About
Achievement First Brownsville Charter School is a K-12 institution in Brooklyn, operating with a mission to prepare students for college and career while fostering self-knowledge and purpose. Academically, the school's elementary and middle school students perform at or slightly above citywide medians in ELA and Math proficiency. However, a very low percentage of students participate in accelerated coursework, suggesting limited advanced academic opportunities. For high school, official data indicates a very low 4-year graduation rate, a significant concern, though other sources report substantially higher rates. Despite this, the college enrollment rate for graduates is a notable strength, well above the citywide 75th percentile. The school serves a student body with high economic need. Parents and students describe a rigorous academic program, with some praising school spirit and dedicated elementary teachers. However, concerns have been raised regarding a perceived rigid environment, high teacher turnover, and a lack of diverse extracurricular activities. Some students also report a negative peer culture and safety concerns in the surrounding area after school hours.

Financials

Charter schools manage their own budgets rather than receiving a school allocation from the DOE, so the staffing and supplies breakdown the DOE publishes for district schools is not published for this school.
