About
Success Academy Charter School - Bronx 4 is an elementary charter school serving grades K-5, known for its exceptionally strong academic performance. The school consistently achieves ELA and Math proficiency rates (95% and 96% respectively) that are well above citywide medians, often ranking among the top elementary schools in New York State. It serves a student body with a high percentage of economically disadvantaged students and a predominantly Black and Hispanic population, demonstrating outstanding academic outcomes across various subgroups, including students with disabilities and English Language Learners. The school integrates arts, music, chess, and athletics into the daily curriculum. While the academic rigor is widely acknowledged, parent sentiment is mixed; some praise the teachers and student progress, while others express concerns about a very strict and at times punitive environment, particularly regarding administration and support for neurodivergent students. There are also reports of high teacher turnover within the Success Academy network, with staff describing demanding working conditions.

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.
