Leadership Preparatory Canarsie Charter School, Brooklyn NY

Original Research by School Decision on Leadership Preparatory Canarsie Charter School

Leadership Preparatory Canarsie Charter School, now operating under the name Uncommon Canarsie Charter School NYC following a network-wide rebranding, serves students from kindergarten through ninth grade in the Canarsie neighborhood of Brooklyn. The school is a charter operating as its own district, serving a student body of roughly mid-sized enrollment for its grade band. Most students in the school qualify for free or reduced-price lunch, and the enrollment is predominantly Black, with smaller populations of Hispanic students and others. The school's location in southeast Brooklyn places it in a neighborhood with walkable street life and extensive transit access typical of the borough.

In mathematics, the school shows a pattern of strong proficiency in the lower elementary grades, with results in the mid-eighties for grades three and four, then a noticeable dip in grade five before recovering to the low eighties in grade six. Performance declines further in grade seven to a lower level, and testing data for grade eight is not reported. In English language arts, results follow a gentler arc: moderate proficiency in the low fifties for grade three, moving to the low to mid-sixties in grades four and five, rising to the low seventies for grades six and seven, then reaching the high seventies in grade eight. Science results are available only for grade five, where proficiency falls below the midpoint. The patterns across subjects suggest that younger students generally perform better than older ones, with gaps widening as students move into the middle grades.

When positioned against the dozen charter schools serving similar populations within Kings County that report comparable data, this school's overall proficiency index places it in the top quartile among that group, indicating performance above the typical level for similar charter schools in the borough. This positioning reflects strength relative to charter peers, though parents should understand that performance varies notably by grade and subject and that results show momentum dips, particularly around grades five and seven and in science.

The school has no data reported on chronic absenteeism, graduation rates, or special education and English learner populations, gaps that may reflect the school's charter structure, its grade band ending at ninth grade before high school, or data limitations. Parents considering the school may want to inquire directly about classroom practices, how the school supports students through the challenging grade-five and middle-school transitions, and what services exist for students learning English or needing special education support.

Brooklyn itself is undergoing rapid residential development, with strong growth in housing and an economy anchored in healthcare, education, and a growing technology sector. Prospect Park and an extensive library system anchor civic life. The neighborhood surrounding the school is part of a dense urban environment with reliable transit and walkable street life, though like much of Brooklyn it reflects the diversity and varying character of distinct residential and commercial blocks.

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.
