Siwanoy School, Pelham NY - Test Scores & Data

Original Research by School Decision on Siwanoy School

Siwanoy School is a small public elementary school serving kindergarten through fifth grade in Pelham, a walkable, affluent residential suburb in southern Westchester County. The school enrolls about average size for its grade band, with roughly equal distribution across its six grades. The student body is predominantly white, with smaller shares of multiracial, Hispanic, Asian, and Black students.

The school's most recent state test results show strong across-the-board performance in math, English language arts, and science. In math, proficiency rates across grades three through five cluster in the low-to-mid range, with third grade performing highest. In ELA, results similarly hold steady in the low-to-mid range across tested grades. In fifth-grade science, proficiency is somewhat lower, at a level that still reflects solid performance but represents a softer spot relative to the other subjects tested. A parent may want to ask the school directly about science instruction and how it supports students working to reach proficiency. When positioned against other districts in Westchester County, Siwanoy's overall proficiency index places it in the top quartile among the county's schools, an indication of strong performance relative to peers.

Free-or-reduced-price-lunch data and special-education enrollment are not available in the reported data; these details might be obtainable directly from the school or the Pelham Union Free School District. The school does not serve high school grades, so no graduation rate applies.

The community context shapes what families find here. Pelham is a built-out, high-demand housing market with median home values in the high range and rents also elevated. The town is defined by single-family, tree-lined neighborhoods within walking distance of a compact downtown with shops, restaurants, cafes, and the Metro-North station, which connects residents to Manhattan in roughly half an hour. This walkable, transit-embedded layout means school life sits within neighborhood fabric rather than on isolated campuses. The town has no single large employer and functions as a bedroom community; residents commute elsewhere for work.

Recent changes at the district level will affect the school's immediate future. In May 2025 voters approved a capital bond that includes an expansion of Siwanoy, paired with ADA upgrades and air conditioning. That bond was approved by a narrow margin and will trigger construction at the school over the coming years. The district has also shifted its science teaching approach toward inquiry-based, project-based methods at the high school level, which may eventually influence elementary science as well. The bond was structured so that existing debt-service budgets will cover the new borrowings without raising property taxes immediately, a detail that shapes the long-term tax picture for families considering the area.

Siwanoy serves families seeking a small, neighborhood-oriented elementary school in an affluent, walkable suburban setting with solid academic fundamentals and proximity to commuter rail. The school's strong proficiency results and compact community context make it a fit for families valuing academic grounding within a residential, transit-accessible town, though families should be aware that the approved capital work will bring construction activity to the school building over the next several years.

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.
