At a Glance
A high-performing screened middle school where nearly every family rates trust in leadership at 99% — and math scores routinely top 90%
Families seeking a high-performing screened middle school with a collaborative, low-stress culture — particularly those who value math rigor (all students take Algebra Regents), strong parent-leadership relationships, and a smaller school community. This school appeals to parents who want academic excellence without the hyper-competitive atmosphere of some Manhattan screened schools, and who are comfortable with a more homogeneous demographic profile.
- Math proficiency consistently above 90% — a rare achievement in NYC middle schools
- 99% parent-principal trust rating, suggesting exceptional leadership communication
- Zero suspensions for three of the past four years — an unusually positive disciplinary environment
- 100% program richness score with offerings from fencing to forensics to an Algebra Regents class for all 8th graders
- Every student takes Algebra Regents — a rigorous math pathway that most NYC middle schools don't offer
- Small enrollment (340 students) creates an intimate community feel across grades 6-8
- Dedicated after-school program run by Manhattan Youth included for all students
- The screened admissions process means this isn't a zoned neighborhood school — families must apply and students are selected
- 8th grade ELA (80.6%) lags behind 7th grade (91.4%), which may indicate a curriculum or transition challenge at the upper grade level
- Demographics skew white (49%) and affluent (21% economic need) — this may or may not match a family's priorities for diversity
- Lower PTA fundraising per student ($362) than district average ($517) — though total dollars raised are still healthy
- Only 24 teacher survey responses — while trust scores are high, the sample is small
- The chronic absenteeism data appears anomalous and warrants direct inquiry to the school
Based on 2024-2025 data
School SummaryDistrict 2
Salk sits among District 2's strongest performers — while peer schools like P.S. 77 Lower Lab School (99/100) and Success Academy charters (95-96/100) edge ahead on some metrics, Salk's 3.54 overall rating and 87-90% proficiency rates place it firmly in the top tier. The key differentiator is the culture: unlike many high-performing screened schools that can feel competitive or transactional, Salk's near-unanimous trust scores and zero-discipline record suggest a community that works for families as much as for academics.
Salk's academics are exceptional by any measure — 87% ELA proficiency and 90% math proficiency compared to district averages of 73% and 73% respectively, placing this school firmly among Manhattan's top performers. The historical trend shows remarkable consistency, with math particularly strong (92.9% in 2024-25) and ELA hovering in the high 80s. There's a notable dip in 8th grade ELA (80.6%) compared to 7th grade (91.4%), suggesting the upper-grade transition or Regents prep might warrant attention, though the school's overall 3.54 out of 4 rating significantly outpaces the district average of 2.91.
The climate data reads like a blueprint for what parents hope for: 94% parent satisfaction, 96% parent-teacher trust, 99% parent-principal trust, and teachers rating instruction quality at 99%. Attendance sits at 95.2%, outpacing the district average of 92%. Discipline is essentially a non-issue — zero suspensions for the past two years and only one the year before. The school runs an advisory system and offers an extensive after-school program through Manhattan Youth, which likely contributes to the strong sense of community. With a 59% family survey response rate and 24 teacher responses, there's solid participation in gauging the school's environment.
This is a notably homogeneous student body in a neighborhood that's also affluent and highly educated: 49% white students, 30% Asian, with only 12% Hispanic and 2% Black enrollment. The diversity index of 71% reflects a mix of backgrounds, though the school's demographics skew whiter than Manhattan overall. Economic need sits low at 21.2%, and 20% of students have IEPs — a fairly standard proportion. The PTA raised $123,194 last year (about $362 per student), which is lower than the district average of $517 per student but still substantial, likely reflecting the community's capacity to give time rather than money. The school's small size (340 students across three grades) means class sizes average 25.8 — nearly identical to the district average.
Gramercy is one of Manhattan's most family-friendly neighborhoods — the data shows a 95.02 family density score and 96.93 education orientation score, meaning families with children are common and academic expectations run high. Median household income of $153,847 and homeownership at nearly 40% create a stable, prosperous community. Transit access is exceptional (97.7 score), making the school reachable from across the borough. The trade-off is a neighborhood with relatively high crime density and collision rates, though it's considered safe enough for families — the safety score of 17.24 reflects this as a quieter, more residential pocket amid Manhattan's density. Nearby parks and the overall tree-lined character give kids space to breathe.
Very walkable — Gramercy's compact layout and strong transit scores mean most families walk or take short subway rides. The school is accessible without a car for virtually all residents of this neighborhood and surrounding areas.
