Mamaroneck Avenue School, Mamaroneck NY

Original Research by School Decision on Mamaroneck Avenue School

Mamaroneck Avenue School is a kindergarten through fifth-grade elementary school in the village of Mamaroneck, a walkable waterfront community in Westchester County with dense residential neighborhoods mixed with active commercial corridors. The school sits on the Mamaroneck Union Free School District's suburban campus, west of downtown Mamaroneck Avenue, serving a community of roughly half the village's population.

The school's enrollment is small to mid-sized for its grade band, with roughly balanced grades across the span. About half the student body qualifies for free or reduced-price lunch, indicating a community with mixed economic circumstance. The student population is predominantly Hispanic, with substantial populations of white and multiracial students, and a smaller number of Asian and Black students. The district's Dos Caminos dual-language Spanish-English immersion program is available at this school, starting in kindergarten and continuing upward as an established district pathway.

State testing data from 2024-25 shows academic performance at or below the midpoint among Westchester County districts. In mathematics, proficiency rates range from just above half in third grade and fifth grade to just under two-thirds in fourth grade. English language arts proficiency is lower, with third grade notably weak, fourth grade near half, and fifth grade above half. Fifth-grade science proficiency sits at about midpoint. Test participation rates are solid across subjects and grades, ranging from three-quarters to near full participation. A parent may want to look into the school's current instructional strategies and support systems with administrators, given that these proficiency levels suggest room for growth.

The district approved a major capital bond in May 2024 that included Phase 1 improvements at this school: pool and locker-room renovations, roofing and HVAC upgrades, masonry restoration, and accessibility enhancements. Additional bond-funded phases are scheduled through 2026 and beyond, so the learning environment is in active modernization.

Mamaroneck itself is a compact, high-density community with strong walkability, particularly in downtown, and a genuine sense of street life centered on Mamaroneck Avenue with shops, restaurants, and gathering spots. Harbor Island Park, a 44-acre waterfront asset with beaches, playgrounds, courts, and recreation, anchors daily family life. The village has good transit access via Metro-North rail to New York City and Connecticut. The community is undergoing downtown revitalization efforts, including zoning explorations for mixed-use development near the station and pursuit of state funding for streetscape improvements and housing that includes affordable units.

Housing values in the zip code are substantial, and rents are correspondingly high. Property taxes are a recurring consideration; the district kept its most recent tax-levy increase under the state cap. The local employment base centers on education, finance/insurance, and health care.

For families, Mamaroneck Avenue School offers a small-school setting within a district that has made infrastructure investment and is building an explicit bilingual pathway. The academic results suggest a school that serves its community but whose students are performing below the typical benchmark for the county, so fit depends on whether a family is drawn to the size, the dual-language option, the waterfront community character, and the school's trajectory as building improvements complete. Prospective families would benefit from visiting the school and understanding its current academic support structures in detail.

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.
