Boys Preparatory Charter School of New York, Bronx NY

Original Research by School Decision on Boys Preparatory Charter School of New York

Boys Preparatory Charter School of New York serves pre-kindergarten through grade 10 in the Bronx, a single-sex charter school with a strong enrollment across grades 3 through 8, and newly expanded high school grades still filling. The school is in the middle of a significant structural change: it was historically a K-8 program, and has been phasing in grades 9 through 12 starting in 2022-23, with grade 12 arriving in the 2025-26 school year. This expansion matters because families can now stay with the school through high school graduation rather than finding a new school after 8th grade. The high school grades are delivered through a joint program called Vertex Partnership Academies, overseen collaboratively by the school's board and another charter network and run by an outside management organization. This means the high school experience differs educationally and organizationally from the lower grades, and the program faces a full renewal review in 2026-27, so its long-term stability is tied to that decision.

The student body is almost entirely economically vulnerable. A substantial majority of students qualify for free or reduced-price lunch. The enrollment is heavily Hispanic and Black, with smaller populations of other racial and ethnic backgrounds. Specific counts for English learners and students with IEPs were not available in the data.

On state assessments, the school shows strong performance in third grade, with roughly nine out of ten students meeting or exceeding proficiency in both math and English language arts. Performance declines as grades progress. By fourth grade, proficiency drops to about seven in ten in math and six in ten in English language arts. By fifth grade, roughly four out of ten students are proficient in both subjects, and in seventh-grade English language arts, proficiency falls to about four in ten. Eighth grade shows a mixed picture: in English language arts about six out of ten students are proficient, but no eighth-grade math data were reported, suggesting that grade level may not have been tested or the cohort is still small. Fifth-grade science shows particularly low proficiency, at about three in ten students, indicating that science instruction or assessment may need attention. The school participates fully in state assessments, with participation rates near or above nine out of ten across all tested grades and subjects.

When compared to other districts in Bronx County, the school's overall proficiency index places it in the top quartile, a meaningful position that reflects strength across tested subjects and grades despite the noted drops at upper levels. The school has no reported graduation rate, which is expected because it does not yet serve a complete high school population; the first cohort completing high school will graduate in 2026.

The school is situated in a rapidly growing borough. The Bronx is experiencing strong housing investment and net new construction concentrated in affordable multifamily buildings. Recent major projects include waterfront transit-oriented development and several affordable-housing initiatives, with the broader Bronx recording hundreds of millions in development investment in recent years. The neighborhood where the school sits, near East 151st Street, sits within the dense South Bronx fabric, walkable and served by subway lines and local commercial corridors.

A parent or resident considering this school should understand the early-grade academic strength, the decline in proficiency at upper grades, and the fact that the school is actively building out its high school program under a new management model. The school offers a pathway through twelfth grade that families might otherwise not have in a charter setting, but the high school's governance and continuation warrant direct conversation with the school about its 2026-27 renewal process.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
