State of the School District: Ossining, NY

Summary Perspective

Ossining Union Free School District is a sustainability story. The district is not in turnaround, not in governance transition, and not under state accountability intervention. What it faces is a convergence of physical capacity strain and fiscal transition that will test the district's ability to maintain its current program while absorbing new debt, managing enrollment, and replacing expired federal funding with local revenue.

The district serves 4,993 students across six schools in 2023-24, operating a grade-center model where grade level, not street address, determines building assignment. This structure means every student in a given grade across the entire district attends the same school. The district contains a single high school, Ossining High School, which means every district-level secondary outcome is a measure of that one building. There is no between-high-school variation to analyze because there is only one.

On academics, the available data is narrow. The computed assessment series captures Advanced Placement proficiency rates for 2023-24 across several subjects, with rates ranging from 16.0 percent on AP Calculus AB to 80.0 percent on AP Biology among the reported cells. No New York State Regents exam results, no grades 3-8 state assessment data, and no subgroup breakdowns appear in the data on file. The most recent graduation data is from 2019-20, with a cohort of 352 students and no graduation rate percentage reported in the computed data. This data is several years old and reflects a cohort that was in its final year during the onset of the COVID-19 pandemic. The academic picture is therefore partial: a snapshot of AP performance for one recent year, with no trajectory analysis possible from the data provided.

The single most decision-relevant contextual fact is the capacity-to-debt pipeline. The district self-reports secondary classroom utilization at 100 to 107 percent, with lunchrooms, special-services spaces, and support functions operating in temporary areas, hallways, and stages. In 2024, voters approved a $210,215,771 facilities bond proposition by a margin of 788 votes to fund a new grades 7-8 school adjacent to Ossining High School. This bond will add to an existing debt load of $38,424,064 as of June 30, 2026, and to long-term obligations that include $328,388,003 in unfunded other post-employment benefits. The 2026-27 adopted budget of $186,337,089 uses $10,160,303 in appropriated fund balance and reserves to close the gap between recurring revenues and recurring expenditures. The unassigned fund balance has declined from $14,828,841 in 2021 to $7,146,692 in 2025. The tax levy for 2026-27 increased 2.43 percent, equaling the maximum allowable under New York's tax cap law, and no override was required.

This report describes fit rather than issuing ratings. It does not rate, rank, or recommend.

Key takeaways for families

• The district operates a grade-center model where a child's grade level, not their address, determines which school they attend. Every resident student in a given grade across the entire district attends the same building, which eliminates between-school variation at the elementary level by design.
• A Briarcliff Manor mailing address does not automatically determine school district assignment, because the district boundary and the municipal boundary are not the same lines. The only reliable way to confirm district assignment for a specific property is to consult the district directly or review official boundary records.
• The Dual Language program offers a limited number of kindergarten and grade-1 entry seats selected by lottery for the 2026-27 school year. The district does not publish seat counts, selection odds, a waitlist, or sibling priority on the accessible program page.
• Advanced Placement proficiency rates in 2023-24 ranged from 16.0 percent on AP Calculus AB to 80.0 percent on AP Biology among reported cells. No New York State Regents exam results, grades 3-8 assessment data, or subgroup breakdowns are available in the data on file.
• The most recent graduation data on file is from 2019-20, with a cohort of 352 students and no graduation rate percentage reported in the computed data. This data is several years old and reflects a cohort that was in its final year during the onset of the COVID-19 pandemic.
• The district was not identified for Comprehensive Support and Improvement, Additional Targeted Support and Improvement, or Targeted Support and Improvement for the 2025-26 school year. Its designation is "Local Support and Improvement," the state's model for districts not requiring targeted intervention.
• The chronic absenteeism rate for the district was 14.9 percent in the 2022-2023 school year, according to EDFacts Data Group 814. Chronic absenteeism is typically defined as missing 10 percent or more of enrolled school days, whether excused or unexcused.
• The district self-reports secondary classroom utilization at 100 to 107 percent, with lunchrooms and special-services spaces operating in temporary or improvised locations. A new grades 7-8 school is planned on a former church property adjacent to Ossining High School, funded by a $210,215,771 bond approved by voters in 2024.
• The 2026-27 adopted budget of $186,337,089 uses $10,160,303 in appropriated fund balance and reserves to close the gap between revenues and expenditures. The unassigned fund balance has declined from $14,828,841 in 2021 to $7,146,692 in 2025.
• The tax levy for 2026-27 increased 2.43 percent, equaling the maximum allowable under New York's tax cap law, and no 60 percent supermajority override was required. The district has not required an override in the recent budget cycles on record.
• The district spans portions of three towns with dramatically different tax rates per $1,000 of assessed value: $19.008 in Ossining, $135.097 in New Castle, and $1,073.916 in Yorktown for 2025-26. These differences reflect different assessment practices, not different tax burdens for comparable properties.
• The district carries $38,424,064 in outstanding debt as of June 30, 2026, and $328,388,003 in unfunded other post-employment benefits as of June 30, 2025. Moody's Investors Service assigns the district an Aa2 credit rating.

At a glance

The following table summarizes key dimensions of the Ossining Union Free School District based on the data available in this report. Where the computed data or body sections do not provide a figure, the entry reads "Not available." Numeric values are drawn from computed data where available; figures sourced from the district's own budget materials or self-reported facilities data are labeled accordingly. The table is a quick reference, not a substitute for the detailed analysis in the body sections above. Several cells reflect data that is several years old or incomplete: the graduation data is from 2019-20, the most recent on file, and no graduation rate percentage is provided in the computed data. The per-pupil spending figure is from FY2023, the most recent fiscal year available in the U.S. Census Bureau F-33 survey. The AP proficiency rates are from 2023-24 and represent only students who took AP exams, not the full student population. The capacity utilization figure is self-reported by the district and has not been independently verified in the materials on file.

How to read New York accountability

New York's accountability system under the Every Student Succeeds Act classifies schools and districts into tiers based on multiple indicators, including academic achievement, student growth, chronic absenteeism, and graduation rates. Comprehensive Support and Improvement, or CSI, is the most intensive tier, applied to schools identified as among the lowest-performing in the state. Targeted Support and Improvement, or TSI, applies to schools where one or more student subgroups are consistently underperforming. Additional Targeted Support and Improvement, or ATSI, is a further specification for schools where subgroup performance is particularly low. Districts not identified for any of these intervention tiers receive a "Local Support and Improvement" designation, meaning improvement activities are managed at the district level rather than through state-directed intervention.

The state also reports a Student Growth measure, which is intended to track changes in student performance over time rather than proficiency at a single point. For Ossining, a Student Growth measure was reported for the 2024-25 school year, though the specific result is not detailed in the computed data on file. The growth measure complements proficiency rates and other indicators but does not replace them.

New York's tax levy limit, established under Education Law section 2023-a, generally restricts the annual growth in a district's property tax levy to the lesser of 2 percent or the rate of inflation, with adjustments for growth in the tax base and certain capital exclusions. When a school district proposes a levy exceeding its calculated cap, it must secure approval from 60 percent of voters rather than a simple majority. If voters defeat the proposed budget, the district must adopt a contingency budget under Education Law section 2023, which cannot increase the levy above the prior year's level. The contingency mechanism provides no inflation factor or growth allowance, meaning a defeated budget has a direct fiscal consequence beyond specific spending reductions.

The available materials on file for this report do not address charter school availability or inter-district public school choice options specific to Ossining or its surrounding area. No charter schools operating within or adjacent to the district's boundaries are documented in the computed data or body sections, and no formal inter-district choice arrangements are described.

For Ossining specifically, the district was not identified for CSI, ATSI, or TSI for the 2025-26 school year and carries a "Local Support and Improvement" designation. The district's tax levy for 2026-27 increased 2.43 percent, equaling the maximum allowable levy under the cap, and no 60 percent supermajority override was required. The district has not required an override in the recent budget cycles on record.

What kind of district this is: governance and geography

Ossining Union Free School District is classified as a "union free school district" under New York Education Law Article 35, which governs districts organized under sections 1701 through 1726. The union free district is one of several district types recognized under New York law, and it is an independent entity: it is not subordinate to any other district and operates its own PK-12 program. The district serves grades PK and K-12 across six schools, all of which are open as of the 2023-24 school year. Total enrollment in 2023-24 was 4,993 students, according to data from the National Center for Education Statistics Common Core of Data. The district's NCES LEA ID is 3622020, and its headquarters are located in the Village of Ossining, NY 10562. The official district website publishes board meeting materials, budget documents, and public records.

Board of education: composition and elections

The board of education for a union free district may have between 5 and 9 trustee seats under New York Education Law section 1702. Ossining's board has 7 members. Board members are elected to 3-year terms in at-large elections, meaning each member represents the entire district rather than a specific geographic sub-area within it. The next scheduled board election is May 19, 2026. The district publishes board candidate biographies and debate information on its website ahead of elections. The at-large structure means that all voters in the district vote on all open seats, rather than voting only for a representative from a particular neighborhood or zone.

Taxing authority: who levies and who collects

The Ossining UFSD board of education adopts the annual budget, and the district itself levies the school tax. The Town of Ossining Receiver of Taxes bills and collects the tax on a combined town, county, and school bill, but this collection function is administrative: it does not change which entity levies the tax. The district, not the town or village, is the taxing authority.

Two state-law mechanisms constrain how much the levy may grow. The tax-cap formula in Education Law section 2023-a limits the annual levy increase to a calculated percentage tied largely to inflation and growth in the tax base. If voters defeat the proposed budget, the board must adopt a contingency budget under Education Law section 2023. A contingency budget may include only ordinary contingent expenses, such as teacher salaries and required benefits, legal obligations, and similar items. It may not include certain non-contingent expenditures such as new equipment, capital outlays beyond ordinary repair, or community-use expenses. Critically, the tax levy in a contingency budget cannot exceed the prior year's levy: there is no inflation factor or growth allowance applied. This means a defeated budget has a direct fiscal consequence beyond the specific spending reductions, because the district loses the ability to increase the levy at all for that year.

Budget approval and the voter referendum

The budget approval process places the decision with district voters. The board proposes a budget, and voters in the district vote on it in an annual election. If the budget is approved, the board adopts it as proposed. If it is defeated, the board must either adopt a contingency budget or, under certain circumstances, resubmit the budget for a second vote. If the second vote also fails, a contingency budget is required. The contingency budget mechanism is designed to ensure the district can continue operating, paying staff, meeting legal obligations, and maintaining essential services, while stripping out discretionary spending. The practical effect is that programs and expenditures classified as non-contingent are suspended or eliminated for that budget cycle. Election results for recent budget votes and board elections have been reported by local media.

Municipalities served and shared boundaries

The district's geographic footprint spans portions of several municipalities in Westchester County, as described on the district's about page. The Village of Ossining is served in its entirety. A portion of the Town of Ossining outside the village is also served. A portion of the Town of New Castle falls within the district. The western portion of the Village of Briarcliff Manor, including the Chilmark area, is served by Ossining UFSD, but this area is shared: the Briarcliff Manor Union Free School District also serves parts of the Village of Briarcliff Manor. This means that a Briarcliff Manor address does not automatically determine which school district a residence falls within, because the district boundary and the municipal boundary are not the same lines.

This distinction between municipal boundaries and school district boundaries is a recurring source of confusion for residents and prospective homebuyers in the Ossining area, as local reporting has noted. A house may have an Ossining mailing address but fall within a different school district, or a house with a Briarcliff Manor address may be assigned to Ossining schools. The only reliable way to confirm district assignment for a specific property is to consult the district directly or review official boundary records.

Feeder structure

Ossining UFSD operates a self-contained PK-12 system. It does not send students to, or receive students from, other districts for grade-span reasons. Students who begin their education in Ossining UFSD schools can, in principle, complete their entire PK-12 progression within the district without transferring to an outside district for any grade level. The district's membership in Putnam-Northern Westchester BOCES is a regional educational service cooperative arrangement, not a feeder relationship. BOCES provides shared services such as career and technical education, special education programs, and professional development to member districts, but students who attend BOCES programs remain enrolled in their home district for purposes of enrollment counting and accountability.

The district's six schools are: Anne M. Dorner Middle School, Brookside School, Claremont School, Ossining High School, Park School, and Roosevelt School. All six are currently open, according to NCES CCD data processed for the 2023-24 year.

How district boundaries can change

Ossining UFSD's boundaries cannot be altered by a municipal action alone. If the Village of Ossining or the Town of Ossining were to annex or transfer territory, that municipal boundary change would not automatically move the school district boundary. Instead, school district boundaries in New York can only be changed through a formal proceeding before the New York State Commissioner of Education.

The primary mechanism for adding territory to a union free school district is governed by New York Education Law section 1705. The process begins with a petition by qualified voters or residents of the affected area. The Commissioner of Education then reviews the petition and, if the statutory criteria are met, issues an order. The order must be approved by a successful referendum of voters in both the area proposed for annexation and the receiving district. Only after both referenda pass does the territory transfer take effect.

An alternative mechanism is centralization, governed by Education Law sections 1801 through 1805. In a centralization proceeding, the Commissioner may dissolve Ossining UFSD and merge it into a new central school district. This process also requires a successful voter referendum. Centralization is a more sweeping change than annexation because it would eliminate the existing district as a legal entity and create a new one in its place.

Both mechanisms require voter approval at the referendum stage. The Commissioner of Education does not have unilateral authority to redraw district boundaries; the statutory framework requires voter consent. This means that boundary changes are rare and require sustained political support from the affected communities.

Academic outcomes: the evidence base

The computed assessment data for Ossining Union Free School District encompasses 52 series spanning 2006 through 2025, drawn from New York state assessment records processed through the profile corpus. The most recent reported data points are from the 2023-24 school year. These series capture Advanced Placement exam proficiency rates across multiple subjects and grade levels. State assessment testing was cancelled in 2020 due to the COVID-19 pandemic, producing a gap in the longitudinal record for that year. No data exists for that testing window, and any analysis of trends over time must account for this interruption.

What the assessment data measures

The series on file reports proficiency rates on Advanced Placement exams. AP exams are standardized tests administered by the College Board, designed to measure mastery of college-level coursework in specific subjects. Each exam is scored on a scale of 1 to 5. A score of 3 or higher is generally considered a passing or proficient score and may qualify a student for college credit at many institutions, though credit policies vary by college and subject. The proficiency rate reported here represents the percentage of students who took a given AP exam and achieved a score of 3 or higher. It is not the percentage of all students in a grade who demonstrated proficiency, because the denominator is exam-takers only, not total enrollment. Students who did not take an AP exam are not included in the calculation.

What this data does not measure: AP proficiency rates reflect only the performance of students who elected to enroll in AP courses and sat for the exams. They do not capture outcomes for students who did not take AP exams, nor do they measure academic growth over time, college enrollment or completion, career readiness, or social-emotional outcomes. They also do not reflect performance on New York State Regents exams, which are the state's required high school assessments, or on the state's grades 3-8 English language arts and mathematics assessments. The AP data provides a view of one segment of the high school academic program, not a comprehensive portrait of district-wide performance. Families seeking a fuller picture would need to consult additional data sources, including the district's teaching and learning page and the NYSED district profile.

AP proficiency rates, 2023-24

The following proficiency rates were reported for the 2023-24 school year:

• AP Biology: 55.6% proficiency among Grade 11 test-takers and 80.0% among Grade 12 test-takers. The difference between grade levels may reflect course sequencing, student self-selection, or other factors the data alone cannot explain.
• AP Calculus AB: 16.0% proficiency among Grade 12 test-takers. This is the lowest reported proficiency rate across the subjects on file.
• AP Calculus BC: 52.4% proficiency among Grade 12 test-takers. Calculus BC is a more advanced course than Calculus AB, covering additional topics, and the two exams are taken by different student populations.
• AP Computer Science A: 40.0% proficiency among Grade 11 test-takers and 33.3% among Grade 12 test-takers. Data for Grade 9 was reported as missing.
• AP Environmental Science: 42.9% proficiency among Grade 11 test-takers and 61.5% among Grade 12 test-takers. Data for Grade 10 was reported as missing.
• AP Language and Composition: 62.9% proficiency among Grade 11 test-takers.
• AP Chemistry: Data for Grade 11 was reported as missing.

Where both Grade 11 and Grade 12 results are available for the same subject (Biology, Computer Science A, Environmental Science), Grade 12 proficiency rates exceed Grade 11 rates. The data does not indicate whether this pattern reflects additional instructional time, differences in which students take the exam at each grade level, or other factors. Mathematics proficiency rates differ substantially between Calculus AB (16.0%) and Calculus BC (52.4%), though these are different exams covering different scopes of material. Missing data for several subject-grade combinations means no proficiency rate can be reported for those cells.

Level versus trajectory

The computed data provides proficiency levels for 2023-24. Trajectory, the question of whether performance is improving, declining, or stable over time, requires multi-year comparisons. While the assessment series metadata indicates data collection spanning 2006 through 2025, the specific data points available in the computed series are from 2023-24. The 2020 testing cancellation due to the pandemic created a gap in the longitudinal record. Without multiple years of comparable data points visible in the computed series, a trajectory analysis cannot be constructed from the data on file. What can be reported is the current level of AP proficiency by subject and grade for the most recent available year.

Subgroup data

The computed assessment series reports results for all students only. No subgroup breakdowns by race, ethnicity, economic status, English learner status, or disability status are available in the AP proficiency data on file. The enrollment data for 2023-24 shows the district's student composition: of 4,993 enrolled students, 3,366 (67.4%) were Hispanic, 895 (17.9%) were White, 418 (8.4%) were Black, 138 (2.8%) were Asian, 170 (3.4%) were of two or more races, 2 (0.04%) were American Indian or Alaska Native, and 2 (0.04%) were Native Hawaiian or Pacific Islander. Free and reduced-price lunch counts, Individualized Education Program data, and English learner data were all reported as missing for 2023-24.

Graduation data

The most recent graduation data on file is from the 2019-20 school year, sourced from EDFacts Adjusted Cohort Graduation Rate data via the Urban Institute Education Data API. The cohort size was 352 students. No graduation rate percentage is provided in the computed data. This data is several years old and reflects a cohort that was in its final year of high school during the onset of the COVID-19 pandemic. It should not be treated as indicative of current graduation outcomes.

Chronic absenteeism

The chronic absenteeism rate for the district was 14.9% in the 2022-2023 school year, according to EDFacts Data Group 814. Chronic absenteeism is typically defined as missing 10% or more of enrolled school days, whether excused or unexcused. This rate represents all students in the district. The New York State Education Department provides additional context on chronic absenteeism through its accountability framework.

Accountability status

For the 2025-26 school year, Ossining Union Free School District was not identified for Comprehensive Support and Improvement (CSI), Additional Targeted Support and Improvement (ATSI), or Targeted Support and Improvement (TSI). The district's designation is "Local Support and Improvement," which is the state's model for districts not requiring targeted intervention. Under this model, improvement activities occur at the local level rather than through state-directed intervention. A Student Growth measure was reported for the 2024-25 school year, though the specific result is not detailed in the computed data. The ESSA accountability system in New York uses multiple indicators to identify schools for support levels, and the absence of a CSI, ATSI, or TSI designation means the district was not flagged for those tiers of intervention in the 2025-26 cycle.

What the data does not capture

The assessment data on file provides a partial view of academic outcomes. It does not include New York State Regents exam results, which are the state's required high school assessments. It does not include grades 3-8 state assessment results in English language arts and mathematics. It does not include college enrollment, persistence, or completion data. It does not include measures of social-emotional learning, career and technical education outcomes, or other indicators of student well-being. The AP proficiency rates capture one dimension of the high school academic program: how students who elected to take AP exams performed on those specific tests in 2023-24. The high school course guide may provide additional context on which AP courses are offered and how they fit into the broader academic program, but course offerings are not the same as measured outcomes.

Inside the district: variation between schools

The Ossining Union Free School District operates six schools, all carrying an open lifecycle status in the 2023-24 data. These are Anne M Dorner Middle School, Brookside School, Claremont School, Ossining High School, Park School, and Roosevelt School. Total enrollment across the district was 4,993 students in 2023-24, according to the NCES Common Core of Data.

A defining structural feature of this district is that it contains a single high school. Ossining High School is the only secondary school in the district, which means that every district-level measure of high school outcomes is, by definition, a measure of that one school. There is no spread between high schools to report, because there is only one. For families trying to understand how outcomes vary across secondary schools within district boundaries, the answer is that no such variation exists at the high school level. The district average and the school-specific figure are the same number.

The Advanced Placement proficiency data on file for 2023-24 illustrates this point. The available records show district-level AP proficiency rates across multiple subjects and grade levels. For AP Biology, 55.6% of 11th-grade test-takers and 80.0% of 12th-grade test-takers achieved proficiency in 2023-24. For AP Calculus AB, 16.0% of 12th-graders achieved proficiency. For AP Calculus BC, 52.4% of 12th-graders achieved proficiency. For AP Computer Science A, 40.0% of 11th-graders and 33.3% of 12th-graders achieved proficiency. For AP Environmental Science, 42.9% of 11th-graders and 61.5% of 12th-graders achieved proficiency. For AP Language and Composition, 62.9% of 11th-graders achieved proficiency. Proficiency data for AP Chemistry at grade 11, AP Computer Science A at grade 9, and AP Environmental Science at grade 10 is reported as missing for the same year.

Because these figures are aggregated to the district level and the district operates one high school, they represent Ossining High School's results directly. They cannot show variation between high schools, but they do reveal variation across subjects and grade levels within the single school. The gap between 11th-grade and 12th-grade AP Biology proficiency rates is 24.4 percentage points. The gap between AP Calculus AB and AP Calculus BC among 12th-graders is 36.4 percentage points. The range across all reported subjects and grades runs from 16.0% to 80.0%. These differences represent within-school variation rather than between-school variation. They may reflect which students self-select into each course, the sequencing of instruction, the difficulty of the exam, or other factors that the available data does not separate. The data shows the outcomes but not the mechanisms behind the spread.

At the elementary and middle school levels, the district has multiple buildings. Anne M Dorner Middle School is identified by name as a middle school in the NCES data. Brookside School, Claremont School, Park School, and Roosevelt School are also listed as open. The district's website maintains separate curriculum pages for middle school learning and high school learning, confirming a multi-level organizational structure. However, the available computed data does not include school-level assessment results for any of these schools. Without school-level outcome measures, it is not possible to report how performance varies from one school to another at the elementary or middle school level, or how any individual school compares to the district aggregate. The assessment series on file are aggregated to the district rather than broken out by building.

Several other data points that would help characterize variation between schools are also absent from the available records. 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. Without these measures, the available data cannot describe how economic need, disability services, or language support vary across the district's six schools. The district's race and ethnicity data is reported at the district level only, showing a student population in 2023-24 that is 67.4% Hispanic, 17.9% White, 8.4% Black, 2.8% Asian, 3.4% two or more races, and less than 1% American Indian or Alaska Native and Native Hawaiian or Pacific Islander. This data does not break down by individual school.

Families seeking school-level outcome data beyond what appears here can consult the New York State Education Department's district profile page and the state's ESSA accountability report for the district, both of which provide building-level data. Neither source is summarized in the data on file for this report, and specific figures from those sources are not cited here.

Advanced academics and pathway access

The advanced academic infrastructure in the Ossining Union Free School District centers on two mechanisms: an Advanced Placement program at Ossining High School and a selective science research sequence that connects students to university credit through a dual-enrollment partnership. The available data describes AP participation in demographic detail for the 2021-22 school year, identifies the research program's admissions structure and credit ceiling, and confirms that the Civil Rights Data Collection captured Algebra I and gifted enrollment data for the same year. Specific placement criteria for accelerated middle school math and gifted identification are not documented in the sources available to this report.

Advanced Placement enrollment and breadth

According to the US Department of Education Civil Rights Data Collection for SY2021-22, Ossining reported 373 Advanced Placement enrollments across its schools. These enrollments represent students registered in AP courses, not students who took AP exams, and the CRDC does not report exam performance or passage rates.

The racial and ethnic breakdown of AP enrollment was as follows. Hispanic or Latino students accounted for 172 enrollments, comprising 55 male and 117 female students. White students accounted for 127 enrollments, comprising 59 male and 68 female students. Asian students accounted for 34 enrollments, split evenly at 17 male and 17 female. Black students accounted for 20 enrollments, comprising 12 male and 8 female. Students of two or more races accounted for 19 enrollments, comprising 8 male and 11 female. Native Hawaiian or Other Pacific Islander students accounted for 1 enrollment, female. American Indian or Alaska Native students accounted for 0 enrollments.

The CRDC also reported AP enrollment by special population status within those 373 enrollments. Two English Learner students were enrolled in at least one AP course. Five students with disabilities under IDEA were enrolled in at least one AP course. Twenty-five students with Section 504 plan accommodations were enrolled in at least one AP course. These counts overlap with the racial and ethnic categories above; a student appears in both their racial category and any applicable special population category.

Ossining High School's counseling department publishes a course guide listing available courses, and the high school maintains an AP exams information page. The specific AP subjects offered and their prerequisites are detailed in those resources, which are maintained by the district and were not separately analyzed for this report.

Selective admissions and the academic ceiling

The Fundamentals of Science Research program at Ossining High School operates under selective admissions, according to the district's program documentation. The science research department page on the high school website describes the program's structure. Students who progress through the research sequence become eligible for Science Research in the High School, a program administered in partnership with the University at Albany. Through this partnership, students can earn up to 12 University at Albany credits. This dual-enrollment arrangement represents the highest documented academic ceiling in the available data: a student who completes the full research sequence can accumulate transferable credit from a State University of New York four-year institution while still enrolled in high school.

No International Baccalaureate program is referenced in the acquired research or computed data for this report. The absence of an IB Diploma Program or IB Career-related Program in the available sources means that the AP curriculum and the University at Albany research partnership together define the upper boundary of advanced coursework documented within the district.

Grade 8 Algebra I placement

The CRDC collected Algebra I enrollment data for Ossining in the 2021-22 school year across six school-level records. The specific number of eighth-grade students enrolled in Algebra I, and the criteria by which they were selected for that placement, are not available in the data provided for this report. The district's mathematics department page and middle school learning page outline the district's curricular framework for mathematics, but the placement mechanics that determine which students accelerate to Algebra I before ninth grade are not specified in the available sources. Families seeking to understand these criteria would need to consult the district's counseling department or published placement policies directly.

Gifted and talented identification

The CRDC collected gifted and talented enrollment data for Ossining in the 2021-22 school year across six school-level records. The specific identification counts and the method by which the district determines gifted placement are not available in the data provided. The New York State Education Department publishes a framework for gifted and talented education in New York, and the district maintains a student enrichment opportunities page that lists programs beyond the standard curriculum. The specific assessments, teacher referrals, or other criteria Ossining uses to identify students for gifted services are not documented in the sources available to this report.

Honors course structure and detracking

The district maintains a district equity page and a multi-tiered systems of support page on its website, both of which address the district's approach to academic access and student support. The available data does not document any specific proposal to restructure honors-level courses, eliminate tracked course sequences, or change the criteria by which students are sorted into accelerated versus standard sections. Without board minutes, policy proposals, or documented community debate in the provided sources, this report cannot describe the substance, status, or opposing positions of any detracking or course-leveling initiative in the district.

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

How an address becomes a school seat

Ossining Union Free School District operates a districtwide grade-center model rather than a set of neighborhood elementary attendance zones. Once a family establishes residency within the district, the child's grade level, not their street address, determines which building they attend. The published sequence is as follows: Park School for pre-K and kindergarten, Brookside School for grades 1 and 2, Claremont School for grades 3 and 4, Roosevelt School for grade 5, Anne M. Dorner Middle School for grades 6 through 8, and Ossining High School for grades 9 through 12. The district describes this sequence on its "About Our District" page for new families, but that page does not itself phrase the sequence as a legal guarantee of placement (source).

This grade-center structure has a practical consequence for a home buyer. In a traditional neighborhood-zoned district, two homes a quarter-mile apart might feed to different elementary schools and, depending on the feeder pattern, potentially different middle or high schools. In Ossining, every resident student in a given grade across the entire district attends the same building. There are no competing elementary attendance zones to compare when evaluating one Ossining address against another. The question is not which school a particular house feeds to, but whether the district's grade-center sequence itself remains stable, and whether capacity exists to serve every enrolled student within it.

One exception to the grade-determined placement is the Dual Language program. For the 2026-27 school year, the district states that only a limited number of Kindergarten and grade-1 Dual Language entry seats are available and that students are selected by lottery. The district does not publish seat counts, selection odds, a waitlist, or sibling priority on the accessible program page. A family seeking Dual Language placement therefore faces an element of uncertainty that does not apply to the standard grade-center track (source).

Whether a grade-center sequence guarantees a specific middle and high school

Because the district operates a single secondary pathway, all resident students who complete Roosevelt School in grade 5 proceed to Anne M. Dorner Middle School, and all who complete middle school proceed to Ossining High School. There is no competing middle school or high school within the district to which a student might be reassigned. The district lists six schools in total, all with a lifecycle status of "open" in the NCES Common Core of Data: Anne M. Dorner Middle School, Brookside School, Claremont School, Ossining High School, Park School, and Roosevelt School. No additional buildings are listed as closed, pending, or alternative.

The district does not publish separate elementary attendance-zone or feeder maps on its public-facing pages, and the grade-center page does not frame the sequence as a legal guarantee. In practice, the mechanism is stable because it is structural: the district has one building per grade band, so there is nowhere else within the district to send a resident student at a given grade level. The risk to this stability is not reassignment to a different school of the same type, but rather capacity-driven changes to the grade-center structure itself, such as splitting a grade band across multiple buildings or repurposing a building.

Capacity pressure by building

The district reports capacity strain concentrated at the secondary level. According to the district's own facilities and bond page, secondary classroom utilization stands at 100 to 107 percent. The district also reports that lunchrooms cannot support students without scheduling compromises, and that special-services and support uses are operating in temporary areas, hallways, and stages. These figures are self-reported by the district and have not been independently verified by an external auditor in the materials on file (source).

The capacity pressure specifically affects Anne M. Dorner Middle School and Ossining High School. The district's bond plan addresses what it describes as Anne M. Dorner Middle School space challenges and proposes expanding secondary classrooms and support space at a former church property adjoining Ossining High School. The elementary grade-center buildings, Park, Brookside, Claremont, and Roosevelt, are not identified in the available materials as operating above capacity, though no building-by-building utilization breakdown was found in the research on file.

The bond and new construction pipeline

The district has proposed a bond to fund a new grades 7-8 school on the former church property adjacent to Ossining High School. The plan involves connecting the existing church building to a new three-story classroom addition on the former rectory site. The district states that the project addresses current Anne M. Dorner Middle School space

Fiscal health and the tax picture

The Ossining Union Free School District operates within a fiscal framework that relies heavily on local property taxes, a structure common in Westchester County but one that creates a direct line between district budgeting decisions and household tax bills. Understanding the district's financial position requires examining how revenue is generated, how it is spent, and how structural balance is maintained or strained over time.

Per-pupil spending and revenue mix (FY2023)

According to the U.S. Census Bureau Annual Survey of School System Finances (F-33) for FY2023, the district's current spending per pupil was $29,766, of which $19,893 was directed to instruction. Current spending excludes capital outlay and debt service, capturing the day-to-day cost of operating schools. The instructional share represents approximately 67 percent of current spending, a proportion consistent with New York suburban districts where benefits, transportation, and central administration absorb a substantial portion of non-instructional expenditures. Total revenue for FY2023 was approximately $162.2 million against total expenditures of approximately $167.7 million, meaning the district spent more than it took in that year when all funds are counted.

The revenue mix for FY2023 was 62.8 percent local, 32.2 percent state, and 5 percent federal. The local share of 62.8 percent reflects the district's dependence on property taxes, a structure that ties school revenue directly to the assessed value of real property within district boundaries. The state share of 32.2 percent flows primarily through foundation aid and categorical grants allocated under New York's school aid formula, which weighs district wealth, student need, and regional cost factors. The federal share of 5 percent includes Title I, IDEA, and other programs, and was temporarily elevated during the pandemic years by ESSER (Elementary and Secondary School Emergency Relief) grants that have since expired.

Adopted budget and structural balance

The district's adopted budget for 2026-27 totals $186,337,089, a 4.3 percent increase over the prior year's budget of $178,662,726, according to the district's own figures. The district states that this budget is structurally balanced, meaning recurring revenues are presented as sufficient to cover recurring expenditures without relying on one-time resources. However, the same budget materials show that $10,160,303 in appropriated fund balance and reserves is being used to close the gap between revenues and expenditures. This means that if those reserve funds were removed, recurring revenues alone would not fully cover recurring costs in the adopted budget. The district's own budget materials caution against using one-time funds for ongoing salaries, acknowledging the structural risk this practice creates.

The district does not publish quantified out-year operating gap or fund balance projections in the cited budget materials. Materials outline a three-year transition plan and a capital program, but without specific dollar projections for future years, residents cannot independently assess whether the structural gap will narrow, persist, or widen.

Federal pandemic relief and its expiration

When federal ESSER grants ended, the district faced the loss of programs that had been supported by temporary federal funding. According to district budget materials, previously grant-funded programs are being sustained through year one of a three-year transition into the general budget. The 2026-27 budget includes an $829,557 appropriation specifically for grant-funding loss, meaning the district is absorbing part of the cost of continuing these programs with local funds. No specific program eliminations are listed in the cited presentations, though the three-year transition framework implies that the full cost will eventually need to be absorbed into the operating budget or the programs reduced.

Reserves and fund balance

The unassigned general-fund balance, a key indicator of a district's financial cushion, stood at $7,146,692 as of June 30, 2025, equal to 4.52 percent of gross general-fund expenditures, according to the New York State Office of the State Comptroller. The trend over five years reveals a significant shift. In 2021, the unassigned balance was $14,828,841, or 12.22 percent of expenditures. In 2022, it dropped sharply to $6,061,594 (4.63 percent), then recovered modestly to $6,680,120 (4.72 percent) in 2023, $7,210,633 (4.79 percent) in 2024, before dipping slightly to $7,146,692 (4.52 percent) in 2025. The 2022 decline coincides with the period when the district was deploying federal pandemic relief funds and may have drawn on reserves to bridge gaps. The modest recovery since 2022 has not returned the balance to its 2021 level, and the 2025 figure represents a slight decline from 2024.

Debt, pensions, and OPEB

The district carries $38,424,064 in outstanding debt as of June 30, 2026, according to fiscal advisor materials. Debt service for 2026-27 is budgeted at $9,955,474, approximately 5.34 percent of the adopted budget. In 2024, voters approved a $210,215,771 facilities bond proposition by a margin of 788 votes (1,126 yes to 338 no), which will add to the district's debt obligations in coming years as projects are executed and bonds are issued.

Moody's Investors Service assigns the district an Aa2 credit rating, which it has affirmed. This rating reflects the agency's assessment of the district's creditworthiness and affects the interest rates the district pays when it borrows. A higher rating generally translates into lower borrowing costs, which reduces the total cost of capital projects to taxpayers over the life of the bonds.

The district also carries substantial long-term obligations for other post-employment benefits (OPEB). As of June 30, 2025, the total OPEB liability was $328,388,003, funded on a pay-as-you-go basis, meaning the district pays retiree health benefits as they come due rather than pre-funding them. Employer pension contributions for FY2024-25 were $1,609,528 to the New York State and Local Retirement System (ERS) and $6,187,198 to the Teachers' Retirement System (TRS). These are recurring obligations that compete with instructional spending for budget dollars.

Tax levy limit and override history

For 2026-27, the district's tax levy is $110,564,402, a 2.43 percent increase that equals the district's maximum allowable tax levy under New York's tax cap law. No 60 percent supermajority override was required, meaning the levy increase stayed within the cap calculated for the district. New York's tax cap law generally limits the annual growth in the property tax levy to the lesser of 2 percent or the rate of inflation, with adjustments for growth in the tax base and certain capital exclusions. When a district proposes a levy exceeding its cap, it must secure approval from 60 percent of voters rather than a simple majority. Ossining has not required an override in the recent budget cycles on record.

How the levy becomes a household tax bill

The connection between the district's tax levy and an individual household's tax bill involves several steps. The district determines the total amount it needs to raise through property taxes, which is the levy. This levy is then distributed across all taxable properties in the district based on their assessed values. However, the Ossining Union Free School District spans portions of three towns: Ossining, New Castle, and Yorktown. Each town assesses property differently, and the tax rate per $1,000 of assessed value varies accordingly.

For the 2025-26 school year, the tax rate per $1,000 of assessed value was $19.008347 in the Town of Ossining, $135.096649 in the Town of New Castle, and $1,073.916325 in the Town of Yorktown, according to Westchester County tax rate data. These dramatically different rates do not mean that Yorktown property owners pay 56 times more than Ossining property owners for the same house. Rather, they reflect different assessment practices. The Town of Ossining assesses property at a higher fraction of market value, so a lower rate per $1,000 of assessed value produces a comparable tax bill. Yorktown's assessments are at a much lower fraction of market value, requiring a higher rate per $1,000 to produce the same revenue. The equalization process ensures that properties of equal market value across towns contribute proportionally to the district levy, regardless of the nominal assessment level.

Over the five-year period from 2021-22 to 2025-26, the Town of Ossining rate decreased from approximately $25.191 to $19.008 per $1,000, while the district levy moved from roughly $103.3 million to $107.9 million, dipping mid-period before rising in the last two years. The decline in the Ossining tax rate despite an increasing levy suggests that the town's total assessed value grew faster than the levy, spreading the tax burden across a larger base.

For comparison, neighboring districts show similar patterns driven by the same town assessment practices. Briarcliff Manor UFSD, which also draws from the Town of Ossining, had a rate of $18.093729 per $1,000 for 2025-26. Croton-Harmon School District, drawing from the Town of Yorktown, had a rate of $893.841413 per $1,000.

Top taxpayers and concentration

The district's tax base includes several large commercial properties. Con Edison Co of N Y leads the 2026 tax roll with $300,156,200 in full valuation, followed by GGIF Hudson LLC at $67,471,200, Harbor Square Crossings LLC at $56,649,000, Urstadt Biddle Properties Inc at $49,904,900, and the State of New York at $43,086,900. The concentration of substantial valuation in utility and commercial properties means that changes in the assessment or tax-exempt status of these properties could have a measurable effect on the tax burden borne by residential property owners. If a major taxpayer successfully challenges its assessment or receives a tax exemption, the resulting revenue shortfall would need to be absorbed by other taxpayers or offset by spending reductions.

Recent budget and bond vote results

The district's budget and bond propositions have passed in each recent year on record. In 2019, the annual school budget passed. In 2023, the budget passed by 1,060 votes (1,394 yes to 334 no). In 2024, voters approved both the annual budget and a $210,215,771 facilities bond proposition by 788 votes (1,126 yes to 338 no). In 2025, the budget of $178,662,726 passed by 623 votes (846 yes to 223 no). In 2026, the budget of $186,337,089 passed by 611 votes (895 yes to 284 no). No upcoming money measures beyond the adopted 2026-27 budget are identified in the available district materials. The 2024 bond represents a financial commitment that will shape the district's debt profile as projects proceed and bonds are issued against the authorization.

The municipal and land-use context

Ossining Union Free School District, NCES LEA ID 3622020, serves 4,993 students in the 2023-24 school year across territory in Westchester County, New York. The district overlaps with multiple municipal jurisdictions, including the Town of Ossining and the Village of Ossining. Understanding what is and is not happening at the municipal and land-use level requires separating matters that directly alter district boundaries or budgets from those that occur nearby without such effects.

Current status of district structural changes

As of July 2026, no active proceedings to change Ossining UFSD's boundaries through merger, annexation, or dissolution have been identified. Checks covered the district's own website for board and budget materials and any reorganization references, the Town of Ossining's project archive for Election District 17 and 20 annexation matters, Briarcliff Manor's annexation materials, the Town of Greenburgh's Edgemont incorporation records, and NYSED guidance and decisions for any Ossining UFSD merger or annexation filings. None were found. No external funding-body disputes have been identified, and the district's budgeting proceeds through its voter approval process without contested oversight from an external authority.

Historical annexation proceedings: Election Districts 17 and 20

In March 2014, the Town of Ossining published findings related to a proposed annexation of Election Districts 17 and 20. This matter is documented in the Town of Ossining's projects archive. Concurrent reporting from 2014 describes a related annexation dispute involving Briarcliff Manor. Briarcliff officials were reported to be considering court action over an annexation bid, and the proposal was reported as potentially heading to court. A reader opinion piece published in The Journal News in March 2014 characterized the outcome as a loss for Ossining in the Briarcliff annexation plan. Briarcliff Manor maintains a public webpage on annexation. These matters date to 2014 and are archived as completed projects by the Town of Ossining. No subsequent filings or proceedings have been identified that would reopen or extend these annexation questions as they pertain to Ossining UFSD.

The fiscal positions of the parties during the 2014 proceedings are not detailed in the available district-level research. The Town of Ossining's findings document represents the town's assessment of the proposed annexation. Briarcliff Manor's consideration of court action represents that municipality's posture. The specific fiscal arguments advanced by each party, including projected changes to tax base, enrollment, or service obligations, are not documented in the materials available for this report.

Westchester County affordable housing settlement

Westchester County was subject to a federal affordable housing settlement originating from a 2009 consent decree addressing claims of housing discrimination. County Executive George Latimer announced the termination of this settlement on August 4, 2021. The settlement operated at the county level through county government channels. No Ossining UFSD-specific mandate or enforcement requirement is documented in connection with this settlement. The district was not a party to the consent decree, and no district-level obligation arose from its termination.

Separately, the Village of Ossining maintains an affordable housing program with published rules and regulations. A Westchester County affordable housing project located in Ossining received an award recognition. These operate through municipal and county planning and development channels. They do not constitute school district mandates, and no mechanism transfers housing compliance obligations from the county or village to the school district.

Nearby municipal incorporation: Town of Greenburgh and Edgemont

The Town of Greenburgh has published incorporation information related to a proposed incorporation of the Edgemont community. The Edgemont community organization maintains records documenting this incorporation effort. This matter is geographically separate from Ossining UFSD's boundaries. The incorporation of Edgemont as a new village or municipality within the Town of Greenburgh would not alter Ossining UFSD's enrollment, tax base, or governance structure. It is a nearby municipal governance question that does not bear on this district.

How the district's funding relates to municipal fiscal conditions

The district's fiscal relationship to its municipalities operates through a specific mechanism. The Board of Education proposes an annual budget. District voters approve or reject that budget at the ballot box. The district independently levies property taxes within its boundaries to fund the approved budget. This means that the fiscal health of the Town of Ossining and the Village of Ossining does not flow through a municipal appropriation to the school district. Municipal fiscal conditions affect shared taxpayers indirectly, because property owners pay both municipal taxes and school taxes, but the school district's revenue is not determined by a municipal budget decision. The New York State Office of the State Comptroller publishes guidance on financing education that describes this framework.

Recent audited financial statements for the Town of Ossining (2025) and the Village of Ossining (2024) are published and publicly available. These documents reflect municipal fiscal conditions. They do not represent a funding dependency on the school district, nor does the school district depend on municipal appropriations for its operating revenue.

What municipal changes would affect this district

Several categories of structural change could, in principle, affect Ossining UFSD. Each operates through a distinct mechanism.

School district merger or annexation in New York follows a formal legal process. The New York State Department of State publishes a guide to consolidation, dissolution, and annexation that outlines these procedures. NYSED maintains a regionalization FAQ addressing questions about district regionalization efforts. The New York State United Teachers organization publishes a fact sheet on school district mergers and consolidations. Under these frameworks, a merger or annexation would require filings with NYSED, potential voter referenda in affected districts, and state-level approval. Such a change would alter the district's enrollment, tax base, and governance. No such filings have been identified for Ossining UFSD.

Municipal boundary changes, such as one municipality annexing territory from another, can intersect with school district boundaries. In New York, school district boundaries are established separately from municipal boundaries, but territory changes can raise questions about which district serves affected areas. The 2014 annexation proceedings involving Election Districts 17 and 20 illustrate this intersection. Those proceedings concluded without altering Ossining UFSD's current boundaries.

Housing development and land-use decisions within district boundaries affect the district through enrollment and tax base. New residential construction can increase the number of students the district serves, which affects per-pupil costs, facility capacity, and staffing. The district's facilities page documents its physical infrastructure. Property tax revenue, which the district levies directly, responds to changes in assessed valuation driven by development. The district's budget for 2026-27, as presented on its website, reflects this voter-approved revenue and expenditure framework.

The district has also engaged in borrowing. A notice of sale for $12,500,000 in district obligations is documented through fiscal advisory services. Bond issuance allows the district to finance capital projects, with repayment structured through future property tax levies approved by voters. This is a district-level fiscal action, not a municipal one, but it illustrates how the district independently manages its capital financing outside of municipal budget processes.

Real estate and the price of admission

The computed home value index for the Ossining Union Free School District area is $729,175 as of April 30, 2026, based on Zillow ZHVI data across three ZIP codes that overlap the district. The rent index is $3,618 as of the same date, based on one ZIP code. These figures are ZIP-level approximations; ZIP boundaries do not align with district boundaries, and the underlying allocation uses the NCES-ZCTA relationship file to weight ZIP-level data to the district. The district encompasses portions of four ZIP codes: 10510, 10520, 10545, and 10562.

No current official rental-vacancy rate is available. The Village of Ossining's planning department points to a 2018 housing vacancy analysis, but no 2024-2026 count was found in the records reviewed.

Residential development pipeline

Four residential projects are in active development within the Village of Ossining, totaling 349 proposed or under-construction units.

Station Plaza at 30 Water Street is under construction with 109 units: 108 income-restricted apartments plus one live-in superintendent unit, with 40 one-bedroom, 60 two-bedroom, and 9 three-bedroom units. Apartments are restricted to households at 30%-80% of area median income for 99 years. Construction began April 1, 2025; the Village projected 22-24 months of construction followed by two to three months of lease-up, targeting mid-2027 completion. The project includes approximately 3,400 square feet of ground-floor commercial space. (HCR announcement; Village QA page)

Crescent Manor at 136-140 Croton Avenue is under construction with 74 units of affordable senior rental housing restricted to households age 62 and older. Groundbreaking occurred May 22, 2025; no current official completion date was found. The project includes up to 3,500 square feet of retail or community space. (Village planning page; News12 coverage)

The 34 State Street redevelopment, including 17 and 21 James Street, proposes 150 units: 100 affordable homeownership units and 50 market-rate rental units. A bedroom mix was not published in the records reviewed. The project remains under review; Zoning Board and Historic Preservation approvals were granted in June 2026, but the Planned Waterfront Special Permit and site-plan and conditional-use review remained pending. (Village document 165303; Village document 163682)

A mixed-use building at 209-211 Main Street proposes 16 units: seven one-bedroom and nine two-bedroom. The application includes a 10% affordable-housing set-aside, but tenure was not specified. This project also remains under review. (Village document 160270; Village document 161782)

Zoning changes

Local Law 7-2025, adopted November 5, 2025, established an eight-month moratorium on new conditional-use applications in the Village of Ossining T (Two-Family Residence) District. The moratorium temporarily stopped applications for uses including educational facilities, senior living, cemeteries, nonaccessory parking, places of worship, and major home occupations. The law authorized an extension of up to four months, but no adopted extension was located. The law does not quantify an enrollment or tax-base effect. (Ecode360)

The 34 State Street project requires height, story, and minimum-livable-floor-area variances and a Planned Waterfront Special Permit to enable the current 150-unit proposal. No official student-generation or tax-base amount was published. (Village ZBA presentation)

Commercial tax base additions and risks

The Ossining Energy Storage 1 LLC project at 381 North Highland Avenue is a 4 MW/16 MWh battery energy-storage facility with a projected assessed value of $6 million in the original application. The IDA project agreement requires completion by November 29, 2026. (Project agreement)

The district faces a reported $6.7 million in potential tax-certiorari exposure, according to Citizen Portal. A June 10, 2026 district public hearing on establishing a tax-certiorari reserve is confirmed by the district's board records. The amount is reported by one secondary source and was not independently recoverable from the official text reviewed. (Citizen Portal; district board records)

PILOTs and abatements diverting school revenue

Five tax instruments affect school-district revenue from recent development projects.

The Station Plaza PILOT is a 30-year partial real-property-tax abatement. The Village states that the school district will receive a share intended to offset costs from additional students and that the publicly owned site previously generated no property tax. Neither the final annual schedule nor the school-district allocation was published. (Village QA; IDA meeting packet) A separate Station Plaza IDA sales-and-use-tax exemption is capped at $2,427,243; this is not a school property-tax payment and does not represent a direct diversion of school revenue. (IDA meeting packet)

The Crescent Manor PILOT application described a long-term payment of approximately $1,000 per unit. The IDA cost-benefit analysis estimated $5,382,643 in net-present-value real-property-tax exemptions across affected taxing jurisdictions but did not isolate an annual Ossining school-district share. (IDA application; IDA cost-benefit summary)

The Ossining Energy Storage 1 LLC project retained a sales-and-use-tax exemption capped at $838,771.24 in its final IDA request; the requested PILOT and mortgage-recording-tax exemption were dropped. The exemption expires December 31, 2034 under the project agreement, extendable to December 31, 2037 for unavoidable delay. (Updated IDA application; project agreement) Separately, the application states that the battery project is eligible for a 15-year New York Real Property Tax Law section 487 exemption and that the church-owned site generated $0 in property tax at application. No incremental school-district effect was quantified. (IDA application)

School facilities bond

The district reports secondary classroom utilization of 100%-107%. A $210 million facilities bond program was approved by voters on September 24, 2024, with broad construction activity scheduled for summer 2026. The bond adds a grades 7-8 building, a three-story Ossining High School classroom addition, STEAM/STEM and music rooms, expanded lunch space, and classroom and support space in a renovated former church. (district facilities page) At Brookside School, an addition under construction as of June 24, 2026 adds nine classrooms and support spaces plus a new elevator and driveway. At Anne M. Dorner Middle School, a new entrance road from Stormytown Road and cooling-system work were underway as of the same date. (district construction update)

The choice ecosystem

Ossining Union Free School District operates within a choice landscape that includes district-run themed programs, nearby private and parochial schools, and state-regulated home instruction. No charter schools operate within the district's boundaries. Under New York law, charter school applications are authorized by the Board of Regents or the SUNY Board of Trustees, and local school boards may consider charter conversions. No charter authorization or conversion activity is documented for Ossining in the available research.

The district's principal themed offering is its Spanish-English dual-language sequence, which spans five buildings across grade levels. The pathway begins at Park Early Childhood Center for Pre-K and kindergarten, continues at Brookside School for grades 1 and 2, moves to Claremont School for grades 3 and 4, transitions to Roosevelt School for grade 5, and extends to Anne M. Dorner Middle School for a grade 6 continuation. Dual-language seats at entry points are limited and assigned by lottery within registration windows. The district does not publish the number of available seats or a waitlist policy for this program, so families cannot determine from public materials how likely a lottery entry is to result in placement.

Several private and parochial schools serve families in the broader region. The district provides transportation to eligible students attending nonpublic and parochial schools, with eligibility for the 2026-27 year requiring that the child be age 5 by December 1, 2026 and that the school be within 15 miles of the family's home.

St. Augustine School, a Pre-K through grade 8 Roman Catholic school, publishes 2026-27 tuition at $4,750 for morning Pre-K, $6,850 for a hybrid Pre-K schedule, and $8,080 for full-day Pre-K. For kindergarten through grade 8, one-child tuition is $7,365 for qualifying St. Augustine parishioners or $10,850 for non-Roman-Catholic parishioners, with additional fees. The Leffell School, a K-12 Jewish day school, publishes 2026-27 tuition ranging from $35,900 for kindergarten to $51,900 for grades 9 through 12, with intermediate rates at each grade band. Hackley School, a K-12 independent school, lists 2026-27 day tuition from $52,880 for grades K-4 to $61,895 for grades 9-12, with optional five-day boarding adding $18,905. Rye Country Day School, serving Pre-K through grade 12, publishes 2026-27 tuition from $53,210 for Pre-K through grade 4 to $59,070 for grades 9-12, with lunch included in the published rate.

New York State does not administer a voucher or education savings account program. A federal scholarship tax credit program has been reported with New York opting in, with the program described as beginning January 1, 2027. No Ossining UFSD participation or local fiscal effect has been published as of July 2026, and local uptake is not evidenced in available district materials.

Home instruction is regulated by the New York State Education Department, which maintains published policies and procedures for families electing to homeschool. The district does not separately publish the number of Ossining residents pursuing home instruction or microschool arrangements.

Programs, logistics, and special populations

Special education

According to NYSED data for 2024-25, 698 students with disabilities were identified in the district, representing 15% of enrollment. The district's special education model follows a continuum that begins with general education supplemented by related services and extends through Resource Room support, Integrated Co-Teaching (ICT) classrooms where a general education teacher and a special education teacher co-instruct, and self-contained special classes grouped by student needs. The district also operates a program identified as RISE, though its published materials do not detail the specific population or grade range it serves. Related services available include occupational therapy, physical therapy, and speech/language therapy. The district does not publish placement breakdowns showing how many students receive services at each point along the continuum, so the distribution of students across these settings is not publicly visible.

English learners and dual language

NYSED reports 1,096 English learners for 2024-25, approximately 23% of total enrollment. The district offers K-12 Integrated English as a New Language (ENL), in which language support is embedded within content-area instruction, and K-12 Standalone ENL, which provides dedicated language acquisition periods. The district operates both two-way and one-way Spanish-English dual-language models. In a two-way model, classrooms mix native Spanish speakers and native English speakers, with instruction delivered in both languages to develop bilingualism in both groups. In a one-way model, the program serves students from a single language background. The dual-language sequence spans Park Early Childhood Center for Pre-K and kindergarten, Brookside School for grades 1-2, Claremont School for grades 3-4, Roosevelt School for grade 5, and Anne M. Dorner Middle School for grade 6 continuation. World language offerings include Spanish, French, Italian, and American Sign Language, and students may pursue the New York State Seal of Biliteracy.

Pre-kindergarten

The district operates a universal pre-kindergarten model, offering free, full-day UPK for resident 4-year-olds. Programming is located at Park Early Childhood Center and at a district-partner classroom at the Ossining Children's Center at 32 State Street. The district does not publish seat capacity figures or a waitlist policy for UPK on its cited registration pages, so families cannot determine from public materials whether demand exceeds supply or whether all applicants receive seats.

Career and technical education

Ossining participates in three P-TECH (Pathways in Technology Early College High School) pathways, each structured as a multi-year program combining high school coursework, college credit, and industry exposure. The P-TECH Health Information Technology pathway partners with Westchester Community College, Sun River Health Center, Open Door Family Medical, Peekskill Volunteer Ambulance Corps, Ossining Volunteer Ambulance Corps, PNW BOCES, and Peekskill City School District. The P-TECH Paramedic pathway partners with Westchester Community College, Peekskill Volunteer Ambulance Corps, Ossining Volunteer Ambulance Corps, PNW BOCES, and Peekskill City School District. The P-TECH Computer Information Technology and Cybersecurity pathways partner with Westchester Community College, PNW BOCES, and Peekskill City School District. All three P-TECH pathways lead to a New York high school diploma and a no-cost associate degree from Westchester Community College. The district also offers BOCES programs through the PNW BOCES Tech Center, including New Visions Health, Sports Medicine and Veterinary Science, which provides high-school academic credit, and trade-focused and senior four-hour CTE options that may yield Career Development and Occupational Studies (CDOS) credential eligibility and high-school credit.

Athletics and arts

The district's athletic offerings include bowling, gymnastics, ice hockey, girls flag football, field hockey, and cheerleading, in addition to other sports programs. In the arts, the district maintains band, orchestra, and chorus programs with additional ensembles and musical theater. Course offerings extend to film, photography, jewelry, fashion, and music production and technology.

Transportation, care, and calendar

For transportation to nonpublic and parochial schools in 2026-27, eligibility requires that the child be age 5 by December 1, 2026 and that the school be within 15 miles of the family's home. The district does not publish separate bus eligibility thresholds for public school students on its cited transportation page, nor does it publish bell times in the available materials. The absence of published bell times means families cannot verify start and end times for individual schools from district sources alone.

Before and after school care is provided through the Ossining Children's Center, a community-based provider. The center advertises after-school programming for ages 5 to 13 with bussing to and from Ossining public schools and operating hours spanning 7:00 a.m. to 6:00 p.m. School-age rates are not posted on the center's cited pages, though the center notes tuition-based wraparound care beyond the free UPK core day. No capacity or waitlist details are published, so families cannot confirm availability from public materials alone.

The district's class-size guidelines, which the district describes as submitted guidelines rather than contractual caps, set target ranges of 18-20 for kindergarten, 20-22 for grade 1, 22-24 for grades 2-3, 24-26 for grades 4-5, and 25-28 for secondary grades. These are administrative targets, not enforceable maximums.

The 2026-27 calendar sets the first student day as September 2, 2026 and the last student day as June 25, 2027.

Safety, climate, and community

The district's safety and discipline picture comes from two distinct reporting systems, each with its own definitions, scope, and limitations. Understanding what each system counts is necessary before interpreting any figure, because raw counts without context can mislead.

Official incident reporting

New York State requires districts to report incidents through the School Safety and Educational Climate (SSEC) system. The NYSED SSEC incident data for 2024-2025 is published in a Rest of State workbook. The SSEC counts violent or disruptive incidents occurring July 1 through June 30 on school property, buses, and at school functions, including reports filed under the Dignity for All Students Act (DASA). The state's category definitions note that definitions and categories have been revised in recent years, so raw counts are not comparable across reporting periods without the applicable definitions for each year. This means a change in reported incidents from one year to the next may reflect a definitional shift rather than a change in actual safety conditions. The 2024-2025 Rest of State workbook is the latest available reporting period.

Federal discipline data

The US Department of Education's Civil Rights Data Collection (CRDC) for the 2021-22 school year provides a different lens, focusing on disciplinary actions taken against students without disabilities rather than on incident types. The CRDC distinguishes among three categories: in-school suspensions, which remove a student from the regular classroom but keep them in the school building; single out-of-school suspensions, which remove a student from school for one disciplinary episode; and multiple out-of-school suspensions, which indicate a student was suspended out of school more than once during the reporting year.

In 2021-22, across the district's six schools, the CRDC recorded 50 in-school suspensions of students without disabilities, 116 single out-of-school suspensions, and 31 multiple out-of-school suspensions. These figures are disaggregated by race and sex. Among students without disabilities receiving in-school suspensions that year, 28 were Hispanic/Latino, 12 were Black/African American, 6 were White, and 3 were of two or more races. For single out-of-school suspensions, 68 were Hispanic/Latino, 24 were Black/African American, 8 were White, 4 were of two or more races, and 2 were Asian. For multiple out-of-school suspensions, 15 were Hispanic/Latino, 10 were Black/African American, 1 was White, and 2 were of two or more races. The CRDC also tracks English Learners as an overlapping category, meaning these students are also counted within a racial category. In 2021-22, 1 English Learner received an in-school suspension, 10 received single out-of-school suspensions, and 3 received multiple out-of-school suspensions. The CRDC data does not include students with disabilities, who are tracked under a separate reporting category not provided in the available dataset.

Discipline approach and school resource officers

The district's Code of Conduct, adopted on September 17, 2025, sets what the district describes as a developmentally responsive, progressive discipline approach. The code references Multi-Tiered Systems of Support (MTSS) and restorative practices aimed at repairing harm and reintegrating students. MTSS is a framework that provides increasing levels of academic and behavioral support based on student need, typically structured in tiers where Tier 1 is universal support for all students, Tier 2 adds targeted intervention for students identified as needing more, and Tier 3 provides intensive individualized support. Restorative practices, in this context, refer to structured processes in which affected parties engage in dialogue about an incident's impact and agree on steps to repair harm, rather than relying solely on exclusionary discipline.

Regarding school resource officers, the district's 2026-2027 District-Wide Safety and Emergency Management Plan includes a section titled "Private Security and School Resource Officers." The accessible public draft of that plan did not specify whether a school resource officer is currently assigned to the district or whether any recent change in SRO status has occurred. The absence of a specific assignment statement in the public document means the current SRO status cannot be confirmed from available materials.

Cell phone and device policy

New York enacted a statewide distraction-free schools requirement directing districts to adopt and publish bell-to-bell personal device restrictions for the 2025-2026 school year. Under this mandate, districts were required to select local storage solutions, ensure parent-to-student contact channels, and define enumerated exceptions for circumstances such as medical needs.

Ossining implemented its policy through Policy 5695 in summer 2025. The policy prohibits student use of internet-enabled devices during the school day, establishes storage requirements, and enumerates specific exceptions. The district directs families to use school channels to reach students rather than contacting them directly on personal devices during instructional hours.

Climate surveys

District materials state that the Panorama School Climate Survey is used to gather student and staff feedback on safety, belonging, and educator wellness. No dated, district-level survey result was publicly posted as of the most recent review. The absence of published results means the survey's findings, if collected, are not available for public examination through standard district communications.

Governance context

The district's Board of Education approved a contract extension for Superintendent Mary Fox-Alter through the 2026-27 school year, as reported by lohud in December 2024. The extension was also covered by River Journal and Patch. No public controversy over the extension was documented in the available reporting.

Leadership, governance, and labor

The Ossining Union Free School District is governed by a seven-member Board of Education and administered by a superintendent whose cabinet includes assistant superintendents for curriculum and instruction, pupil personnel services, business, and human resources, along with directors for literacy, mental and behavioral health, school counseling, student support services at both elementary and secondary levels, facilities, and STEM. The district serves approximately 4,993 students as of the 2023-24 school year.

Superintendent

Mary Fox-Alter serves as Superintendent of Schools. She joined the district as interim superintendent in July 2023, following the resignation of her predecessor, Raymond Sanchez. Her background includes 11 years as superintendent of Pleasantville UFSD and service as a New York State-appointed academic monitor in East Ramapo, a district that was under state intervention. In December 2024, regional outlets reported that the Board unanimously appointed Fox-Alter as the non-interim superintendent through June 30, 2027. Patch and the River Journal also reported the appointment. The research notes that a board resolution or contract document was not captured in the source sweep, so the specific terms, including an annual salary of $320,000 with a 3% tax-deferred annual increase, are drawn from the district's reported figures and media accounts rather than a verified board document on file.

Superintendent turnover across the last decade

Over the past decade, the district has had at least two superintendents. Raymond Sanchez served as superintendent before resigning in 2023 to accept a superintendent position in the Tarrytown school district, as reported by LoHud in May 2023. Fox-Alter began as interim in July 2023 and was appointed to the permanent role in late 2024, creating an interim period of approximately 17 months. The available research identifies one named predecessor (Sanchez) with a confirmed resignation. The exact start date of Sanchez's tenure and any superintendents who may have served prior to him within the decade are not specified in the data on file. The AASA maintains a profile page for Sanchez, but its contents were not captured in this research sweep. Superintendent turnover is a leading indicator of organizational stability, and the single transition documented here involved a structured interim-to-permanent pathway rather than an abrupt departure.

Board of Education

The Board of Education comprises seven members. Christine Mangiamele serves as President with a term expiring in 2028. Roger Battacharia serves as Vice President with a term expiring in 2027. Melissa Banta serves as Trustee with a term expiring in 2028. The remaining trustees are Katherin Crossling, Quratul (Annie) Akhtar-Gomez, Robert Melstein, and Frank Schnecker. Term expiration dates for Crossling, Akhtar-Gomez, Melstein, and Schnecker are not individually specified in the available data, though the election records below provide context for when they were seated. Board member information and trustee biographies are published on the district's website, and meeting schedules are available through the board meetings page. The Board also maintains a public meeting portal through BoardDocs for agendas and minutes.

Recent board elections

The district has held annual board elections in May, with several contests drawing multiple candidates:

• May 19, 2026: A contested election for three seats. Frank Schnecker received 754 votes, Robert Melstein received 741 votes, and Quratul (Annie) Akhtar-Gomez prevailed over Renee Nelson, who received 652 votes. This election coincided with the 2026-2027 budget vote, which regional outlets reported as passed.
• May 20, 2025: Two seats filled without contest. Official results were posted by the district.
• May 21, 2024: Two seats filled, with results certified in the official election minutes.
• May 16, 2023: A contested election for three seats, with results certified in the official minutes.
• May 17, 2022: A contested election for two seats, with results certified in the official minutes.

Turnout figures beyond the 2026 vote counts are not published in the available research. The 2026 election is the only cycle in the dataset with specific vote tallies. Press releases and minutes for the 2025-2026 cycle are available on the district's board page.

Bargaining units and contracts

The Ossining Teachers Association (OTA) represents approximately 500 members. The current collective bargaining agreement runs from July 1, 2025 through June 30, 2029, as posted by the OTA. No other bargaining units are identified in the available research. No work stoppages, strikes, or labor disruptions are documented in the data on file. The absence of documented work stoppage history does not constitute a finding that none has occurred; it indicates that none was captured in this research sweep.

State oversight and fiscal stress

No current state monitor or fiscal-stress designation has been identified for the district. The New York State Education Department's state monitors page does not list Ossining among districts under active monitoring. In October 2017, the Office of the New York State Comptroller conducted an audit of Ossining UFSD's financial management (Report 2017M-176). The audit report identified findings that required corrective action. This was an audit, not a monitor appointment or fiscal-stress designation. The OSC also publishes a broader fiscal stress monitoring document for schools that provides context for how the state evaluates district fiscal health, but no current designation for Ossining appears in the available research.

Governance conflict signals

The available research does not document specific governance conflicts, board-superintendent disputes, formal no-confidence votes, or other documented signals of governance dysfunction. The contested board elections in 2022, 2023, and 2026 indicate competitive races for seats, but competitive elections are a routine feature of district governance and do not, by themselves, signal conflict. No findings of governance instability are present in the data on file.

Material litigation

No material litigation involving the district is identified in the available research. The absence of litigation reporting in the sourced material does not constitute a finding that no litigation exists; it indicates that none was captured in this research sweep. Pending allegations, if any exist, are not documented in the available data and therefore cannot be labeled as pending or otherwise characterized here.

Risks and watch items: the forward calendar

The following items represent scheduled facts with known dates or expected windows. Each is drawn from the sourced research and represents a point in time when a decision, expiration, or public event is expected to occur. No predictions are made about outcomes.

Contract expirations

• Superintendent Mary Fox-Alter's contract expires June 30, 2027. The contract, reported by regional outlets in December 2024, carries an annual salary of $320,000 with a 3% tax-deferred annual increase. The district will face a decision point on renewal, extension, or succession before this date. No public discussion of a successor or extension has been documented in the available research.

• The Ossining Teachers Association collective bargaining agreement expires June 30, 2029. The contract terms are posted by the OTA. The agreement covers approximately 500 members and runs from July 1, 2025 through its expiration date. Negotiations for a successor agreement would typically begin in the year preceding expiration, though no negotiation timeline is published in the available research.

Board elections and terms

• Roger Battacharia's term as Vice President and trustee expires in 2027. The annual school board election cycle in New York State typically places votes in May, meaning the 2027 board election would occur on a date in May 2027 that has not yet been set. The district's calendars page and board meeting schedule are the appropriate sources for confirmed dates once published.

• Christine Mangiamele's term as President and trustee expires in 2028, as does Melissa Banta's term. The May 2028 election date is not yet scheduled.

• The district has held contested board elections in three of the last five cycles (2022, 2023, and 2026). Future elections may draw multiple candidates, though this is observation of past patterns, not a prediction.

Annual budget cycle

• The district's annual budget vote occurs each May, as established by New York State education law. The 2026-2027 budget was reported as passed on May 19, 2026. Budget materials for the current cycle are published on the district's website. The next budget vote is expected in May 2027, though the specific date is not yet set.

Facilities bond program

• Voters approved a major facilities bond program on September 24, 2024. The work includes a new grades 7-8 building, high-school STEAM/STEM and music spaces, lunchroom expansion, and reuse of former church property. The district's facilities page provides information on the program. Construction timelines and specific project milestones are not detailed in the available research. Families should monitor the district's news page for updates on construction phases, potential disruptions to school operations, and completion dates.

Safety plan updates

• The district posted its updated 2026-2027 District-Wide Safety and Emergency Management Plan with an approval date in late spring 2026. The plan covers command structure, reporting protocols, building security, early detection systems, and coordination with law enforcement. An internal date inconsistency was noted in the research. The safety plan is updated annually, meaning the next revision would be expected in spring 2027, though the specific date is not yet scheduled. The district's student support services page and the NYSED school safety page provide additional context.

Policy implementation monitoring

• The district adopted Policy 5695 on July 30, 2025, implementing New York's bell-to-bell restriction on student use of internet-enabled devices. The district's device policy page outlines storage requirements and defined exceptions. Implementation is ongoing, and the 2025-26 school year represents the first full year of operation under this policy. Any adjustments based on implementation experience would be expected to appear in board materials, though no revision date is scheduled.

• The updated Code of Conduct, adopted September 17, 2025, emphasizes progressive discipline, multi-tiered systems of support, and restorative practices. The code is published on the district's website. As a newly adopted framework, its implementation and any subsequent revisions warrant monitoring through board meeting materials.

Items not yet scheduled

• No court dates, study milestones, or state intervention reviews are identified in the available research. The 2017 Comptroller audit required corrective action, but no follow-up audit or review date is published in the sourced material. The absence of a scheduled follow-up does not indicate one will not occur; it indicates none is documented in this research sweep. The NYSED and OSC websites are the appropriate sources for any future fiscal stress designations or audit announcements.

Surprising insights

Several findings in this report run counter to what a resident might assume about how the district operates.

The grade-center model eliminates neighborhood school assignment. Ossining does not use neighborhood attendance zones for elementary school. Every child in a given grade across the entire district attends the same building, following a fixed sequence: Park School for pre-K and kindergarten, Brookside for grades 1 and 2, Claremont for grades 3 and 4, Roosevelt for grade 5, Anne M. Dorner Middle School for grades 6 through 8, and Ossining High School for grades 9 through 12. A family comparing two homes on different streets need not ask which elementary school each feeds to, because both feed to the same school. The only question is whether the grade-center sequence itself remains stable, not which building a particular address is assigned to (source).

Nominal tax rates vary by a factor of 56 across the district's three towns, but tax bills for comparable homes do not. The 2025-26 tax rate per $1,000 of assessed value was $19.008 in the Town of Ossining, $135.097 in the Town of New Castle, and $1,073.916 in the Town of Yorktown, according to Westchester County tax rate data. These figures are not comparable at face value because each town assesses property at a different fraction of market value. Yorktown's assessments are a much lower fraction, requiring a higher rate to produce comparable revenue. A parent who sees the Yorktown rate and assumes it means higher school taxes would be mistaken; the equalization process adjusts for these differences so that properties of equal market value contribute proportionally to the district levy (source).

The district's unassigned fund balance dropped by more than half between 2021 and 2022 and has not recovered. The balance fell from $14,828,841 (12.22% of expenditures) in 2021 to $6,061,594 (4.63%) in 2022, according to the New York State Office of the State Comptroller. It has since recovered modestly to $7,146,692 (4.52%) by 2025, but remains well below the 2021 level. This decline coincides with the period of federal pandemic relief deployment and represents a structural shift in the district's financial cushion that persists four years later (source).

AP Calculus AB has a lower proficiency rate than AP Calculus BC, despite BC being the more advanced course. In 2023-24, 16.0% of 12th-grade Calculus AB test-takers achieved proficiency, compared to 52.4% of 12th-grade Calculus BC test-takers. This is not a contradiction: the two exams are taken by different student populations, and the students who reach Calculus BC are a self-selected subset who have typically completed Calculus AB first. The proficiency rate reflects who takes each exam, not the difficulty of the material relative to the test-taker.

The district has one high school, so every district-level high school metric is a single-school metric. There is no spread between high schools to analyze, no comparison to make. When the district reports an AP proficiency rate, it is Ossining High School's rate. This structural fact means that variation in high school outcomes can only be examined within the school, across subjects and grade levels, not between schools.

Best fit: who this district serves well

Fit is a function of educational and logistical needs, not of who a family is. The following describes what this district's structure and programs accommodate, and what they do not.

A family seeking a predictable, single-pathway PK-12 progression

Ossining's grade-center model means that every resident student in a given grade attends the same building, and the sequence is fixed. There are no competing elementary attendance zones, no choice between middle schools, and no choice between high schools. This structure directly addresses the need for predictability in school assignment: a family knows exactly which building their child will attend at each grade level without uncertainty about boundary lines or feeder patterns. The trade-off is that there is no alternative building within the district if a family is dissatisfied with a particular school's performance, culture, or approach. The district's self-contained PK-12 system also means a student can complete the entire progression without transferring to an outside district for any grade level.

A student interested in science research with university credit potential

The Fundamentals of Science Research program at Ossining High School offers a selective sequence through which students can earn up to 12 University at Albany credits via dual enrollment. This represents the highest documented academic ceiling in the district. A student who is prepared for the selective admissions process and wants to accumulate transferable State University of New York credit while in high school has a documented pathway here. The selective nature of the program means that not all students who want to participate will be admitted, and the specific entry criteria are not published in the sources available to this report (source).

A student seeking AP course breadth

The district offers AP courses across multiple subjects, including Biology, Calculus AB, Calculus BC, Computer Science A, Environmental Science, Language and Composition, and Chemistry, based on the 2023-24 assessment data. A student who wants to take AP exams in several subjects has options. The proficiency rates vary substantially across subjects, from 16.0% in 12th-grade Calculus AB to 80.0% in 12th-grade Biology, so a student's experience will depend on which courses they take and how they are prepared for each exam (source).

A family interested in Dual Language education

The district offers a Dual Language program with entry points in kindergarten and grade 1. However, seats are limited and selection is by lottery for the 2026-27 school year. The district does not publish seat counts, selection odds, waitlist information, or sibling priority. A family that needs Dual Language placement faces uncertainty that does not exist in the standard grade-center track, and there is no guaranteed access.

What the district does not currently offer

No International Baccalaureate program is documented in the available sources. The district does not offer a choice between multiple high schools or multiple middle schools. School-level assessment results for elementary and middle school buildings are not available in the data on file, so a family cannot compare measured outcomes across buildings within the district. The district reports secondary classroom utilization at 100 to 107 percent, with capacity strain at Anne M. Dorner Middle School and Ossining High School, and has proposed a bond to construct a new grades 7-8 school to address this pressure (source). A family needing extensive special education services, English learner support, or other specialized programming should consult the district directly, because the available data does not include Individualized Education Program counts, English learner counts, or building-level service information. The chronic absenteeism rate of 14.9% in 2022-23 indicates that a meaningful portion of students miss 10% or more of enrolled school days, which families may want to discuss with building administrators.

Questions parents should ask

1. What is the construction timeline for the bond-funded grades 7-8 school on the former church property, and will my child's middle school placement be affected during the transition? This matters because the district reports 100 to 107 percent secondary utilization and has proposed a new building, but construction timelines affect current students. Ask the district facilities office or board of education.

2. How many Dual Language kindergarten and grade-1 seats are available for 2026-27, and what are the selection odds in the lottery? This matters because the program is lottery-based with limited seats and no published counts or odds. Ask the district's English as a New Language department.

3. What criteria determine placement in accelerated middle school mathematics, specifically for Algebra I in grade 8? This matters because the Civil Rights Data Collection collected Algebra I data but the placement mechanics are not documented in available sources. Ask the Anne M. Dorner Middle School counseling department.

4. How does the district identify students for gifted and talented services, and what assessments or referrals are used? This matters because the CRDC collected gifted enrollment data but identification methods are not published in available sources. Ask the district curriculum office.

5. What is the district's plan for absorbing the cost of previously ESSER-funded programs after the three-year transition ends? This matters because the 2026-27 budget uses $10,160,303 in appropriated fund balance and reserves to close the gap, and the transition's endpoint is not fully specified in available materials. Ask the business department or superintendent's office.

6. For a property in the Briarcliff Manor area, how can I confirm whether it falls within Ossining UFSD or Briarcliff Manor UFSD? This matters because municipal boundaries and school district boundaries do not coincide, and a Briarcliff Manor address does not determine school assignment. Ask the district registration office.

7. What is the current utilization rate of each elementary building, and are any approaching capacity constraints? This matters because the district reports secondary strain but does not publish building-by-building elementary utilization in available materials. Ask the facilities department.

8. How does the science research program's selective admissions process work, and what are the entry criteria? This matters because the program offers up to 12 university credits but the selection process is not detailed in available sources. Ask the Ossining High School science research department.

9. Are all students enrolled in AP courses expected to sit for the corresponding exams, and how does this affect the proficiency rate denominator? This matters because proficiency rates reflect only exam-takers, not all enrolled students, and the participation rate is not reported. Ask the high school counseling department.

10. What specific non-contingent expenditures would be suspended if the budget were defeated and a contingency budget adopted? This matters because the contingency budget mechanism eliminates discretionary spending and freezes the tax levy at the prior year's level with no inflation factor. Ask the superintendent's office or board of education.

Scope, method, and sourcing notes

This report describes the Ossining Union Free School District using computed data from government sources and acquired research from district and state publications. The report does not rate, rank, or recommend the district. Every figure is attributed to its source, and where data is missing, that absence is stated plainly rather than estimated or imputed.

Enrollment and demographics. Enrollment of 4,993 students for 2023-24 comes from the NCES Common Core of Data. Race and ethnicity counts and rates are reported for the same year. 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. No long-run enrollment series was available; the report presents a single-year snapshot.

Academic outcomes. Advanced Placement proficiency rates for 2023-24 come from New York state assessment records processed through the profile corpus. The data encompasses 52 series spanning 2006 through 2025, but the specific data points available are from 2023-24. No New York State Regents exam results, grades 3-8 state assessment results, college enrollment or completion data, or social-emotional outcome measures are included. Subgroup breakdowns by race, ethnicity, economic status, English learner status, or disability status are not available in the AP proficiency data. State assessment testing was cancelled in 2020 due to the COVID-19 pandemic, creating a gap in the longitudinal record.

Graduation. The most recent graduation data on file is from the 2019-20 school year, sourced from EDFacts ACGR via the Urban Institute Education Data API. The cohort size was 352 students. No graduation rate percentage is provided in the computed data. This data is several years old and reflects a cohort that was in its final year during the onset of the pandemic. It should not be treated as indicative of current graduation outcomes.

Chronic absenteeism. The chronic absenteeism rate of 14.9% is from the 2022-2023 school year, sourced from EDFacts Data Group 814.

Civil Rights Data Collection. AP enrollment, Algebra I enrollment, gifted and talented enrollment, and suspension data come from the CRDC for SY2021-22. Specific counts for eighth-grade Algebra I placement and gifted identification methods are not available in the data provided.

Finance. Per-pupil spending, revenue mix, and expenditure data come from the U.S. Census Bureau Annual Survey of School System Finances (F-33) for FY2023. Fund balance data comes from the New York State Office of the State Comptroller. Debt and bond information comes from district budget materials and fiscal advisor presentations. Adopted budget figures come from the district's own published budget documents.

Limitations. Market figures, if referenced, are ZIP-level approximations and not property-specific. Child poverty data was unavailable. School-level assessment results are not available in the computed data; the assessment series are aggregated to the district level. No independent capacity utilization audit was identified in the available materials; capacity figures are self-reported by the district. The district's boundary descriptions are based on the district's own website and have not been verified against official boundary surveys.

About SchoolDecision.com

SchoolDecision.com publishes source-attributed profiles of U.S. school districts and schools built from government data and official district publications. It does not rate, rank, or recommend districts. Every figure is traced to its originating source, and missing data is reported as missing rather than estimated or imputed. The publication is designed for families and households evaluating school district boundaries as part of a housing decision, and it describes what is true so that readers can decide for themselves.
