Original Research by School Decision on Brooklyn Laboratory Charter School
Brooklyn Laboratory Charter School is a high school serving grades nine through twelve in Kings County, with an enrollment of just over half a thousand students. The school is predominantly Black, with a substantial Hispanic enrollment and very small numbers of white, Asian, and other students represented.
The school recently underwent a significant structural change. It converted from a combined middle-and-high school serving grades six through twelve to a high-school-only program, eliminating its middle grades. This means families with younger children seeking continuity from sixth grade will need to look to other schools. The conversion took effect in the 2023-24 school year with Regents approval. For families with high school students already in Brooklyn, this shift means the school is now focused entirely on secondary education and college preparation.
The school's charter was renewed by the Board of Regents for a four-year term in 2025, providing continuity of operation. This renewal signals that the school met renewal criteria and will remain in place for families considering enrollment.
State testing data and graduation rates were not available in the data reviewed, so a parent seeking to understand academic outcomes and completion rates would need to request that information directly from the school or consult state reporting sources. The school does publicly report a chronic absenteeism rate, and that rate places it below the midpoint among Kings County's districts, meaning absenteeism is a somewhat higher concern here than in other county districts. A parent may want to look into the school's attendance practices and supports further with the administration.
Per-pupil spending at the school runs in the upper range among Kings County districts, reflecting the resource intensity of charter operations and college-prep programming.
The school recently ended remote learning options and faced a funding decline as federal pandemic relief funds expired in 2024, with enrollment dropping as a result. This transition from hybrid to in-person-only means families should confirm the school's current operational model matches their needs. The funding loss may also affect program breadth and resources going forward, an area a parent may want to discuss with the school directly.
The school operates as a single-school district, meaning there are no other buildings or programs within its governance structure. Enrollment data show the high school classes are roughly balanced, with the strongest participation in grades nine and twelve. The tenth and eleventh grade cohorts are slightly smaller.
