How this is scored→

What stands out

  • Part of the Ascend Learning charter network, which runs two of the top-scoring schools in District 18
  • 2025 ELA result of 74.7% is the highest in the school's recorded history, after a multi-year dip
  • Grade 7 ELA proficiency at 87.5% is among the strongest single-grade results in the district
  • A single K-8 campus lets siblings stay together through middle school on one site
  • Daily attendance of 96.9% is well above the District 18 average, signaling strong school-day engagement

Things to consider

  • Chronic absenteeism of 93% is unusually high and worth pressing the school on — the pattern of who misses days and why
  • Parent satisfaction at 79% trails the district's 92.8%, and the family survey was essentially silent (4 responses), so talking directly to current families matters
  • Grade-level results vary widely — Grade 5 math at 49.3% is a real concern if your child lands in that cohort
  • As a charter, admission is by lottery, with no guarantee of a seat even for siblings of current students
  • The student body is heavily homogeneous racially, which may matter for families prioritizing day-to-day diversity

Based on 2024-25 data

School SummaryDistrict 18

Academics

Improving

At 74.7% ELA and 69.3% math proficiency in 2025, students here outperform the District 18 average by roughly 16 and 8 percentage points respectively. The school hit an earlier peak around 2018 (70.2% ELA, 73.5% math), softened through the pandemic, and is now posting its highest ELA mark on record. Grade-by-grade results are uneven — Grade 7 hits 87.5% in ELA while Grade 5 math lands at 49.3% — so the experience depends meaningfully on which cohort your child lands in.

Culture

moderate

Daily attendance is strong at 96.9% (well above the district's 90.5%), yet chronic absenteeism sits at 93% — a striking pattern that suggests many students have sporadic rather than fully consistent attendance. Parent satisfaction comes in at 79%, noticeably below the district's 92.8%, and the family survey response rate was effectively zero (4 responses), so there is little direct family voice in this picture. Teacher-rated instruction quality is 82.8% — solid but below the district's 89.8%.

Community

The student body is 91% Black with small shares of Hispanic, Asian, White, multiracial, and Native American students, mirroring Canarsie's longstanding Black majority. About 58.5% of students qualify as economically needy — a moderate level for a Brooklyn charter. The school draws from a community where median household income is roughly $82,000 and over half of residents own their homes, a meaningfully middle-class footprint for the borough.

Neighborhood

Canarsie

Canarsie is a stable, family-oriented Brooklyn neighborhood with a median home value near $688,000 and a roughly 13% poverty rate — solidly middle-class for outer-borough New York. About 28.7% of adults here hold a bachelor's degree, and a homeownership rate of 50% is high for New York City, reflecting long-established residential roots. The L train terminus at Canarsie-Rockaway Pkwy anchors the commute into Manhattan and across Brooklyn.

The school is a quick 5-minute walk from the Canarsie-Rockaway Pkwy L stop, with East 105 St (L) about 10 minutes away on foot.
