Edgemont Junior-senior High School, Scarsdale NY

Original Research by School Decision on Edgemont Junior-senior High School

Edgemont Junior-Senior High School serves grades seven through twelve in Scarsdale, an affluent residential village in Westchester County anchored by strict zoning, single-family homes, and a controlled commercial center. The school enrolls roughly nine hundred students across six full grades, with a demographic composition that is roughly half white and roughly two-fifths Asian, with smaller shares of Hispanic and multiracial students. Free-and-reduced-price lunch data is not available in the source materials.

The school's academic standing is mixed by grade and subject. In seventh grade, the school shows solid proficiency: roughly four-fifths of students met or exceeded the proficiency threshold in both math and English language arts. Eighth grade reveals a sharper picture. Math proficiency drops to a little above four in ten, with participation in the tested cohort running well below grade enrollment, suggesting that many eighth graders are in an accelerated or alternative pathway not captured in the state assessment data. This pattern aligns with a district curriculum change beginning in 2023-24 that introduced the option for eighth graders to take Algebra, opening faster routes through the high school sequence. English language arts performance in eighth grade stays strong, at roughly four in five. Science proficiency in eighth grade is notably high, at roughly nine in ten.

Across the school's tested grades and subjects, the overall proficiency index places Edgemont above the midpoint among districts in Westchester County. No state testing data is available for high school grades, as New York does not administer standardized state assessments in those grades. Graduation rate data is not provided in the materials, so a family seeking that metric would need to contact the school directly.

The housing market in the Scarsdale zip code reflects the village's character and affluence. Home values are substantial, and rental costs are correspondingly high. New construction in the area centers on single-family teardown-and-rebuild projects. One notable exception is One Dromore Apartments, a newly opened all-electric forty-five-unit affordable housing development in the Edgemont section. The broader market is well-supplied with active listings, and median days on market have shortened, suggesting a moderating pace from earlier peaks in buyer competition.

The district is in the midst of meaningful infrastructure and programming changes. In October 2024, voters approved a capital improvement bond for multi-year facility upgrades across all schools. The bond narrowly passed after a larger proposal was rejected in May, and it carries a lasting tax impact beginning in the 2025-26 school tax year. More immediately, the district launched its first full-day Pre-Kindergarten program with the instructional portion free to families through state subsidy, and is planning expansion through childcare partnerships. The addition of eighth-grade Algebra pathways represents a deliberate curriculum move to increase rigor and align the district with peer schools.

The school's academic design reflects its position in an affluent suburb with a skilled family base. The transition between seventh and eighth grade performance in math suggests intentional differentiation, with advanced students moving into accelerated coursework. For families considering the school, the key items to clarify directly would be the graduation rate, the scope and timing of facilities improvements, and the specific sequencing and capacity of advanced math and science pathways in the high school grades, since state testing does not measure those.

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.
