How this is scored→

What stands out

  • Math proficiency of 76% far exceeds the district average of 57%
  • K-8 pathway means students don't have to transition schools for middle school
  • Small enrollment of 164 students allows for a tight, known community
  • Fourth-grade proficiency is exceptional at 89% ELA and 93% math
  • Parent satisfaction (92%) edges above the district average

Things to consider

  • Chronic absenteeism is very high at 88.3% — most students miss significant school, which can erode even strong instructional quality
  • Suspension rate of 3% runs roughly five times the district average and has been steady for three years
  • Survey data is extremely thin — only 12 family and 2 teacher responses — so satisfaction numbers carry less weight than they appear to
  • Admissions are by charter lottery, so neighborhood families have no guaranteed seat
  • Student demographics are not very diverse (88% Black), which may or may not matter to your family
  • As a small school, elective offerings and social circles are narrower than at larger campuses

Based on 2025 data

School SummaryDistrict 17

District 17 is home to some of Brooklyn's highest-performing charters, including several Success Academy campuses scoring in the high 90s. Flatbush Ascend lands solidly in the middle of the pack — clearly above average on academics and satisfaction, but well below the top charter options in the area, and ahead of most neighborhood zoned schools.

Academics

Improving

Both ELA (68.3%) and math (76%) proficiency sit comfortably above District 17 averages of roughly 61% and 57% respectively, and the school's overall quality score of 2.89/4 beats the district's 2.36. The most striking story is the 2025 jump: math climbed from 50% in 2024 to 76%, and ELA from 50% to 68% — a dramatic one-year leap that reflects either a real turnaround or a shift in who's testing, and is worth asking about. By grade, fourth-graders are the standout (89% ELA, 93% math), third-graders are strong (67% ELA, 83% math), and fifth-graders trail (60% ELA, 60% math) — suggesting that scores are concentrated in the younger grades.

Culture

strong

On paper, families are happy here: 92% satisfaction (above the 91% district average), 89% parent-teacher trust, and 88% parent-principal trust. But those numbers come from just 12 family and 2 teacher responses — an extremely thin sample, so take the percentages with a grain of salt. Discipline is the more concrete story: a 3% suspension rate runs roughly five times the district average of 0.55%, and total suspensions have held steady in the low-to-mid 20s over the past three years — not a crisis, but a steady pattern. The daily attendance rate of 95.4% is solid, yet 88.3% of students are flagged as chronically absent, meaning most kids miss enough school days to qualify.

Community

The student body is 88% Black, with small shares of Hispanic (6%), multiracial (2%), Asian (1%), White (1%), and Native American (2%) students, giving the school a diversity index of 30% — fairly homogeneous but reflective of the surrounding East Flatbush-Erasmus neighborhood, which is a long-established Caribbean and African American community. About 67% of students qualify for economic need and 15% have IEPs, both meaningful shares. With only 164 students total, families will likely know most other families in the building — a tight-knit feel rather than an anonymous one.

Neighborhood

East Flatbush-Erasmus

East Flatbush-Erasmus is a predominantly renter neighborhood in central Brooklyn, with just 17% homeownership and a median home value around $710,000. Median household income sits at roughly $72,000 — solid working- and middle-class — and about a third of adults hold a bachelor's degree or higher. Around 13% of households include children, and the poverty rate runs about 16%. The neighborhood has a strong Caribbean cultural presence, including along the commercial stretches near the subway stops, and feels residential and family-oriented rather than touristy or transient.

The 2 and 5 trains at Church Avenue are about a 6-minute walk away, the 2/5 at Winthrop Street about 7 minutes, and the Q at Parkside Avenue about 9 minutes — three solid subway options within an easy stroll.
