Test scores have risen substantially over the past decade — ELA proficiency climbed from 47.7% in 2016 to 68.3% in 2025, and math from 47% to 70.8% — both now meaningfully above the District 21 averages of 60% and 63.2%. The school earned an overall score of 2.78 out of 4, ahead of the district's 2.46. Grade 3 students post particularly strong results (87% ELA, 82.6% math), though scores dip in middle school — 7th-grade ELA sits at 57.5% and math at 52.6% — before rebounding in 8th-grade math (81.6%). 2025 marks the school's best ELA and math results on record, and the trajectory is clearly improving.

The numbers tell a story of a school where families and teachers feel genuinely connected: parent-teacher trust sits at 98%, teacher instruction quality at 100%, parent satisfaction at 94%, and teacher-reported safety at 98% — all at or above district averages. The 95% family survey response rate and 44 teacher responses suggest an engaged community that feels heard, and discipline is essentially a non-issue, with zero suspensions over the past three years. The one notable flag is chronic absenteeism at 71.5%, meaning roughly three-quarters of students miss 10% or more of school days — even as overall attendance (92.2%) runs modestly above the district average, suggesting the absences cluster around specific students and families rather than reflecting daily culture.

The student body is a genuine mix: 40% Hispanic, 34% White, 17% Asian, and 7% Black, with a diversity index of 73%. About 27% of students have IEPs and 75.8% have economic need — both reflecting the broad range of families the unscreened school serves. The surrounding Mapleton-Midwood neighborhood has a median household income around $71,000, an 18.3% poverty rate, and 41.6% homeownership, with a third of adults holding a bachelor's degree or higher — solidly middle-class Brooklyn that spans longtime homeowners and more recent arrivals alike.

Mapleton-Midwood (West) is a family-heavy stretch of southern Brooklyn — about a third of households here include children, and with a median home value over $1 million and 41.6% of homes owner-occupied, it's a neighborhood with real roots. Median income sits around $71,000, and roughly 36% of adults have a bachelor's degree or higher. The F train runs right through, making it reasonably connected for families coming from elsewhere in southern Brooklyn.

Three F-train stops serve the school: Avenue I and Bay Parkway are each about a 5-minute walk away, and 18 Avenue is roughly 10 minutes on foot.
