How this is scored→

What stands out

  • Math proficiency of 91.7% — nearly 35 percentage points above the district average
  • Strong post-pandemic academic recovery, with both ELA and math trending up significantly since 2022
  • Part of the Success Academy network, known for a rigorous, college-preparatory approach starting in kindergarten
  • Lottery admissions create a need-blind entry point — no academic screening required to enroll

Things to consider

  • Chronic absenteeism is high at 67.7% — a meaningful share of students miss extended periods of school
  • Parent survey data is thin (only 6 responses, 1% rate), so satisfaction and trust figures should be read with caution
  • Success Academy charters run longer school days and have a structured, high-expectations culture that isn't a fit for every child
  • Admission is by lottery — there is no guarantee of a spot, and families should plan a backup option
  • Class sizes around 22 are average for the district, not notably small

Based on 2025 data

School SummaryDistrict 17

Among District 17 schools, Success Academy Flatbush ranks in the top tier, sitting just behind fellow Success Academy campuses in Prospect Heights and Crown Heights and well ahead of the district average of 2.36 out of 4.

Academics

Improving

Test scores here run well above district averages: 82.5% ELA proficiency compared to roughly 60% across District 17, and a striking 91.7% in math against a district average near 57%. The school dipped after the pandemic (ELA fell to 59.7% in 2022) but has climbed steadily since, suggesting the academic program recovered and then some. Both grade 3 and grade 4 scores are strong, with math leading at every grade level — grade 3 hits 94.6% math proficiency. The overall score of 3.48 out of 4 puts the school solidly in the top tier of the district.

Culture

strong

Day-to-day culture is shaped by the Success Academy model — structured, rigorous, and academically focused — but the survey signals are mixed. Parent satisfaction sits at 56%, well below the district average of 91%, while parent-teacher and parent-principal trust hover in the low- to mid-60s. That said, only six families completed the survey (a 1% response rate), so these readings are more of a thin signal than a definitive verdict. Daily attendance is roughly on par with the district at 91.2%, but a chronic absenteeism rate of 67.7% means a significant share of students are missing extended stretches of school — worth asking the school directly how they handle that.

Community

The student body is 85% Black, with smaller shares of Hispanic (8%), White (3%), and multiracial students — a profile that closely mirrors the surrounding East Flatbush-Erasmus neighborhood. With an economic need index of 75.1, three-quarters of students come from lower-income households, and 13% have IEPs. Total enrollment of 573 students keeps the school at a moderate size — large enough to feel like a real school community, small enough that teachers may get to know students well.

Neighborhood

East Flatbush-Erasmus
