Original Research by School Decision on Stewart Manor School

Stewart Manor School is a small elementary school serving prekindergarten through sixth grade in a densely populated residential village on western Nassau County's Long Island. The school enrolls a mix of students across a range of family backgrounds: roughly a quarter qualify for free or reduced-price lunch, and the student body reflects strong diversity, with Asian, Hispanic, and white students each representing meaningful shares of enrollment, along with students from Black and multiracial families. The school is housed in the Elmont Union Free School District, which spans the neighboring village of Elmont and shares Stewart Manor's position as a built-out, established suburban area.

Stewart Manor School's recent state test results show proficiency rates that vary notably by grade and subject. In math, fourth graders performed strongest, with most students reaching proficiency, while fifth-grade math performance was substantially lower. Sixth-grade math rebounded to strong performance. English language arts shows a similar pattern: third grade sits below the midpoint while fourth through sixth grades reach or exceed it. Fifth-grade science proficiency fell notably below the midpoint, suggesting that subject area may benefit from closer attention at that grade level. Across all tested subjects and grades, the school's overall proficiency index places it above the midpoint when compared to other schools in Nassau County, though the floor on third-grade math and science suggests room for growth in upper elementary.

The broader context matters here. The Elmont district has recently adopted a structured-literacy phonics program, Wilson Fundations, in the earliest grades to build reading foundations more systematically. The district also expanded to full-day prekindergarten in all its schools starting in 2022-23, replacing part-day programs, which affects how families with younger children experience early learning. A substantial capital bond approved by voters is funding air-conditioning and modernized HVAC, secured entrances, and asbestos remediation across all district buildings, a multi-year investment that will touch classroom conditions as it rolls out.

Stewart Manor village itself is compact and walkable, tree-lined, and predominantly owner-occupied single-family homes in classic Long Island styles. The housing market is affluent; median home values are well above national benchmarks and have appreciated steadily. The LIRR Stewart Manor station provides a direct commuter link to Manhattan, anchoring the local economy alongside nearby Northwell Health facilities. This is an established, built-out community with limited new construction, where families tend to settle for stability rather than growth.

The school serves families who have chosen or stayed in a small, tight-knit suburban village with strong owner-occupied housing and easy rail access to the city. A parent considering Stewart Manor should weigh the above-median proficiency standing against the variability within grades, and may want to inquire with the district about how the new phonics approach is being implemented at this school and whether the science curriculum is receiving the support it may need at the fifth-grade level.

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.
