studies

No active boundary study, redistricting process, or rezoning proposal was identified in district documents as of July 2026. The research examined the district's 2026-27 budget hub, Board of Education minutes from November 2025, Board minutes from January 2024 and May 2024, capital and bond presentation materials, and facilities pages. Targeted searches for "boundary," "redistricting," "rezoning," "closure," and "consolidation" within district documents spanning 2016 through 2026 returned no active process. There is no live closure or consolidation process, no published criteria list for such actions, and no moratorium in effect. No district-published destination or outflow study was located either, meaning the district has not publicly analyzed where students go if they leave district schools or how many do so.

How boundaries could change, and what would signal it

In the absence of an active process, it is worth understanding the mechanism by which elementary attendance zones in a New York union free school district could change. Boundary adjustments are a board-level decision. The typical sequence begins with a demographic or capacity study, often conducted by an outside consulting firm, that projects enrollment by attendance area and compares it to building capacity. If imbalances are identified, the board may direct administration to develop options, which are then presented at public meetings. New York State does not impose a statutory redistricting process on individual districts, but state education law requires that any change in attendance zones be adopted by board resolution after public discussion. The district's 2017 Long Range Planning Study represents the most recent example of this kind of analysis on the public record.

Signals that a boundary review might be starting include the appearance of a new demographic or enrollment projection study on a Board of Education agenda, the hiring of a facilities or demographic consulting firm, public discussion of enrollment imbalances between elementary zones, or budget materials that reference capacity constraints at specific buildings. None of these signals is present in the current district materials on file.

Closure and consolidation exposure

No school closure or consolidation is under consideration. The district's six schools are all listed as open in NCES data, and no board minutes, budget documents, or facilities materials from 2024 through 2026 reference a closure or consolidation process. The district has not published criteria for evaluating school closures. In practice, closure decisions in New York districts are typically driven by sustained enrollment decline, severe building condition deficiencies, or fiscal pressure, and they require board action with public input. None of these conditions is documented in the available materials for Mamaroneck.

Grandfathering policy

No published grandfathering policy was identified. The district does not publish a general rule stating whether students currently enrolled in a school would be allowed to remain if their attendance zone were changed. In the absence of a stated policy, a family cannot assume grandfathering would apply in a hypothetical future redistricting. This is a common gap in district documentation and is not unique to Mamaroneck.

Transfer mechanics

The district does not publish a general intra-district transfer process for elementary school assignment beyond the Dos Caminos dual-language program. There is no stated open-enrollment window or application for requesting a different elementary school within the district. The district does not publish a transfer-transportation guarantee for families who might move within the district mid-year; families are advised to contact the Transportation Department for assistance.

For inter-district movement, registration is for residents only, and proof of residency is required. No general nonresident open-enrollment program is published. The district does note tuition income from billing nonresident students and billing other districts of residence in budget materials, which indicates some specialized out-of-district arrangements may occur through special education placements or district-to-district billing agreements. An out-of-district transportation application is available for families who need transportation to non-public schools, as required by New York State law.

Residency verification

The district requires proof of residency for enrollment. Families must provide at least one item from Section A and two items from Section B of the residency documentation requirements, as outlined on the registration process page. A change of address within the district requires submission of a Change of Address Questionnaire and updated documentation, per the change of address page. The district does not publish details of residency audit practices beyond these documentation requirements.

What the structure means for assignment predictability

The structural features of this district provide a degree of assignment predictability that follows directly from its configuration. The single middle school and single high school mean that secondary assignment is not contingent on elementary zoning. The four elementary zones are address-based and have been in place without published revision, though the undated zone map means a buyer should verify any specific address with the district. No active boundary, closure, or consolidation process exists as of the most recent board materials. The main gap in publicly available information is the absence of a current capacity utilization report; the most recent one dates to 2017. Without that document, a buyer cannot independently assess from public records whether any individual elementary building is approaching its enrollment ceiling.

Fiscal health and the tax picture

Per-pupil spending and revenue structure (FY2023)

According to the US Census Bureau Annual Survey of School System Finances (F-33) for FY2023, Mamaroneck Union Free School District had total revenue of approximately $159.8 million and total expenditures of approximately $173.0 million. Current spending, which excludes capital outlay and debt service, was approximately $140.6 million. Based on the F-33 membership count of 5,475 students, current spending per pupil was $25,673, of which $16,989 went to instruction. The revenue mix was 88.7% local, 8.7% state, and 2.6% federal. In dollar terms, local sources contributed approximately $141.8 million, state aid approximately $13.8 million, and federal aid approximately $4.1 million. This revenue structure means the district raises nearly nine of every ten revenue dollars from local property taxes, making it far less dependent on state aid than many New York districts outside the downstate suburban corridor. When state aid fluctuates, the impact on Mamaroneck's budget is proportionally smaller than in districts that rely on state funding for a larger share of revenue. Conversely, when local property values or assessment practices shift, the effect on the district's finances is amplified.

Adopted budget and structural balance

The district's adopted budget for 2026-27 totals $176,560,406, representing a 4.36% year-over-year increase. The district reports a per-pupil figure of $27,123.13 for this budget. The budget appropriates $0 of fund balance, meaning the district plans to cover all expenditures from current revenues rather than drawing down reserves. The audited FY2025 general fund showed no net change in fund balance after transfers, according to the district's own figures. No operating multi-year forecast was found in the reviewed budget documents. The budget book publishes bond-payment schedules through 2040-41 and energy performance contract schedules through 2042-43, but it does not publish projected operating surpluses or deficits for future years. The district does not explicitly label its financial position as "structurally balanced" in the materials reviewed, though the available documents are consistent with a balanced operating position: current revenues cover current expenditures without reliance on reserve drawdowns, and the adopted budget does not use fund balance to close a gap.

Federal pandemic relief and its expiration

The district's audited federal-award schedules show ESSER spending of $265,332 under CARES ESSER, $279,225 under ARP ESSER, and $6,467 under ARP Homeless II in 2023. No ESSER spending was identified in the 2024 or 2025 audits. The 2026-27 budget carries $250,000 of federal aid described as FEMA COVID reimbursement and Medicaid. The reviewed documents do not indicate that ESSER funds paid for recurring staff positions, nor do they identify positions that were cut, backfilled, or absorbed when the federal aid ended. The absence of ESSER spending in the two most recent audit years indicates the district had fully deployed its federal pandemic allocations by the end of 2023, and the 2024 and 2025 budgets were prepared without ESSER as a revenue source. Because the district's federal revenue share was only 2.6% of total revenue in FY2023, the loss of ESSER funds represented a small fraction of the overall budget, and the district's revenue structure did not require a structural adjustment to replace it.

Reserves and fund balance

The district's unassigned general-fund balance was $6,762,933 as of June 30, 2025, equal to 4.0% of the ensuing year's budget. According to the district's own figures, this amount sits at New York's 4% statutory ceiling for unassigned fund balance, which limits how much a district may hold in unrestricted reserves. The audited balance rose from $6,637,643 in 2023 to $7,687,619 in 2024, then declined to $6,762,933 in 2025. The decline from 2024 to 2025 brought the district back to the statutory maximum, which suggests the district drew on reserves during the year and then replenished to the ceiling level permitted by state law. A fund balance at the statutory ceiling leaves no room to accumulate additional unrestricted reserves without exceeding the cap, which means future budget gaps cannot be addressed by building up reserves beyond the current level unless the law changes.

Long-term obligations: debt, pensions, and OPEB

As of June 30, 2025, the district had $59,355,000 in outstanding debt. FY2025 debt-service expenditures were $6,514,896 against $161,454,552 in total expenditures and other financing uses, implying that approximately 4.04% of the budget went to debt service. The district also reported net pension liabilities of $6,187,873 for the Employees' Retirement System and $4,021,077 for the Teachers' Retirement System as of June 30, 2025. The total Other Post-Employment Benefits (OPEB) liability was $238,302,571. This OPEB figure represents the present value of promised retiree health benefits that have not been pre-funded. Unlike pension liabilities, which are partially funded through dedicated trust assets, OPEB liabilities in New York school districts are often unfunded, meaning the full amount represents a future claim on district resources. The $238.3 million OPEB liability is roughly 1.35 times the district's annual current spending, a ratio that contextualizes the scale of the obligation relative to the operating budget.

Credit rating

Moody's assigned an Aa1 rating to the district, with the last rating action dated March 26, 2021, classified as a new rating. The Aa1 tier is the second-highest level on Moody's rating scale. No subsequent rating actions were identified in the reviewed materials. A credit rating affects the interest rate the district pays when it borrows money through bond issuance; a higher rating typically results in lower borrowing costs, which reduces the debt-service burden on the operating budget.

Tax levy limit and the override mechanism

New York's tax levy limit law, commonly called the "tax cap," restricts the year-over-year growth in a district's tax levy to the lesser of 2% or the rate of inflation, with adjustments for growth in the tax base and certain other factors. A district that stays within this calculated limit needs only a simple majority, meaning 50% plus one vote, to approve its annual budget. A district that exceeds the limit must obtain 60% voter approval. This 60% threshold is the override mechanism.

For 2026-27, the district adopted a levy of $153,122,478, which was $2 below the calculated tax-levy limit of $153,122,480. According to the district's budget documents, because the levy remained within the cap, the budget required only a simple majority. Voters approved it by a vote of 850 to 164.

The district has twice exceeded the cap in recent years. In 2021-22, voters approved a budget with a 1.99% levy increase against a 1.20% permissible increase, with 77% voting yes. In 2025-26, voters approved a budget with a 4.98% levy increase against a 2.99% permissible increase, by a vote of 1,008 to 310, or approximately 76% yes. In both cases, the override margins exceeded the 60% threshold required by state law.

How a household tax bill connects to the district levy

The connection between an individual property tax bill and the district levy operates through a multi-step mechanism. First, the school board adopts a budget and determines the tax levy, which is the total dollar amount to be raised from property taxes after accounting for all other revenue sources such as state aid, federal aid, and fund balance. Second, the levy is distributed across all taxable properties within the district boundaries based on each property's assessed value. Third, the tax rate is calculated by dividing the total levy by the total taxable assessed value of all properties in the district, expressed as dollars per $1,000 of assessed value. Fourth, an individual household's school tax bill equals the tax rate multiplied by the property's taxable assessed value, divided by 1,000.

For 2025-26, the district's tax rate is $12.451323 per $1,000 of taxable assessed value, according to the Town of Mamaroneck tax rate schedule. A property with a taxable assessed value of $100,000 would generate a school tax bill of approximately $1,245. The assessed value of any given property is determined by the local assessor, not by the school district. The school district controls the total levy, subject to the tax cap and voter approval, but does not control how that levy is apportioned among individual properties. When a property's assessment changes, the owner's tax bill changes even if the district's levy remains constant.

Over the five-year period from 2022-23 to 2025-26, the district's published tax rate declined from $13.79 to $12.45 per $1,000 of taxable assessed value, with $12.41 projected for 2026-27. Over the same period, the levy rose from $134,454,645 to $153,122,478. Annual levy changes were 2.39%, 2.60%, 2.58%, 4.98%, and 3.07%, respectively. The declining tax rate alongside a rising levy indicates that the total taxable assessed value in the district grew faster than the levy, spreading the tax burden across a larger base and reducing the rate per $1,000 even as the total amount collected increased.

For comparison, the 2025-26 tax rate for the Scarsdale UFSD segment within the Town of Mamaroneck is $13.576578 per $1,000 of taxable assessed value, according to the same Town of Mamaroneck schedule.

Tax base composition

The district's tax base includes several large commercial and multi-family properties. According to a 2021 official statement for bond issuance, Consolidated Edison had the largest assessed valuation at $141,731,288, representing 1.51% of the district's 2020-21 assessed valuation. Other top taxpayers included Avalon Properties Inc. at $45,640,000 (0.49%), Larchmont Acres East Associates LLC at $28,500,000 (0.30%), and Palmer Terrace CO-OP at $27,617,983 (0.30%). No single taxpayer exceeded 2% of the total assessed valuation, indicating a tax base without extreme concentration in any one property owner. A diversified tax base means that the financial difficulty of any single large property owner would have a limited effect on the district's overall levy collection.

Capital spending and upcoming measures

A November 2025 district release described a proposed $54 million capital package. The district said $19 million of Building Condition Survey work had previously been deferred, covering site improvements, building envelopes, interior work, mechanical, electrical, and plumbing systems, security, ADA compliance, and classroom projects. This capital package would represent a future borrowing measure requiring voter approval if brought to referendum.

The district's recent capital history includes a $9.3 million bond passed in 2016 and a $49,266,170 bond passed in 2019, approved by a vote of 856 to 219. In 2025, voters approved the establishment of a $20,000,000 capital reserve fund. In 2026, voters authorized a $9,000,000 capital reserve expenditure. Capital reserves allow the district to set aside funds for future projects without immediately issuing bonds, but the $54 million proposed package exceeds what the existing reserves can cover, which means additional borrowing would likely be required.

Annual budget vote history

The district's annual budgets have consistently passed voter approval. According to Westchester Putnam School Boards Association records, the 2022-23 budget passed with 87% support, the 2023-24 budget with 83%, and the 2024-25 budget with 87%. The 2025-26 budget, which required an override of the tax levy limit, passed 1,008 to 310, or approximately 76% yes. The 2026-27 budget passed 850 to 164. All annual budget measures and capital propositions on the ballot in these years were approved by voters.

The municipal and land-use context

No active boundary changes, mergers, or consolidations

A review of Mamaroneck Union Free School District Board of Education meeting recaps covering 2024 through 2026 identified no boundary changes, annexations, mergers, or consolidations affecting the district. The Town of Mamaroneck's comprehensive plan repository and the Village of Mamaroneck's planning document repository were likewise checked for restructuring filings, and none were found. As of July 2026, no pending reorganization of the district's structure, attendance zones, or municipal boundaries appears in the official records reviewed.

This absence is significant because New York State provides specific legal mechanisms for school district reorganization, including consolidation, annexation, and dissolution, as outlined in a School District Reorganization primer published by the New York State Education Department in July 2024. Any such action would require petition, voter referendum, and State Education Department approval. None of these steps has been initiated for Mamaroneck UFSD in the period examined.

The 2009 Westchester County housing consent decree: closed and without direct district mandate

Westchester County entered a federal fair-and-affordable-housing consent decree in 2009. The matter is historical and closed. Westchester County announced on August 4, 2021 that the federal court had accepted the county's substantial compliance, closed the case, and ended the federal monitor's role. No active decree affecting this district was found in the trailing 24-month review period.

The county's announcement states that the settlement was terminated. A separate Westchester County Legislature news item notes that Westchester taxpayers saved $3 million by not including Mamaroneck housing units in the settlement, indicating that Mamaroneck-specific units were excluded from the decree's obligations. No order against Mamaroneck Union Free School District, or stated effect on its enrollment, tax base, or budget, was identified in the official records closing the case.

A February 2024 report on affordable housing in Mamaroneck published by the Village of Mamaroneck provides background on local affordable-housing efforts, but the document does not identify any active mandate imposed on the school district as a consequence of the county-level decree. The decree operated at the county level, and its closure in 2021 removed the federal monitor entirely. The district itself was not a party to the consent decree, and no continuing obligation on the district was identified in the records reviewed.

Budget approval mechanism: voters, not a municipal funding body

Mamaroneck UFSD operates as a union free school district, which means its annual budget is presented directly to qualified district voters for approval rather than appropriated by a municipality. This structural fact shapes how fiscal decisions flow into the district.

The Board of Education presents the district budget to qualified district voters. The district's official budget press release states that voters approved the 2026-2027 budget on May 19, 2026. New York Education Law Section 1716 governs estimated expenses for districts whose budgets are subject to voter approval, establishing the legal framework for how the district's spending plan is formulated, presented, and ratified.

Because the district's operating budget does not pass through a municipal appropriation, no direct municipal-funding transmission mechanism applies. The fiscal health of the Town of Mamaroneck or the Village of Mamaroneck does not directly determine the district's annual spending authority in the way it would for a city school district dependent on a municipal council for budget passage. Instead, the district's fiscal relationship is with its own voters, who approve or reject the budget at the ballot box. No municipal-funding dispute was found in the district's 2024 through 2026 Board of Education meeting recaps.

What municipal changes would affect this district

Although no active structural changes were identified, several categories of municipal or land-use action could, if initiated, affect Mamaroneck UFSD. Understanding these mechanisms clarifies why the current absence of activity matters.

First, a municipal annexation or boundary adjustment involving the Town or Village of Mamaroneck could alter the geographic area from which the district draws students and tax revenue. School district boundaries in New York are not always coterminous with municipal boundaries, so a change in municipal lines would not automatically change district lines. However, a municipal reorganization could trigger a review of school district boundaries if the affected territory falls within the district's attendance area. Such a change would require action under the reorganization procedures described in the NYSED reorganization primer, including petition and referendum.

Second, large-scale residential development within the district's boundaries could affect enrollment without changing district structure. New housing construction approved by the Town of Mamaroneck or the Village of Mamaroneck through their respective planning processes could introduce additional students into the district's schools. The district's budget, approved by voters, would need to accommodate any enrollment growth through increased instructional spending, capital projects, or both. The Town of Mamaroneck comprehensive plan and the Village of Mamaroneck planning documents serve as the repositories where such development proposals would appear. No such proposals with direct district-level fiscal impact were identified in the records reviewed for this period.

Third, changes to the district's own organizational structure, such as a consolidation with an adjacent district or a dissolution, would require a multi-step legal process under New York State Education Law. This process begins with a petition, proceeds to a voter referendum in each affected district, and requires final approval from the New York State Education Department. The district's official website and budget page do not indicate that any such process has been initiated.

In summary, Mamaroneck UFSD faces no active municipal restructuring, no continuing housing mandate from the closed county-level consent decree, and no municipal-funding-body dispute. The district's fiscal relationship runs directly to its voters under New York Education Law Section 1716, and the municipal and land-use context is, as of the most recent records reviewed, stable.

Real estate and the price of admission

The computed home value index for the Mamaroneck Union Free School District is $1,395,742 as of April 30, 2026. This figure is a ZIP-level approximation derived from Zillow's Zillow Home Value Index (ZHVI) across four ZIP codes (10538, 10543, 10583, and 10801), allocation-weighted to the district through the NCES-ZCTA relationship file. ZIP boundaries do not align with district boundaries, so the index reflects the broader market in which the district operates rather than a parcel-level measure. The corresponding rent index is $6,969 as of April 30, 2026, also a ZIP-level approximation from Zillow's ZORI data across the same four ZIP codes. Zillow's ZHVI estimates typical home values for the middle tier of the market in a given area, while ZORI estimates observed rents on listed units. Both are aggregate measures and do not reflect any individual property's value or rent.

At the Village level, official housing materials identify rent-stabilized units and note limited turnover. A district-wide rental-vacancy rate was not published in the retrieved records.

Residential development pipeline

Three residential projects were under review in the Village of Mamaroneck as of the retrieved records:

• 338-352 Mount Pleasant Avenue: A proposed 63-unit all-affordable multifamily project. Local reporting identified 54 studios and six one-bedroom units; the remaining bedroom mix was not established in retrieved records. The project appeared on Board of Trustees agendas and abstracts.
• 254 Center Avenue: Four townhouses across two lots, with two dwellings each. The tenure and bedroom mix was not published in the retrieved agenda.
• 150 Madison Street: A proposed two-family dwelling replacing a single-family home. The tenure and bedroom mix was not published in the retrieved agenda.

None of these projects carried an enrollment or school-tax-base estimate in the retrieved documents. Residential development can affect school districts through two channels: added school-age children, which increases enrollment and per-pupil costs, and added taxable assessed value, which expands the tax base and can lower the tax rate needed to raise a given levy. Without enrollment projections or assessed-value estimates attached to these proposals, neither channel can be quantified from the available record.

Zoning changes

The Village of Mamaroneck enacted Local Law 3-2025, a downzoning measure affecting the Washingtonville neighborhood on parcels within the Mamaroneck UFSD school tax roll. The law limits an affected residential area to one- and two-family residences where one- through four-family residences had previously been allowed. The law's effective date depends on filing with the New York Secretary of State; the filing date was not established in the retrieved document. No enrollment or school-tax-base estimate was provided in the law itself. Downzoning restricts the density of future development, which can limit the addition of new housing units and, by extension, the growth of the taxable assessment base in the affected area. The Village's 2025 Laws page lists the enacted law.

Commercial tax base

Two commercial projects appeared in the Village of Mamaroneck Planning Board pipeline:

• 416 Waverly Avenue: A commercial/industrial storage and office expansion. A site-plan extension request appeared on the Planning Board's January 22, 2025 agenda.
• 1025 Rushmore Avenue: Recreation, maintenance, and clubhouse improvements. This project was under Planning Board site-plan and wetland review in May 2026.

On the risk side, the district's budget documents identify recurring tax certiorari exposure. Tax certiorari is the legal process by which property owners challenge their assessed valuations; successful challenges result in refunds drawn from the district's tax levy. The district reports material annual spending on certiorari refunds, with prior-year actuals in the hundreds of thousands of dollars. This exposure applies to the district-wide taxable assessment base and represents a structural uncertainty in revenue planning, as refunds for prior-year over-assessments are paid from current-year levies.

PILOT and revenue diversions

The Mamaroneck Towers project operates under a payment-in-lieu-of-taxes (PILOT) agreement. A PILOT is a mechanism in which a property owner makes negotiated payments to a municipality or district instead of paying standard property taxes; the payments may differ from what conventional taxation would generate. District-reported PILOT revenue from Mamaroneck Towers appears in the district's budget documents. These are receipts to the district and do not quantify taxes forgone under the agreement. The Westchester County IDA's project documents for Mamaroneck Towers are on file.

Infrastructure

A Town of Mamaroneck construction alert posted July 3, 2025 described curb, ADA-ramp, pavement-resurfacing, and pavement-marking work on the Murray Avenue corridor, with completion expected in August 2025. Murray Avenue School, located at 250 Murray Avenue, sits on the work corridor. The notice indicated that daytime work and corridor changes would affect school access and curbside operations. No enrollment effect was quantified in the notice, and no later completion confirmation was found in the retrieved records.

The choice ecosystem

New York has no enacted K-12 education savings account or voucher program, according to ECS and NCSL state policy scans. No Mamaroneck Union Free School District uptake or district fiscal effect is published, because no such program exists for families to access.

Charter schools in New York are authorized through either the New York State Board of Regents or the SUNY Board of Trustees, not through local school districts. No Mamaroneck or Larchmont charter school appears in the NYSED charter school directory, and the district publishes no charter-school posture or partnership. No charter-related disputes or applications are on record. Families living within district boundaries who wish to attend a charter school would need to look to schools authorized elsewhere in Westchester County or beyond, and transportation to nonpublic schools applies within a 15-mile radius under state law.

The district operates no formal magnet-school system. Its closest equivalent is Dos Caminos, a districtwide Spanish-English dual-language immersion program serving students in kindergarten through grade 12. Elementary instruction takes place at Mamaroneck Avenue School, and the program continues through the secondary grades districtwide. Families must complete standard district registration before applying to Dos Caminos. Applications follow a defined timeline, and waitlist procedures apply when demand exceeds available seats. The district describes this as a program rather than a school of choice, but it functions as the district's primary opt-in instructional option at the elementary level.

Several private schools operate in or near the district's attendance zone, and each publishes its own tuition schedule. The French-American School of New York lists 2026-27 tuition of $39,660 for nursery through kindergarten, $42,030 for grades 1 through 8, and $46,825 for grades 9 through 12. Westchester Day School serves students from age 2 through grade 8 and publishes a 2026-27 schedule spanning $12,250 to $33,725 depending on the early-childhood program and grade level. Resurrection School, serving PK3 through grade 8, lists 2026-27 tuition of $11,500 for PK3 half-day, $12,250 for PK3 and PK4 full-day and kindergarten, and $11,250 for grades 1 through 8 for the first child, with sibling discounts available. Rye Country Day School, serving pre-kindergarten through grade 12, publishes 2026-27 tuition of $53,210 for pre-kindergarten through grade 4, $55,540 for grades 5 through 8, and $59,070 for grades 9 through 12, with lunch included.

New York requires families providing home instruction to follow state regulations that include filing an annual notice of intent, submitting individualized home instruction plans, and providing quarterly assessments and annual evaluations. The district tracks homeschool participation as required by state law. No microschool or learning-pod-specific regulatory framework exists in New York, and the district does not publish a separate count of students enrolled in such arrangements.

Programs, logistics, and special populations

Special education

NYSED reports 783 students with disabilities in the Mamaroneck Union Free School District, representing 14% of 2024-25 enrollment. The district operates a continuum of placements aligned with the least-restrictive-environment requirement under federal and state law. That continuum includes resource room support, where students receive specialized instruction in a small-group setting for a portion of the day; integrated co-teaching, in which a general education teacher and a special education teacher share instruction in the same classroom; and special classes for students whose needs require a more structured, separate setting. Eligibility and placement are determined by the Committee on Special Education and reviewed at least annually.

The district also operates the Transition Academy at Mamaroneck High School, serving students with disabilities who have completed their high school academic requirements but continue to need support in developing post-secondary life, vocational, and community skills. The Hommocks Middle School special education department provides services at the middle level. Unified Theatre and unified athletics, which pair students with and without disabilities in shared performance and competitive settings, extend the inclusion model beyond the academic day.

English learners and dual language

NYSED reports 280 English-language learners in the district, representing 5% of 2024-25 enrollment. The district provides three instructional models for these students, spanning kindergarten through grade 12, as described on its multilingual programs page. Standalone English as a New Language (ENL) pulls students into dedicated language-development classes. Integrated ENL embeds language instruction into content-area classes co-taught by an ENL specialist and a content teacher. The third model, Dos Caminos, is a Spanish-English dual-language immersion program in which students receive instruction in both languages across content areas. Elementary instruction for Dos Caminos takes place at Mamaroneck Avenue School, and the program continues through the secondary grades districtwide. Families must complete district registration before applying to Dos Caminos, and seats are subject to timeline and waitlist procedures.

Pre-kindergarten

The district operates a Universal Pre-Kindergarten program using a lottery model. Approximately 72 seats are filled by lottery, and late applications are waitlisted after the deadline. The program runs five hours per day for 180 days at Central Elementary School. The Healthy Kids program operates on site for wraparound care. Families are responsible for providing transportation to and from UPK, as the district's busing eligibility thresholds do not cover pre-kindergarten students.

Career and technical pathways

Mamaroneck High School offers several elective sequences that align with career and technical fields, though none are labeled as NYSED-approved CTE programs. Through the STEAM Studio and CoLAB, students can pursue pathways in architecture and built-environment design, computer science, and engineering and mechatronics. A Culinary Arts sequence spanning three courses covers food preparation and hospitality. A Design Studio sequence spanning three courses covers graphic, product, and environmental design. These pathways operate within the high school's regular departmental structure rather than as separate career academies or state-approved technical programs. The distinction matters for families comparing options: NYSED-approved CTE programs carry specific state endorsements and may confer additional graduation pathways, while these electives do not carry that designation.

Athletics and arts

The district's athletics program includes sports that are uncommon in many districts of similar size: fencing, skiing, girls flag football, boys and girls ice hockey, and coed bowling. Unified basketball and unified bowling, which include students with and without disabilities on the same teams, are offered alongside Special Olympics participation. On the arts side, the PACE program is a four-year Performing Arts Curriculum Experience spanning dance, music, and theatre at Mamaroneck High School. Additional offerings include Unified Theatre, the Kinesthesia dance showcase, the Soundscapes music showcase, and a one-act play festival.

Transportation

The district's transportation policy sets eligibility based on distance from home to school. Students in grades K through 8 who live more than 2 miles from their school are eligible for busing. Students in grades 9 through 12 who live more than 3 miles from school are eligible. Transportation to nonpublic schools is provided within a 15-mile radius of the student's home, as required by New York State law. These thresholds mean that some families living within the district's relatively compact geography will not qualify for bus service, particularly at the elementary level where neighborhood schools are closer to homes. Families who live within the mileage cutoffs must arrange their own transportation, which can affect morning and afternoon routines, especially in households where both parents work outside the home.

Bell times and daily schedule

School hours vary by building and day type. Elementary schools run from 8:40 a.m. to 3:00 p.m. Hommocks Middle School starts at 8:10 a.m. and dismisses at 2:46 p.m., with a W.I.N. (What I Need) period extending the day to 3:20 p.m. on Monday through Thursday. Mamaroneck High School begins at 8:00 a.m., but dismissal times vary by day type: 2:40 p.m., 3:00 p.m., 2:22 p.m., or 2:58 p.m. depending on the schedule rotation. Families with children in multiple buildings will need to coordinate around three different start times and multiple dismissal patterns. The high school's variable dismissal schedule means that pickup times, after-school activity planning, and transportation arrangements shift depending on the day of the week.

Class size planning targets

The district's board of education has established planning guidelines for class sizes, identified as planning targets rather than contractual caps. For the 2026-27 school year, these targets are: kindergarten at 22 students (19 at Mamaroneck Avenue School), grade 1 at 22 (21 at Mamaroneck Avenue School), grades 2 and 3 at 25, grades 4 and 5 at 26, and the Dos Caminos dual-language program at 24 for grades K through 5. The lower targets at Mamaroneck Avenue School reflect the presence of the dual-language program at that site. NYSED publishes 2024-25 class-size averages for this district, including K-2 and grades 3-8 ELA and math section sizes and selected high school subjects, on the district's NYSED profile. Planning targets and actual averages serve different purposes: targets guide staffing and sectioning decisions before the school year begins, while published averages reflect what materialized after enrollment settled.

Before and after school care

The Boys and Girls Club of New Rochelle operates after-school programming at multiple K-5 school sites within the district. BGCNR may use a waitlist if sites reach capacity, so early registration is relevant for families relying on this option. For UPK families, the Healthy Kids program offers both before- and after-care at Central Elementary School, where the district's pre-kindergarten program is housed. The district lists these providers among its community partners. UPK applications received after the lottery deadline are waitlisted, which can affect access to both the pre-K program and the wraparound care that depends on enrollment in it. The district does not publish specific costs for the BGCNR after-school program or the Healthy Kids wraparound care; families should contact those providers directly for current fee schedules.

Calendar

The 2026-27 calendar sets the first student day as Wednesday, September 2, 2026. The last day is Friday, June 25, 2027, with elementary early dismissal on that date. The district does not operate on a four-day-week schedule. The calendar follows a traditional academic year structure, and families should consult the district's published calendar for specific holiday recesses, conference days, and other closures that affect weekly routines throughout the year.

Safety, climate, and community

New York State requires school districts to report safety incidents through the School Safety and the Educational Climate (SSEC) system, administered by the New York State Education Department. The SSEC reporting cycle runs from July 1 through June 30 and includes summer school sessions. Its Summary Data Collection Form records incidents rather than unique students, meaning a single student involved in multiple incidents is counted each time. Each incident is counted once and assigned to the most serious applicable category. The reporting categories include violent incidents, weapons incidents, and discrimination, harassment, or bullying, with cyberbullying included under the latter. The most recent SSEC reporting cycle on file covers the 2024-25 school year, using the form designated for districts in the "Rest of State" category, which applies to all districts outside New York City. The SSEC reporting instructions and the 2024-25 reporting memo are published by NYSED. No SSEC incident counts specific to Mamaroneck UFSD are available in the materials reviewed for this report.

Federal disciplinary data comes from the U.S. Department of Education's Civil Rights Data Collection (CRDC) for the 2021-22 school year. The CRDC tracks disciplinary actions for students without disabilities separately from students with disabilities, using the designation "WODIS" (without disabilities) in its field labels. The three disciplinary categories are in-school suspensions, single out-of-school suspensions, and multiple out-of-school suspensions. Each category counts students who received at least one suspension of that type during the school year, not the total number of suspension incidents. A student who received both an in-school and an out-of-school suspension would appear in both categories. English Learner status is tracked as a separate demographic dimension that overlaps with race and ethnicity, so students counted in the English Learner categories are also counted in their respective race and ethnicity categories.

For the 2021-22 school year, the CRDC recorded 25 in-school suspensions of students without disabilities in Mamaroneck UFSD. Of these, 10 involved white male students, 6 involved Hispanic male students, 2 involved Hispanic female students, 2 involved Black male students, and 1 involved an Asian male student. Separately, 3 English Learner male students and 1 English Learner female student received in-school suspensions. The CRDC recorded 27 single out-of-school suspensions of students without disabilities. Of these, 7 involved Hispanic male students, 4 involved Hispanic female students, 4 involved white male students, 2 involved white female students, 2 involved Asian male students, 2 involved Black male students, and 2 involved Black female students. One female student of two or more races received a single out-of-school suspension. In the English Learner dimension, 2 male students and 1 female student received single out-of-school suspensions. The district recorded zero multiple out-of-school suspensions for students without disabilities in 2021-22. No female students received in-school suspensions in the white, Black, Asian, or two-or-more-races categories.

The district's Code of Conduct describes discipline as a teachable moment and calls for restorative practices with progressive, age-appropriate responses. The District-Wide Emergency Management Plan for 2025-2026 was posted with an update noted as November 2025. No explicit assignment of school resource officers is stated in the reviewed materials. School resource officers, where employed by districts, are typically sworn law enforcement personnel assigned to schools, but the district's emergency plan does not reference such positions.

Cell phone policy became a subject of public discussion during the 2024-25 school year. In fall 2024, the district implemented restrictions at Hommocks Middle School using all-day signal-blocking pouches, and at Mamaroneck High School requiring phones to be stored away during instructional periods using teacher-directed caddies. Student journalism at MHS Globe and community reporting in the Larchmont Loop documented disagreement among students, parents, and officials over these restrictions. Sources agreed on the core rules but no district statement resolving the debate was subsequently published.

New York State then imposed a separate statewide requirement for the 2025-26 school year. Under the distraction-free schools policy announced by Governor Hochul, districts must adopt policies prohibiting unsanctioned use of personal internet-enabled devices during the instructional day, with defined exceptions. No 2025-26 implementation document specific to Mamaroneck UFSD was located on the district's website or board portal in this audit. The last verifiable district-specific rules predate the state mandate and correspond to the fall 2024 restrictions described above.

The Board of Education reviewed a Belonging Survey during the 2025-26 cycle, described as measuring inclusion, connection, and school climate over time, according to board meeting recaps. No numerical results were published in the recap. A Daily Voice report indicated that nine in ten Mamaroneck High School students reported feeling safe, though the year and methodology of that survey are not specified in the available materials.

A personnel matter reached formal resolution during the period under review. A district employee sought permission to file a late notice of claim after a workplace incident, asserting the district's notice and support were insufficient. The district disputed timely knowledge connecting the incident to alleged negligence and the reasonableness of the delay. On May 21, 2025, the Appellate Division, Second Department reversed a 2023 lower-court order, denied leave to serve a late notice of claim, and dismissed the proceeding. The appellate court resolved the procedural dispute in the district's favor without adjudicating the underlying negligence allegation.

Leadership, governance, and labor

The Superintendent of Schools is Charles (Chuck) Sampson, Ed.D., who began his tenure on November 1, 2023. Prior to his appointment in Mamaroneck, Sampson served as superintendent of New Jersey's Freehold Regional High School District, according to local reporting. His appointment was also covered by Patch. The district's superintendent page lists his title and role. No public contract end date or other notable employment terms were located on district or board sites, which means the duration of Sampson's current commitment to the district is not publicly documented in the available record.

Sampson succeeded Robert Shaps, who retired effective October 31, 2023, after 13 years leading the district. Shaps's retirement was announced on the district's Facebook page and covered by the Mamaroneck High School student newspaper. The transition from Shaps to Sampson represents one superintendent change over the past decade. Shaps's departure was characterized as a retirement, and Sampson's start date of November 1, 2023, immediately followed Shaps's October 31, 2023, end date, leaving no identified gap requiring interim leadership. The single transition in 13 years means the district has experienced relative stability in its top administrative post compared with districts that cycle through superintendents every two to three years, though the current superintendent's contract terms are not publicly available to assess future continuity.

Board of Education

The Board of Education comprises seven members. The district's board page identifies the current membership as President Athena Maikish, Vice President Michael Davidson, Secretary Michele Metsch, and Trustees Sally Cantwell, David Carlos, Ariana Cohen, and Stacey D'Arcy. Board meeting recaps are published on the district website, and board policies are accessible through the district's policies page. The board's meeting schedule and portal are available through the district calendar and board platform.

Recent board elections have followed a pattern of annual May votes, with varying levels of competition. On May 17, 2022, two board seats with three-year terms were on the ballot. The May 16, 2023 election was uncontested, with David Mendes Carlos and Michele Metsch running for two available seats. On May 21, 2024, voters decided the school budget and board seats. The May 20, 2025 election was also uncontested, with two candidates running for two seats. Most recently, on May 19, 2026, voters decided the school budget and board seats, according to local reporting. Ballotpedia also tracks these elections. Turnout figures were not located in the available public sources for any of these elections. The frequency of uncontested races means that in multiple recent cycles, the number of candidates matched the number of open seats, and voters did not choose among competing candidates for those positions.

District cabinet

The district's administrative cabinet includes four assistant superintendents, as listed on the district directory. Sylvia Wallach serves as Assistant Superintendent for Business Operations. Jeffrey Moore, Ed.D., serves as Assistant Superintendent for Curriculum and Instruction. Claire L. Reinhard, Ed.D., serves as Assistant Superintendent for Administration and Personnel. Tamar Walker, Ed.D., serves as Assistant Superintendent for Student Support Services and Health Services.

Bargaining units and contracts

Four bargaining units represent district employees. The Mamaroneck Teachers' Association represents teachers and maintains a public website. The Association of School Administrators represents administrators. The CSEA-Teacher Aides Unit and CSEA, Local 1000 AFSCME, AFL-CIO represent non-teaching staff.

The latest publicly located Mamaroneck Teachers' Association agreement was a three-year deal approved in March 2023, covering the 2023-24 through 2025-26 school years, according to local reporting. No public successor agreement, declared impasse, or strike activity was located as of July 25, 2026. The district posts a teachers' salary schedule reflecting 2022-2023 figures, but no district-published comparison to neighboring districts was found. The Association of School Administrators contract is posted publicly and covers 2023 through 2026. A Teacher Aides contract and a non-teaching unit agreement are also available on district resources.

No published district policy or current collective bargaining agreement excerpt establishing a class size cap was located on public pages. No work stoppages, strikes, or labor disputes were identified in the available record.

State oversight and fiscal stress

No current state fiscal stress designation or state monitor has been identified for the district. The New York State Comptroller's fiscal stress monitoring system for schools and the State Education Department's monitor listing do not indicate active intervention. A state audit of the district has been published by the Office of the State Comptroller.

Litigation

One material litigation matter was located in the available public record. In Matter of Cooke v. Mamaroneck Union Free School District (Appellate Division, Second Department, D77157), petitioners commenced a late-notice-of-claim proceeding in March 2023. The Supreme Court, acting as the trial court, granted the petition on June 26, 2023. The Appellate Division reversed that decision on May 21, 2025, denying the petition and dismissing the proceeding, according to the court's published decision. The matter is closed, and the appellate ruling ended the late-notice proceeding against the district with no ongoing obligation. No other material litigation was identified in the available public sources.

Risks and watch items: the forward calendar

Contract expirations

The three-year Mamaroneck Teachers' Association agreement, approved in March 2023, covers the 2023-24 through 2025-26 school years. That contract period concluded on June 30, 2026. As of July 25, 2026, no public successor agreement, declared impasse, or strike activity had been located. The absence of a publicly posted successor agreement means the district's largest bargaining unit is operating beyond the term of its last documented contract. Negotiations may be underway without public disclosure, or the parties may have reached a successor agreement not yet posted publicly; the available record does not distinguish between these possibilities. The Mamaroneck Teachers' Association and the district website are the primary sources to monitor for updates. Board meeting recaps would be the venue for any public discussion of negotiation status.

The Association of School Administrators contract similarly covers 2023 through 2026, indicating that this unit's agreement also reached the end of its documented term in 2026. No successor agreement for this unit was located in public sources as of July 25, 2026.

The Teacher Aides contract and the non-teaching unit agreement are posted on district resources, but the current expiration dates for these units' active agreements were not clearly identified in the available public materials.

Annual budget vote and board election

The district holds its annual budget vote and board of education election in May. The most recent vote occurred on May 19, 2026, when voters approved the $176,560,406 budget for 2026-27 and authorized up to $9 million from capital reserves, according to local reporting. The district's budget page provides additional information on the 2026-27 budget.

The next annual budget vote and board election is expected in May 2027, though no specific date has been publicly scheduled as of July 25, 2026. Board members serve three-year terms, so the specific seats up for election in 2027 will depend on which current members' terms expire. That information is typically published by the district in advance of the election cycle.

Litigation calendar

The one material litigation matter identified, Matter of Cooke v. Mamaroneck Union Free School District, was closed by the Appellate Division's May 21, 2025 dismissal, according to the court's decision. No further court dates are pending in this matter. No other material litigation with scheduled court dates was identified in the available public record.

Program milestones

The district posted Universal Pre-K registration information for 2026-27, with an application window from February 2 through March 31, 2026, according to the district's registration page. This window has closed. The next UPK registration cycle for 2027-28 would be expected in early 2027, though no dates have been published as of July 25, 2026.

State oversight monitoring

No state fiscal stress designation or state monitor is active for the district. The State Comptroller's fiscal stress monitoring system publishes periodic updates. The State Education Department's monitor listing is also updated periodically. No specific date for the next release of updated designations has been identified.

Surprising insights

Several findings in this report are likely to be non-obvious to a well-informed local parent, even one who has lived in the area for years and follows district affairs.

The Village of Mamaroneck straddles two towns, and the town boundary determines school district membership. A property in the Village of Mamaroneck could be served by either the Mamaroneck Union Free School District or the Rye Neck Union Free School District, depending on which side of the town line it occupies. A buyer who assumes that a Village of Mamaroneck address guarantees enrollment in Mamaroneck schools could be mistaken. A municipal boundary change, such as a village annexation, does not by itself alter the school district boundary; the school district line can only be changed through a separate statutory procedure under New York Education Law.

The most recent graduation data on file is from the 2019-20 school year, and it provides only the cohort size of 407 students, not the graduation rate itself. A family looking for a current graduation rate will not find one in the available data. The 2019-20 cohort was in its final year during the first spring of pandemic-related school closures, which further limits its relevance to current conditions. No more recent graduation data is available on file.

The district does not operate a labeled gifted and talented program. The Civil Rights Data Collection for SY2021-22 shows no enrollment in gifted programs across the district's six schools, and the district's public materials do not describe a separate identification process, assessment instrument, referral timeline, or appeals procedure. Families seeking accelerated academic placement must look to course-level acceleration, such as the Grade 8 Algebra pathway, rather than a designated gifted program.

The district's AP proficiency rates in 2023-24 range from 59.6 percent in AP Calculus AB to 100.0 percent in AP Chemistry and AP Computer Science A, but the computed data provides no participation counts. A 100 percent proficiency rate in a subject with five test-takers represents a fundamentally different situation than the same rate in a subject with fifty test-takers, and the data on file cannot distinguish between these cases. Without knowing how many students sat for each exam, the proficiency rates cannot be interpreted as measures of broad program quality.

The most recent districtwide capacity and utilization study on file dates to 2017. No current building-by-building utilization report was located in district materials from 2024 through 2026. A family seeking to understand whether a specific elementary school is approaching capacity limits would need to request that data directly from the district, as it is not published in available materials.

Best fit: who this district serves well

A family seeking a self-contained K-12 district with a single secondary school pathway will find that structure here. The Mamaroneck Union Free School District operates its own elementary, middle, and high schools and does not pay tuition to send students to another district for any grade. Every student in the district feeds into the same middle school, Hommocks, and the same high school, Mamaroneck High School, regardless of which elementary attendance zone they live in. This eliminates a layer of uncertainty that exists in districts with multiple secondary schools and competing feeder patterns. A family for whom feeder certainty matters, knowing that an elementary school assignment will not later redirect a child to a different middle or high school, will find that the district's structure provides it.

A family interested in dual language education has an option that not all districts offer. The Dos Caminos Dual Language Program provides a Spanish-English instructional model with entry at kindergarten through an application, screening, and lottery process. This is the only districtwide alternative to zoned elementary assignment. However, the program's application materials do not mention sibling or twin preference in the lottery, and the screening criteria that determine eligibility for the lottery pool are not publicly enumerated. A family considering this pathway should understand that admission is not guaranteed and that the specific basis for selection is not fully described in public materials.

A student ready for college-level coursework has access to a range of Advanced Placement courses and dual enrollment opportunities. The 2023-24 AP proficiency rates show courses across science, mathematics, history, and computer science, with rates varying from 59.6 percent to 100.0 percent depending on the subject. Dual enrollment partnerships with Syracuse University, Iona College, SUNY Albany, Westchester Community College, and Siena College allow students to earn college credit for certain courses taken at Mamaroneck High School. Two original research programs, Original Science Research and Original Civic Research and Action, extend the academic ceiling further, though their specific structures and prerequisites are not fully described in public materials.

A family valuing moderate district scale will find it here. With 5,565 students across six schools in 2023-24, the district is neither a small rural system nor a large urban one. The four elementary schools feed into shared secondary schools, which means that elementary school placement is the primary point at which building-level differences could affect a family's experience.

A family needing pre-kindergarten has an option through the district's Universal Pre-K program at Central Elementary School. If applications exceed available seats, a lottery is conducted, and the program operates separately from the K-5 zoned enrollment system.

What the district does not currently offer, based on the available data: No International Baccalaureate programme is listed for any school in the district. No formal gifted and talented program is operated, according to the Civil Rights Data Collection for SY2021-22. No published numeric criteria exist for Grade 8 accelerated Algebra placement; the district describes the pathway but does not enumerate a test cutoff, GPA threshold, or the body that makes placement decisions. No current building-by-building capacity utilization data is publicly available; the most recent study dates to 2017. No school-level disaggregation of assessment data is available in the computed profile, which means a family cannot compare outcomes across the four elementary schools using the data on file. The graduation data on file is from 2019-20 and provides only cohort size, not a rate. Free and reduced-price lunch data, individualized education program counts, and English learner counts are all reported as missing, which means this report cannot describe how the district serves students along those dimensions.

Questions parents should ask

1. "Which school district serves this specific address?" For properties in the Village of Mamaroneck, the answer depends on which side of the town boundary the property occupies, as the village straddles the Town of Mamaroneck and the Town of Rye. Ask the district's Family Information Center.

2. "What are the current enrollment and capacity figures for each elementary school?" The most recent districtwide utilization study on file dates to 2017, and no current building-by-building report was located in district materials from 2024 through 2026. Ask the district's business office.

3. "How many students took each AP exam in 2023-24?" Proficiency rates are available but participation counts are not, which means a high rate could reflect a small number of test-takers. Ask Mamaroneck High School's counseling department.

4. "What is the current graduation rate?" The most recent graduation data on file is from 2019-20 and provides only cohort size, not a rate. Ask the district or consult the NYSED data portal.

5. "What criteria determine placement into Grade 8 accelerated Algebra?" Public materials describe the pathway but do not enumerate a test cutoff, GPA threshold, or the decision-making body. Ask Hommocks Middle School's mathematics department.

6. "What does the Dos Caminos dual language screening assess, and does the lottery include sibling preference?" The application materials describe a lottery but not the screening criteria or whether siblings receive priority. Ask the district's teaching and learning office.

7. "What are the free and reduced-price lunch rates, IEP rates, and English learner rates by school?" These figures are reported as missing in the computed data, which limits understanding of school-level variation. Ask the district or consult the NYSED data portal.

8. "Are there current plans for a boundary study or redistricting review?" No active process was identified in district documents through July 2026, but the 2017 Long Range Planning Study is the most recent analysis on the public record. Ask the Board of Education.

9. "Which specific MHS courses carry dual enrollment credit, and what are the fees?" Partner institutions are listed but the specific courses, credit amounts, and costs are not enumerated in public materials. Ask Mamaroneck High School's counseling department.

10. "What is the district's current chronic absenteeism rate, and how does it vary by school?" Only a district-level rate of 13 percent for 2022-23 is available. Ask the district.

11. "What is the appeals process if a family disagrees with a course placement decision?" The district's public materials do not describe an appeals process for accelerated placement outcomes. Ask the district's curriculum office.

12. "Does the Universal Pre-K program have capacity for all applicants, and what is the current waitlist status?" The program uses a lottery when applications exceed seats, with a mid-April deadline for the 2026 cycle. Ask the district's registration office.

Scope, method, and sourcing notes

This report draws on multiple federal, state, and local data sources to describe the Mamaroneck Union Free School District. Each source has a specific vintage and scope, and each carries limitations that affect what conclusions can be drawn.

Enrollment data comes from the National Center for Education Statistics Common Core of Data for the 2023-24 school year. This source provides total enrollment of 5,565 students, racial and ethnic composition, and the list of six schools operated by the district. It does not provide free and reduced-price lunch counts or rates, individualized education program counts or rates, or English learner counts or rates; all three are reported as missing in the computed data.

Assessment data is sourced from New York State Education Department data via a processed profile corpus. The computed data contains 65 distinct data series spanning 2006 through 2025. State assessment data points are present for 2006 through 2017. The most recent data points are Advanced Placement proficiency rates from the 2023-24 school year. A gap exists between 2017 and 2023-24, reflecting the cancellation of state assessments in spring 2020 and modified testing conditions in subsequent years. The AP data provides proficiency rates for the all-students group only, with no subgroup breakdowns. Participation counts are not provided, which means proficiency rates cannot be contextualized by how many students took each exam.

Graduation data is sourced from EDFacts ACGR, the Adjusted Cohort Graduation Rate, via the Urban Institute Education Data API for the 2019-20 school year. This is the most recent graduation data available on file. It provides a cohort size of 407 students but does not include the graduation rate itself. This data is several years old and reflects a cohort that was in its final year during the initial pandemic disruption.

Chronic absenteeism data is sourced from EDFacts Data Group 814 for the 2022-23 school year. The district-level rate is 13 percent. No school-level or subgroup breakdowns are available in the computed data.

Civil Rights Data Collection data from the US Department of Education for SY2021-22 provides AP enrollment totals by demographic category, Algebra I enrollment, suspension data, and gifted and talented reporting. This data is aggregated across six school-level rows and does not provide school-by-school breakdowns in the computed profile.

District-published materials, including budget documents, Board of Education minutes, the high school course catalog, the district's equity plan, a 2017-2018 high school profile, and facilities presentations, were reviewed for information on governance, programs, capacity, and boundaries. These materials vary in date and completeness.

Several categories of data that families might expect are not available in the computed profile. No long-run enrollment trend series was located; the district's own budget materials describe enrollment in qualitative terms without publishing a longitudinal series. No current building-by-building capacity utilization report was found; the most recent study dates to 2017. No school-level disaggregation of assessment or enrollment data is available. No published student growth score exists at the district level. Market figures are not included in this report; where such data is available from other sources, it is typically ZIP-level rather than district-boundary-precise. Child poverty data was unavailable; free and reduced-price lunch counts and rates are reported as missing. No destination or outflow study was located, meaning the district has not publicly analyzed where students go if they leave district schools or how many do so. The absence of these data points means that certain questions about the district cannot be answered from the information on file, and this report states those nulls rather than speculating.

About SchoolDecision.com

SchoolDecision.com publishes source-attributed profiles of US school districts and schools built from government data and official district publications.
