Ardsley High School, Ardsley NY - Test Scores & Data

Original Research by School Decision on Ardsley High School

Ardsley High School serves a small, affluent residential community in southern Westchester County, drawing students from the Ardsley Union Free School District, which extends into parts of Dobbs Ferry and unincorporated Greenburgh. The high school enrolls roughly eight hundred students in grades nine through twelve, with enrollment spread fairly evenly across the grade bands. The student body is predominantly white, with a meaningful presence of Asian and Hispanic students; data on free-or-reduced-price lunch eligibility and special populations was not available.

The school sits on a campus cluster on Farm Road on Washington Hill, separated from Ardsley's compact downtown and civic anchors. The village itself is a tree-lined, residential community of single-family homes and gated townhome developments, with a small mixed-use center that the village's own downtown revitalization plan identified as lacking in walkability, streetscape quality, and gathering spaces. Civic and school functions are deliberately split; the Ardsley Public Library and historic downtown sit near American Legion Drive, while the schools occupy the hilltop campus. Residents rely on nearby Metro-North stations in Dobbs Ferry, Hartsdale, or Scarsdale, along with the Bee-Line bus system. The South County Trailway, a paved bicycle and pedestrian path on a former rail corridor, runs through town and connects to a fifty-plus-mile regional network.

The housing market reflects the community's affluence and stability. Home values are substantial, well above state benchmarks. The Westchester County real estate market shows steady listing activity, with supply moderately elevated and demand at mid-range levels; homes sell within a compact timeframe. The median listing price sits well above what a typical household income can support using conventional lending, typical of high-income Westchester suburbs where many residents have owned homes for years and turnover is gradual.

The district is in the midst of a major capital investment. In May 2024, voters approved a significant bond measure to modernize all three schools across multiple years, with construction beginning in May 2025. Work includes a resurfaced athletic field, track, and stands at the high school, new security vestibules, and renovated classroom and wellness spaces. This investment will be repaid through property taxes over roughly two decades. Additionally, a 2022 capital reserve allocation funded a district-wide upgrade of HVAC systems to improve classroom air quality, a tangible change to the daily learning environment.

The district has also adopted a Multi-Tiered System of Supports framework alongside an equity initiative and a three-year technology plan, shifting instructional practice toward standards-based, responsive instruction informed by data. This direction signals a district-level focus on inclusive classrooms and tailored student supports.

State assessment data, graduation rates, proficiency benchmarks, and detailed course and program offerings for the high school were not available in the data provided, so a reader looking for those metrics will need to check the school's website or contact the district directly. Similarly, information on staffing, attendance, discipline, and program access at the school level was not included. The school's positioning relative to other high schools in Westchester County could not be determined from the available comparison metrics.

Ardsley High School appears to serve a stable, long-established residential community with substantial resources and an active commitment to facility upgrades and instructional infrastructure. A parent or family considering the school would benefit from seeking out recent state test scores, graduation data, course catalogs, and any available information on academic supports and extracurricular offerings directly from the school or district.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
