Achievement First Endeavor Charter School

Proficiency rates run roughly 4 points above district averages in ELA (57% vs 53%) and a full 12 points above in math (57.7% vs 46%) — a meaningful margin for a school where three out of four students come from low-income households. The trajectory is the more complicated story: scores peaked in 2018-2019, with math proficiency reaching 81%, before falling sharply during the pandemic (math dropped to 47.7% in 2022). Both subjects have stabilized in the mid-to-high 50s since then, which is solid but well below the pre-pandemic highs. Grade-level data shows the strongest performance in the lower and upper grades (3rd grade math at 80%, 7th-8th grade ELA in the upper 60s), while 6th grade math sits at 41% — a clear weak spot.

Parents are unusually happy here — 96% satisfaction, 98% trust in the principal, and 96% trust in teachers — numbers that consistently outpace district averages and suggest strong family-school communication. Teachers rate instruction quality at 95% and feel safe at 94% (on par with the district), though principal trust among teachers is a softer 85%. The attendance picture is mixed: a 90.3% attendance rate is solid, but chronic absenteeism sits at 65.9% — meaning two of every three students missed enough school to be flagged for chronic absence. Family survey response was only 4% and teacher survey drew just 9 responses, so the climate numbers come from a thin slice of the community.

The student body is overwhelmingly Black (83%) and Hispanic (13%), with a diversity index of 34% — well below the city average and reflecting a much more homogeneous classroom than you'll find in most Brooklyn schools. Fifteen percent of students have IEPs, and the 75% economic need index places this firmly in the high-poverty category. Yet the surrounding Clinton Hill neighborhood tells a different story on paper: median household income near $119,000, a 71.5% college-educated rate, and only 10% poverty. This isn't unusual for a charter school that draws from a wider radius than its immediate block, but the mismatch between the building and the block is worth noting.

Clinton Hill is a settled, well-educated neighborhood where most adults hold a bachelor's degree and roughly two in five households own their homes, with median home values north of $1.1 million. About one in seven households includes children, so the area skews somewhat adult-heavy — a factor that shapes who walks to school versus who commutes. The affluent census profile sits in visible tension with the school's own demographics, which reflects how charters draw families from across district lines rather than solely from their immediate blocks.

The school is a quick 2-minute walk from the C train at Clinton-Washington Avs, with the G train at the same station about 8 minutes away, and the B/Q at 7 Av roughly 11 minutes on foot.
