At a Glance
A high-performing charter school with near-universal math proficiency, operating in one of Brooklyn's most education-focused neighborhoods
Families who prioritize academic performance above all else and are comfortable with charter school lottery admissions. The school appears to work well for families who secure spots, but the high chronic absenteeism rate suggests some families may be opting out or struggling with fit. Best for parents who want a high-structure academic environment and can navigate the charter application process.
- Exceptional math proficiency (97.6%) exceeding district average by 34 percentage points
- Near-complete recovery to pre-pandemic performance levels after 2022-2023 dip
- Highly diverse student body (86% diversity index) with balanced racial representation
- Charter model with lottery admissions offering an alternative to zoned schools
- Strong value-added: Grade 4 outperforms Grade 3 significantly in both subjects
- 74% chronic absenteeism rate is extremely high and unexplained — families should investigate why
- Charter school model means no zoned enrollment and lottery-only admissions
- Family survey participation is critically low (1%), limiting transparency into parent experience
- Slightly below-average overall attendance (92.3% vs 93.5% district)
- 15% IEP population suggests some special education services, but charter networks often have limited inclusive programming compared to district schools

School SummaryDistrict 15
Among District 15 peers including P.S. 172 (95/100), P.S. 039 (93/100), and P.S. 321 (90/100), Success Academy Cobble Hill's test scores rank at or near the top — though as a charter, it operates independently from the district's zoned feeder system. The school outperforms every traditional district school in academic metrics, but the chronic absenteeism and lack of survey transparency create a more nuanced picture than raw proficiency numbers suggest.
Test scores here are in a league of their own: 91.9% ELA proficiency and 97.6% math proficiency dwarf District 15 averages of 65% and 63% respectively. Looking at the longer trend, the school peaked in 2019 with near-perfect scores (98.5% ELA, 100% math), dipped during 2022-2023 (dropping to 80% ELA), and has rebounded strongly in the past two years. Grade 4 outperformed Grade 3 in both subjects, suggesting strong value-added as students move up. The 3.79/4 overall score places this among the highest-performing schools in the district.
The data here tells a complicated story. Attendance (92.3%) runs slightly below the district average (93.5%), but the chronic absenteeism figure of 74% is striking — nearly three-quarters of students missed enough school to be considered chronically absent, which is far above typical district rates. The family survey data is essentially unusable (only 2 responses, 1% rate), so we can't draw meaningful conclusions about parent satisfaction or trust. Teacher instruction quality ratings are strong at 89%, and teachers report high safety (97%), but without broader survey participation, the day-to-day climate remains somewhat opaque.
The student body is notably diverse (86% diversity index) with roughly equal representation across Black (26%), Hispanic (28%), and White (26%) students, plus 14% Asian and 6% multi-racial. This differs from the neighborhood's demographics (67% BA+ education rate, median income $140K), suggesting the school draws from a broader cross-section than the immediately affluent surrounding area. At 52% economic need index and 15% IEP students, there's meaningful socioeconomic diversity within the charter model.
This is a family-forward neighborhood with a 67.6% college-educated population and high education orientation (87th percentile), though the 20.8% households-with-children rate is relatively modest. Safety scores are middle-of-the-road (50.57), transit access is moderate (41.76), and the area offers typical Brooklyn urban amenities — brownstones, local parks, and strong community institutions. The median home value of $1.7 million reflects the area's desirability for families who can afford it.
The Cobble Hill location is generally walkable from surrounding blocks, with good access to local streets. Families from further afield typically rely on cars or public transit, as transit scores indicate moderate subway accessibility compared to more transit-dense Manhattan or parts of North Brooklyn.
