About
Success Academy Charter School - Flatbush is an elementary school in Brooklyn, serving students in grades K-5. It is widely recognized for its exceptionally strong academic performance, with ELA and Math proficiency rates significantly exceeding citywide averages, placing it among the top-performing schools in New York City. The school also reports a very low suspension rate, suggesting a highly structured and disciplined environment. Parents often commend the school's rigorous and fast-paced curriculum, which thoughtfully integrates subjects like science, chess, and the arts into the daily schedule. Many families express profound appreciation for the educational opportunities and the school's emphasis on character development. However, the school's demanding academic expectations and a "no-excuses" approach to discipline have generated mixed feedback. Some parents and former staff describe a high-pressure environment with strict behavioral codes and intense academic focus, which may not be suitable for every student. Concerns have also been raised regarding staff support and high turnover rates.

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.
