About

Success Academy Charter School - Harlem 4 is a K-8 charter school known for its exceptionally strong academic performance, consistently achieving proficiency rates in English Language Arts (87%) and Math (96%) that are well above the citywide 75th percentile. The school is part of the Success Academy network, recognized for its structured academic approach, high expectations, and data-driven instruction. Parents often praise the rigorous curriculum and the dedication of teachers, noting significant academic growth in their children. However, some families and observers describe the school's environment as highly demanding and strict, with a strong emphasis on discipline that can lead to a high-pressure experience for students. The school integrates arts, music, chess, and athletics into the regular school day, and students are required to wear uniforms. It shares a building with other schools.
