Ps 24, Brooklyn NY - Test Scores & Data

Original Research by School Decision on Ps 24

PS 24 is a small elementary school in Brooklyn serving prekindergarten through fifth grade. The school sits in a neighborhood with high housing costs and steep economic need; the overwhelming majority of students qualify for free or reduced-price lunch, and the student body is predominantly Hispanic with smaller populations of Asian, white, and Black students. The school's enrollment is stable across its grade bands, with roughly similar-sized cohorts in each year.

In academic performance, PS 24 shows uneven results that suggest students are building skills gradually through the grades. Third graders are struggling with both math and English language arts, with proficiency rates in the low range. Fourth grade marks a meaningful shift upward, particularly in ELA where proficiency reaches the midpoint. Fifth graders maintain similar gains in ELA and hold steady in math, though both subjects sit below the midpoint. In science, fifth graders show lower proficiency. The school's overall proficiency index places it in the bottom quartile among elementary schools in Kings County, a significant gap from the county median. Across all grades, participation rates in testing are solid, suggesting the school is successfully assessing its students. A parent may want to look into whether the school has targeted interventions in place for early grade literacy and math, and what supports are in place as students transition to middle school.

Brooklyn itself is dense, highly walkable, and in the midst of substantial residential growth, particularly in neighborhoods like Downtown Brooklyn and Williamsburg. The neighborhood texture varies sharply by block; PS 24's area is part of the city's complex urban fabric with mixed commercial and residential corridors. The housing market is expensive and climbing; rental costs and home values are well above state and national medians, reflecting Brooklyn's position as a major residential draw.

District 15, which serves PS 24, has made several recent policy shifts aimed at integration and access. Most significantly, the district eliminated academic screens for middle school admissions in 2019-20, moving instead to a lottery system with reserved seats for low-income students, English learners, and those in temporary housing. This means families cannot rely on test-based advancement to specific middle schools; instead admissions are by preference lottery. The district also rezoned seven elementary schools starting in 2022-23, redrawing attendance boundaries and setting aside seats for historically marginalized students. As of 2025 the district is revisiting elementary admissions again, with proposals ranging from tightening zone boundaries around crowded schools to scrapping zones entirely in favor of a districtwide lottery. For a family considering PS 24, this ongoing policy flux means school access and assignment could shift; prospective movers should track these discussions closely, as they could affect which schools an address qualifies for.

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.
