Original Research by School Decision on Success Academy Charter School - Bronx 4
Success Academy Charter School - Bronx 4 is an elementary charter school in the East Bronx serving kindergarten through fifth grade. The school enrolls a student body that is majority Black and Hispanic, with a substantial share of students qualifying for free or reduced-price lunch. The school is part of a larger Success Academy network, and as of this cycle, state test results show proficiency rates that place it well above the median in Bronx County.
In math, both third and fourth grade students tested at proficiency levels that the state reports as complete mastery, with high participation rates. English language arts proficiency is nearly as strong. Science state testing data was not available for recent years, which is typical for grades in this band, as New York assesses science in grade 4 on a less frequent cycle than math and ELA. The scale scores in both math and ELA fall solidly above state benchmarks, and participation in the state assessments runs consistently high, indicating students are being tested and engaged with the assessment process.
The school's overall proficiency index across tested subjects and grades places it in the top quartile among districts in Bronx County, a strong position reflecting the consistency of proficiency across both tested subjects.
The enrollment is small to mid-sized for an elementary school. Enrollment is distributed fairly evenly across kindergarten through fourth grade, with a negligible number of fifth graders, suggesting the school may be transitioning in its upper grade structure. The school's demographics reflect the Bronx neighborhood in which it sits: the student population is predominantly Black and Hispanic. About four in five students qualify for free or reduced-price lunch.
Limitations in the data prevent a fuller picture of support services. Information on the rate of students receiving special education services or English learner services is not publicly available. A parent may want to look into this further with the school, particularly if their child has an individualized education plan or English learner status, as understanding how the school supports students in these populations bears directly on school choice.
One material fact about the broader network: Success Academy has faced litigation regarding its treatment of students with disabilities. A federal court judgment concluded the network had used harsh disciplinary practices to push out young students with disabilities and ordered a substantial settlement. For families of children with disabilities, this history warrants direct conversation with the school about how it currently serves IEP students and what supports and accommodations are available.
The borough itself is experiencing substantial housing growth and investment. The Bronx recorded significant new housing development in recent years, concentrated in larger affordable projects. Home values and rents in the school's postal code are at or slightly above state and national medians. The neighborhood is walkable, with subway access, and is anchored by major institutions and parks.
Structurally, Success Academy is opening a new K-12 campus in the Bronx in August 2026, meaning families whose children are at Bronx 4 will have the option to stay within the network and borough for middle and high school rather than travel to Success Academy high schools in Brooklyn, Manhattan, or Harlem. This changes the long-term pathway for families considering the full K-12 arc.
