Original Research by School Decision on Ivy Hill Preparatory Charter School
Ivy Hill Preparatory Charter School is a public charter elementary in East Flatbush, Brooklyn, serving kindergarten through fifth grade. The school opened a few years before the pandemic and has since grown into a complete K-5 program with its first cohorts now moving through the upper elementary grades. It is small by any measure for its grade band, housed on East 57th Street in a residential stretch of central Brooklyn.
The student body is predominantly Black, with a smaller share of Hispanic students and very small numbers from other groups. A substantial majority of enrolled students qualify for free or reduced-price lunch, placing this firmly in the community it serves. Data on students with IEPs and English learners was not available in the records reviewed, which a parent interested in those support structures may want to raise directly with the school.
On the New York State Testing Program, the school's results for the most recent available year show math proficiency running consistently in the mid-fifties across third, fourth, and fifth grade, which is a solid picture. ELA tells a more mixed story: third grade proficiency is notably higher, approaching two-thirds of tested students, while fourth grade drops considerably and fifth grade lands back in the mid-fifties. Science, tested at fifth grade, comes in meaningfully lower than ELA or math. Placed against districts in Kings County using the county comparison set, the school's overall proficiency index sits below the midpoint of that group, though the range among the dozen schools with comparable data spans from well below Ivy Hill to well above. Publicly reported sources note that the school has outperformed state averages in ELA and math in recent years, though the proficiency index position relative to county peers is what the current data supports directly.
One element parents should weigh: the school's charter was renewed by the New York State Board of Regents in 2024, but with its authorized enrollment reduced from the previously approved figure. This means the authorizer approved continued operation while simultaneously constraining future capacity. For families considering enrollment, it suggests a smaller school going forward and is worth asking about in terms of seat availability and the school's plans under that ceiling.
Because Ivy Hill serves only elementary grades, no graduation rate applies and none is reported here. AP coursework and dual-credit pathways are similarly not relevant to a K-5 school. Multi-year trend data was not available, so it is not possible to characterize whether proficiency has moved up or down over time. Discipline data, chronic absenteeism rates, and staffing information were also not present in the records reviewed.
The neighborhood context is dense and walkable. East Flatbush sits within Brooklyn's broader central residential fabric, within reach of the borough's extensive subway network, neighborhood retail, and library branches. Housing near the school runs well above both state and national medians, and rents have continued climbing, making the area expensive relative to most of New York State even as Brooklyn's housing stock continues to expand through new construction in nearby corridors.
For a family specifically looking for a Brooklyn charter school with a defined academic focus in the elementary years, Ivy Hill offers a complete K-5 pathway with a track record now visible in state test data, a tight community demographic, and the grounding of a renewed charter. The fourth-grade ELA dip and the science results at fifth grade are real, and a parent may want to ask the school what it attributes those to and what supports are in place. The enrollment ceiling set at renewal is also a practical consideration, particularly for families with younger children hoping to enter in future years.
