How this is scored→

What stands out

  • A 100/100 program richness score backed by an unusually deep arts catalog — African Dance, Jazz Band, Orchestra, Musical Theater, Studio Art, and more alongside coding and STEM
  • Zero suspensions in 2023-24 with a formal Restorative Circles program, signaling a genuinely restorative discipline culture rather than a permissive one
  • PTA fundraising of roughly $660 per student — about a third more than the District 15 average — evidence of unusually engaged families
  • Test scores comfortably above district averages in both ELA and math
  • ELL Support alongside 27% IEP enrollment shows the school is set up to serve a wide range of learners despite a relatively affluent student body

Things to consider

  • Chronic absenteeism at 88.5% is a striking figure that deserves a direct conversation with the school about what it means and how it's being addressed
  • Teacher-reported instruction quality (82%) trails the district average (89%) by seven points — worth asking the principal about teacher retention and curriculum support
  • Test scores have not returned to pre-pandemic levels, when proficiency was routinely in the mid-80s
  • Eighth-grade math proficiency at 63.4% lags the school's overall math average by roughly 6 points, suggesting a slip during the final year before high school
  • Parent satisfaction (88%) is five points below the District 15 average (93%), even though trust measures are strong — a nuance worth exploring

Based on 2024-25 data

School SummaryDistrict 15

Within District 15 — a district stacked with strong middle schools — the Exploratory sits comfortably above average on academics and most climate indicators, but it doesn't crack the top tier of peers like the Beacon School, P.S. 39, or P.S. 321. It's a solid, distinctive option rather than a feeder for selective programs.

Academics

Steady

Both ELA (70.8%) and math (69.9%) run about 5–7 points above the District 15 averages of 65.5% and 63.3%, putting the school in the upper tier of the district but well short of its pre-pandemic self. From 2016 to 2019, the school posted ELA and math proficiency in the 82–87% range; the post-pandemic rebound has plateaued in the high 60s to mid 70s. By grade, seventh graders are the strongest cohort (ELA 72.5%, math 77.6%), while eighth-grade math at 63.4% drags down the school's overall math average — worth asking about if your child is entering 8th grade.

Culture

concerning

The day-to-day feel is a mixed picture. On one side: zero suspensions last year (down from six the year prior), a formal Restorative Circles program, and parent-principal trust at 98% — the kind of climate where families feel heard and discipline is handled without removing kids from class. On the other side: teacher-reported instruction quality is 82%, seven points below the district's 89%, and chronic absenteeism sits at an eye-catching 88.5% — a figure worth pressing the school on directly, since it sits oddly against an otherwise strong 95% daily attendance rate and high trust scores.

Community

The student body is 44% White, 23% Hispanic, 15% Black, and 12% Asian — Whiter than Brooklyn as a whole and a pretty clear reflection of the surrounding neighborhood, where the median household income tops $150,000 and over 73% of adults hold a bachelor's degree. The economic need index of 43.7% is moderate, well below the citywide norm, signaling a largely middle- and upper-middle-class community. With 27% of students classified as having IEPs and a formal ELL support program, the school serves a meaningfully wide range of learners despite its relatively affluent profile.

Neighborhood

Downtown Brooklyn-DUMBO-Boerum Hill

Downtown Brooklyn-DUMBO-Boerum Hill is one of Brooklyn's wealthiest and most transit-connected neighborhoods, with a typical home valued above $1.4 million and a median household income north of $150,000. Most families rent — only about a quarter of households own their homes — and three-quarters of adults have a bachelor's degree. The area draws professionals and young families who prize walkability and quick access to Manhattan.

One of the easiest school commutes in the city — the Atlantic Av-Barclays Ctr station complex is a 2- to 4-minute walk from the school, putting the D, N, R, 2, 3, 4, 5, B, and Q lines at the front door.
