Ocean Hill Collegiate Charter School, Brooklyn NY

Original Research by School Decision on Ocean Hill Collegiate Charter School

Ocean Hill Collegiate Charter School is a small, publicly reported charter serving kindergarten through ninth grade in Crown Heights, Brooklyn. The school is part of Uncommon Schools, a charter network, though it has recently undergone structural changes that affect how families enroll and progress through grades.

The school's most recent state testing results show a pattern worth understanding. Third and fourth graders perform well, especially in math, with strong proficiency. Performance softens in middle grades, particularly by seventh and eighth grade. In seventh-grade math, proficiency drops to less than half of students tested. Eighth-grade math results are substantially lower, with only a small fraction meeting proficiency. English language arts follows a similar pattern: upper elementary and sixth graders show solid performance, but seventh and eighth grades show sharp decline. Science testing is limited; fifth grade shows about half the students proficient, and eighth-grade science produced no test results.

Across tested subjects and grades, the school's overall proficiency index places it in the top quartile among Kings County districts, a meaningful strength, though this reflects the relatively stronger elementary results carrying the overall picture. A parent looking at raw seventh and eighth grade numbers may want to look into this further with the school, as the performance gap between lower and upper grades is pronounced.

Enrollment is roughly evenly distributed across grades, with more students in the higher grades tested. About four-fifths of students qualify for free or reduced-price lunch, reflecting a low-income student population. The school's population is predominantly Black, with a substantial Hispanic enrollment and very small Asian and white populations. No data was available on the share of students with disabilities or English learners, which are important details a family may want to ask the school about directly.

A structural detail that affects enrollment: the school recently transitioned from a single K-9 building to a split elementary-middle model. Kindergarten through fourth grade are now served at Uncommon Crown Heights Elementary School at a separate address in Brooklyn, while grades five through eight remain at the Herkimer Street location where the school has long operated. Ninth grade has very few students currently. This means a family enrolling now commits to a multi-campus pathway through middle school before continuing to a high school run by Uncommon elsewhere.

The school also recently adopted Illustrative Math as its mathematics curriculum, replacing an internally developed approach. This represents a shift in how math is taught day to day and is a substantive change worth understanding if your child is already enrolled or considering entry.

The broader Crown Heights neighborhood where the school sits is a densely residential Brooklyn area with a strong sense of community character, vibrant street life, and good transit access. Housing values in the area have been rising. The neighborhood has deep roots in African American culture and community organizations, and it serves as home to many families whose children attend the school.

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.
