At a Glance
A tiny zoned STEM elementary in central Harlem where math scores have tripled since 2016, even as overall proficiency still trails the district.
Best suited for
Zoned families who want a tiny elementary with highly engaged parents and zero suspensions, who value the steadily rising math trajectory, and who can supplement at home to help offset chronic absenteeism patterns and below-average proficiency.
Overall Rating
Rating = average of NY State ELA + math proficiency, grades 3–8
Bands are Motley's thresholds on a 0–100 scale, not New York State performance levels.
How this is scored→What stands out
- Math proficiency has risen from 7.5% in 2016 to roughly 25–30% in each of the past three years — one of the steeper improvement trajectories in the data
- Zero suspensions for three consecutive years, contrasting with a district average suspension rate of about 0.39%
- Parent satisfaction and parent-principal trust scores both exceed district averages despite below-average proficiency
- Very small enrollment (114 students) means teachers can know every family
Things to consider
- ELA and math proficiency are less than half the District 3 averages
- Chronic absenteeism affects 43.7% of students — the single biggest academic risk factor here
- Teacher-reported safety sits 7 percentage points below the district average
- PTA fundraising of $12 per student (vs. $627 district average) means very limited budgets for enrichment, field trips, or classroom extras
- Only 11 teachers completed the climate survey, which limits how much weight to give those numbers
Based on 2024-25 data
School SummaryDistrict 3
District 3 contains some of the city's most competitive options — Special Music School (100/100), The Anderson School (98/100), and three Success Academy charters in the 90s — and the STEM Institute sits well below that tier, with an overall quality score of 1.03 out of 4 compared to a district average of 2.27. P.S. 166 nearby also runs ahead. Families who can choose will find stronger academic options within the district; for zoned families, the school offers a small, parent-engaged environment rather than a top-performing one.
Academics
Both ELA (26.5%) and math (25%) proficiency sit well below the District 3 averages of roughly 59% and 54% respectively, and the overall quality score of 1.03 out of 4 is less than half the district average. The more encouraging story is the trend line: math has risen from a deeply low 7.5% in 2016 to 25–29.6% in each of the last three years — roughly a tripling. ELA has been more volatile, dipping to 10.2% in 2022 before recovering to 26.5% in 2025, its highest mark since 2017. Grade 3 and 4 score breakdowns show math still lagging more than ELA in the tested grades.
Culture
The day-to-day feel here is defined by unusually warm parent-school relationships — parent satisfaction (92%), parent-teacher trust (95%), and parent-principal trust (97%) all run above district averages — paired with some real warning signs. The 85.5% attendance rate trails the district's 90.4%, and 43.7% of students are chronically absent, meaning nearly half are missing enough school to materially affect learning. Teacher-reported safety at 87% sits noticeably below the district's 94%, though it's worth noting that suspensions have been zero for three consecutive years and only 11 teachers responded to the survey, which limits how confidently one can read the climate numbers. PTA fundraising of just $12 per student versus the district's $627 means enrichment budgets are slim.
Community
The student body is roughly half Black and a third Hispanic, with smaller White, Asian, and multiracial shares — a diversity index of 66%. The economic need index of 83.9% indicates a population with significant economic disadvantage, and 29% of students have IEPs. Interestingly, the surrounding neighborhood skews more college-educated (51.7% BA+) and has a lower poverty rate (20.3%) than the school population itself, which suggests the zoned enrollment pulls from a more economically mixed swath than the immediate census area.
Neighborhood
South Harlem is a neighborhood where about half of adults hold a bachelor's degree and median household income sits around $68,758, though 20.3% of residents live below the poverty line and only 12.4% of households have children under 18 — a relatively low share that reflects the area's mix of long-time residents and adult households without kids. Homeownership is low (18.2%) and median home values reflect Manhattan's scale.
Three subway options within a roughly six-minute walk: the Cathedral Pkwy (110 St) station on the C and B lines (about 4 minutes), 116 St on the C and B (about 5 minutes), and 110 St–Malcolm X Plaza on the 2 and 3 (about 6 minutes).
