Original Research by School Decision on Boys Preparatory Charter School of New York
Boys Preparatory Charter School of New York is a single-sex, all-boys charter school operating across Bronx County serving pre-kindergarten through tenth grade, with a grade pattern that expands through grade twelve over the coming years. The school currently enrolls a student body that is roughly equally divided between Black and Hispanic students, with very small representation of other racial and ethnic groups. Enrollment sits at just over six hundred students across the grade band, with the lower elementary grades (kindergarten through second) substantially smaller than the middle elementary and middle school grades, which have reached the school's target capacity.
The school's defining recent change is its expansion from a traditional K-8 model to a full high school program. For decades it functioned as a middle school pathway, meaning families who chose Boys Preparatory had to plan for their child to transfer elsewhere after eighth grade. Beginning in the 2022-23 school year, the school began adding high school grades one per year—grade 9 first, then grade 10, with grades 11 and 12 to follow. This shift means a family enrolling now can remain at the school through graduation, a substantial structural change that reshapes how the school fits into a family's longer educational planning.
The high school component, however, operates under a different model than the lower grades. The ninth and tenth grade students are part of Vertex Partnership Academies, a joint high school program governed jointly by the boards of Brilla Schools and Public Prep Academies and run by an outside management organization. This represents a meaningful shift in educational governance and approach for upper-grade students. Parents considering Boys Preparatory for the full span through high school should understand that the ninth and tenth grade experience, and the grades 11 and 12 experience when they arrive, will differ from the model in the younger grades. Additionally, this joint high school program faces its own full renewal review in the 2026-27 school year, which means its continuation is subject to separate authorization.
State testing data for the school was not available, so the academic performance picture cannot be drawn from proficiency measures. The school's chronic absenteeism rate sits below the midpoint among Bronx County's districts, a moderately strong position relative to peers in the county. Per-pupil spending at the school is in the upper range among county districts, reflecting the resources devoted to its operations.
Data on free-or-reduced-price lunch eligibility, special education enrollment, and English learner populations were not provided, so the economic and academic support needs of the student body cannot be characterized from the available information. A parent interested in understanding the school's student support infrastructure and the composition of its student body more fully may want to reach out to the school directly with those specific questions.
