Original Research by School Decision on Success Academy Charter School-harlem 4
Success Academy Charter School-Harlem 4 is a small elementary charter school serving kindergarten through fourth grade in New York County. The enrollment is modest, with approximately two hundred students distributed across five grades. The student body is predominantly Black and Hispanic, with smaller numbers of Asian, White, and multiracial students. Specific data on free- or reduced-price lunch eligibility, English learners, and students with IEPs were not available in the school's reporting.
The school is part of the Success Academy network, a charter organization operating multiple schools across New York City. This network affiliation shapes the academic experience in concrete ways. In the 2024-25 school year, Success Academy implemented a network-wide curriculum redesign called the "Education Moonshot," which was reverse-engineered from college-preparedness endpoints and rolled out across all grades K-12. For families at Harlem 4, this means the elementary curriculum they encounter is designed to feed coherently into the network's middle and high schools, creating continuity across the full K-12 span rather than isolated grade-band instruction.
The network also expanded its high school options in 2026 by opening a new Bronx K-12 campus. Families enrolling at Harlem 4 now have four possible high school pathways within the Success Academy system: the existing schools in Brooklyn, Harlem, and Manhattan, plus the new Bronx location. For a parent or guardian considering this school, the charter affiliation means a defined academic pipeline and a single set of expectations across multiple grade levels, though also less flexibility if the school's approach does not align with a family's needs.
State assessment data and a proficiency index were not available. The school does not report a graduation rate, which is expected given that it serves only elementary grades and does not extend to high school completion.
Among New York County's districts, chronic absenteeism at Harlem 4 sits in the top quartile, meaning the school's absentee rate is lower than that of the majority of other districts in the county. Per-pupil current spending is in the lower range for the county, reflecting the school's elementary-only model and the charter sector's cost structure.
The school is small and elementary-focused, drawing a neighborhood population from Harlem. A parent weighing this option should understand it as an entry point into a network with a defined long-term academic strategy and shared high school outcomes, not an isolated elementary choice. The lack of published proficiency data means a parent may want to look directly into the school's academic results and approach with the school itself or through publicly available Success Academy reporting.
