Original Research by School Decision on New York City Geographic District #23
NYC Geographic District #23 is a mid-sized district serving pre-K through 12th grade across a portion of Brooklyn. It enrolls a large student body spanning grades from early childhood through high school, with substantial enrollment in elementary and middle school grades and smaller cohorts at the high school level. The district's student population is predominantly Black, with a substantial Hispanic enrollment and smaller Asian, multiracial, American Indian, and White populations. Free-or-reduced-price lunch data was not available, and counts for students with individualized education plans and English learners were not reported.
The district's academic performance on state assessments shows consistent challenges across tested subjects and grade levels. In elementary grades, proficiency rates in math and English language arts sit in the range of roughly half or below across grades 3 and 4, declining to lower rates by grades 5 through 7. By eighth grade, math proficiency drops sharply. Science proficiency is notably low in tested grades 5 and 8, at roughly one-fifth to one-fifth across those years. A parent looking at these results should understand that they reflect below-median performance compared to other districts in Kings County. The district sits in the bottom quartile countywide on overall proficiency across tested subjects and grades. Participation rates on state assessments generally range from around 70 to 80 percent in core grades, with a substantial drop in eighth-grade math participation, suggesting the testing picture may be incomplete for that cohort.
The district operates a network of about thirty schools across the elementary, middle, and high school spectrum, including traditional public schools, some that serve as arts or sports programs, and secondary schools offering alternative or specialized pathways like Brooklyn Collegiate and Frederick Douglass Academy VII High School. State testing data for individual schools and high school graduation rates were not available in this summary, so a parent evaluating specific buildings or high school outcomes would need to look directly at school-level profiles.
The district has been part of two major curriculum mandates in recent years. Beginning in fall 2023, all elementary schools in District 23 adopted the Into Reading curriculum from Houghton Mifflin Harcourt as part of NYC Reads, the city's systemwide shift toward phonics-based literacy instruction. High schools in the district have moved to the Illustrative Mathematics curriculum for Algebra 1 under NYC Solves, the parallel math standardization mandate; middle school math and reading curriculum mandates are phasing in for all NYC districts by fall 2027. These shifts affect how every child in the district is taught to read and compute, and the teachers union has noted mixed concerns about the math curriculum's alignment with state Regents exams and support for students below grade level. A parent enrolling a child should expect these approaches in the classroom.
In 2023, the city returned discretion over middle and high school admissions to individual district superintendents, ending the pandemic-era random lottery for middle schools and reinstating academic screening. This means District 23's superintendent now sets middle school admissions guidelines and high schools prioritize academically stronger applicants. Unlike many other NYC districts, District 23 has no zoned elementary or middle schools, meaning families have districtwide choice rather than guaranteed neighborhood seats.
The district has experienced sustained enrollment decline over recent years, with elementary and middle school enrollments both down substantially since the earlier part of the past decade. This structural trend can affect school stability, program breadth, and building utilization, matters families weighing the district consider.
