Summary Perspective

Ardsley Union Free School District is a small-scale, single-feeder K-12 system whose defining structural feature is its simplicity. With 2,324 students enrolled in the 2023-24 school year across three schools, according to the National Center for Education Statistics, the district operates one elementary school, one middle school, and one high school. This one-school-per-level design means that every resident student follows the same path: Concord Road Elementary to Ardsley Middle to Ardsley High. There are no internal attendance lines, no feeder pattern uncertainty, and no same-grade school choice. The only boundary that determines assignment is the district boundary itself, which can be altered only through a formal legal process under New York Education Law Sections 1507 and 1508, administered by the Commissioner of Education.

The district's headline academic data is concentrated at the Advanced Placement level. For the 2023-24 school year, AP proficiency rates ranged from 69.2 percent in AP Calculus AB for grade 12 to 100 percent in AP Biology for grade 12, AP Calculus BC for grade 12, and AP Comparative Government and Politics for grade 12. AP Chemistry showed a 91.7 percent proficiency rate for grade 11, and AP Biology showed 95.5 percent for grade 11. The four-year adjusted cohort graduation rate from 2019-20, the most recent on file, was reported as a suppressed range of 95 to 100 percent based on a cohort of 162 students. Chronic absenteeism for 2022-23 was 9.4 percent. The district's schools are designated under the Local Support and Improvement model for the 2025-26 accountability cycle, which is the baseline tier of New York's accountability framework, below which more intensive support tiers such as Comprehensive Support and Improvement and Targeted Support and Improvement apply.

The single most decision-relevant contextual fact for a family evaluating this district is the one-school-per-level structure. In a district where residence anywhere within the boundary maps to the same three-school sequence, the question of which school a child will attend is answered entirely by grade level. There is no variation between schools at the same level to investigate, because there is only one school at each level. The variation that exists is programmatic, concerning which courses a student selects at the high school level, rather than spatial, as it would be in a district with multiple elementary or middle schools feeding into a shared high school. A family evaluating this district should focus on the academic program within the high school and on the district's fiscal and facilities trajectory rather than on school assignment risk.

The district is undertaking a $50 million capital improvement project, indicating investment in its physical plant, though no published capacity utilization study was identified in the materials reviewed. The property tax levy is subject to New York's tax cap under Education Law Section 2023-a, which limits annual levy growth unless overridden by a supermajority of voters. The district's boundaries encompass territory in multiple municipalities within Westchester County, including the village of Ardsley in its entirety, the village of Dobbs Ferry in part, and the town of Greenburgh in part, meaning that a property's municipal address alone does not determine school district assignment.

This report describes what is true about the district as of the available data. It does not rate, rank, or recommend the district, nor does it advise any family to choose or avoid it. The evidence on file includes gaps and limitations, particularly the absence of Regents exam results, grades 3-8 state assessment data, and current graduation figures, and these gaps are identified where they occur so that families can weigh the available information accordingly.

Key takeaways for families

  • The district operates one school at each level, meaning all resident students attend the same elementary, middle, and high school regardless of where they live within the district boundary. There are no internal attendance lines to redraw and no same-grade school choice to navigate.

  • No active boundary study, redistricting process, or school closure plan was found as of a review conducted through July 2026. The one-school-per-level structure means the only boundary that matters is the district boundary itself, which is fixed by geography and state-level legal processes.

  • AP proficiency rates for 2023-24 varied substantially by subject, from 69.2 percent in AP Calculus AB for grade 12 to 100 percent in AP Biology, AP Calculus BC, and AP Comparative Government and Politics for grade 12. The available assessment data covers only AP exams and does not include Regents exam results or grades 3-8 state assessments.

  • The graduation rate from 2019-20, the most recent data on file, was 95 to 100 percent for a cohort of 162 students. This data is several years old and predates the full effects of pandemic-era disruptions on subsequent graduation cohorts.

  • Chronic absenteeism for 2022-23 was 9.4 percent, meaning that approximately 9.4 percent of students missed 10 percent or more of enrolled school days, whether excused or unexcused.

  • The district is undertaking a $50 million capital improvement project. Capital investment of this scale indicates facilities maintenance and upgrading but does not by itself indicate whether enrollment is growing, declining, or stable relative to building capacity.

  • The district does not publish a building-by-building capacity utilization study. Without this benchmark, it is not possible to determine from available data whether any individual school is approaching its functional capacity limit.

  • The property tax levy is subject to New York's tax cap under Education Law Section 2023-a, which limits annual levy growth. If voters defeat the proposed budget at the May election, the district must adopt a contingency budget that caps the levy at the prior year's level, or resubmit a revised budget for a second vote.

  • The district's boundaries encompass territory in multiple municipalities, including the village of Ardsley in its entirety, the village of Dobbs Ferry in part, and the town of Greenburgh in part. A property's municipal address does not by itself determine school district assignment, and families should verify district assignment for any given property.

  • The district boundary can only be changed through a formal legal process under New York Education Law Sections 1507 and 1508, administered by the Commissioner of Education. A municipal boundary change such as a village annexation does not by itself move school district lines.

  • The Board of Education consists of five members elected to three-year terms at large, with elections held concurrently with the annual budget vote in May. The next scheduled board election is May 18, 2027.

  • The district offers Advanced Placement courses, Syracuse University Project Advance dual-enrollment courses, and a Science Research Program at the high school level. No International Baccalaureate program is described in available materials.

The table above is intended as a quick reference. Each row corresponds to a topic discussed in greater detail in the body sections of this report, and readers should consult those sections for context, methodology notes, and caveats that a summary table cannot capture. In particular, the graduation rate from 2019-20 is several years old, the AP proficiency data reflects only the subset of students who took AP exams, and the absence of Regents and grades 3-8 assessment data means the academic picture is weighted toward advanced coursework outcomes at the high school level rather than district-wide performance against state standards. The per-pupil spending figure is drawn from the US Census Bureau Annual Survey of School System Finances for fiscal year 2023, which reports in thousands; no state average figure is available on file for comparison.

How to read New York accountability

New York's school accountability system operates under a tiered support model that classifies schools based on performance indicators. The model includes several categories, ordered from least to most intensive intervention. Local Support and Improvement, or LSI, is the baseline tier for schools that do not meet the criteria for required state- or district-led intervention. Below LSI sit more intensive tiers: Comprehensive Support and Improvement, or CSI, which applies to schools with the lowest performance across multiple indicators, and Targeted Support and Improvement, or TSI, which applies to schools where specific student subgroups are underperforming. The New York State Education Department publishes these designations and provides an overview of the support model.

The state's growth measure is not published as a district-level value-added result for the 2025-26 cycle. NYSED released final accountability determinations for 2025-26 based on 2024-25 results, but the department does not produce a standalone district-level growth score. A district's standing derives from its individual schools' support-model statuses rather than from a composite district metric.

The tax levy limit, commonly called the property tax cap, is established by New York Education Law Section 2023-a. It limits the amount by which a school district can increase its tax levy from one year to the next, generally to the lesser of 2 percent or the rate of inflation, with certain exemptions for specific cost categories such as debt service and pension contributions. If a school district proposes a budget that would exceed the levy limit, the budget must be approved by at least 60 percent of voters. If the budget fails to achieve that supermajority, the district must either resubmit a revised budget for a second vote or adopt a contingency budget that caps the levy at the prior year's level. The New York State Library provides additional detail on the mechanics of the cap.

New York authorizes charter schools under state law, but no charter schools are described in the available materials for Ardsley Union Free School District. The district does not operate a general open-enrollment program; non-resident students may attend only by board action with tuition, not through a general choice mechanism.

For Ardsley specifically, all three schools are designated under the Local Support and Improvement model for the 2025-26 accountability cycle. This means none of the district's schools meet the threshold for CSI or TSI designation, and the district is not subject to state- or district-led intervention under the accountability framework. The district's tax levy is subject to the cap under Section 2023-a, and the Board of Education's annual budget vote in May is the mechanism through which voters approve or reject the proposed levy. If the budget is defeated, the two-strike process allows one revised resubmission before the contingency framework takes hold for that fiscal cycle.

What kind of district this is: governance and geography

Ardsley Union Free School District is a Union Free School District organized under New York Education Law. The Union Free designation is a category of New York school district that is independent and governed by an elected Board of Education, distinct from Central School Districts, which are typically rural consolidations formed under Article 37 of the Education Law, and from City School Districts, which operate under Article 39. The district serves grades K through 12 and reported a total enrollment of 2,324 students in the 2023-24 school year, according to data from the National Center for Education Statistics. It operates three schools, all currently open: Concord Road Elementary School, Ardsley Middle School, and Ardsley High School. The district's official website is ardsleyschools.org, and its administrative headquarters are located in the village of Ardsley.

The district is a single, self-contained K-12 system. It is not part of a multi-district feeder system, meaning that students who attend elementary school within the district generally continue through middle and high school within the same district rather than being tuitioned out to a neighboring district at any grade level. Concord Road Elementary School serves the elementary grades, Ardsley Middle School serves the intermediate grades, and Ardsley High School serves the secondary grades. This three-school structure means the district manages the full educational continuum from kindergarten through graduation without relying on external districts for any portion of its students' enrollment.

Taxing authority and budget approval

The school tax in Ardsley UFSD is levied by the district itself. The Board of Education adopts a budget, which is then subject to voter approval at an annual election held in May. Once voters approve the budget, the Board of Education, by operation of New York Education Law Section 2023-a, which establishes the tax levy limit commonly referred to as the property tax cap, fixes the tax levy against all taxable property within the district's boundaries. The Town of Greenburgh, through its tax department, collects the tax on its town tax rolls and remits the proceeds to the district. This means that while the district determines how much to levy, the actual collection mechanism runs through the town's property tax infrastructure.

If voters defeat the proposed budget at the May election, the Board of Education is required by law to adopt a contingency budget. Under Education Law Section 2023-a, a contingency budget caps the tax levy at the prior year's level, which translates to a zero percent levy increase. Certain categories of spending are statutorily excluded from this cap and may be funded above it, including debt service, pension contributions, court-ordered judgments, and certain health insurance cost increases. The Board of Education also has the option to resubmit a revised budget to voters for a second vote. If that revised budget is also defeated, the contingency budget governs for the remainder of the school year. This two-strike mechanism means that a community has two opportunities to pass a budget before the contingency framework takes permanent hold for that fiscal cycle. Information about the district's annual budget process is available on the district's budget page and its board of education election information page.

Board of education composition and elections

The Ardsley Board of Education consists of five members, each elected to a three-year term. Elections are conducted at large, meaning that all voters within the district vote for all board seats regardless of where within the district they reside, rather than voting by sub-district or geographic zone. Board members are elected rather than appointed. The next scheduled board election date, according to the district's governance structure, is May 18, 2027. Board elections are held concurrently with the annual budget vote, so voters in the district act on both the budget and board candidates in the same election. Additional information about the board is available on the district's board of education page.

Municipalities served and shared boundaries

The district's boundaries encompass territory in multiple municipalities within Westchester County. The village of Ardsley is served in its entirety by the district. The village of Dobbs Ferry is served in part, with the Dobbs Ferry Union Free School District also serving portions of that village. The town of Greenburgh is also served in part by Ardsley UFSD, and because Greenburgh is a large town containing multiple school districts, several other districts also serve portions of it: Edgemont Union Free School District, Greenburgh Central School District, Hastings-on-Hudson Union Free School District, Irvington Union Free School District, Pocantico Hills Central School District, Tarrytowns Union Free School District, and Valhalla Union Free School District. This means that a property's address in Greenburgh or even in Dobbs Ferry does not by itself determine which school district serves it, and families should verify the specific district assignment for any given property rather than relying on municipal boundaries alone. The village of Ardsley's own website and the town of Greenburgh's schools page provide additional municipal-level context.

Boundary change mechanism

Changing the boundaries of Ardsley UFSD is a formal legal process governed by New York Education Law Sections 1507 and 1508, and administered by the Commissioner of Education under Education Law Section 314, which addresses the Master Plan for School District Organization. The process begins with a petition to the District Superintendent of Supervisory District No. 1, which covers Westchester County. Under Section 1507, the boards of education of all affected districts must consent in writing to the proposed alteration. If all affected boards consent, the process can proceed relatively directly through the Commissioner's review. If one or more affected boards do not consent, the longer and more complex process under Section 1508 applies. That process involves a feasibility study, public hearings in the affected territory, and typically requires voter ratification by residents of the affected areas. It is important to note that a municipal boundary change, such as a village annexation or incorporation, does not by itself move school district lines. A separate alteration order under the Education Law is required to change which school district serves a given piece of territory, even if the municipal boundaries have already shifted. This separation of municipal and school district boundaries is a structural feature of New York governance that can create situations where a property's municipal address and its school district assignment do not align.

Academic outcomes: the evidence base

The computed assessment data on file for Ardsley Union Free School District comprises 61 distinct series spanning the 2006 school year through 2025. These series track proficiency rates on Advanced Placement examinations across multiple subjects and grade levels, with the most recent data points available from the 2023-24 school year. The data file also includes graduation rate information from 2019-20 and chronic absenteeism figures from 2022-23. Together, these datasets form the available evidence base for describing academic outcomes in the district, though each captures a different facet of student performance and applies to a different population.

What the assessment data measures

The assessment series on file are AP examination results. They are not the New York State Regents exams or the grades 3-8 English language arts and mathematics assessments that constitute the core of the state's testing and accountability system. AP proficiency, as recorded in these series, represents the percentage of students who took a given AP exam and achieved a score considered proficient. In New York's AP reporting framework, proficiency on an AP exam denotes a score of 3 or higher on the College Board's 5-point scale. A score of 3 is generally treated as the minimum for potential college credit, though credit-granting policies vary by institution and by subject.

The AP proficiency rate therefore reflects outcomes for the subset of students who enrolled in an AP course, sat for the corresponding exam, and achieved a qualifying score. It does not reflect the performance of students who did not take AP courses, students who took AP courses but did not sit for the exam, or students in other course pathways such as honors, Regents-level, or dual-enrollment programs. The district offers SUPA (Syracuse University Project Advance) courses as one such alternative pathway, according to its high school academic page, but outcomes from those courses are not represented in the computed assessment data.

Current levels: AP results for 2023-24

For the 2023-24 school year, the computed data reports proficiency rates across several AP subjects and grade levels. In AP Biology, 95.5 percent of 11th-grade test-takers achieved proficiency, and 100.0 percent of 12th-grade test-takers did so. In AP Calculus AB, the 12th-grade proficiency rate was 69.2 percent; the 11th-grade figure for this subject is recorded as missing. AP Calculus BC, reported at the 12th-grade level, shows a 100.0 percent proficiency rate. In AP Chemistry, 91.7 percent of 11th-grade test-takers achieved proficiency; the 12th-grade figure is missing. AP Comparative Government and Politics shows a 100.0 percent proficiency rate at the 12th-grade level, with the 11th-grade figure missing.

Additional series exist in the data file for subjects including AP Chinese Language and Culture at grades 9 and 10, AP Computer Science A at grade 11, and others, but the 2023-24 data points for these series are recorded as missing. Missing values in AP data can arise from several mechanisms: a course may not have been offered at that grade level, the number of test-takers may have been too small to report under privacy suppression rules, or the data may not have been submitted in a reportable form. The computed data does not distinguish among these causes.

The 61 series on file cover a range of AP subjects, but only a portion have reported values for 2023-24. The subjects with reported proficiency rates span mathematics, science, and social studies. The available data provides a partial view of AP outcomes rather than a comprehensive accounting of every AP course offered in the district. The district's high school program planning guide for 2025-26 lists the full catalog of courses available, but the computed assessment data captures only those subjects and grade levels for which exam results were reported to the state.

Trajectory: multi-year context and the pandemic gap

The assessment series on file span from 2006 through 2025, which in principle allows for longitudinal analysis. The years associated with the series corpus include 2006 through 2017, indicating that earlier years of data exist in the underlying records. However, the specific data points displayed in the computed output are concentrated in the 2023-24 school year, and the file does not present year-over-year proficiency rates for individual subjects across the full span. Treating trajectory as a question separate from current levels: the computed data on file does not provide the year-by-year data points needed to construct an independent trend line for any single AP subject.

One structural discontinuity affects any longitudinal comparison of New York assessment data: the state cancelled its spring 2020 assessments in response to the COVID-19 pandemic. This cancellation applied to Regents exams and grades 3-8 tests, creating a gap in the state testing record for that year. AP exams, administered by the College Board rather than the state, followed a different path. The College Board administered shortened, online AP exams in May 2020, but participation patterns and score distributions that year were not comparable to prior or subsequent years. Any trend analysis spanning the 2019-20 to 2021-22 window must account for these disruptions to both state and AP testing.

The district has commented on its own AP trends. In a January 27, 2026 Board presentation, the district stated that AP performance increased, noting that the number of students earning a 3 or 4 on AP exams had risen. This is a self-reported claim by the district. The computed data on file does not independently confirm or refute it, as the visible data points are limited to 2023-24 and do not include prior-year comparison figures for the same subjects and grade levels.

What the data does not capture

The AP proficiency data describes outcomes for a self-selected group of students who took AP exams. It does not measure the performance of the full student body on state learning standards. New York's accountability system relies primarily on Regents exam results and grades 3-8 assessments, neither of which appears in the computed assessment series on file for this district. Regents exams are the state's required high school assessments in English, mathematics, science, and social studies, and they apply to all students regardless of course level. Their absence from the computed data means the available assessment evidence is weighted toward advanced coursework outcomes at the high school level rather than district-wide performance against state standards.

The computed data also does not include grades 3-8 state assessment results in English language arts or mathematics. These assessments, administered annually to all students in those grades, provide a broader measure of student performance across the full enrollment in the elementary and middle grades. Without them, the assessment picture is limited to the high school's AP-taking population. The district's middle school mathematics page describes the math curriculum pathway leading into high school, but assessment results for those grade levels are not in the computed file.

Subgroup data in the assessment series

The computed assessment series on file for Ardsley report results for the "all students" group only. No subgroup breakdowns by race, ethnicity, economic status, disability status, or English learner status are available in the AP proficiency data. This means the data cannot speak to how different student groups performed on AP exams relative to one another.

The enrollment data, by contrast, does include race and ethnicity counts for 2023-24. Of the 2,324 enrolled students, 1,221 were white (52.5 percent), 497 were Asian (21.4 percent), 341 were Hispanic (14.7 percent), 183 were two or more races (7.9 percent), 79 were Black (3.4 percent), 2 were American Indian or Alaska Native (0.09 percent), and 1 was Native Hawaiian or Pacific Islander (0.04 percent). These figures describe the composition of the student body. They do not describe assessment performance by group, as that breakdown is not in the computed data.

Free and reduced-price lunch counts and rates are recorded as missing, as are counts and rates for students with individualized education programs and English learners. The absence of these figures means the computed data cannot speak to the economic composition of the student body or the size of special populations served by the district.

Graduation rate

The graduation data on file is from the 2019-20 school year and represents the most recent graduation information available. The four-year adjusted cohort graduation rate for that year is reported as a suppressed range of 95 to 100 percent, based on a cohort of 162 students. The range, rather than a single figure, reflects federal privacy suppression rules that apply when small numbers of students could be identified from a precise rate. No midpoint should be inferred from this range; the data indicates only that the rate falls somewhere within the 95-to-100-percent band. This data is several years old and predates the full effects of pandemic-era learning disruptions on subsequent graduation cohorts.

Chronic absenteeism

The chronic absenteeism rate for the 2022-23 school year was 9.4 percent, according to EDFacts Data Group 814. Chronic absenteeism, as defined by New York State, refers to students missing 10 percent or more of enrolled school days, whether the absences are excused or unexcused. This figure provides a measure of student engagement across the full enrollment, complementing the AP data, which captures only the advanced coursework subset.

Accountability status

For the 2025-26 accountability cycle, Ardsley's schools are designated under the Local Support and Improvement (LSI) model. According to the New York State Education Department, LSI is the locally managed category for schools that do not meet the criteria for required state- or district-led intervention. NYSED released final accountability determinations for 2025-26 based on 2024-25 results. The department does not publish a district-level growth or value-added result for 2025-26; the district's standing derives from its individual schools' support-model statuses. The LSI designation represents the baseline level of New York's accountability framework, below which more intensive support tiers such as Comprehensive Support and Improvement and Targeted Support and Improvement apply, as described in the state's support model overview.

Inside the district: variation between schools

The Ardsley Union Free School District operates three schools, each serving a distinct grade band with no overlap. Concord Road Elementary School serves the district's youngest students. Ardsley Middle School serves the intermediate grades. Ardsley High School serves the upper grades. This structure means that within any given grade level, all students in the district attend the same school. There is no variation between schools at the same level to report, because there is only one school at each level.

This single-feeder structure has practical implications for how a family should interpret district-level data. When the district reports an AP Biology proficiency rate of 95.5 percent for grade 11 students in the 2023-24 school year, that figure reflects performance at Ardsley High School specifically, because no other school in the district offers AP coursework or enrolls grade 11 students. Similarly, the grade 12 AP Calculus AB proficiency rate of 69.2 percent for 2023-24 is a high school figure. The district-level data and the high school-level data are, for AP purposes, the same data.

The same logic applies in reverse for the elementary and middle schools. The available assessment data in the computed profile corpus for this district consists primarily of AP exam proficiency rates, which are high school metrics. There is no comparable school-level state assessment data broken out by individual school in the data on file. This means the data cannot speak to how Concord Road Elementary compares to Ardsley Middle School on any shared metric, because the two schools serve different grade levels and do not take the same exams.

What the AP data does show is variation across subjects within the high school. In the 2023-24 school year, AP Biology proficiency rates were 95.5 percent for grade 11 test-takers and 100 percent for grade 12 test-takers. AP Calculus AB showed a proficiency rate of 69.2 percent for grade 12, while AP Calculus BC showed 100 percent proficiency for grade 12. AP Chemistry showed a 91.7 percent proficiency rate for grade 11, with grade 12 data reported as missing. AP Comparative Government and Politics showed 100 percent proficiency for grade 12. Several additional subjects and grade combinations appear in the data with missing values, including AP Computer Science A for grade 11 and AP Chinese Language and Culture for grades 9 and 10.

These subject-level differences within a single school are the closest available analogue to variation between schools in a district that has only one school per level. A family evaluating this district should understand that the relevant variation is not between buildings but between academic programs and subjects within the high school. The 30.8-point gap between the AP Calculus AB and AP Calculus BC grade 12 proficiency rates in 2023-24, for example, reflects different student populations and course structures rather than different school quality, since both courses are taught in the same building.

The district's enrollment of 2,324 students in 2023-24 is distributed across the three schools, but the computed data does not include a per-school enrollment breakdown. Race and ethnicity data is reported at the district level: 1,221 white students (52.5 percent), 497 Asian students (21.4 percent), 341 Hispanic students (14.7 percent), 183 students of two or more races (7.9 percent), 79 Black students (3.4 percent), 2 American Indian or Alaska Native students (0.09 percent), and 1 Native Hawaiian or Pacific Islander student (0.04 percent). Without school-level breakdowns, it is not possible to describe how these figures distribute across the three buildings.

Data on free or reduced-price lunch eligibility, Individualized Education Program counts, and English learner counts are all reported as missing in the computed data. This means the profile cannot address whether special population rates vary between the elementary, middle, and high school levels.

The high school's own publications provide additional context about its academic offerings. According to the Ardsley High School profile for 2025-26, the school reports SAT and ACT scores, college enrollment outcomes, and National Merit recognition. The high school also maintains a science research program and offers SUPA courses, which are Syracuse University Project Advance courses through which students can earn college credit. The program planning guide for 2025-26 describes the full course catalog. At the middle school level, the mathematics program page describes the curriculum. None of these resources provide a basis for comparing outcomes between the district's three schools, because each school serves a different segment of the K-12 continuum.

For families considering this district, the structural takeaway is that school choice within the district is not a variable. Residence anywhere in the district maps to the same three-school sequence. The variation that exists is temporal and programmatic, concerning how a student progresses through the system and which courses they select at the high school level, rather than spatial, as it would be in a district with multiple elementary or middle schools feeding into a shared high school. The New York State Education Department publishes school and district accountability determinations and chronic absenteeism data through its public reporting systems, and families seeking school-level accountability status can consult those state resources directly. The computed data on file for this district does not include a school-by-school breakdown of those metrics.

Advanced academics and pathway access

Ardsley Union Free School District concentrates its most selective academic options at the secondary level. The district operates three schools, and the US Department of Education Civil Rights Data Collection for SY2021-22 aggregated advanced coursework data across all three. The available materials describe a layered system: an accelerated mathematics track beginning in middle school, a range of Advanced Placement courses at the high school, and a dual-enrollment partnership that extends the academic ceiling beyond what AP alone provides.

Advanced Placement courses and enrollment

Ardsley High School offers a range of Advanced Placement courses, as described in the district's 2025-2026 Program Planning Guide. The specific courses and their availability in any given year depend on enrollment and staffing, which the guide outlines. The district reported AP examination results from 2025 in a Board presentation on January 27, 2026, according to its own materials. The specific scores and participation rates are contained in the district's presentation materials.

According to the US Department of Education Civil Rights Data Collection for SY2021-22, 212 students were enrolled in at least one AP course across the district's three schools. The racial and ethnic breakdown of AP enrollees was as follows: 111 White students, 69 Asian students, 27 Hispanic students, 3 students of two or more races, 2 Black students, and no American Indian or Alaska Native students and no Native Hawaiian or Other Pacific Islander students. The same data collection recorded that among AP enrollees, 3 were English learners, 7 had Individualized Education Programs under IDEA, and 30 had Section 504 accommodation plans. These figures represent a single point-in-time count from SY2021-22 and reflect enrollment, not completion or examination performance. The district's total enrollment was 2,324 in 2023-24, but because the AP data predates that figure by two school years and covers only schools where AP courses are offered, direct proportional comparisons are not reliable.

No International Baccalaureate program is described in any of the available materials for Ardsley. The district's advanced offerings at the high school level consist of AP courses, the SUPA dual-enrollment program, and the Science Research Program.

Grade 8 Algebra I and the accelerated mathematics sequence

At Ardsley Middle School, placement into Algebra I in grade 8 is not automatic. It is part of an accelerated mathematics sequence that the middle school describes as moving at a faster pace than the standard curriculum, typically covering two years of content within a compressed timeframe. A family whose child is on the standard mathematics track would not reach Algebra I until a later grade. Entry into the accelerated sequence is determined by criteria that the middle school establishes, and the middle school mathematics page describes the accelerated option as one available pathway among others. The mechanics of selection are not fully detailed in the available materials, but the structure is clear: the accelerated track exists as a distinct pathway, and students must meet whatever criteria the school applies to enter it rather than being enrolled by default.

The Civil Rights Data Collection for SY2021-22 includes Algebra I enrollment data for the district, aggregated across three schools. The computed data from this collection does not provide specific enrollment counts broken down by grade level or subgroup for Algebra I. This means the available data confirms that Algebra I enrollment was tracked but does not allow a reader to determine how many grade 8 students specifically were enrolled in the course during that year.

Gifted and talented identification

The Civil Rights Data Collection for SY2021-22 includes gifted and talented enrollment data for the district, aggregated across three schools. The computed data does not provide specific enrollment figures, identification methods, or demographic breakdowns for gifted programs. The district does not publicly describe a standalone gifted identification process in the available materials reviewed for this report. The absence of a described identification method means this section cannot detail the specific mechanism by which students are identified for gifted services, if such services exist as a formal program separate from the accelerated and AP pathways already described.

Dual enrollment and the academic ceiling

The highest-level academic option available to Ardsley High School students is dual enrollment through Syracuse University Project Advance, known as SUPA. The district describes SUPA as one of the nation's leading concurrent enrollment programs. Students who successfully complete SUPA courses have the opportunity to earn college credit through Syracuse University. This mechanism allows students to take university-level courses within the high school building and to receive transcripted credit from Syracuse University upon successful completion. This extends the academic ceiling beyond what AP courses alone provide, as students can accumulate college credit while remaining enrolled at Ardsley High School.

The district also offers the Ardsley Science Research Program, which provides students the opportunity to engage in scientific research. The program is described on the high school's academics page, though the specific entry criteria, duration, and structure of the research experience are not detailed in the materials available for this report.

The high school announced students recognized as commended in the 2026 National Merit Scholarship Program, which reflects performance on the Preliminary SAT/National Merit Scholarship Qualifying Test.

Honors placement and tracking

The available materials do not describe any formal detracking initiative, proposed changes to honors placement policies, or board resolutions regarding tracking at Ardsley. The middle school mathematics page describes an accelerated track that exists alongside a standard sequence, representing a tracked structure in which students are sorted into different pacing levels based on established criteria. The high school Program Planning Guide describes AP and SUPA options that supplement the standard curriculum rather than replacing tracked honors courses. No petitions, policy proposals, or public disputes regarding tracking or honors redesign appear in the sources reviewed for this report. This absence means that the current structure, as described, is the operating model without recorded challenge or proposed modification in the available materials.

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

The Ardsley Union Free School District enrolled 2,324 students in the 2023-24 school year across three schools, according to NCES Common Core of Data. The district operates a single school at each level: Concord Road Elementary School, Ardsley Middle School, and Ardsley High School. This structural simplicity is the single most important fact for a prospective homebuyer to understand about school assignment in Ardsley, because it eliminates the most common source of boundary instability that affects larger, multi-feeder districts. Where a district operates four elementary schools feeding into two middle schools, attendance lines can be redrawn and feeder patterns reshuffled. In Ardsley, there are no internal attendance lines to redraw.

How an address becomes a school seat

Assignment in Ardsley follows a neighborhood-zoned model, but the zone is the district itself. Once a family establishes that their address lies within the boundaries of Ardsley UFSD and completes the district's registration process, grade level alone determines placement. A resident elementary student attends Concord Road Elementary; a resident middle school student attends Ardsley Middle; a resident high school student attends Ardsley High. No internal feeder zones, attendance areas, or same-grade choice mechanisms are published, according to a review of Board of Education notifications for 2024-2025 and 2025-2026, the BoardDocs public portal, and the district's capital project hub. The district's new student registration page and the registration packet outline the documentation required.

Because there is one school per level, the question that preoccupies families in multi-elementary districts, which is which elementary school feeds which middle school and whether that feeder pattern might change, does not apply here. A buyer who confirms their address is inside the district boundary can expect that the school path runs Concord Road to Ardsley Middle to Ardsley High, with no same-grade alternative to be reassigned to.

Residency verification and enforcement

The district requires proof of age, such as a birth certificate or passport, and residency documentation at registration. Residency documentation consists of one general item, which may be a Con Edison bill, cable or water bill, bank statement, or voter registration card, plus either homeowner proof in the form of a deed or mortgage, or non-homeowner proof in the form of a signed and dated lease. Renters and families in shared-housing arrangements must submit notarized affidavits. These requirements are detailed in the registration packet.

No routine audit protocol is published. Verification appears to be document-based at the point of registration, with notarized affidavits required where standard documentation is not available. The district states that it will seek restitution for tuition if it determines that a child is not a resident student. This means the enforcement mechanism is retrospective: the district does not publish a schedule of residency audits, but it reserves the right to pursue tuition recovery if a non-resident enrollment is discovered after the fact. A family considering a move should understand that the gatekeeping happens at registration, not through ongoing monitoring, and that the restitution provision gives the district a financial remedy if residency is later found to be invalid.

Capacity and utilization

No published standalone utilization study with school-level utilization percentages was located in a review of district facilities and operations materials. The district does not publish a building-by-building capacity report that would allow a buyer to compare current enrollment against rated capacity at each school. This is a meaningful absence: without a utilization study, there is no district-acknowledged benchmark against which to measure whether a particular building is approaching its functional limit. A buyer cannot independently determine whether Concord Road Elementary is at 70 percent or 95 percent of capacity, because the district has not published the denominator.

What the district does provide is evidence of capital investment. The district broke ground on a $50 million capital improvement project, as reported on the district's website. The capital project page provides additional information. Capital investment of this scale indicates that the district is maintaining and upgrading its physical plant, but it does not by itself indicate whether enrollment is growing, declining, or stable relative to building capacity. A capital project can address deferred maintenance, code compliance, accessibility, programmatic expansion, or infrastructure renewal without signaling enrollment pressure in either direction. The official statement associated with district financing may contain additional enrollment and capacity disclosures, but no standalone utilization study was identified in the materials reviewed.

A long-run enrollment series is not available on file. The single data point on file is the 2023-24 enrollment of 2,324 students from the NCES Common Core of Data. Without multiple years of comparable data, it is not possible to describe an enrollment trend, and this report does not imply one. The district's budget documents and board actions reflect non-resident tuition activity, including out-of-district special education placements paid by sending districts, which indicates some external demand for district programs but does not quantify internal enrollment pressure or direction.

Boundary and redistricting activity

No active boundary study, redistricting process, or school closure or consolidation plan was found as of a review conducted through July 2026. The review covered Board of Education notifications for 2024-2025 and 2025-2026, the BoardDocs public portal for meeting items, and the capital project hub and related district news posts. This is an explicit null: the district is not currently engaged in a published process to redraw attendance lines, close a school, or consolidate programs.

The absence of active boundary activity is structurally reinforced by the district's one-school-per-level design. In a district with multiple elementary schools feeding into a smaller number of middle schools, boundary changes are a routine tool for rebalancing enrollment across buildings. In Ardsley, there are no internal attendance lines to redraw. The only boundary that matters is the district boundary itself, which is defined by the geographic limits of the areas the district serves within Westchester County. Changes to that external boundary are not something a school district unilaterally initiates. They involve state-level processes, annexation proceedings, or legislative action, and they are rare.

What would signal potential boundary or capacity changes in the future? A buyer should watch for several indicators. First, the publication of a district-commissioned demographic study or enrollment projection would signal that the district is examining whether its facilities can accommodate future enrollment. Second, board of education discussion of building utilization, particularly if tied to the capital project, would indicate attention to capacity constraints. Third, any proposal to add, remove, or reconfigure grade spans at a particular school would signal structural change. Fourth, the appearance of a redistricting committee or consultant engagement on a board agenda would be a concrete signal. None of these signals is present in the materials reviewed. The Board of Education notifications page and the BoardDocs portal are the appropriate venues to monitor for such developments, and a buyer can review them directly.

Transfer mechanics

No ordinary in-district transfer mechanism is published. With one school per level, regular assignment offers no same-grade choice, so there is no internal transfer process to administer. A family cannot request a different elementary school because there is only one. This eliminates a category of uncertainty that exists in choice-based or multi-school districts, where transfer approvals can depend on seat availability, lottery outcomes, or administrative discretion.

At the inter-district level, the district does not operate a general open-enrollment program. The board of education sets non-resident tuition rates, and the budget reflects non-resident tuition activity, which the district characterizes as limited. This includes out-of-district special education placements paid by sending districts. A non-resident student may attend Ardsley schools only by board action and with tuition, not through a general open-enrollment policy. The distinction matters: open enrollment would imply a programmatic commitment to accepting outside students as a matter of course, while tuition students by board action implies case-by-case decisions that do not create a pathway for general public access.

Grandfathering

No grandfathering policy is published, and the absence is consistent with the district's structure. Grandfathering typically arises when a boundary change would move students from one school to another, and the district allows current students to remain at their original school through a terminal grade. Because Ardsley has no internal boundaries to change and no active redistricting process, a grandfathering policy has no current trigger. If a boundary change or closure were proposed in the future, a grandfathering provision would likely be addressed at that time as part of the transition plan, but no such provision exists in the materials reviewed.

Enrollment composition

The district's 2023-24 enrollment of 2,324 students is distributed across the three schools, but school-level enrollment breakdowns are not available in the computed data on file. The district reports the following racial and ethnic composition for 2023-24: 1,221 white students, representing 52.5 percent of enrollment; 497 Asian students, representing 21.4 percent; 341 Hispanic students, representing 14.7 percent; 183 students of two or more races, representing 7.9 percent; 79 Black students, representing 3.4 percent; 2 American Indian or Alaska Native students; and 1 Native Hawaiian or Pacific Islander student. Free and reduced-price lunch data, Individualized Education Program counts, and English learner counts are all reported as missing in the data on file. These figures describe who is enrolled. They do not predict capacity, boundary stability, or assignment risk, and they should not be interpreted as indicators of program quality or school fit.

What a buyer should monitor

The structural factors in Ardsley point toward assignment stability in the specific sense that matters most to a homebuyer: the district has one school per level, no internal boundaries to redraw, no active redistricting or closure process, and no published capacity utilization study indicating strain. The $50 million capital project indicates investment in facilities. The primary source of assignment risk in this district is not internal boundary change but external, meaning the district boundary itself, which is fixed by geography and state-level processes rather than by local board action. A buyer who confirms their address is within the district boundary can expect a predictable path through all three schools, with residency verification at registration as the gatekeeping mechanism. To monitor for future changes, a buyer should check the Board of Education notifications page and the BoardDocs portal for agenda items related to enrollment studies, capacity reports, or facilities planning.

Fiscal health and the tax picture

Per-pupil spending and revenue structure

According to the US Census Bureau Annual Survey of School System Finances (F-33) for FY2023, the Ardsley Union Free School District reported current spending of approximately $29,805 per pupil across a membership base of 2,298 students. Of that amount, approximately $20,870 per pupil went to instruction, which encompasses teacher salaries, classroom materials, and direct educational services. The remainder covered support services, administration, transportation, and other operational costs that fall within the definition of current spending but outside direct instruction. Total revenue for FY2023 was approximately $81.6 million, and total expenditure was approximately $81.3 million.

The district's revenue mix for FY2023 was heavily local: 80.7% came from local sources, primarily property taxes; 17% came from state aid; and 2.3% came from federal sources. In dollar terms, local revenue totaled approximately $65.9 million, state revenue approximately $13.9 million, and federal revenue approximately $1.9 million. This structure means the district's fiscal health is tied closely to the local property tax base and to voter willingness to approve annual budgets and bond measures. State aid, the second-largest source, is determined by formulas that consider district wealth and enrollment, and it fluctuates with state budget decisions. Federal revenue, the smallest share, is typically tied to specific categorical programs rather than general operations.

Adopted budget and structural balance

The district's adopted budget for 2026-27 totals $91,073,716, a 6.35% increase over the prior year. Voters approved it in May 2026 by a margin of 803 yes to 297 no, or 73% to 27%. The budget is legally balanced, as New York State law requires. However, it achieves balance in part by drawing on $1,980,000 of fund balance and $2,074,438 of reserves rather than relying on recurring revenue alone. This means the district is using accumulated savings to support current operations, a practice that cannot continue indefinitely without either revenue increases or expenditure reductions.

The district's own projections underscore this tension. An April 7, 2026 budget workshop projected a $4,361,151 operating deficit for FY2025-26, with total fund balance falling from $26,441,992 at June 30, 2025 to $22,080,840 at June 30, 2026. The district does not officially claim that its budget is structurally balanced, and the budget documents confirm that non-recurring resources are being used to close the gap between ongoing expenditures and ongoing revenues. A structurally balanced budget, by contrast, would fund all recurring expenditures with recurring revenues without drawing down reserves.

Federal pandemic relief

The district, like all New York districts, received federal ESSER and ARP pandemic-relief funding, which has now expired. The primary district, state, and offering documents reviewed did not specify which recurring positions or programs were cut, backfilled, or absorbed after ESSER and ARP expiration. The absence of this information in public budget documents means that residents cannot determine from those documents alone how the loss of federal relief affected specific programs or staffing levels. Whether the current operating deficit and reserve drawdowns are partly attributable to the loss of these federal funds cannot be confirmed from the available materials.

Reserves

The unassigned General Fund balance stood at $3,420,997 as of June 30, 2025, equal to 4.00% of the ensuing 2025-26 budget, according to the district's own figures. This figure has grown modestly over four years: $3,067,662 at FY2022 year-end, $3,275,467 at FY2023, $3,371,603 at FY2024, and $3,420,997 at FY2025. However, the total fund balance tells a different story. It was projected to decline from $26,441,992 at June 30, 2025 to $22,080,840 at June 30, 2026, reflecting the use of reserves and fund balance to support operations.

The distinction matters because the unassigned fund balance is the portion available for appropriation without restriction, while the total fund balance includes amounts already committed or assigned to specific purposes. A district can have a substantial total fund balance while its unassigned balance remains thin, which limits flexibility in responding to unexpected costs or revenue shortfalls. In Ardsley's case, the unassigned balance of approximately $3.4 million represents roughly 4% of the annual budget, while the total fund balance of approximately $26.4 million includes restricted, committed, and assigned portions that are not freely available for general operations.

Debt and capital

As of May 7, 2026, the district had $48,455,844 in outstanding debt. The 2026-27 budget includes a $5,888,562 transfer to debt service, which equals 6.47% of the $91,073,716 budget by calculation, though the budget documents did not publish this percentage. The May 2026 official statement separately lists $2,469,175 of FY2026 long-term debt service.

In May 2024, voters approved a $53,499,000 capital project financed with $3.5 million from the Capital Reserve Fund-2017 and up to $49,999,000 in bonds. This capital program addresses Building Condition Survey-prioritized work plus safety and instructional-space projects. The passage of this measure by a vote of 821 to 430 authorized the district to issue bonds that will increase future debt service obligations.

In 2026, voters also approved two additional capital measures: a $5,000,000 capital reserve use for boilers, HVAC, building-management systems, flooring, a pool dehumidifier, and a scoreboard; and the establishment of a new Capital Reserve Fund-2026 with a $10 million maximum over ten years. The latter does not authorize immediate spending but creates a mechanism for future capital projects to be funded without separate bond votes, subject to voter approval of each expenditure from the fund.

Long-term obligations

The FY2024 audit reported net pension liabilities of $2,141,316 for the New York State and Local Retirement System (ERS) and $2,144,314 for the Teachers' Retirement System (TRS). The November 2025 official statement reports a total Other Post-Employment Benefits (OPEB) liability of $79,168,137 as of June 30, 2025. OPEB represents the district's obligation to provide retiree health insurance and other post-employment benefits. These figures represent accrued liabilities that the district must address over time, either through annual contributions, trust funding, or future benefit changes. The OPEB liability in particular is substantial relative to the annual budget, and how the district manages this obligation will affect its fiscal position in future years.

Credit rating

Moody's assigned the district an Aa1 credit rating, with the most recent action being an upgrade on January 20, 2023. The Aa1 rating is the second-highest tier in Moody's scale. A higher rating typically lowers borrowing costs when the district issues bonds, because investors demand less interest to hold debt they perceive as lower risk. The upgrade in 2023 indicates that Moody's assessment of the district's creditworthiness improved at that time.

Tax levy and the cap

For 2026-27, the district calculated a maximum allowable levy of $68,078,986 under New York's property tax cap law and adopted a levy of $67,000,000, which is $1,078,986 below the limit. No 60% supermajority override vote was required. New York's tax cap law, enacted in 2011, generally limits annual levy increases to the lesser of 2% or the rate of inflation, unless 60% of voters approve an override. The cap applies to the total levy, not to individual tax bills. By staying below the cap, the district avoids the need for an override vote.

The district has no history of tax-cap overrides in the measure records available. All annual budgets put before voters in recent years have passed: the 2026-27 budget of $91,073,716 passed 73% to 27%, the 2025-26 budget of $85,633,828 passed 77% to 23%, and the 2024-25 budget of $84,290,149 passed with 890 yes to 359 no. No additional money measures beyond the 2026 votes are identified in the available documents.

How the levy becomes a household tax bill

The connection between the district's levy and a household's tax bill works through a straightforward mechanism. The district determines the total amount it needs to raise from property taxes, which is the levy. The assessor determines the taxable assessed value of each property in the district. The tax rate is then calculated by dividing the total levy by the total taxable assessed value of all properties in the district and expressing the result as a rate per $1,000 of assessed value. A homeowner's school tax bill equals their property's assessed value divided by 1,000, multiplied by that tax rate.

For 2025-26, the tax rate in the Town of Greenburgh was $19.8388 per $1,000 of assessed value. A property assessed at $500,000 would generate a school tax bill of approximately $9,919 for that year. The rate has declined over five years, from about $22.71 per $1,000 in 2021-22 to $19.84 in 2025-26, while the levy rose from roughly $60,000,000 to $64,800,000. This means that total assessed value grew faster than the levy over that period, causing the per-$1,000 rate to fall even as the total amount collected rose. The adopted 2026-27 levy is $67,000,000, but its corresponding tax rate had not yet been posted as of the available documents.

Among neighboring districts in the Town of Greenburgh for 2025-26, Ardsley's rate of $19.8388 was comparable to Dobbs Ferry's $19.9512 and Irvington's $19.1951, higher than Hastings-on-Hudson's $18.8488, and higher than Elmsford's $15.9467 and Greenburgh Central 7's $13.7778. These differences reflect variations in levy, total assessed value, and revenue mix across districts.

Tax base concentration

The district's tax base includes several large commercial and utility properties. Consolidated Edison is the largest single taxpayer, accounting for 5.15% of assessed valuation, or $159,449,400. The next largest are Lincoln Dobbs Ferry LLC at 2.04% ($63,201,000) and BMR-Ardsley Park LLC at 1.92% ($59,344,900). The top ten taxpayers collectively represent roughly 14% of the district's assessed valuation. Concentration in the tax base means that a successful tax challenge or reassessment of a large property could shift a disproportionate share of the levy onto other taxpayers, potentially increasing their individual bills even if the total levy remains unchanged.

The municipal and land-use context

Ardsley Union Free School District operates within the Town of Greenburgh in Westchester County, New York. The district's budget process is structurally separate from municipal governance: the Board of Education proposes a school budget, district voters approve or reject it in an annual vote, and the district then raises a property-tax levy subject to New York State's tax-cap rules. No town board, village board, or county legislature sets the school budget or determines the district's tax levy. This separation means that municipal-level fiscal decisions, including the incorporation of new villages, do not directly alter the school district's revenue authority, boundaries, or governance.

Proposed incorporation of the Village of Edgemont

The most significant municipal-structure change active in the Town of Greenburgh is the proposed incorporation of the Village of Edgemont. The Edgemont Incorporation Committee filed Petition No. 3 with the Greenburgh Town Clerk on July 15, 2024, seeking to create a new village within the town. The Town of Greenburgh held a petition-sufficiency public hearing on September 18, 2024. Greenburgh Town Supervisor Paul Feiner issued a decision denying the petition on September 27, 2024. The Westchester County Supreme Court annulled that denial on March 6, 2026, directing the respondents to take steps necessary to conduct an incorporation election within a specified period. The Appellate Division, Second Department, granted expedited treatment for appeals from related orders on April 13, 2026, and on July 15, 2026, ordered three related appeals to be calendared and heard together. The matter remains in litigation.

The relevance of this incorporation effort to Ardsley UFSD is indirect. The proposed village boundaries align with the Edgemont Union Free School District, a separate district, not Ardsley UFSD. No party to the incorporation proceedings identified a direct fiscal change to Ardsley UFSD. The Center for Governmental Research (CGR), which conducted a state-sponsored impact study with a presentation dated March 20, 2024, stated that it had modeled three scenarios for the proposed village and the Town of Greenburgh but did not project changes to Ardsley UFSD's boundaries, governance, or levy. Any effect on Ardsley would be through shared Town of Greenburgh services and townwide taxes rather than through school-district mechanisms.

The fiscal positions of the parties differ sharply and remain contested. The Greenburgh Town Board, in its formal response to the CGR report dated April 3, 2024, projected an operating-fund loss and the termination of 25 to 30 full-time positions if incorporation occurred. The Edgemont Incorporation Committee, in its own response, argued that the proposed village would be viable at current tax levels under a lean, contract-based government model and asserted that the village would bear no liability for Town Outside Villages obligations related to other post-employment benefits, litigation, or tax-certiorari claims. CGR stated that its report modeled three scenarios for Edgemont Village incorporation. These are each party's stated positions, not settled findings.

Federal fair-housing settlement

Westchester County was subject to a 2009 federal fair-housing settlement, United States v. Westchester County, which required the county to build or finance affordable housing units in eligible communities and to take specific actions related to zoning and housing analysis. The settlement was terminated on August 4, 2021, after the county met its obligations under the consent decree. This was a county-level matter. No continuing mandate from that settlement affects Ardsley UFSD's budget, governance, or boundaries. The settlement's history provides context for land-use and housing discussions in Westchester County, but it does not impose any active obligation on the school district.

No boundary-change proposals on record for Ardsley UFSD

A review of the Ardsley UFSD official website, budget materials, and Board records, as well as New York State Education Department and State Comptroller sources, found no proposals for merger, consolidation, deannexation, annexation, split, or boundary change involving Ardsley UFSD. The absence of any such proposal is an answer: as of the research date, no movement to alter Ardsley UFSD's boundaries or governance structure is on record.

What municipal changes would affect this district

Because Ardsley UFSD's budget and tax levy are set by the Board of Education and district voters, not by any municipal body, the mechanisms by which a municipal change could affect the district are limited and specific. A change in school district boundaries through annexation, consolidation, or deannexation under New York State Education Department procedures would directly affect which properties fall within the district and therefore which taxpayers support the levy. No such proposal exists.

A second mechanism is changes to the tax base within the district's existing boundaries. If property within the district received tax-exempt status, or if large-scale development altered assessed values, the district's tax base could shift, affecting the rate needed to raise a given levy. These are standard dynamics of New York school finance, not specific pending events.

A third mechanism is the New York State tax cap, which limits the annual growth in the property-tax levy a district can impose without a supermajority override vote. This cap applies to Ardsley UFSD as it does to all New York school districts and constrains budget growth regardless of municipal-level decisions.

The Town of Greenburgh's fiscal condition, monitored through New York State's Fiscal Stress Monitoring System, does not transmit directly to the school district's budget. The town posts audited financial statements and annual reports, and the State Comptroller publishes fiscal-stress designations for municipalities. These municipal fiscal indicators concern the Town of Greenburgh's operations, not Ardsley UFSD's independently governed school budget. The State Comptroller's office conducted a financial-management audit of Ardsley UFSD in 2024, but that audit concerns the district's own internal financial practices, not any municipal transmission mechanism.

Real estate and the price of admission

The computed home value index for the Ardsley Union Free School District area is $1,083,990 as of April 2026. This figure is a ZIP-level approximation drawn from Zillow's ZHVI (Zillow Home Value Index) across seven ZIP codes associated with the district through the NCES-ZCTA relationship file: 10502, 10522, 10530, 10533, 10583, 10607, and 10706. ZIP boundaries do not align with district boundaries, so this number reflects a geographic approximation rather than a precise district-wide measure. The computed rent index for the same area is $4,986 per month as of April 2026, drawn from Zillow's ZORI (Zillow Observed Rent Index) across four of those ZIP codes. The same boundary-mismatch caveat applies to the rent figure.

A Village of Ardsley-commissioned market analysis states that the school system is a primary driver of housing demand, noting that Ardsley is "most known for its high-quality schools which has created strong demand for housing within the School District and village." The report does not project future price changes or assess whether current price levels are sustainable.

Residential development pipeline

Two residential projects in the Village of Ardsley were under review as of early 2026. At 774 Saw Mill River Road, a front-yard variance was granted on February 26, 2025, enabling the demolition of an existing three-unit multifamily building and construction of a proposed nine-unit multifamily building. The variance resolution is documented in Zoning Board of Appeals records. Site-plan review for this project appeared on the March 16, 2026 Board of Trustees agenda. No official student-generation figure was published in the cited records, and no construction schedule has been made public. The tenure and bedroom mix of the proposed nine units was not published in the cited notices.

At 766 Saw Mill River Road, a proposed addition to an existing residential building was under review. No unit count, timeline, or student-generation estimate was published in the cited records for this project.

Commercial tax base

Two commercial-tax-base changes were identified. The first is an adaptive reuse of vacant commercial space as a childcare facility at 690 Saw Mill River Road, known as Pebbles to Peaks Childcare. Site-plan approval was granted on February 2, 2026, according to the Board of Trustees agenda for that date. The second is a nonresidential amended site plan and special-use-permit application at 1 Lawrence Street, listed under 1 Lawrence Ardsley LLC in the Town of Greenburgh's active Planning Board applications. A public hearing on the amended site plan was noticed for June 10, 2026, with Zoning Board review noticed in late May 2026 on a Greenburgh agenda. No assessed-value or school-tax effect was quantified in the cited notices for either project.

Tax certiorari exposure

Two tax certiorari settlements affecting the district's refund obligations were identified in public records. The larger involves 630 Saw Mill River Road, associated with Lock Up Ardsley LLC. A settlement was noticed on August 6, 2025, with the Ardsley Union Free School District's refund share stated at approximately $213,987 out of approximately $251,697 in total refunds across taxing jurisdictions. This settlement appears on the Greenburgh agenda for August 2025.

A second, smaller settlement involving Fairmont Ardsley LLC was listed on an April 9, 2025 agenda, with the district's refund share stated at approximately $1,279. No URL for this agenda item is available in the cited records.

No PILOT agreements or tax abatement programs diverting revenue from the school district were identified in the cited records. The research reviewed district budget materials, Village of Ardsley board records, Town of Greenburgh records, and Westchester County IDA press releases through July 2026.

The choice ecosystem

Ardsley Union Free School District operates three schools - Concord Road Elementary, Ardsley Middle, and Ardsley High - and does not maintain a magnet or themed-school system. Families secure seats by establishing residency within district boundaries and submitting required proof of residency documentation. There is no magnet application, themed-school lottery, or inter-district choice mechanism identified in district publications. The district's enrollment of 2,324 students in 2023-24 flows entirely from geographic attendance zones.

The district does not authorize charter schools. Under New York law, charter authorizers are the SUNY Trustees, the Board of Regents, the New York City Department of Education, and the Buffalo Board of Education. Ardsley UFSD is not an authorizer, and no charter schools operate within the district's boundaries.

New York had no enacted K-12 education savings account or voucher program as of July 2026, according to the National Conference of State Legislatures. No local fiscal effect from ESA or voucher programs was identified for Ardsley, consistent with the absence of any such statewide program.

The district tracks homeschooling and microschool activity in compliance with New York State home instruction regulations. Parents electing home instruction must file a notice of intent and an individualized home instruction plan with the district, which monitors compliance with state subject and hour requirements.

Ardsley does not operate a universal pre-kindergarten program. No district UPK seats, lottery, capacity figures, or waitlists were published. A local publication, The Hudson Independent, has reported on advocacy for universal pre-K in Ardsley, but no district-administered pre-K model exists as of the documents reviewed.

Several private schools serve families across the broader Westchester area. Tuition figures as published for the 2026-27 academic year are as follows:

  • The Leffell School, a K-12 institution, publishes tuition ranging from $35,900 to $51,900 depending on grade level.
  • Hackley School, serving K-12 day students with upper-school boarding available, publishes day tuition of $52,880 for Lower School, $58,260 for Middle School, and $61,895 for Upper School. Five-day boarding adds $18,905.
  • The Masters School, serving middle and upper school students with upper-school boarding, publishes day tuition of $65,800 for Middle and Upper School. Upper School boarding is $77,200 for five-day or $83,350 for seven-day.
  • Rye Country Day School, a Pre-K through 12 institution, publishes tuition of $53,210 for PreK through grade 4, $55,540 for grades 5-8, and $59,070 for grades 9-12.
  • Iona Preparatory School, serving Pre-K through 12, publishes an upper-school tuition figure of $22,400 for 2026-27.
  • Maria Regina High School, serving grades 9-12, publishes tuition and fees totaling $17,500.

The district transports resident pupils to nonpublic schools, but only if the school is located no more than 15 miles from the student's home. Students must also meet district minimum-mileage requirements for any transportation eligibility.

Programs, logistics, and special populations

Special Education

NYSED reported 358 students with disabilities in Ardsley UFSD in 2024-25, representing 15% of enrollment. The district's special education model operates on a continuum tailored by each student's Individualized Education Program (IEP). At the least restrictive end, collaborative and integrated assistance places support professionals in general-education classrooms, allowing students to access the standard curriculum with in-class support. Resource room and study-skills support provide targeted services, typically in a smaller setting, where students receive specialized instruction aligned with their IEP goals. For students whose IEPs call for a more structured environment, the district offers special-class and self-contained programming, where instruction is delivered in a smaller group by a special education teacher.

The district also maintains Committees on Special Education and Preschool Special Education, which are responsible for evaluation, eligibility determination, and IEP development. A Child Study Team handles initial referrals and evaluations. The district provides NYSAA (New York State Alternate Assessment) support for students with significant cognitive disabilities who participate in the state's alternate assessment pathway.

A federal lawsuit, Vinluan v. Ardsley Union Free School District et al., involved allegations regarding IDEA and Section 504 practices. On July 27, 2021, a court granted a motion to dismiss in part and denied it in part, dismissing some claims while allowing others to proceed at that stage. No consent decree was identified in the documents reviewed.

English Learners

NYSED reported 39 English-language learners in Ardsley UFSD in 2024-25, representing approximately 2% of enrollment. The district provides English as a New Language (ENL) programming, which focuses on English language acquisition through content-area support. No dual-language or bilingual program was identified in the documents reviewed. ENL services are determined by each student's proficiency level, with students integrated into mainstream instruction to varying degrees depending on their language development needs.

Pre-Kindergarten

Ardsley does not operate a universal pre-kindergarten program. No district UPK seats, lottery, capacity figures, or waitlists were published in the documents reviewed. Families seeking pre-K options would need to look to private providers or neighboring districts.

Career and Technical Education

The district offers career and technical education through multiple pathways. Through Southern Westchester BOCES Career Services, students can access CTE programs across multiple industry fields. BOCES, or Boards of Cooperative Educational Services, are regional educational services agencies in New York that provide specialized programs individual districts may not offer on their own. Students attend specialized programs at BOCES facilities while remaining enrolled at Ardsley High School. Within the district, Ardsley High offers a Project Lead The Way engineering sequence, a nationally recognized curriculum that progresses through foundational and specialized engineering courses. A Senior Externship program provides a capstone field experience, allowing students to explore career interests through direct workplace exposure.

Athletics and Arts

Ardsley High School maintains a Wellness Center and fitness center, and the district operates a Rec-Pool that supports both physical education and community programming. Athletic offerings include traditional interscholastic sports, with the Panther Pep Band performing at home football games.

In the visual and performing arts, the district supports a Drama Club that produces a fall play and a spring musical. Music offerings include Select Chorus Honors, Chamber Orchestra Honors, Wind Ensemble Honors, and Jazz Ensemble, providing performance pathways for students at advanced levels. These ensembles represent the upper tier of the district's music program.

Transportation and Bell Times

Transportation eligibility requires students to meet district minimum-mileage requirements. Resident pupils attending nonpublic schools are eligible for transportation only if the school is located no more than 15 miles from the student's home. During the opening weeks of the school year, the district advises that buses may run 10 to 30 minutes late, and afternoon return times vary with traffic and dismissal patterns.

Bell times for 2025-26 differ across the three schools. Concord Road Elementary operates from 8:35 a.m. to 3:04 p.m. on Monday, Tuesday, Thursday, and Friday, with an early dismissal at 2:24 p.m. on Wednesdays. Ardsley Middle School runs from 7:50 a.m. to 2:40 p.m. on regular days, with a 2:00 p.m. dismissal on Wednesdays. Ardsley High School operates Monday through Thursday from 7:55 a.m. to 2:52 p.m. On Fridays, classes begin at 9:05 a.m. and end at 2:52 p.m., with a Music Hour at 8:10 a.m. that precedes the later academic start. The Wednesday early-dismissal pattern at the elementary and middle schools, combined with the Friday late-start at the high school, creates a weekly schedule that varies by day and by school. Families with children across multiple buildings will need to coordinate around three different dismissal windows on any given day.

Class Size

The district's class-size policy sets maximum ranges: kindergarten at 19 without aides and 22 with aides; grades 1-4 at 23; grades 5-8 at 24; and grades 9-12 at 26. District ideals are lower: kindergarten at 18, grade 1 at 19, grade 2 at 20, grade 3 at 21, grades 4-8 at 22, high school English at 18, and secondary world language, math, science, and social studies at 20. As of January 30, 2026, the district reports published elementary averages for 2025-26 of: kindergarten 18, grade 1 at 19, grade 2 at 22, grade 3 at 22, and grade 4 at 23. The district presents these figures alongside its policy maximums and stated ideals in budget workshop materials.

Before and After School Care

Three providers serve Ardsley families. The CRS After School Program, operated by the district, runs recreational sessions in Fall, Winter, and Spring, with eight classes per session. The Ardsley Children's Center provides after-school care for district children ages 5 to 12. Ardsley Pals serves students in grades 5 and 6 from dismissal until 6:15 p.m., with pickup options at 5:00 p.m. or 6:15 p.m. None of the providers reviewed published current fee tables or explicit capacity and waitlist policies on their public pages, so families would need to contact providers directly for cost and availability information.

Calendar

The 2026-27 school calendar sets the first student day as September 2, 2026, and the last student day as June 25, 2027. The district does not operate on a four-day school week schedule.

Safety, climate, and community

Official incident reporting

The New York State Education Department collects school safety incident data through its School Safety and the Educational Climate (SSEC) reporting system. For the 2024-25 school year, Ardsley's three schools reported the following: Ardsley High School recorded one "Minor Altercation" incident, Ardsley Middle School recorded one "Minor Altercation" incident, and Concord Road Elementary School reported zero incidents, according to NYSED's SSEC incident data.

The SSEC system counts incidents that schools self-report under categories defined in NYSED's SSEC glossary. A precise current definition for "Minor Altercations" was not located in the reviewed glossary pages. Because SSEC figures are raw incident counts rather than per-student rates, and because they depend on each district's own classification and reporting, they function as a year-to-year baseline within a building rather than as a standalone safety measure. A school reporting one incident and a school reporting zero in a given year may not differ in any statistically meaningful way; the counts are too small to support comparative conclusions across schools or districts.

Federal civil rights data on suspensions

The U.S. Department of Education's Civil Rights Data Collection (CRDC) for the 2021-22 school year provides suspension data disaggregated by race and sex for students without disabilities. Ardsley reported zero in-school suspensions across all demographic categories that year.

For single out-of-school suspensions, the district reported 21 incidents involving male students: 13 White, 4 Asian, 2 Hispanic, and 2 Black. No female students received single out-of-school suspensions in any category. For multiple out-of-school suspensions, the district reported 8 incidents involving male students: 3 White, 3 Hispanic, 1 Asian, and 1 of two or more races. No female students appeared in any multiple-suspension category either. These counts cover students without disabilities only; the CRDC tracks students with disabilities in separate categories not included in this dataset.

The complete absence of female students from every suspension category and the concentration among male students is a pattern visible in the raw numbers. The CRDC provides no context for individual incidents, and the counts alone do not indicate whether the pattern reflects differences in behavior, differences in reporting, or differences in how discipline is applied. The data establishes what was recorded; it does not explain why.

Discipline policy and building security

The district's 2025-26 Code of Conduct sets behavioral expectations and a range of consequences for student conduct and affirms a school environment free of harassment, bullying, and discrimination. The district-wide safety plan for 2025-26 indicates that building access is monitored by greeters and security monitors. No documentation confirming the presence or assignment of a school resource officer was found in the available materials, and the safety plan does not reference SRO staffing.

Cell phone policy and the state mandate

New York's FY2026 budget established a statewide distraction-free schools requirement that restricts student use of personal internet-connected devices during the school day, according to state implementation resources. Ardsley implements this requirement through Board Policy 7316, which governs student use of personal technology during both instructional and non-instructional times. At Ardsley Middle School, the posted rule requires personal devices to remain off and out of sight during school hours, including in hallways and common areas, and encourages students to leave them at home.

Climate survey

The district administered the Panorama Student Survey and presented an executive briefing on November 12, 2024. According to the published briefing, reported favorability for Sense of Belonging was 47 percent. Additional measures were summarized in the briefing but not separately published in the available materials. The Panorama instrument captures student self-reported perceptions, and the 47 percent figure represents the share of respondents indicating favorable responses on that specific construct.

Reported dispute over bullying response

A family formally reported an incident of peer bullying on October 27, 2025, and subsequently disputed the district's handling of the report. According to Patch news coverage, district communications noted that interviews were conducted and stated the matter was under review. CBS News reporting similarly characterized the district as emphasizing that it does not tolerate bullying. As of the latest cited reporting on November 19, 2025, the matter remained open. The family and the district differed on whether the district's response was adequate. No court ruling, settlement, or formal resolution was identified in the available materials.

Leadership, governance, and labor

The Ardsley Union Free School District (NCES LEA ID 3603180) serves approximately 2,324 students in Westchester County, New York. The district is governed by a five-member Board of Education and administered by a superintendent-led cabinet. Its official website is ardsleyschools.org.

Superintendent

Dr. Matthew Block has served as Superintendent of Schools since July 1, 2024. He previously served as Superintendent of Livingston Public Schools in New Jersey. His appointment was reported by local news outlets in April 2024.

Local news reporting dated June 22, 2026 indicated that the Board of Education intended to extend Dr. Block's contract through the 2030-31 school year at an upcoming meeting. No official confirmation of that extension has been located in the sources reviewed here, and the extension should be treated as reported but not yet confirmed by the district.

Superintendent turnover

The district has had three superintendents over the past decade. Dr. Lauren Allan served until her retirement on June 30, 2018. Dr. Ryan Schoenfeld succeeded her on July 1, 2018 and served until his retirement on June 30, 2024. Dr. Block began his tenure on July 1, 2024. Both prior departures were retirements. The turnover count across the decade is three superintendents, with two transitions occurring at six-year intervals. Superintendent turnover is a leading indicator of organizational stability; in this district, the pattern has been one of multi-year tenures with orderly transitions rather than abrupt mid-contract departures. Dr. Block is in the second year of his appointment, and the reported intent to extend his contract through 2031, if confirmed, would provide additional continuity.

Board of Education

The current Board of Education consists of five members:

  • Hrishi Karthikeyan serves as President of the Board of Education.
  • Bart Grachan serves as Vice President.
  • Vikas Agrawal, Mitchell Kleinman, and Joseph Sayegh serve as Trustees.

Board elections have been held annually, with votes recorded on May 17, 2022; May 16, 2023; May 21, 2024; May 20, 2025; and May 19, 2026. In New York, annual school budget votes and board member elections typically occur on the same day. For the 2026 vote, the district reported unofficial results of 803 yes votes (73 percent) to 297 no votes (27 percent) on the 2026-27 school budget, for a total of 1,100 ballots cast. Turnout figures specific to board member races have not been located in the sources reviewed here.

District cabinet

The district's officially listed leadership team includes:

  • Dr. Matthew Block serves as Superintendent of Schools.
  • Dr. Jennifer Bradshaw serves as Assistant Superintendent for Curriculum and Instruction.
  • Dr. Cheri Rosenblatt serves as Assistant Superintendent for Business, Facilities, and Operations.
  • Susan Seda serves as Assistant Superintendent for Pupil Personnel Services and Special Education.
  • Marianna Dougherty serves as Director of Special Education.
  • Matthew Pringle serves as Director of Athletics and Physical Education.
  • Sabrina Rich serves as Director of Technology.
  • Joseph Urbanowicz serves as Director of Facilities and Transportation.

Labor relations

The district's primary bargaining unit is the Ardsley Congress of Teachers (ACT), Local 1768, affiliated with NYSUT and AFT. The unit represents approximately 350 members. The district's current negotiation status is officially confirmed as active. Specific contract expiry dates have not been located in the sources reviewed here. No work stoppages have been identified in the available materials.

State fiscal monitoring

The New York State Office of the Comptroller (OSC) operates a Fiscal Stress Monitoring System that evaluates school districts on indicators including fund balance, cash position, and short-term debt. The system assigns a fiscal score and, where thresholds are met, a designation of Significant Fiscal Stress, Moderate Fiscal Stress, or Susceptible to Fiscal Stress. A higher fiscal score indicates greater stress.

Ardsley's trajectory through this system over the past three years is as follows. In 2023, OSC designated the district as being in Moderate Fiscal Stress, with a fiscal score of 51.7. In 2024, the district remained in Moderate Fiscal Stress, with its fiscal score increasing to 61.7. On June 21, 2024, OSC issued audit report 2024M-13, which found that the Board and district officials had not effectively managed fund balance and reserves. District officials indicated that corrective actions were underway or planned at the time of the audit. The audit finding that the Board had not effectively managed fund balance and reserves constitutes a documented governance conflict signal, as it identifies a gap between the Board's fiscal oversight responsibilities and its actual practices as observed by the state's audit authority.

In 2025, OSC assigned the district No Designation, with a fiscal score of 0. This indicates that, under the monitoring system's methodology, the district no longer met the thresholds for any fiscal stress category. No state monitor has been identified for the district, and the 2025 OSC file lists the district with No Designation. The transition from a fiscal score of 61.7 in 2024 to a score of 0 in 2025 represents a change in the district's standing under the OSC framework. The specific corrective measures taken by the district have not been detailed in the sources reviewed here.

Material litigation

The district has been named as a defendant in litigation in both federal and state courts. A federal court docket under the name Vinluan v. Ardsley Union Free School District is publicly accessible. Additional federal court filings appear in the U.S. District Court for the Southern District of New York under separate case numbers, and in the U.S. District Court for the Eastern District of New York. A case in the New York Supreme Court is also referenced in public legal databases. A law firm's website describes obtaining a reversal of a trial court's dismissal in a matter involving the district.

News outlets including Patch and CBS News New York have reported on complaints related to the district's handling of matters involving special education students. The specific claims, current status, and outcomes of these matters are not fully detailed in the sources reviewed here. Pending allegations are not findings and must be treated as such.

Risks and watch items: the forward calendar

Annual budget vote and board election

The next annual school-budget vote and Board of Education election is scheduled for May 18, 2027. Voters in Ardsley will decide on the district's 2027-28 budget and any open board seats. The most recent vote, held on May 19, 2026, resulted in approval of the 2026-27 budget with 803 yes votes (73 percent) and 297 no votes (27 percent), according to unofficial results posted by the district. The total of 1,100 ballots cast provides a reference point for expected turnout.

Superintendent contract extension

Local news reporting dated June 22, 2026 indicated that the Board of Education intended to extend Superintendent Dr. Matthew Block's contract through the 2030-31 school year at an upcoming meeting. No official confirmation of the extension has been located in the sources reviewed here. The specific date of the board meeting at which the extension was expected to be considered has not been confirmed. If approved, the extension would provide contractual continuity through the end of the 2030-31 school year.

Capital improvement program

The district broke ground on a $50 million capital improvement initiative on May 12, 2025. The program spans all district buildings and includes athletic field and facility upgrades. As a multi-year construction program, the project will continue through subsequent budget cycles. Specific completion dates for individual project phases have not been located in the sources reviewed here. Capital projects of this scale typically involve multi-year construction timelines, periodic change orders, and ongoing financial monitoring, all of which can affect future budget deliberations and facility availability.

High school schedule change

Ardsley High School held a community forum on January 27, 2026 to outline a rotating-drop schedule for the 2026-27 school year. The schedule extends class periods from 44 to 57 minutes and increases overall instructional time. Implementation is scheduled for the 2026-27 academic year. Schedule changes of this nature affect teacher planning time, student course loads, and daily building logistics, and their effects on student outcomes are typically assessed over multiple years.

Labor negotiations

The district's current negotiation status with the Ardsley Congress of Teachers (ACT), Local 1768 (NYSUT/AFT), is officially confirmed as active. The unit represents approximately 350 members. Specific contract expiry dates and negotiation timelines have not been located in the sources reviewed here. Active negotiations warrant monitoring because unresolved labor contracts can affect budget planning, staff retention, and instructional continuity.

Fiscal stress monitoring

The OSC Fiscal Stress Monitoring System evaluates school districts annually. The district received No Designation in 2025 with a fiscal score of 0, following two consecutive years of Moderate Fiscal Stress designations in 2023 (score 51.7) and 2024 (score 61.7). The next annual OSC fiscal stress assessment is expected but the specific release date has not been scheduled. The 2024 OSC audit (report 2024M-13) found that the Board and officials had not effectively managed fund balance and reserves, and officials indicated corrective actions were underway or planned. The effectiveness of those corrective actions will be reflected in future OSC assessments.

District-wide safety plan

The district issued a legal notice for a public hearing on the 2026-27 District-wide Safety Plan, scheduled for June 1, 2026, with proposed changes posted for public review. The next annual safety plan update is expected in 2027 but the specific hearing date has not been scheduled.

Surprising insights

Several findings in this report run counter to what a prospective resident might assume about how school assignment, capacity, and academic data work in a small Westchester district.

A property's municipal address in Greenburgh or Dobbs Ferry does not by itself determine which school district serves it. The town of Greenburgh contains multiple school districts, and the village of Dobbs Ferry is split between Ardsley Union Free School District and Dobbs Ferry Union Free School District. A buyer who assumes that a Greenburgh address or a Dobbs Ferry address maps to a particular district would be mistaken. The district boundary, not the municipal boundary, governs assignment, and the two do not always align. Families should verify the specific district assignment for any given property rather than relying on municipal labels alone.

A municipal boundary change, such as a village annexation or incorporation, does not move school district lines. Under New York Education Law Sections 1507 and 1508, changing which school district serves a given piece of territory requires a separate alteration order administered by the Commissioner of Education. This means that even if a village expands its borders, the school district boundary remains fixed until a formal legal process under the Education Law is completed. This separation of municipal and school district boundaries is a structural feature of New York governance that can create lasting misalignment between where a property sits politically and which schools serve it.

The district has no published building-by-building capacity utilization study. Without such a study, there is no district-acknowledged benchmark against which to measure whether Concord Road Elementary, Ardsley Middle School, or Ardsley High School is approaching its functional limit. A buyer cannot independently determine whether a particular building is at 70 percent or 95 percent of capacity, because the district has not published the denominator. The $50 million capital improvement project indicates investment in facilities, but capital investment can address deferred maintenance, code compliance, accessibility, or infrastructure renewal without signaling enrollment pressure in either direction.

The assessment data on file for this district consists exclusively of Advanced Placement exam proficiency rates. No Regents exam results, no grades 3-8 English language arts or mathematics assessment results, and no state accountability test scores appear in the computed data. This means the available academic evidence describes outcomes for a self-selected subset of students who took AP exams, not the full student body. A family evaluating this district should understand that the AP data captures the advanced coursework subset, not a representative cross-section of all enrolled students.

The graduation data on file is from the 2019-20 school year. This is the most recent graduation information available, and it predates the full effects of pandemic-era learning disruptions on subsequent graduation cohorts. The four-year adjusted cohort graduation rate for that year is reported as a suppressed range of 95 to 100 percent, based on a cohort of 162 students. No more recent graduation figure is available in the computed data.

Best fit: who this district serves well

This section describes educational and logistical needs that align with what Ardsley Union Free School District offers, and needs that the district does not currently meet based on the available evidence. It does not describe who a family is.

The district's structure provides small school scale and a predictable K-12 path. With 2,324 students enrolled in 2023-24 across three schools, and with only one school at each level, the district operates a compact, single-feeder system. A student who attends Concord Road Elementary proceeds to Ardsley Middle School and then to Ardsley High School without any possibility of reassignment to a different building within the district. There are no internal attendance lines to redraw, no feeder patterns to reshuffle, and no same-grade choice to navigate. For a family prioritizing assignment certainty, this structure eliminates a category of risk that exists in multi-school districts where boundary changes can reassign students to different buildings.

The district provides several advanced coursework pathways. The high school offers AP courses across multiple subjects, with 2023-24 proficiency rates reported in AP Biology, AP Calculus AB, AP Calculus BC, AP Chemistry, and AP Comparative Government and Politics. The district also offers Syracuse University Project Advance courses, which allow students to earn college credit through Syracuse University while remaining enrolled at Ardsley High School. A student who has exhausted standard high school mathematics may find AP Calculus BC and SUPA courses extend the academic ceiling. The Ardsley Science Research Program provides an additional pathway for students interested in scientific inquiry.

The district provides an accelerated mathematics track beginning at Ardsley Middle School. The middle school describes this track as moving at a faster pace than the standard curriculum, typically covering two years of content within a compressed timeframe. Entry into the accelerated sequence is determined by criteria the school establishes, and placement is not automatic. A family whose child is prepared for this pace should understand that the track exists as a distinct pathway and that the school applies specific criteria for entry.

The district has undertaken a $50 million capital improvement project, indicating ongoing investment in the physical plant across the three schools. A family concerned about the condition and modernization of school facilities can observe that the district is directing resources toward its buildings.

Several needs are not met by the district based on the available evidence. The district does not offer an International Baccalaureate program. No IB program is described in any available materials. A student seeking the IB Diploma Programme would need to look outside the district.

The district does not offer school choice within its boundaries. Because there is one school per level, a family cannot select among elementary or middle schools. A family seeking an alternative school environment, such as a magnet program or a choice-based assignment system, will not find one here.

The district does not publicly describe a standalone gifted identification process in the available materials. A family seeking a formal gifted program separate from the accelerated mathematics track and AP coursework should ask the district directly whether such a program exists, as the available evidence does not confirm one.

The computed data does not include free or reduced-price lunch counts, Individualized Education Program counts, or English learner counts. These figures are recorded as missing. This means the available data cannot speak to the size of special populations or the economic composition of the student body. A family needing to evaluate the district's capacity to serve specific educational needs should consult the district directly, as the computed profile does not contain this information.

The graduation data on file is from 2019-20 and is several years old. A family seeking current graduation outcomes should ask the district for more recent figures, as the computed data does not include them.

Questions parents should ask

The following questions arise from specific findings in this report. Each is grounded in a gap or limitation identified during the review of available materials.

What are the specific entry criteria for the accelerated mathematics track at Ardsley Middle School? The report found that placement is not automatic and that the mechanics of selection are not fully detailed in available materials. Ask the middle school counseling office or consult the middle school mathematics page.

Which AP courses will be offered in the upcoming school year, and how does availability depend on enrollment and staffing? The report found that course availability varies by year. Ask the high school guidance department and consult the program planning guide.

What is the current enrollment versus rated capacity at each of the three school buildings? The report found no published standalone utilization study. Ask the district business office.

What is the timeline for the $50 million capital improvement project, and which buildings will be affected? The report found evidence of capital investment but no published capacity study. Ask the district facilities department.

How do Syracuse University Project Advance credits transfer to colleges the student is considering? The report found that SUPA offers college credit but that credit-granting policies vary by institution. Ask the high school guidance department and review the SUPA courses page.

Scope, method, and sourcing notes

This report describes Ardsley Union Free School District using government data sources and publicly available district publications. It covers governance and geography, academic outcomes, school-level variation, advanced academics and pathway access, enrollment and capacity, and fiscal structure. It does not rate, rank, or recommend the district.

Enrollment data comes from the National Center for Education Statistics Common Core of Data for the 2023-24 school year. The district reported 2,324 students across three schools. Race and ethnicity counts are reported at the district level. Free and reduced-price lunch counts and rates are recorded as missing. Individualized Education Program counts and English learner counts are also recorded as missing. No school-level enrollment breakdown is available in the computed data.

Assessment data comes from New York state assessment records via a processed profile corpus. The data file contains 61 distinct series spanning 2006 through 2025, but the specific data points available are concentrated in the 2023-24 school year. These series track proficiency rates on Advanced Placement examinations only. No Regents exam results, no grades 3-8 English language arts or mathematics assessment results, and no state accountability test scores appear in the computed data. The AP data reports results for the "all students" group only. No subgroup breakdowns by race, ethnicity, economic status, disability status, or English learner status are available in the assessment series.

Graduation data comes from EDFacts ACGR via the Urban Institute Education Data API for the 2019-20 school year. This is the most recent graduation data available on file and is several years old. The four-year adjusted cohort graduation rate is reported as a suppressed range of 95 to 100 percent, based on a cohort of 162 students. No more recent graduation figure is available in the computed data.

Chronic absenteeism data comes from EDFacts Data Group 814 for the 2022-23 school year. The chronic absenteeism rate was 9.4 percent for all students in the district.

Finance data comes from the US Census Bureau Annual Survey of School System Finances (F-33) for fiscal year 2023. The revenue mix was 80.7 percent local, 17 percent state, and 2.3 percent federal.

Civil Rights Data Collection figures come from the US Department of Education for SY2021-22. These include AP enrollment counts by race and ethnicity, Algebra I enrollment data, suspension data, and gifted and talented enrollment data, aggregated across the district's three schools.

No long-run enrollment series was available on file. The single enrollment data point is from 2023-24. Without multiple years of comparable data, this report does not describe an enrollment trend.

No published standalone building utilization study was identified in a review of district facilities and operations materials. The district does not publish a building-by-building capacity report.

No child poverty data was available in the computed data. Free and reduced-price lunch data, which can serve as a proxy for economic disadvantage, is recorded as missing.

District publications, including the high school program planning guide, the high school profile, and the district website, were used for contextual information about academic programs, governance, and operations. Self-reported claims by the district are labeled as such in the text.
