Original Research by School Decision on Ps 310 Marble Hill
PS 310 Marble Hill is a small elementary school in the Kingsbridge neighborhood of the Bronx, serving pre-kindergarten through fifth grade. The school enrolls a small student population with an enrollment concentrated in the lower grades. About all of the school's students qualify for free or reduced-price lunch, reflecting the economic circumstances of the neighborhood. The student body is predominantly Hispanic, with smaller populations of Black, Asian, and multiracial students.
The school's recent state test results show proficiency rates in the low-to-mid range across subjects and grades. In mathematics, proficiency runs between roughly a third and just under a half of students across third, fourth, and fifth grades, with fourth graders performing slightly higher than the others. English language arts results are comparable, with fifth grade showing relatively stronger performance than earlier grades. In science, tested only in fifth grade, proficiency is just under a half. The school participates fully in state testing with participation rates near or at full levels, suggesting consistent assessment engagement across the school's grade span.
Relative to the other districts in Bronx County, PS 310's overall proficiency rate sits in the top quartile, positioning it above the median of its comparison peers. This matters as a context: the school is performing better than most other schools serving similar grade bands in the county, though proficiency rates across tested grades and subjects remain below a majority of students in most cases.
The school operates within New York City Geographic District 10, which covers parts of the northern Bronx including Kingsbridge, Marble Hill, and surrounding neighborhoods. Like the rest of the city's elementary schools, PS 310 was required in the 2024-25 school year to adopt one of the Department of Education's three approved, phonics-based reading curricula, ending the prior flexibility that allowed individual schools to select their own literacy programs. This is a lasting shift in how reading instruction is structured.
The Kingsbridge neighborhood where the school sits is part of a physically varied Bronx landscape. The area has a walkable character with hillside step streets creating a village-like feel, and it is served by subway access and local bus routes. The neighborhood is part of a borough experiencing substantial growth in affordable housing and development, with major projects like Fordham Landing South and renewed investment in transit infrastructure, including planned new Metro-North stations. Housing values in the area are below the state benchmark, and rental costs have risen in recent years. The Bronx as a whole is anchored by health care employment, parkland including Van Cortlandt and Bronx Parks, and a dense public transit system.
State assessment data for earlier grade levels served by the school was not available; the school tests only third through fifth grades under New York's testing regimen. A parent evaluating this school may want to ask the school directly about approaches in the pre-K and kindergarten years, as well as about how the transition to the mandated reading curriculum has been implemented and how literacy instruction unfolds day to day. The school's above-county-median proficiency position is worth context-setting: it reflects strong performance relative to other elementary schools in the county, though absolute proficiency rates suggest a need for instructional attention in both math and ELA.
