Achievement First Endeavor Charter School

About

Achievement First Endeavor Charter School, a K-8 charter school in Brooklyn's Clinton Hill neighborhood, is part of the Achievement First network, known for its highly structured educational approach. The school occupies a transformed factory building, featuring bright classrooms, science labs, a skylit cafeteria, a gymnasium, and two rooftop play spaces. Academically, students demonstrate proficiency in English Language Arts and Math, with scores slightly above the citywide median for elementary and middle school grades. Parent sentiment from recent official surveys is overwhelmingly positive, indicating strong satisfaction with the school environment and family relationships. However, online reviews present a more mixed picture, with some parents and students describing a demanding environment, concerns about strict discipline, and instances of bullying. There have also been mentions of challenges in supporting students with special needs and a perceived lack of teacher assistance in larger classrooms. The school emphasizes a rigorous college preparatory education for its K-8 students, though the percentage of students in accelerated coursework is notably low compared to citywide benchmarks. Admission to this charter school is through a lottery system.
