State of the School District: Chappaqua, NY

Summary Perspective

Chappaqua Central School District is a sustainability story. The district operates as a self-contained K-12 system serving 3,578 students in 2023-24 across six schools, all open, with no feeder relationships sending or receiving students from other districts. Its fiscal structure relies on local property taxes for 88.4% of revenue in FY2023, a pattern consistent with New York's state aid formula directing comparatively modest sums to high-property-wealth districts. The district's adopted budget for 2026-27 is $150,125,516, growing from $138,296,286 in 2023-24, and the New York State Comptroller's fiscal stress monitoring system assigned a score of 6.7 in 2024, resulting in "No Designation." No active boundary study, redistricting process, school closure, or consolidation is on record through July 24, 2026.

The district's headline academic position is defined by Advanced Placement proficiency rates from 2023-24, the only assessment metric type available in the computed profile. These rates range from 80.0% in AP Computer Science A at grade 9 to 100.0% in AP Calculus BC at grades 11 and 12 and AP Chemistry at grade 11. The most recent graduation data on file is from 2019-20, with a cohort of 299 students, but the graduation rate itself was not provided in the computed data. No Regents exam results, state assessment proficiency rates, or subgroup breakdowns appear in the available assessment series. The district received a "Local Support and Improvement" accountability designation for 2025-26, meaning zero schools were identified for Comprehensive Support and Improvement, Targeted Support and Improvement, or Additional Targeted Support and Improvement.

The single most decision-relevant contextual fact is that the district operates one high school. Horace Greeley High School is the sole grades 9-12 building, which means every student who remains in the district through graduation attends the same school, is taught by the same faculty, and has access to the same course catalog. At the elementary and middle school levels, the district uses a neighborhood-zoned assignment model, but parcel-level boundary maps are not published on the district's website. The Registrar determines both elementary and middle school assignments for a given address, and no published guarantee ties a particular elementary attendance zone to a particular middle school. A family evaluating a specific property cannot independently verify school assignment from the district website alone and must provide the exact street address to the Registrar.

A 2021 capacity and enrollment analysis found available seats at all grade spans under its baseline method but projected that, under a higher-growth scenario, Douglas Grafflin Elementary School could exceed capacity in 6 to 9 years and Robert E. Bell Middle School in 12 to 13 years. These projections were made in early 2021, and no subsequent capacity study has been identified. The district's mathematics pathway places Algebra as the standard eighth-grade course for all students rather than an accelerated track, and the district does not operate a separate test-in gifted program, instead providing enrichment through a Multi-Tiered System of Supports framework. The LIFE School at Horace Greeley High School is an application-based program introducing the IB Career-related Programme for 2026-27.

This report describes what is true about the district rather than issuing ratings, rankings, or recommendations.

Key takeaways for families

• The district's AP proficiency rates for 2023-24 range from 80.0% to 100.0% across the subjects with reported data, but these rates reflect only the self-selected subset of students who took each exam, not the full enrollment of 3,578 students.
• No Regents exam data, state assessment proficiency rates, or subgroup assessment breakdowns appear in the computed profile, so the available academic evidence is limited to a single year of AP results from 2023-24.
• The most recent graduation data on file is from 2019-20, with a cohort of 299 students, but the graduation rate itself was not provided in the computed data.
• The district operates a neighborhood-zoned assignment model, but parcel-level boundary maps are not published on the district website, and the Registrar determines both elementary and middle school assignments for a given address.
• No published guarantee ties a particular elementary attendance zone to a particular middle school, meaning a family cannot assume middle school placement based on elementary zone alone.
• All six schools are open, and no active boundary study, redistricting, school closure, or consolidation is on record through July 24, 2026.
• A 2021 capacity analysis projected that under a higher-growth scenario, Douglas Grafflin Elementary could exceed capacity in 6 to 9 years and Robert E. Bell Middle School in 12 to 13 years, but no subsequent capacity study has been identified.
• The district's adopted budget for 2026-27 is $150,125,516, up from $138,296,286 in 2023-24, and the state Comptroller's fiscal stress monitoring system assigned a score of 6.7 in 2024, resulting in "No Designation."
• Local property taxes fund 88.4% of district revenue in FY2023, with state aid contributing 10.6% and federal sources 1%, reflecting the state aid formula's direction of comparatively modest sums to high-property-wealth districts.
• The New York property tax levy cap limits annual levy growth to the lesser of the consumer price index or 2 percent unless overridden by a 60 percent voter supermajority.
• The district serves the Village of Chappaqua, the Millwood hamlet, and parts of the Town of New Castle and Town of Mount Pleasant, but a resident's municipal address does not necessarily determine which school district serves their property because the district shares territory with other districts in two of those municipalities.
• The district does not operate a separate test-in gifted program and places Algebra as the standard eighth-grade course for all students, with enrichment provided through a Multi-Tiered System of Supports framework.

At a glance

The following table consolidates the key dimensions of Chappaqua Central School District into a single reference. Each row reflects the most recent data available in the computed profile or the body sections of this report. Where a data point is not available in the materials on file, the table states "Not available" rather than omitting the row or providing an estimate. Numeric figures come exclusively from the computed data.

The table above is intended as a quick-reference summary. Each entry is derived from and consistent with the detailed body sections of this report. The absence of a graduation rate, a state average for per-pupil spending comparison, and a market-level signal reflects gaps in the available data rather than a determination that these dimensions are unimportant. A family using this table should consult the corresponding body section for context on any row that bears on a specific decision.

How to read New York accountability

New York State's accountability system operates under the federal Every Student Succeeds Act (ESSA). The system includes several support model designations: Comprehensive Support and Improvement (CSI), Targeted Support and Improvement (TSI), and Additional Targeted Support and Improvement (ATSI). Schools and districts not identified for any of these support models receive a "Local Support and Improvement" designation, meaning monitoring and improvement activities occur at the local level rather than through state-mandated intervention. The New York State Education Department maintains public information on how these designations are assigned and what they require.

The Student Growth measure is one of the ESSA accountability indicators. This measure evaluates student progress over time relative to academic expectations, rather than measuring absolute achievement at a single point in time. For the 2025-26 accountability cycle, determinations were based on 2024-25 results and included the Student Growth measure as one of the indicators. The state released final accountability determinations for the 2025-26 cycle.

New York's property tax levy cap, established under General Municipal Law Section 3-c, limits annual school district levy growth to the lesser of the consumer price index or 2 percent. The New York State Comptroller's office has reported that the school district tax cap levy remains at 2 percent. A district may exceed this cap only if 60 percent of voters approve the budget at the annual May vote. If a proposed budget is defeated, the Board of Education must adopt a contingency budget under Education Law Section 2023, which restricts spending to ordinary contingent expenses, salaries and benefits required by law or contract, debt service, and previously authorized capital expenditures. The New York State School Boards Association provides a primer on how contingency budgets function under state law, including the specific categories of permissible spending and the caps that apply.

The body sections reviewed do not document any charter schools operating within this district. The district does not offer a general nonresident open-enrollment program or a general discretionary school-transfer program; Policy 5090 requires district residence for enrollment and permits only specified exceptions, including pending-residence admissions, limited continuation after moving out, certain employee children, and recognized international-exchange students.

For Chappaqua Central School District specifically, the 2025-26 accountability designation is "Local Support and Improvement," with zero schools identified for CSI, TSI, or ATSI, according to the state's accountability status data. The district's chronic absenteeism rate was 7.3% in the 2022-2023 school year. The district's adopted budget for 2026-27 represents a 3.97% year-over-year increase, operating within the levy cap framework. The district requires residency for enrollment and does not offer open enrollment or inter-district choice.

What kind of district this is: governance and geography

Chappaqua Central School District is a central school district organized under New York Education Law, Article 37, which governs the formation, alteration, and dissolution of central school districts in New York State. The National Center for Education Statistics classifies it as a regular local school district serving grades PK through 12. The district operates as an independent, unified K-12 system, meaning it provides the full continuum of public education from elementary through high school within a single district structure rather than relying on separate elementary and high school districts that feed into one another. The district's headquarters are in Chappaqua, New York, within the Town of New Castle in Westchester County. Enrollment in the 2023-24 school year was 3,578 students across six schools, all of which are currently open: Douglas G. Grafflin School, Horace Greeley High School, Roaring Brook School, Robert E. Bell School, Westorchard School, and Seven Bridges Middle School.

District type and feeder structure

Because Chappaqua CSD is a single K-12 district, it does not participate in a feeder system. It operates its own elementary schools serving grades K through 4, middle school serving grades 5 through 8, and Horace Greeley High School serving grades 9 through 12. The district does not tuition students to another district and has no sending or receiving feeder relationship with any other district. Students who begin their education in Chappaqua CSD elementary schools generally remain within the district through graduation, absent a family relocation or other transfer. The district also operates a Pre-K program, which is why NCES lists the grade span as PK-12 rather than K-12. The absence of a feeder arrangement means that the district's enrollment is self-contained: no other district sends students to Chappaqua CSD, and Chappaqua CSD does not send its students elsewhere for any grade level.

Taxing authority and budget approval

The Chappaqua Central School District Board of Education adopts the annual school budget at the May vote, after which it files a school tax warrant with the County of Westchester specifying the amount to be raised by school tax. Westchester County, through its tax collection machinery, extends the tax on the assessment roll and collects the school taxes. The school district itself levies the school tax, while the county serves as the collection agent. This division of responsibility is standard for school districts in Westchester County: the district sets the levy amount through its budget process, but the county government handles the mechanics of assessment, billing, and collection.

The annual school district vote takes place on the third Tuesday in May. Voters in the district approve or reject the proposed budget at that time. If the proposed budget is defeated, the Board of Education must adopt a contingency budget under New York Education Law Section 2023. A contingency budget may include only four categories of expenditure: ordinary contingent expenses such as utilities, insurance, legal and audit costs, and postage; teacher and employee salaries and fringe benefits required by law or contract; debt service and payments required by law or court order; and capital expenditures authorized by a prior voter-approved proposition. The administrative component of a contingency budget is capped at the prior year's amount adjusted by the lesser of the consumer price index or 2 percent. Capital items included in the defeated budget are removed, and voter-authorized propositions are funded only if they were previously and separately approved. The New York State School Boards Association provides a primer on how contingency budgets function under state law, including the specific categories of permissible spending and the caps that apply.

The Board of Education may put a revised budget to a second vote if the initial budget is defeated. If the second vote also fails, the district operates under the contingency budget framework described above for the entirety of the coming fiscal year. The district also remains subject to the New York property-tax levy cap under General Municipal Law Section 3-c, which limits annual levy growth to the lesser of the consumer price index or 2 percent unless overridden by a 60 percent voter supermajority. The New York State Comptroller's office has reported that the school district tax cap levy remains at 2 percent. This cap operates independently of the contingency budget process: even a voter-approved budget cannot exceed the levy cap unless the supermajority threshold is met.

Board of Education composition and elections

The Chappaqua CSD Board of Education consists of five members elected at large to three-year terms. Elections are held as part of the annual school district vote in May. Because members are elected at large, each member represents the entire district rather than a specific geographic sub-area or ward within the district's boundaries. The next scheduled election is May 18, 2027. The board's governance structure is standard for New York central school districts: no state takeover, receivership, mayoral control, or other non-standard governance arrangement is in effect. The New York State Education Department maintains a public list of districts and schools under receivership, and Chappaqua CSD does not appear on it.

Municipalities served and shared boundaries

The district's boundary encompasses territory in multiple municipalities, and in two of those municipalities the district shares territory with other school districts. Chappaqua CSD serves the entirety of the Village of Chappaqua and the entirety of the Millwood hamlet, also designated as a census-designated place. It also serves part of the Town of New Castle, which is also served by the Byram Hills Central School District, and part of the Town of Mount Pleasant, which is also served by the Pleasantville Union Free School District, the Ossining Union Free School District, and the Pocantico Hills Central School District. This means that a resident's municipal address does not necessarily determine which school district serves their property. Two homes in the same town, on the same street, could be served by different school districts depending on where the district boundary falls. Families evaluating properties in these shared municipalities should confirm district assignment for a specific address rather than relying on the municipal name alone.

Boundary change mechanism

Changing the Chappaqua Central School District's boundaries requires action by the New York State Commissioner of Education under Education Law Article 37, Sections 1801 through 1805. The typical process begins with a petition from qualified voters of an affected component or common school district, or from the district itself. This is followed by public hearings and a referendum in the affected territory, after which the Commissioner issues an order forming, altering, annexing territory to, or dissolving the district. Specific provisions governing the formation and alteration of central school districts are found in Section 1801 and Section 1802 of the Education Law.

Because the school district boundary is fixed by state Education Law and not by municipal lines, a change to a municipal boundary, such as the Village of Chappaqua, Town of New Castle, or Town of Mount Pleasant line, does not by itself change the school district's boundary. A separate Article 37 proceeding is required. This distinction matters for families evaluating properties near district borders: the school district that serves a given address is determined by the district boundary as established under Education Law, not by the municipal boundary shown on a town or village map. The district's official website provides information about registration and residency requirements for families seeking to confirm which district serves a specific address.

Academic outcomes: the evidence base

The computed assessment database for Chappaqua Central School District contains 82 series with a start year of 2006 and an end year of 2025, sourced from New York State assessment data. The database year index lists assessment years from 2006 through 2017. Of the 82 total series, 12 are available in the detailed computed profile, and each contains a single data point from the 2023-24 school year. All 12 series report Advanced Placement exam proficiency rates for the "all students" group. No other assessment metric types appear among the 12 detailed series provided.

AP proficiency rates, 2023-24

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

• In AP Biology, 93.3% of Grade 11 test-takers and 97.4% of Grade 12 test-takers achieved proficiency in 2023-24. The Grade 9 data point is missing.
• In AP Calculus AB, 95.3% of Grade 12 test-takers achieved proficiency in 2023-24. The Grade 11 data point is missing.
• In AP Calculus BC, 100.0% of Grade 11 test-takers and 100.0% of Grade 12 test-takers achieved proficiency in 2023-24.
• In AP Chemistry, 100.0% of Grade 11 test-takers achieved proficiency in 2023-24. The Grade 12 data point is missing.
• In AP Computer Science A, 80.0% of Grade 9 test-takers achieved proficiency in 2023-24.
• In AP Chinese Language and Culture, data is missing for both Grade 9 and Grade 11 in 2023-24.

Missing data points may indicate that no students in the specified grade took that exam, that the number of test-takers was too small to report under state privacy rules, or that the data was not submitted for that series. The computed data does not distinguish among these possible reasons.

Level and trajectory as separate questions

The level question asks how students performed in the most recent year for which data is available. The 2023-24 AP proficiency rates provide a snapshot of performance for the subset of students who took these exams. The reported rates range from 80.0% (AP Computer Science A, Grade 9) to 100.0% (AP Calculus BC in both Grade 11 and Grade 12, and AP Chemistry in Grade 11).

The trajectory question asks whether performance has changed over time. The computed profile does not support a trajectory analysis for these specific series. Each of the 12 detailed series contains only one data point, from 2023-24. While the database metadata indicates a broader collection of 82 series spanning 2006 to 2025, the specific data points available for this district's profile are limited to a single school year. A trajectory assessment would require multiple years of data for the same series, which are not present in the computed profile.

The database year index lists years from 2006 through 2017. The interval between 2017 and the 2023-24 data includes the 2019-20 school year, when New York State cancelled its standardized assessment administration due to the COVID-19 pandemic. The federal government waived testing requirements for that year, creating a discontinuity in the assessment record that affects every district in the state. This gap means that any multi-year analysis spanning the pandemic period would need to account for the missing 2020 data point.

Subgroup results

All 12 assessment series in the computed profile are reported for the "all students" group. No subgroup breakdowns by race, ethnicity, economic status, English learner status, or disability status are available in the assessment data on file. The enrollment data for the district provides race and ethnicity counts and rates for the overall enrollment, but these figures are not linked to assessment outcomes in the computed profile. Without subgroup assessment data, it is not possible to compare performance across student groups from the available data.

Graduation data

The most recent graduation data on file is from the 2019-20 school year, sourced from EDFacts Adjusted Cohort Graduation Rate data via the Urban Institute Education Data API. The cohort size for 2019-20 was 299 students. The graduation rate itself is not provided in the computed data. This data is several years old and reflects a cohort whose senior year spring was disrupted by the pandemic. The 2019-20 label must accompany any reference to this figure, as it does not represent current outcomes.

What AP proficiency measures and what it does not

Advanced Placement exams are designed to assess mastery of college-level curricular content in specific subjects. A proficiency rate reported for an AP exam represents the percentage of exam-takers who met the proficiency standard for that assessment as defined by the state's reporting framework. Several characteristics of AP data shape what these numbers can and cannot tell a reader.

AP participation is optional. Students who enroll in AP courses and take AP exams are a self-selected subset of the total student body. The district's total enrollment was 3,578 students in 2023-24, according to NCES Common Core of Data. The AP proficiency rates reflect only those students who chose to take each exam, not the performance of the full enrollment.

AP course offerings vary by school and by year. The subjects with reported data represent a subset of the AP courses the district may offer. Courses with missing data may not have been offered, may have had no exam-takers, or may have had results suppressed for privacy reasons.

AP proficiency does not measure grade-level mastery of state learning standards. New York State uses Regents examinations and other measures for that purpose under its accountability system. No Regents exam data appears in the computed assessment series for this district. A reader looking for evidence of district-wide academic performance against state standards would not find it in the AP data alone.

AP exams measure content knowledge in specific subjects. They do not measure writing across disciplines, critical thinking in non-tested subjects, social-emotional development, or post-secondary readiness in its broader sense. A district could have high AP proficiency rates and still have areas where student outcomes are not captured by this metric.

Accountability context

Under New York State's ESSA accountability system, Chappaqua Central School District received a designation of "Local Support and Improvement" for the 2025-26 school year. According to the New York State Education Department, this designation means the district and its schools are not identified for Comprehensive Support and Improvement (CSI), Additional Targeted Support and Improvement (ATSI), or Targeted Support and Improvement (TSI) support models. Monitoring and improvement activities occur at the local level. Zero schools in the district were identified for CSI, TSI, or ATSI support in 2025-26, according to the state's accountability status data.

The district's 2025-26 accountability determinations were based on 2024-25 results, which included a Student Growth measure as one of the ESSA accountability indicators. The state released final accountability determinations for the 2025-26 cycle. The district reports that it is committed to using data to inform decisions and to track the impact of these decisions over time, according to its strategic coherence plan.

The district's chronic absenteeism rate was 7.3% in the 2022-2023 school year, according to EDFacts Data Group 814. Chronic absenteeism is defined as missing 10% or more of enrolled school days for any reason. This rate applies to all students in the district.

Enrollment context

The district's enrollment for 2023-24 was 3,578 students, according to NCES Common Core of Data via the processed profile corpus. Race and ethnicity were reported as follows: 2,483 white students (69.4%), 564 Asian students (15.8%), 270 Hispanic students (7.5%), 213 students of two or more races (6.0%), 40 Black students (1.1%), 2 American Indian or Alaska Native students (0.06%), and 2 Native Hawaiian or Pacific Islander students (0.06%). Free or reduced-price lunch data, Individualized Education Program counts, and English learner counts were not reported in the computed enrollment profile.

Inside the district: variation between schools

The Chappaqua Central School District operates six schools, all with an open lifecycle status according to NCES CCD data. The six schools are Douglas G Grafflin School, Horace Greeley High School, Roaring Brook School, Robert E Bell School, Westorchard School, and Seven Bridges Middle School. Total district enrollment was 3,578 students in 2023-24.

A defining structural feature of this district is that it contains a single high school. Horace Greeley High School, as its name indicates, is the only school in the district serving upper secondary grades. This means that whatever variation may exist among the district's other school buildings, all students who remain in the district through graduation converge into a single high school. There is no second high school against which Horace Greeley's outcomes can be compared within the district boundary. Every student who attends a Chappaqua public high school attends Horace Greeley, is taught by the same faculty, and has access to the same course catalog and programs.

The advanced placement assessment data on file for this district is reported at the district level, not disaggregated by individual school. For the 2023-24 school year, the district's AP proficiency rates include 93.3% in AP Biology at grade 11, 97.4% in AP Biology at grade 12, 95.3% in AP Calculus AB at grade 12, 100.0% in AP Calculus BC at grade 11, 100.0% in AP Calculus BC at grade 12, 100.0% in AP Chemistry at grade 11, and 80.0% in AP Computer Science A at grade 9, according to state assessment data. Because these metrics are reported as district-level figures and the district operates only one high school, they effectively represent the performance of a single school's student body. The question of how much AP outcomes vary between high schools within this district has a structural answer: they do not vary, because there is only one high school.

At the elementary and middle school levels, the available data does not include school-by-school assessment breakdowns. The district operates five additional schools besides Horace Greeley High School: Seven Bridges Middle School, Robert E Bell School, Douglas G Grafflin School, Roaring Brook School, and Westorchard School. Seven Bridges is identified as a middle school by its name. The available computed data does not specify grade-level configurations for the remaining four schools. Regardless of how those grade bands are distributed, the assessment series on file do not separate results by individual building at these levels. A family therefore cannot use the available computed data to determine whether students at one school score differently on state assessments than students at another, or whether schools serving the same grade bands produce measurably different academic outcomes. This absence is a factual finding: the variation between schools at the pre-high-school level in this district cannot be characterized from the data currently available.

The district's enrollment and demographic data is similarly reported in aggregate. While the total enrollment of 3,578 students in 2023-24 is known, the computed data does not provide per-school enrollment counts. The racial and ethnic composition of the district's student body in 2023-24 was 69.4% white, 15.8% Asian, 7.5% Hispanic, 1.1% Black, 6.0% two or more races, and fewer than 1% each for American Indian or Alaska Native and Native Hawaiian or Pacific Islander. These figures cannot be broken down by individual school, so it is not possible to describe how demographic composition varies across the six buildings. Data on free and reduced-price lunch eligibility, Individualized Education Program participation, and English learner status are all reported as missing for this district, which further limits the ability to assess variation in student populations or needs across schools.

Horace Greeley High School was named a 2022 National Blue Ribbon School by the U.S. Department of Education, according to the New York State Education Department. This recognition applies to the high school specifically. The district also reported 12 National Merit Scholarship Program finalists for 2026, according to the district's own announcement. Both of these outcomes are attributable to the single high school and do not illuminate variation at lower grade levels.

The structural reality of this district is that variation between schools is most likely to exist at the elementary and middle school levels, where multiple buildings serve similar grade bands. However, the data available does not permit a factual comparison of outcomes across those buildings. At the high school level, variation between schools is nonexistent by structural design: there is one school, and all district students who continue through the upper grades attend it. The available data describes a district-wide profile rather than a school-by-school one, and the single-high-school structure means all students eventually share the same upper-grade experience regardless of which elementary or middle school they previously attended.

Advanced academics and pathway access

Grade 8 mathematics placement

Chappaqua structures its mathematics sequence so that Algebra is the standard eighth-grade course rather than an accelerated option reserved for a subset of students. The district's mathematics department page describes the pathway as "culminating in Algebra for all students in eighth grade." The 8th-grade Decisions course offerings list three eighth-grade math options, including Enriched Algebra. Placement into these options is described through the course offerings themselves rather than through a single published entrance examination or cutoff score. The district does not operate a standalone test gate for eighth-grade math; instead, placement is determined through the regular course-selection process informed by prior student performance data.

The US Department of Education's Civil Rights Data Collection for SY2021-22 captured Algebra I enrollment data across six school-level records in the district. The CRDC also collected gifted-and-talented enrollment data for the same year across the same six records. Neither dataset shows a separate districtwide test-in gifted program operating in Chappaqua.

Gifted identification

Chappaqua does not operate a separate, test-in gifted program. The district's approach to enrichment is described on its Multi-Tiered System of Supports page, which explains that enrichment is provided through MTSS based on student data. Under this model, rather than identifying a fixed cohort of gifted students through a one-time assessment, the district uses ongoing data review to determine which students need additional challenge or support at any given point. MTSS is a framework that tiers interventions: all students receive core instruction at Tier 1, some receive supplemental support or enrichment at Tier 2, and a smaller number receive intensive, individualized services at Tier 3. In Chappaqua's implementation, enrichment for advanced learners falls within this continuum rather than in a self-contained gifted classroom or pull-out program.

Selective program entry: LIFE School

Horace Greeley High School houses the LIFE School, an application-based program. According to the LIFE School page, students apply to participate in LIFE and complete coursework within the program's framework. The program operates within Horace Greeley High School rather than as a separate school with its own building. Students accepted into LIFE take their coursework through the program while remaining part of the broader Horace Greeley student body.

A Board of Education presentation on February 12, 2025 announced that LIFE will introduce the IB Career-related Programme. The LIFE School page, describing the 2026-27 program, states that students pursue the IB Career-related Program. This change was announced by the Chappaqua Central School District administration and the Chappaqua Board of Education, and its status is officially confirmed and implemented. No organized opposition to this change is documented in the available research.

Advanced Placement courses and enrollment

Horace Greeley High School offers Advanced Placement courses as listed in the 2026-27 Decisions catalog. According to the 2019 school profile (reporting 2018 data), the school reports 1,262 AP exams taken by 549 exam takers. These figures are self-reported by Horace Greeley High School.

The Civil Rights Data Collection for SY2021-22 provides a demographic breakdown of AP enrollment across six aggregated school-level records. The CRDC recorded the following AP enrollment by race and ethnicity: 368 White students (185 male, 183 female), 73 Asian students (30 male, 43 female), 31 Hispanic students (19 male, 12 female), 20 students of two or more races (8 male, 12 female), 2 Black students (0 male, 2 female), 0 American Indian or Alaska Native students, and 0 Native Hawaiian or Pacific Islander students. The CRDC also recorded 27 students with Individualized Education Programs (13 male, 14 female) and 66 students with Section 504 plans (37 male, 29 female) enrolled in AP courses. These are enrollment counts at a single point in time during the 2021-22 school year, not exam-taking counts.

International Baccalaureate

The IB Career-related Programme is available through the LIFE School at Horace Greeley High School. The IB Career-related Programme (CP) is one of four International Baccalaureate programmes; it is designed for students who wish to combine IB coursework with career-related studies. The district does not offer the IB Diploma Programme, which is a separate, more comprehensive two-year IB qualification. Because LIFE School is application-based, a student who wants to pursue IB coursework must first apply to and be accepted into the LIFE program.

The ceiling: college credit, research, and post-AP options

Beyond standard AP courses, the district offers several programs for students who have completed or wish to extend beyond the regular advanced curriculum. The Science Research Program is a three-year sequence that allows students to conduct original scientific research. AP Capstone, consisting of AP Seminar and AP Research, provides a two-year sequence focused on research methods, argumentation, and inquiry. In mathematics, the district lists Advanced Topics in College Mathematics as a post-AP offering.

For college credit, the district offers dual-enrollment arrangements through university partners. According to the course offerings, these partners include Syracuse University through its Project Advance program, the University at Albany (SUNY), Mercy College, and Westchester Community College. Under these arrangements, students take courses at Chappaqua that carry concurrent college credit from the partner institution. Students typically must meet the partner university's registration requirements and pay any associated fees to receive the college credit.

The district also reports student participation in external academic competitions. A district news post describes Horace Greeley students participating in the Regeneron WESEF science competition. A separate post provides an update on National Merit Scholarship Program recognition.

Detracking and pathway changes

The available research does not document a formal detracking initiative or a restructuring of honors-level courses in the district. No board proposal to eliminate honors designations or to merge course levels is documented in the materials reviewed. The pathway change on record is the introduction of the IB Career-related Programme at LIFE School, categorized in the available research as an acceleration expansion rather than a reduction or elimination of existing tracks. The actors are the Chappaqua Central School District administration and the Chappaqua Board of Education, and the change was announced at the February 12, 2025 board presentation. No positions in opposition to this change are documented in the available research.

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

How an address becomes a school seat

Chappaqua Central School District operates a neighborhood-zoned assignment model. A child must reside within the district, and the school served by that residence's attendance zone determines placement. The district's internal geography comprises three elementary attendance areas (Douglas Grafflin, Roaring Brook, and Westorchard, all serving grades K-4), two middle-school attendance areas (Robert E. Bell and Seven Bridges, both serving grades 5-8), and a single districtwide high school (Horace Greeley, serving grades 9-12). The district lists Horace Greeley as its sole grades 9-12 school, which means every district resident at the high school level attends the same building regardless of address.

A critical detail for a buyer is that parcel-level boundary maps are not published on the district's retrieved web pages. The district's Registrar confirms both district eligibility and the specific elementary and middle school assignment for a given address. Families cannot independently verify a precise address-to-school mapping from the district website alone; they must provide the exact street address to the Registrar, who determines the assignment. This means that two homes on the same street could, in principle, feed to different elementary or middle schools, and a buyer should not assume an assignment based on a neighbor's school.

Whether an elementary zone guarantees a specific middle school

No published guarantee tying a particular elementary attendance zone to a particular middle school was found in the district's official materials. The Registrar separately determines both the elementary and the middle school for an address. This is an important structural fact: a family cannot assume that because their address falls within, for example, the Grafflin elementary attendance area, their child will necessarily attend a specific middle school. The middle-school assignment is an independent determination made by the Registrar for each address. The high school assignment, by contrast, is uniform across the district because Horace Greeley is the sole secondary school.

Capacity pressure by building

The district commissioned a capacity and enrollment analysis presented in 2021. That report, dated February 25, 2021, found 325 available K-4 seats, 333 available grades 5-8 seats, and 304 available grades 9-12 seats under its functional-capacity method. At the time of the report, Horace Greeley High School showed an enrollment of 1,176 against a functional capacity of 1,480, leaving 304 seats, and the report projected sufficient capacity at Horace Greeley throughout the 15-year study period.

The report also modeled a higher-growth scenario, referred to as Scenario 2. Under that scenario, Douglas Grafflin Elementary School was projected to exceed capacity in 6 to 9 years, and Robert E. Bell Middle School was projected to exceed capacity in 12 to 13 years. Seven Bridges Middle School and Horace Greeley High School retained sufficient capacity through the full 15-year study period under that higher-growth scenario. These projections were made in early 2021 and were based on enrollment drivers the report identified, including natural change in the existing housing stock modeled through birth-rate patterns, housing "backfill" (families with school-age children replacing households without children), and proposed housing and land-use changes such as the Form Based Code and identified Chappaqua-area housing projects. The report also attributed an unusual 2020-21 kindergarten increase to COVID-19-era moving and relocation patterns and increased local real-estate sales.

A long-run enrollment series is not available on file, so it is not possible to describe a multi-year trend line from the data in hand. The 2021 report provides the most recent sourced directional statements about capacity and enrollment pressure available in the materials reviewed.

Active boundary or redistricting studies

No active boundary study, redistricting process, rezoning effort, school closure, consolidation, or moratorium was identified in official records reviewed through July 24, 2026. The district's complete official agendas-and-minutes archive for the period from July 24, 2024 through July 24, 2026 was checked using the concepts of attendance boundary, attendance zone, redistricting, rezoning, reconfiguration, school closure, consolidation, moratorium, new school, replacement school, and school opening. No items matching those concepts were found. The current Board of Education portal, meeting-agenda hub, district news and announcements, the adopted 2026-27 budget materials, the 2024-25 budget book, and the 2022 Facilities Improvements and School Safety Bond materials were also reviewed. Targeted official-site searches for boundary studies, rezoning, closures, consolidations, and new schools returned no results. The official agenda and minutes archive was also searched for permanent boundary changes and closures during the period from July 24, 2016 through July 24, 2026, and none were found.

The mechanism by which boundaries could change in Chappaqua is the standard one for New York public school districts: the Board of Education holds the authority to adjust attendance zones, and any such change would ordinarily appear in the board's public meeting agendas and minutes as a posted action item or discussion item. The district's meeting agenda archive is the primary public record where such activity would surface. A buyer monitoring for future boundary changes should watch that archive for agenda items referencing attendance zones, redistricting, or capacity studies. The 2021 capacity report's higher-growth scenario projections for Grafflin and Bell are the most specific sourced signal that capacity pressure could eventually prompt such a discussion, but no such discussion has been initiated as of the records reviewed.

Closure and consolidation exposure

No active closure or consolidation process was identified. No closure moratorium was found as of July 24, 2026. All six schools in the district's current NCES listing carry an "open" lifecycle status. The district has not announced or studied the closure or consolidation of any school building in the materials reviewed.

Grandfathering policy

The district's Policy 5090 on student residence governs what happens when a student moves to another attendance zone within the district. No boundary-redraw-specific grandfathering rule was found, because no boundary redraw has occurred. However, the policy does address the case of an in-district move: a student who moves to another attendance zone during a school year may finish that year at the original school. District transportation is not provided in that situation. Additionally, the Superintendent may permit a student with two or fewer academic years remaining at the original elementary or middle school to stay at that school, provided that no additional class section would be required as a result. This means that a family moving within the district has a defined but limited right to continuity at the current school, and the practical availability of that right depends on whether the school has an open section.

Transfer mechanics

No general discretionary school-transfer program was found. Policy 5090 does not provide a mechanism for families to request a different school within the district as a matter of preference. The only intra-district transfer-like process is the zone-stay provision described above, which applies after an in-district move and is subject to the Superintendent's approval and the no-additional-section condition.

For inter-district movement, no general nonresident open-enrollment program was found. Policy 5090 requires district residence and permits only specified exceptions, including pending-residence admissions, limited continuation after moving out, certain employee children, recognized international-exchange students, and limited Horace Greeley completion arrangements. The policy allows some tuition arrangements: students who move out after the school year begins may finish a semester with prorated tuition or a second semester for half the annual tuition, and students completing grades 9 through 11 may request to complete grade 12 at Horace Greeley as tuition-paying nonresidents, subject to hardship-waiver provisions. Tuition follows the New York State formula and is generally payable in advance.

Residency verification practice

The district enforces residency through a multi-document verification process. Policy 5090 requires three proofs: one primary proof (such as a deed or executed contract of sale, a tenant-and-landlord-signed lease, a notarized owner or landlord or tenant affidavit with deed or tax bill, or a third-party affidavit establishing physical presence) plus two documents issued within the last 30 days showing the address (such as a water or property-tax bill, non-cellular telephone bill, cable bill, gas or electric bill, homeowners or renters insurance, vehicle registration or insurance, or a valid driver or non-driver ID). Custody or guardianship documents are required where applicable. The district may require proof of residence throughout a student's entire district career and may determine residency status at any time. False written statements are prohibited under New York Penal Law section 210.45. A student determined to be a nonresident may be excluded, and the parent or guardian may be charged tuition from enrollment through exclusion plus collection costs. The student registration form also warns that the district may seek legal recourse, including judgment for nonresident tuition.

Pre-K as a separate entry point

For the 2026-27 school year, the district offered 108 Pre-K seats through a random drawing. Numbers drawn after the first 108 formed an ordered waitlist, and later openings were offered in lottery order. This is a separate process from the K-12 neighborhood-zoned assignment model and does not guarantee a subsequent kindergarten seat in a particular elementary attendance zone.

What is not known

No district analysis of where departing students enroll was found. The 2021 capacity and enrollment report mentions out-of-district placement only as a planning ratio, not as a destination or outflow study. No published outflow analysis exists. A long-run enrollment trend series is not available in the materials on file. The most recent sourced directional statements about enrollment and capacity come from the 2021 report, and no subsequent capacity study has been identified in the records reviewed through July 24, 2026.

Fiscal health and the tax picture

Per-pupil spending and revenue mix (FY2023)

According to the US Census Bureau Annual Survey of School System Finances (F-33) for FY2023, Chappaqua Central School District reported total revenue of $136,845,000 on a membership base of 3,574 students. Total expenditures were $133,185,000, and current spending, which excludes capital outlay and debt service, was $122,600,000. That yields a current per-pupil expenditure of $34,303. Spending on instruction per pupil was $21,234.

The revenue mix was 88.4% local ($120,919,000), 10.6% state ($14,542,000), and 1% federal ($1,384,000). This heavy reliance on local revenue is a structural feature of New York school finance. The state aid formula directs comparatively modest sums to districts with high property wealth, leaving local property taxes to fund the largest share of operations. The federal share, at 1%, is minimal and typically tied to specific categorical programs rather than general operations.

Adopted budget trajectory

The district's adopted budget for 2026-27 is $150,125,516, representing a 3.97% year-over-year increase, according to the district's budget book. Over four years, the adopted budget has grown from $138,296,286 in 2023-24 to $140,747,738 in 2024-25 (revised), $144,392,025 in 2025-26, and $150,125,516 in 2026-27.

Structural balance

The 2026-27 plan appropriates $2,300,000 of assigned fund balance and $350,000 from the debt service reserve to close the gap between planned spending and projected revenue, according to the district's budget book. Despite this planned draw, FY2025 operations generated a $2,029,894 General Fund surplus, according to the district's audit. The New York State Office of the Comptroller's 2024 fiscal stress monitoring system gave the district a score of 6.7, resulting in "No Designation," according to OSC's summary report. Scores below 25 receive no designation; the system draws on indicators such as fund balance as a percentage of revenue, operating deficits, and cash position to produce a composite score.

No multi-year operating projection was published in the 2026-27 budget book. The book does include a debt service schedule extending through 2040-41, with declining annual debt service in later years.

Federal pandemic relief

No district document located in this review identified recurring positions supported by ESSER or ARP federal pandemic relief funds, or stated what was cut, backfilled, or absorbed when that aid ended. The 2026-27 adopted budget is silent on ESSER/ARP. The absence of documentation means the district's post-pandemic fiscal transition cannot be traced through publicly available budget materials reviewed here.

Reserves

The unassigned General Fund balance was $5,768,001 as of June 30, 2025, equal to 3.99% of the ensuing 2025-26 budget, according to the district's audit. New York State law caps unassigned General Fund balance at 4% of the ensuing year's budget, excluding amounts assigned to the subsequent budget. The district is at the statutory ceiling.

The unassigned balance has increased across three consecutive audits: $5,398,037 at June 30, 2023; $5,604,175 at June 30, 2024; and $5,768,001 at June 30, 2025. The total General Fund balance, which includes assigned, restricted, and committed portions, rose from $17,829,165 to $19,446,665 to $21,476,559 over the same period.

Long-term obligations

As of June 30, 2025, the district had $76,711,884 in outstanding debt, according to the district's audit. FY2025 General Fund debt service was $6,784,299, consisting of $4,962,338 in principal and $1,821,961 in interest. The 2026-27 budget schedules $10,025,716 of debt service, an increase reflecting bonds issued under the 2022 capital authorization.

The district also reported post-employment obligations as of June 30, 2025: a $3,878,941 net pension liability under the New York State and Local Employees' Retirement System, an $8,894,879 net pension asset under the New York State Teachers' Retirement System, and a $234,460,859 total OPEB liability for its single-employer retiree-health plan, according to the district's audit. The OPEB liability represents the present value of promised retiree health benefits. Unlike pension obligations, which are backed by state retirement systems with dedicated revenue streams, OPEB liabilities are typically funded from future operating budgets.

Credit rating

Moody's assigned a AAA rating to the district, according to the district's external auditor presentation. The rating action was listed as "new." A AAA rating is the highest category on Moody's scale and generally corresponds to lower borrowing costs on bond issuances.

Tax levy limit and override history

For 2026-27, the district calculated a tax levy limit of $129,426,852, which includes $6,352,200 of permissible exclusions for capital expenditures and pension cost growth, according to the district's budget book. The adopted levy of $128,280,312 is $1,146,540 below this limit. The levy increase is 2.99%, so a 60% supermajority override was not required. The district also confirmed that tax levy recapture does not apply for 2026-27. Recapture is a mechanism by which the state claws back excess tax revenue from districts whose property wealth per pupil exceeds a statutory threshold.

New York's tax cap law limits annual growth in a district's tax levy to the lesser of 2% or the rate of inflation, with exclusions for certain capital and pension costs. A district may exceed the calculated limit only with 60% voter approval. Chappaqua has remained within the cap in every year except one attempt.

In 2024, the district's initial budget proposal of $141,856,238 required a 60% override and was defeated by 878 votes (1,128 yes to 2,006 no), according to The Examiner News. The district subsequently proposed a revised budget of $140,747,738 that stayed within the cap, which passed by 953 votes (1,234 yes to 281 no), according to lohud.

How a household tax bill connects to the district levy

The district's tax levy is the total amount raised from property taxes to fund operations. This levy is apportioned between the two towns the district serves, New Castle and Mount Pleasant, based on each town's share of total equalized property value within the district boundaries. Each town then divides its apportionment by its total taxable assessed value to produce a tax rate per $1,000 of assessed value. A household's school tax bill equals the assessed value of its property, divided by 1,000, multiplied by that rate.

For 2026-27, the district estimates rates of $124.86 per $1,000 of assessed value in New Castle and $1,627.79 per $1,000 in Mount Pleasant, according to the district's budget book. The large disparity between the two rates reflects differences in how each town assesses property, not differences in the total levy assigned to each town. A town that assesses property at a lower percentage of market value will have a higher rate per $1,000 of assessed value to raise the same revenue from comparable properties. The county finalizes rates after applying equalization factors.

The county's final 2025-26 rates were $122.379959 per $1,000 in New Castle and $1,608.239212 per $1,000 in Mount Pleasant, according to Westchester County. New Castle's rate has risen each year from $115.96 in 2022-23 to $118.28, $121.19, $122.38 in 2025-26, and an estimated $124.86 in 2026-27. The total levy increased from $119,574,460 in 2023-24 to $121,738,983, $124,550,099, and $128,280,312 in 2026-27.

For context, neighboring districts' 2025-26 rates in New Castle were: Pleasantville UFSD at $123.02 per $1,000, Byram Hills CSD at $98.94, and Bedford CSD at $95.66, according to Westchester County.

Capital bonds and voter measures

The district has passed two capital bonds in the past decade. In 2016, voters approved a $42,500,000 capital bond by 528 votes (1,380 yes to 852 no), according to lohud. In 2022, voters approved a $33,985,000 facilities-improvements and school-safety capital bond, according to Patch. As of June 30, 2025, $14,888,426 remained unspent on the 2022 authorization, according to the district's audit.

An August 2022 building condition survey identified approximately $40.9 million of capital needs, comprising roughly $24.5 million in Category A infrastructure and life-safety items and $16.4 million in Category B special projects, according to the district's presentation. The $33,985,000 bond addressed a portion of these identified needs.

Annual budget votes have generally passed. The 2023 budget of $138,296,286 passed, according to Patch. The 2025 budget of $144,392,025 passed by 899 votes (1,274 yes to 375 no), according to ParentSquare. The 2026 budget of $150,125,516 passed by 480 votes (693 yes to 213 no), according to Patch. In 2026, voters also approved a capital-reserve proposition by 693 votes (795 yes to 102 no), according to the district's Facebook page.

The municipal and land-use context

The Chappaqua Central School District operates across territory in the Town of New Castle and the Town of Mount Pleasant in Westchester County. Its budget is adopted by the Board of Education and decided by district voters in an annual vote; no municipal body, whether town, city, or county, approves or vetoes the CCSD budget. Towns issue tax bills to property owners within the district, but the tax levy is set through the school district's own budget process, not through municipal fiscal decisions. New York State's Fiscal Stress Monitoring System, administered by the Office of the State Comptroller, monitors municipal fiscal stress annually, but this mechanism applies to municipalities and does not create a transmission path from town fiscal health to school budget adoption. The district's budget page and Board of Education resource manager reflect the standard budget adoption and voter approval process. The League of Women Voters voter information page confirms the district budget vote as a separate ballot item.

Proposed Village of Edgemont incorporation

The most active municipal restructuring matter in the region is the proposed incorporation of the Village of Edgemont, located in the Town of Greenburgh. This matter does not alter CCSD's territory, tax base, enrollment, or governance. The Edgemont Incorporation Committee filed its third incorporation petition under Village Law Article 2 with the Greenburgh Town Clerk on July 15, 2024. A public hearing and objections followed on September 18, 2024. On September 27, 2024, Greenburgh Town Supervisor Paul Feiner determined the petition legally insufficient. Petitioners then commenced a CPLR Article 78 proceeding on October 25, 2024. On March 6, 2026, the Supreme Court annulled the Supervisor's determination and ordered steps toward an election within 40 days. On March 11, 2026, the Town of Greenburgh announced it would appeal. The incorporation petition and related documents are posted on the Town of Greenburgh's incorporation information page. The Supreme Court's decision and order is a public document.

The actors in this matter include the Edgemont Incorporation Committee, the Town of Greenburgh, Greenburgh Town Supervisor Paul Feiner, the Greenburgh Town Board, the City of Yonkers as a proposed respondent-intervenor, the New York State Department of State, and the Center for Governmental Research (CGR), which produced a state-sponsored fiscal impact study.

The fiscal positions of the parties differ sharply. The Greenburgh Town Board projects a $4.2 million net operating-fund loss, an additional $500,000 town-wide loss, and termination of 25 to 30 full-time employees. The CGR study models tax outcomes under several scenarios and cautions that actual decisions and negotiations could differ from any single model. The Edgemont Incorporation Committee asserts that a new village could maintain services at approximately current taxation through intergovernmental cooperation.

The relevance of this matter to CCSD is geographic context only. The petition concerns territory in Greenburgh associated with Edgemont and does not name or alter CCSD's New Castle and Mount Pleasant territory, tax base, enrollment, or governance. CCSD's boundaries are not at issue in the incorporation proceeding.

Westchester County fair-and-affordable-housing settlement and Chappaqua Crossing

In 2009, Westchester County entered into a federal fair-and-affordable-housing settlement requiring the development of 750 affordable housing units over seven years. The Department of Justice filing documents the terms. The county reports that a court-appointed monitor found substantial compliance in 2021, though the record does not reflect a formal court termination of the settlement. The Westchester County Board of Legislators states that legal requirements have been met and the commitment to affordable housing continues.

County listings identify affordable housing units at Chappaqua Crossing as located within the Chappaqua Central School District. The county's Chappaqua Crossing workforce housing page and a county document recording New Castle's response are public record. Official sources do not state any enrollment or school-tax impacts for CCSD resulting from these units. No student counts, tax projections, or district-specific fiscal analyses appear in the available public record from these sources.

What municipal changes would affect CCSD

CCSD's budget process is self-contained at the district level. The Board of Education adopts a proposed budget, district residents vote on it in an annual election, and the approved levy is collected through tax bills issued by the towns of New Castle and Mount Pleasant. Municipal fiscal stress in either town does not directly alter CCSD's budget adoption or levy authority, because no town body approves the school budget. The mechanism by which a municipal change would affect CCSD is boundary alteration: if a town or village incorporation, annexation, or deannexation changed which territory lies within CCSD, the district's tax base and enrollment could shift. No such boundary change is pending for CCSD.

Research checked CCSD board and budget pages, NYSED regionalization correspondence including a November 20, 2024 letter from CCSD, Town of New Castle and Town of Greenburgh sites for annexation or incorporation items implicating CCSD, and county and federal sources on the Westchester housing settlement and Chappaqua Crossing listings. No references to boundary changes, mergers, splits, deannexations, or reorganizations affecting CCSD were found as of the research date. The district's official website does not reference any pending structural reorganization.

Real estate and the price of admission

The Chappaqua Central School District spans portions of six ZIP codes in Westchester County: 10504, 10510, 10514, 10546, 10549, and 10570. Zillow's Home Value Index (ZHVI), allocated to the district through the NCES-ZCTA relationship file, produces a typical home value of $1,290,177 as of April 30, 2026, drawing from all six ZIP codes. Zillow's Observed Rent Index (ZORI), allocated the same way from three of those ZIP codes, produces a typical rent of $3,837 as of the same date. Both figures are ZIP-level approximations. ZIP code boundaries do not align with school district boundaries, so these numbers reflect the broader postal areas that overlap the district rather than a precise district-wide measure. A given property within one of these ZIP codes may or may not fall inside the district's enrollment catchment. District enrollment was 3,578 in the 2023-24 school year.

Residential development pipeline

One residential project was under active municipal review during the 2025-2026 period. The proposed 50 North Greeley Avenue development in the Chappaqua hamlet of the Town of New Castle would construct a four-story mixed-use building containing 50 rental units and ground-floor commercial space. The project remained under Town Board special-use and site-plan review as of the cited record, with no approved construction start date. A Town staff memo discusses construction sequencing requirements that must be satisfied prior to site-plan signature.

The Town's revised Full Environmental Assessment Form (FEAF), dated January 31, 2025, applies district-specific public-school-attendee multipliers drawn from the 2021 Chappaqua Central School District Enrollment and Capacity Analysis. The FEAF characterizes the projected enrollment effect of the 50 North Greeley Avenue project as nominal and within district capacity. No project-specific tax-revenue estimate has been published in the reviewed materials.

Zoning changes

The Town of New Castle adopted zoning text to enable a site-specific special permit for the 50 North Greeley Avenue property, designated as the NG Zero special permit framework. This zoning mechanism allows review of the proposed four-story mixed-use project on a parcel-specific basis rather than under the underlying zoning district's general standards. The implementing application for 50 North Greeley Avenue remained under Town Board review through the 2025-2026 period. No other zoning changes affecting district territory were identified in the Town's approved legislation hub or current land use applications page during the review window.

Commercial tax base

The 50 North Greeley Avenue project represents the sole commercial tax base addition identified in the reviewed municipal materials. It would introduce ground-floor commercial space as part of the mixed-use redevelopment. The project had not been approved for construction as of the cited record, and no estimate of its assessed value or projected tax revenue has been published. No other commercial tax base additions, industrial development agency projects, or catalyst-listed economic development projects within the district's boundaries were identified in the reviewed materials, which included Westchester County IDA reports and the Catalyst New Castle program page.

PILOT and abatement review

The reviewed materials included district exemption-impact and budget exhibits covering PILOT (payment in lieu of taxes) lines, district adopted budgets for 2024-25 and 2026-27, and audited financial statements for fiscal years 2023-24 and 2024-25. No PILOT agreement, tax abatement, or similar revenue-diversion mechanism affecting the district's tax base was identified in these sources as of the review date of July 24, 2026. The absence of a PILOT in the reviewed record means that no special tax-payment arrangement was found that would divert property tax revenue from the district's general fund during the periods examined.

Infrastructure and transit access

The Town of New Castle is advancing the ChapLine Multi-Use Pedestrian Trail Way, a 1.7-mile off-road trail that would connect the Chappaqua Metro-North station and Robert E. Bell Middle School with Chappaqua Crossing and Horace Greeley High School. Design and implementation materials are published on the Town's official project page. The trail is described as an active town project. If completed, the trail would provide a continuous pedestrian and bicycle route linking transit infrastructure with two district schools and the Chappaqua Crossing development.

Separately, a Westchester County housing page lists Chappaqua Crossing Apartments in the Town of New Castle, providing program details and application context. The county page does not assert immediate unit availability.

The choice ecosystem

Chappaqua Central School District operates only zoned district schools. It is not a charter school authorizer. In New York, charter authorization occurs at the state level through entities such as the Board of Regents, and the district's own school listings show no charter schools operating within its boundaries. Families residing in the district who wish to pursue a charter school would need to seek placement through the state's charter authorization process, which functions independently of the district.

New York offers charter schools, magnet schools, homeschooling, and interdistrict choice, but it does not offer any education savings account, voucher, or tax-credit scholarship program. No local uptake or fiscal effect for Chappaqua CSD related to such programs is published, because no such program exists in the state to generate uptake or fiscal impact.

The district has no districtwide magnet system. Horace Greeley High School hosts the LIFE School, which operates as a school-within-a-school or lab program rather than a standalone magnet with its own enrollment boundary. Participation is by student application within Horace Greeley High School. Students must already be enrolled at Greeley to apply; the LIFE School is not a separate admissions pathway accessible to students from outside the school or district. The program functions as an internal curricular option rather than a school choice mechanism in the conventional sense.

Several private schools serve families in the broader Westchester region. District transportation may extend to resident students attending these schools if they live not more than 15 miles from the school they attend, consistent with New York State requirements. The Hackley School, a K-12 institution, lists 2026-2027 tuition of $52,880 for Lower School (grades K-4), $58,260 for Middle School (grades 5-8), and $61,895 for Upper School (grades 9-12), with a five-day boarding fee also published. Rye Country Day School, serving Pre-K through Grade 12, lists 2026-27 tuition of $53,210 for Pre-K through Grade 4, $55,540 for Grades 5-8, and $59,070 for Grades 9-12. The Masters School, serving middle and upper school grades, lists 2026-2027 day tuition of $65,800 for both Middle School and Upper School, with five-day boarding at $77,200 and seven-day boarding at $83,350. The Harvey School, serving Grades 6-12, lists 2026-27 tuition amounts by grade span on its tuition page. Rippowam Cisqua School, serving Junior Pre-K through Grade 9, does not have a published tuition figure in the available research.

New York State tracks homeschooling through its home instruction regulations. The district references homeschooling as a recognized option under state law. No specific microschool activity within Chappaqua CSD boundaries is documented in the available research. The state tracks homeschooling but does not separately track microschools as a distinct category, so any microschool activity would not appear in official enrollment data.

Programs, logistics, and special populations

Special education

Chappaqua CSD structures its special education services around what the district describes as a continuum of services in the least restrictive environment. The governing principle is that students participate in general education to the maximum extent appropriate, with special education teacher services layered in where needed. The district lists several specific program types: Consultant Teacher, in which a special education teacher provides support within or alongside the general education classroom; Integrated Co-Teaching, where a general education teacher and a special education teacher share instruction in the same classroom; and Resource Room or Learning Center, which provides targeted small-group instruction outside the general education setting for portions of the day.

At the high school level, the district offers a Transition Support Program for grades 9-12, focused on post-secondary planning and life skills, and Pathways, another high school program whose specific structure is not further detailed in the available sources. When a student's needs cannot be met within any of these in-district programs, the district arranges out-of-district placement, which may involve specialized schools or programs outside Chappaqua CSD.

The district's Individualized Education Program count and rate are not reported in the available federal data for 2023-24. The computed enrollment data reports these figures as missing, so the share of the district's 3,578 students receiving special education services cannot be stated from the available quantitative data.

English learners

The district operates an English as a New Language (ENL) program through its Pupil Personnel Services department. The available research does not describe a dual language or bilingual program within the district; ENL instruction, which focuses on English language development, appears to be the primary model. The computed enrollment data for 2023-24 does not include an English learner count or rate, as these figures are reported as missing. Without a published count, the size of the English learner population and the specific instructional configurations used to serve them cannot be characterized from the available sources.

Pre-kindergarten

The district uses a mixed pre-kindergarten model. The district's pre-K page references local providers including Healthy Kids and Play Care Early Learning Center for Pre-K services. A mixed model typically means that pre-K is delivered through a combination of district-operated classrooms and partnerships with community-based providers, though the specific allocation of seats between district and partner sites is not detailed in the available research. The number of pre-K seats, the number of participating classrooms, and the eligibility criteria, whether universal or targeted by income or developmental need, are not specified in the available sources.

Career and technical education

Chappaqua CSD does not operate its own career and technical education (CTE) center. Students access CTE programs through the Tech Center at Yorktown, affiliated with the regional BOCES. Available programs include Cosmetology, Barbering, Carpentry, Culinary Arts, and Auto Mechanics/Collision Repair. These programs typically operate as half-day placements: students spend part of their day at the Tech Center receiving specialized career instruction and part of their day at Horace Greeley High School completing academic requirements. The BOCES model is a regional shared-services mechanism that allows districts like Chappaqua to offer specialized career pathways without maintaining standalone facilities for each trade. Tuition for BOCES programs is paid by the home district through a regional cost-sharing arrangement rather than by individual families. A BOCES services guide and event calendar are published for families considering these pathways.

Athletics and arts

The district reports that over 500 students participate in athletics each season, filling more than 2,000 team positions annually across three seasons. The athletic program includes offerings less commonly found in public school districts, specifically skiing, bowling, and ice hockey, in addition to more standard sports. An athletics program overview is published for incoming grade 9 students. Theatre and auditorium facilities at Horace Greeley High School and Seven Bridges Middle School are available for community use under the district's facilities use policy. The district also highlights STEAM centers and design-thinking opportunities across grade levels, integrating arts with science, technology, engineering, and mathematics instruction.

Transportation and bell times

Resident students are eligible for district transportation if they live not more than 15 miles from the school they attend. This eligibility extends to both public and private school students, consistent with New York State education law, which requires districts to transport resident students to private schools within certain distance parameters. Bell times for secondary schools are: middle school 7:55 AM to 2:30 PM, and high school 7:45 AM to 2:35 PM. Elementary bell times are not specified in the available research. The secondary start times are earlier than the 8:30 AM threshold recommended by the American Academy of Pediatrics for adolescent students, though the district's specific rationale for these schedules is not documented in the available sources.

Before and after school care

The district references local before and after-school childcare and Pre-K providers on its community page. Chappaqua Children's Workshop (CCW) operates before and after care with hours from 7:30 AM to 6:15 PM, covering the gap between parent work schedules and the school day. CCW's handbook lists an annual membership fee of $100.00 per child as the most recent posted figure. Additional providers referenced by the district include Healthy Kids for Pre-K and Play Care Early Learning Center for Pre-K. The available research does not specify waitlist status, capacity limits, or current tuition rates beyond the CCW membership fee. Families should contact providers directly for current availability and pricing.

Class size

Contracted class size limits in the district's collective bargaining agreement, covering July 1, 2025 through June 30, 2030, include a maximum class size of 28, a kindergarten ratio of 20:1, and a grade 1 ratio of 23:1. Additional guidance and exceptions apply to certain large-group secondary classes. These caps are contractual obligations, enforceable through the grievance and arbitration procedures in the labor agreement, rather than merely aspirational policy targets. The district also maintains a separate class size policy on its board of education policies page.

Calendar

The district maintains academic calendars and bell schedules on its website. The available research confirms that published schedules exist but does not specify the exact dates of the 2025-26 or 2026-27 academic calendars beyond the existence of these posted resources. Families can consult the district's calendar page for first and last days of school, holiday recesses, and professional development days.

Safety, climate, and community

The district reports safety incidents through New York State's School Safety and the Educational Climate (SSEC) system, which covers July 1 through June 30 and counts verified violent or disruptive acts occurring on school property, school buses, or at school functions. The SSEC framework maintains separate counts for incidents, offenders, and targets or victims, meaning a single physical altercation could produce three separate tallies. Certain incident categories within the SSEC require all three of the following criteria before an event is counted: the offender is age 10 or older, the conduct is felony-level after considering developmental capacity, and there is a police referral. This threshold means the SSEC data set captures a narrower subset of incidents than a school's internal discipline records, and raw counts without these definitional parameters can mislead readers who assume the number reflects all behavioral incidents in a given year. The most recent SSEC report on file covers the 2024-25 school year under the "Rest of State" category, which applies to districts outside New York City. The NYSED glossary defines each incident category that districts must verify before submission.

Federal civil rights data from the 2021-22 school year provides a separate view of exclusionary discipline through the US Department of Education's Civil Rights Data Collection. In that year, the district recorded 33 in-school suspensions of students without disabilities. Of those, 22 involved White male students, 6 involved White female students, 2 involved Hispanic female students, and 1 each involved Hispanic male, Asian male, and Hawaiian/Pacific Islander male students. For out-of-school suspensions, 12 students without disabilities received a single suspension during the year: 7 White male students, 2 Hispanic male students, 1 Hispanic female student, 1 Asian male student, and 1 male student of two or more races. Two students without disabilities received multiple out-of-school suspensions: 1 Asian male student and 1 White male student. No students without disabilities in the Black, American Indian, or English-learner categories received in-school or out-of-school suspensions in that year, according to the federal data. These figures cover only students without disabilities; students with disabilities are reported under separate CRDC categories not included in the data on file here.

The district maintains a school resource officer program. According to the district's stated policy, student discipline is governed by the district Code of Conduct and handled by school personnel, while SROs function as safety resources and are not school disciplinarians or investigators. This delineation means that the SRO role, as the district defines it, is separated from the disciplinary process that produces the suspension counts above.

Regarding student cell phone use, District Policy 5031 restricts student use of internet-enabled devices during the school day and applies the Code of Conduct to related infractions, with limited exceptions and enforcement details governed by the policy. New York State requires bell-to-bell smartphone restrictions statewide as of September 2025, and Chappaqua implements this requirement through Policy 5031. The state mandate, announced by Governor Hochul's office, applies to all public school districts.

On school climate measurement, the district administers the Panorama Education Student Sense of Belonging Survey to students in grades 6 through 12. The survey was administered in February 2026 for the 2025-26 school year. No quantitative headline figure from this survey is published on the district's accessible page, which means families cannot independently verify survey results from publicly available district materials at this time.

Two contested matters have surfaced in recent years that bear on district governance. The first involves a student represented by the Foundation for Individual Rights and Expression (FIRE) who challenged district discipline imposed for off-campus expression beginning in April 2024. The student argued the speech was constitutionally protected and nondisruptive, while the district maintained its policy applied after complaints were received. In May 2025, the district adopted Regulation 7025, which addresses speech standards for students, faculty, and staff. FIRE reported on June 25, 2025 that the parties resolved the matter and that FIRE agreed to drop the lawsuit. Because the accessible account of the resolution comes from one litigant rather than a retrieved dismissal order or district statement, the settlement details remain single-source.

The second matter involves the Chappaqua Congress of Teachers and retirees, who contended in an October 2024 filing that district agreements required reimbursement of Medicare Part B income-related surcharges for certain retirees. The district sought dismissal on procedural grounds. On May 14, 2025, the Appellate Division, Second Department, affirmed the dismissal of the Article 78 petition but reinstated the breach-of-contract cause of action for the union and 32 individual plaintiffs. The appellate decision did not resolve the breach-of-contract claim on its merits, leaving the underlying question of whether the district owes these reimbursements unanswered.

Leadership, governance, and labor

Superintendent and cabinet

Christine Ackerman has served as Superintendent of Schools since July 6, 2017. Her current contract runs through June 24, 2028, under a Second Addendum dated June 25, 2024 that extended the term from its prior June 24, 2027 expiration. The base agreement was dated June 25, 2022. Before joining Chappaqua, Ackerman served as superintendent of the Greenwood Lake Union Free School District. The district's leadership page lists her cabinet: Andrew Corsilia as Assistant Superintendent for Human Resources and Leadership Development, Joshua Culwell-Block as Assistant Superintendent for Business, Yasmin Helou-Care as Assistant Superintendent for Pupil Personnel Services, James Block as Director of Athletics, Physical Education and Health, Sara Kenney as Director of Special Education and 504 Services, and Mario Martinez as Director of Facilities, Operations and Maintenance.

Superintendent turnover

Over the past decade, four individuals have served as superintendent, including two interims who served sequentially. Lyn McKay held the position from July 1, 2011 until her resignation, which the Board of Education accepted on November 1, 2016. The Daily Voice reported the resignation as occurring amid fallout from a sex-abuse scandal; the resignation itself is the documented fact, and the surrounding circumstances are reported, not adjudicated. Eric Byrne then served as interim superintendent from November 1 to December 5, 2016, followed by Daniel McCann as interim from December 6, 2016 to June 30, 2017. Ackerman began her tenure the following day. The district thus experienced approximately eight months of interim leadership between McKay's departure and Ackerman's arrival, with a mid-window transition between the two interim appointees.

Board of Education

The Board of Education comprises five members, all of whom have joined since 2023. Alissa Dorfman serves as President, having first been elected in 2023 and re-elected in 2026, with her current term expiring in 2029. Allison Steinbauer serves as Vice President, first elected in 2025 with a term expiring in 2028. The remaining trustees are Matt Auerbach (first elected 2023, re-elected 2026, term expires 2029), Cailee Hwang (first elected 2024, term expires 2027), and Tim McNamara (first elected 2025, term expires 2028). Board officer roles have rotated: a district announcement records that Hwang was previously elected President with Dorfman as Vice President, and a subsequent announcement records the election of officers for the 2026-27 year, at which point Dorfman became President and Steinbauer became Vice President.

Board elections

Board elections have been contested in each of the last five cycles. In May 2026, Dorfman and Auerbach won re-election. In May 2025, four candidates sought two seats, with McNamara and Steinbauer prevailing. In May 2024, three candidates sought a single seat, with Hwang winning 1,586 votes. In May 2023, four candidates sought two seats, with Dorfman and Auerbach elected. In May 2022, six candidates sought three seats comprising two full terms and one unexpired term. Detailed turnout figures beyond the 2024 vote count for Hwang were not identified in the available sources.

Bargaining units and contracts

Four bargaining units represent district employees: the Chappaqua Congress of Teachers (CCT), the Chappaqua Administrators Association (CAA), the Chappaqua Office Staff Association (COSA), and the Civil Service Employees Association (CSEA) Chappaqua Unit. Collective bargaining agreements are posted on the district's contracts page and are in force. The CCT contract covers the period from 2022 through 2025. The COSA contract covers July 1, 2021 through June 30, 2024. A separate CCT agreement covers nurses, occupational therapists, athletic trainers, licensed practical nurses, and physical therapists for the period July 1, 2021 through June 30, 2024. No posted strike or impasse notices appeared on the district site as of July 25, 2026, and no work stoppage history was identified in the available sources.

Board Policy 4000 recognizes the importance of appropriate class sizes, but numeric class-size limits are established in the CCT collective bargaining agreement rather than in statute or board policy. No districtwide class-size compliance report was found in the available sources.

State fiscal monitoring

The district is not under state fiscal monitoring. New York's Fiscal Stress Monitoring System assigned Chappaqua no designation for fiscal stress or environmental stress in either of the two most recent reporting cycles. For the 2024 school-district reporting cycle, the district received a fiscal score of 6.7 and an environmental stress score of 10.0, neither of which triggered a designation. For the fiscal year ending 2025, released in 2026, the fiscal score was 0.0 and the environmental stress score was 3.3, again resulting in no designation. Under the state's methodology, lower scores indicate fewer stress indicators triggered. No state monitor has been appointed for the district.

Pending litigation

Two material litigation matters are pending. The first is Chappaqua Congress of Teachers v. Board of Education of the Chappaqua Central School District, 2025 NY Slip Op 02907, an employment matter concerning retiree Medicare Part B IRMAA reimbursements. A memorandum underlying the dispute was executed on December 14, 2020. The hybrid CPLR Article 78 and breach-of-contract case was commenced on March 31, 2022. The trial court dismissed the action on April 3, 2023. On May 14, 2025, the Appellate Division, Second Department, reinstated the breach-of-contract claim for most plaintiffs while affirming the dismissal of the Article 78 proceeding. The matter is on remand, and the appellate court did not decide the merits of the contract claim. If the union prevails on remand, the district could owe contract remedies related to retiree Medicare Part B IRMAA reimbursements. If the district prevails, no such reimbursement would be due.

The second matter is O.J. v. Chappaqua Central School District et al., S.D.N.Y. No. 7:24-cv-02830, a federal civil rights action filed on April 15, 2024. A motion for preliminary injunction was filed on May 31, 2024. The case remained pending as of mid-2026 according to federal docket entries. The outcome could affect district policies and practices if injunctive or declaratory relief is granted, and damages exposure depends on the merits. The allegations in this case are pending and have not been adjudicated.

Risks and watch items: the forward calendar

Safety plan timeline

The district posted the draft 2026-27 District-Wide School Safety Plan on July 23, 2026. A public hearing is scheduled for August 5, 2026, at which community members can hear and comment on the proposed plan before the Board. The deadline for submitting written feedback on the draft is August 26, 2026. The Board is scheduled to adopt the final plan on September 2, 2026. As posted, the plan remained a draft pending this adoption process, and its contents could change before final adoption. Families seeking to understand the district's emergency-response protocols for the coming school year can track this process through the district's news and announcements page.

Board meetings

The next scheduled public Board of Education meeting after the research cutoff was set for July 30, 2026, at the Education Center. Regular board meetings follow the district's published calendar, and subsequent meeting dates can be confirmed there as they are posted.

Budget and elections

The proposed 2026-27 school-year budget, totaling $150,125,516, went to voters on May 19, 2026, as documented in the district's budget book. A post on the district's official Facebook account indicated that residents voted to pass the school budget and a capital reserve proposition. Certified results and detailed breakdowns were not identified in the sources reviewed. The next annual budget vote and board election cycle would be expected in May 2027, though specific dates had not been posted as of the research cutoff.

Board member terms expire on a staggered schedule that determines when each seat next appears on the ballot. Cailee Hwang's term expires in 2027, requiring an election in May 2027. Allison Steinbauer and Tim McNamara's terms both expire in 2028, requiring an election in May 2028. Alissa Dorfman and Matt Auerbach's terms expire in 2029, requiring an election in May 2029. Historical election results and candidate information are tracked on Ballotpedia.

Contract and term expirations

Superintendent Christine Ackerman's contract runs through June 24, 2028. Whether the district will initiate contract extension discussions before that date has not been publicly scheduled. The CCT collective bargaining agreement covers the period 2022 through 2025, and the COSA agreement covers July 1, 2021 through June 30, 2024. The status of successor agreements for these units was not identified in the available sources. If successor agreements have not yet been reached, negotiations would be a matter to monitor, though no impasse or strike notices were posted as of July 25, 2026. The district's contracts page is where updated agreements would be posted.

Pending litigation dates

Two litigation matters remain pending without specific next court dates identified in the available sources. In Chappaqua Congress of Teachers v. Board of Education, the breach-of-contract claim is on remand following the Appellate Division's May 14, 2025 reinstatement. Proceedings on remand had not been scheduled to a specific date in the sources reviewed. In O.J. v. Chappaqua Central School District, the federal civil rights case filed April 15, 2024 remained pending as of mid-2026. A motion for preliminary injunction filed May 31, 2024 had not been resolved in the sources reviewed. Future court dates in either matter are expected but unscheduled as of the research cutoff.

Other items

The district administered the 2025-26 Student Sense of Belonging Survey in February 2026 for students in grades 6 through 12. The district's accessible page announces results materials but does not publish a single quantitative headline finding. Any subsequent survey administration or expanded results publication has not been scheduled in the available sources. The Board also adopted two policies in mid-2025 that families may see implemented in the coming school year. Regulation 7025, adopted May 21, 2025, addresses student, faculty, and staff freedoms and responsibilities under the First Amendment, articulating protections for expression and standards for when off-campus speech may be disciplined. Policy 5031, adopted June 17, 2025, governs student use of internet-enabled devices during the school day and ties enforcement to the Code of Conduct. How these policies are operationalized in classrooms in 2026-27 will be observable as the school year progresses.

Surprising insights

Several findings in this district's structure and operations may not be apparent even to residents familiar with the schools.

First, a municipal address does not determine school district assignment in parts of this district's catchment area. Chappaqua CSD shares territory with other districts in two municipalities: the Town of New Castle, which is also served by Byram Hills Central School District, and the Town of Mount Pleasant, which is also served by Pleasantville Union Free School District, Ossining Union Free School District, and Pocantico Hills Central School District. Two homes on the same street in either town could be served by different school districts. The district boundary is fixed by state Education Law under Article 37, not by municipal lines, so a municipal map will not answer the question of which district serves a given property.

Second, an elementary school attendance zone does not guarantee a specific middle school assignment. The district's Registrar independently determines both the elementary and the middle school for a given address. No published guarantee tying a particular elementary attendance area to a particular middle school was found in the district's official materials. A family cannot assume that because their address falls within, for example, the Grafflin elementary attendance area, their child will necessarily attend a specific middle school.

Third, the district does not operate a separate, test-in gifted program. Enrichment for advanced learners is provided through the Multi-Tiered System of Supports framework, based on ongoing student data review, rather than through a one-time identification that places students into a fixed cohort. This means that enrichment is not a permanent placement but a flexible determination that can change as student data changes.

Fourth, Algebra is the standard eighth-grade mathematics course for all students, not an accelerated option reserved for a subset. The district's mathematics pathway is described as culminating in Algebra for all students in eighth grade. This is a structural choice that affects how the district sequences mathematics instruction across the middle school grades.

Fifth, Pre-K admission operates through a random drawing rather than neighborhood zoning. For the 2026-27 school year, the district offered 108 Pre-K seats through a lottery, with numbers drawn after the first 108 forming an ordered waitlist. This process is entirely separate from the K-12 neighborhood-zoned assignment model and does not guarantee a subsequent kindergarten seat in a particular elementary attendance zone.

Sixth, a 2021 capacity and enrollment analysis projected that under a higher-growth scenario, Douglas Grafflin Elementary School could exceed capacity in 6 to 9 years and Robert E. Bell Middle School in 12 to 13 years. These projections were made in early 2021 and were based on factors including housing backfill and proposed land-use changes. No active boundary study or redistricting process has been initiated as of the records reviewed through July 24, 2026, but the capacity report's higher-growth scenario remains the most specific sourced signal that pressure could eventually prompt such a discussion.

Best fit: who this district serves well

This section describes the educational and logistical needs the district's documented programs and structures address, and those it does not. It does not describe who families are.

A student ready for advanced mathematics beyond the standard AP sequence has a documented option. The district lists Advanced Topics in College Mathematics as a post-AP offering, meaning that a student who completes AP Calculus BC, for which 100.0% of Grade 11 and Grade 12 test-takers achieved proficiency in 2023-24, has a further course to take without leaving the building. The Science Research Program provides a three-year sequence for students who want to conduct original scientific research, and AP Capstone, consisting of AP Seminar and AP Research, offers a two-year sequence focused on research methods and inquiry.

A student seeking college credit while in high school can access dual-enrollment arrangements through Syracuse University's Project Advance program, the University at Albany (SUNY), Mercy College, and Westchester Community College. Students take courses at Chappaqua that carry concurrent college credit from the partner institution, subject to the partner university's registration requirements and associated fees.

A student interested in International Baccalaureate coursework can pursue the IB Career-related Programme through the LIFE School at Horace Greeley High School. However, this requires application and acceptance into the LIFE program, which is an application-based program operating within the high school rather than a separate school. The district does not offer the IB Diploma Programme, which is a separate, more comprehensive two-year IB qualification. A student specifically seeking the IB Diploma Programme would not find it here.

A family valuing a single K-12 district with no feeder transitions may find the structure relevant. Because Chappaqua CSD is a unified K-12 district, students who begin in the district's elementary schools remain within the same district through graduation, absent relocation or transfer. There is no sending or receiving relationship with another district, and all students converge into a single high school, Horace Greeley, for grades 9 through 12.

A family seeking Pre-K has access to 108 seats through a random drawing for the 2026-27 school year. This is a lottery-based process, not a guaranteed placement, and it is separate from the neighborhood-zoned K-12 assignment model.

A family wanting intra-district school choice does not have a documented option. The district's Policy 5090 on student residence does not provide a mechanism for families to request a different school within the district as a matter of preference. The only transfer-like provision applies after an in-district move, allowing a student to finish the current year at the original school, with the Superintendent's approval and a no-additional-section condition for longer continuity. Transportation is not provided in that situation.

A family needing to verify school assignment for a specific address cannot do so from the district website alone. No parcel-level boundary map is published on the district's retrieved web pages. The Registrar confirms both district eligibility and the specific elementary and middle school assignment, and families must provide an exact street address for this determination.

A family needing extensive special education services, English learner support, or economic disadvantage programs cannot assess the district's offerings from the available public data. Individualized Education Program counts, English learner counts, and free or reduced-price lunch data are all reported as missing in the computed enrollment profile. The CRDC for SY2021-22 recorded 27 students with IEPs and 66 students with Section 504 plans enrolled in AP courses, but these are point-in-time enrollment counts in AP specifically, not a description of the full range of services available. Families with these needs should contact the district's pupil personnel services department directly.

A family needing before- or after-school care or extended-day programs will not find information about these services in the available data. The computed profile and district materials reviewed do not document specific extended-day or childcare arrangements.

Questions parents should ask

1. "Which elementary and middle school does this specific address feed to?" The Registrar determines both assignments independently, and no published parcel-level boundary map exists to verify this independently. Ask the district Registrar.

2. "Is this property in Chappaqua CSD or a neighboring district?" The district shares territory with other districts in the Town of New Castle and the Town of Mount Pleasant, so a municipal address alone does not answer this question. Ask the district Registrar.

3. "What is the current capacity utilization at the school my child would attend?" A 2021 capacity report projected potential over-capacity at Grafflin Elementary in 6 to 9 years and Bell Middle School in 12 to 13 years under a higher-growth scenario, and no subsequent capacity study has been identified. Ask the district's business office or Board of Education.

4. "How does the Pre-K lottery work, and what are the odds of receiving a seat?" Pre-K admission is through a random drawing with 108 seats for 2026-27, and the process is separate from K-12 neighborhood zoning. Ask the district's Pre-K program office.

5. "What is the application process and timeline for the LIFE School?" The IB Career-related Programme is available only through this application-based program at Horace Greeley High School. Ask the Horace Greeley counseling department.

6. "What dual-enrollment courses are available, and what are the associated costs?" The district offers college credit through Syracuse University, the University at Albany, Mercy College, and Westchester Community College, but students must meet partner registration requirements and pay fees. Ask the Horace Greeley counseling department.

7. "How does MTSS-based enrichment work in practice for a student who needs additional challenge?" The district does not operate a separate test-in gifted program; enrichment is determined through ongoing data review within the MTSS framework. Ask the building principal or the pupil personnel services department.

8. "What are the three eighth-grade mathematics options, and how is placement determined?" Algebra is the standard eighth-grade course, with Enriched Algebra listed among three options, and placement is determined through the course-selection process informed by prior performance rather than a single entrance exam. Ask the middle school counseling office.

9. "What transportation is available if we move within the district mid-year?" Policy 5090 allows a student to finish the year at the original school after an in-district move but does not provide district transportation in that situation. Ask the district's transportation office.

10. "What is the district's current fiscal stress designation from the State Comptroller?" The 2024 score was 6.7, resulting in "No Designation" according to the OSC summary report, but this is updated annually and the most recent score should be confirmed. Ask the business office or check the OSC website.

11. "Are there any active boundary studies, redistricting discussions, or capacity reviews underway?" None were identified through July 24, 2026, but the 2021 capacity report flagged potential pressure at specific buildings, and the Board of Education meeting agenda archive is where such items would surface. Ask the Board of Education or monitor the meeting agenda archive.

12. "What special education services are available at the specific school my child would attend?" IEP counts are reported as missing in the computed enrollment data, so the district-level picture is not available from public data sources. Ask the pupil personnel services department.

13. "What is the residency verification process, and what documents are required?" The district requires three proofs of residence, including one primary proof and two recent documents showing the address, and may require proof of residence throughout a student's entire career. Ask the district Registrar.

Scope, method, and sourcing notes

This report covers Chappaqua Central School District (NCES LEA ID 3606990) in Westchester County, New York. It draws on computed data from government sources and acquired research from official district and state publications. The report describes what is documented and does not rate, rank, or recommend.

Enrollment data comes from the NCES Common Core of Data for the 2023-24 school year, reporting 3,578 students across six schools. Race and ethnicity counts and rates are reported for the same year. Free or reduced-price lunch data, Individualized Education Program counts, and English learner counts are reported as missing in the computed enrollment profile and could not be filled from available sources.

Assessment data comes from New York State assessment records via a processed profile corpus. The computed database contains 82 series spanning 2006 to 2025, but the 12 detailed series available for this district each contain a single data point from the 2023-24 school year, all reporting Advanced Placement exam proficiency rates for the "all students" group. No Regents exam data, no subgroup assessment breakdowns, and no multi-year trend data for any single series are available in the computed profile. The database year index lists years from 2006 through 2017, and the interval between 2017 and the 2023-24 data includes the 2019-20 school year, when New York State cancelled standardized assessment administration due to the COVID-19 pandemic.

Graduation data is from the 2019-20 school year, sourced from EDFacts Adjusted Cohort Graduation Rate data via the Urban Institute Education Data API. The cohort size was 299 students. The graduation rate itself is not provided in the computed data. This data is several years old and reflects a cohort whose senior year spring was disrupted by the pandemic. No more recent graduation data is available on file.

Chronic absenteeism data is from the 2022-2023 school year, sourced from EDFacts Data Group 814, reporting a rate of 7.3% for all students in the district.

Civil Rights Data Collection figures are from SY2021-22, covering Algebra I enrollment, suspension data, and AP enrollment across six aggregated school-level records. These are point-in-time counts and do not reflect current-year enrollment or outcomes.

Finance data comes from the US Census Bureau Annual Survey of School System Finances (F-33) for FY2023. The district's adopted budget trajectory is drawn from district budget books for 2023-24 through 2026-27. Fiscal stress monitoring data comes from the New York State Office of the Comptroller's 2024 fiscal stress monitoring system.

No long-run enrollment series was available on file. The most recent sourced directional statements about enrollment and capacity come from a 2021 district-commissioned report. No subsequent capacity study has been identified in records reviewed through July 24, 2026.

No market-level housing or demographic data at the district level was available in the computed profile. No child poverty data was available. No school-by-school assessment breakdowns, per-school enrollment counts, or per-school demographic compositions were available in the computed data.

The district's official website, New York State Education Department publications, Board of Education meeting agendas and minutes, and news coverage from local outlets were reviewed for program information, policy details, governance structure, boundary and capacity questions, and fiscal context. Where the district's own figures are cited, they are labeled as self-reported. Where claims are contested or projected, they are attributed to their source rather than asserted as fact.
