Brooklyn Laboratory Charter School

77 Sands Street

At a Glance

A high-school that's shown dramatic academic improvement but struggles with chronic absenteeism in a transit-rich, mixed-safety neighborhood

Best suited for

Families who value the school's academic momentum and are confident they can maintain strong attendance habits despite the high absenteeism environment. Works best for families comfortable with the Downtown Brooklyn location, who prioritize the strong teacher-trust culture, and who want a diverse charter option without screened admissions. Families seeking consistently strong math instruction or robust parent community engagement may want to look at other District 13 options.

What stands out
  • Dramatic one-year academic turnaround (18-point ELA jump, 14-point Math jump)
  • Very high daily attendance (95.6%)
  • Strong teacher-principal trust (85%)
  • Charter school with lottery admissions — no screened entry
  • Serves high-need population (78.7% economic need) with improving outcomes
Things to consider
  • Chronic absenteeism affects nearly 89% of students — this is a major red flag that impacts learning
  • Math scores (36.7%) remain below district average
  • Teacher-reported instruction quality (78%) lags behind district peers (87.6%)
  • Very low family survey response (3%) makes parent voice hard to assess
  • Safety scores in the neighborhood are below average
  • Suspension rate data not provided — discipline climate is a question mark

Based on 2023 data

School SummaryDistrict 13

Among District 13 peer schools (ranked by quality metrics), Brooklyn Lab doesn't appear in the top tier of nearby options like P.S. 011 Purvis J. Behan (96/100) or The Emily Warren Roebling School (91/100). However, its recent academic gains position it differently than static test scores might suggest — it's a school on the upswing rather than a stable underperformer. The chronic absenteeism issue is more severe than most peer schools.

AcademicsImproving

Brooklyn Lab's test scores tell a dramatic story — the school went from 38.7% ELA proficiency in 2022 to 56.6% in 2023, jumping 18 points in one year. That puts them above the District 13 average of 53.1% for ELA. Math improved too, from 22.5% to 36.7%, though that still trails the district average of 45.9%. The overall quality score of 1.87 out of 4 is slightly below the district average of 1.98, but the trajectory suggests the school is closing gaps rather than falling further behind. For a high school serving a population with 78.7% economic need, these gains are meaningful — though parents should note math remains a weaker spot compared to peers.

Culturestrong

The attendance rate of 95.6% is impressive and well above the district average of 89.2%, but the chronic absenteeism rate of 88.5% tells a more complicated story — most students are technically present but missing enough days to matter. Teacher surveys show solid trust in leadership (85% teacher-principal trust, 81% collegial trust) and teachers rate their own instruction quality at 78%, which is below the district average of 87.6%. Parent satisfaction sits at 89%, slightly below the district average of 90.6%, but the family survey response rate was only 3% (15 responses), making it hard to draw strong conclusions about family experience. The vibe appears to be a school where teachers feel supported by leadership, but where chronic absenteeism may be undermining classroom momentum.

Community

With 539 students across grades 9-12, Brooklyn Lab is a mid-sized high school. The student body is 74% Black and 21% Hispanic, with minimal Asian (1%) and White (2%) representation — this is a predominantly Black school in a neighborhood that's 73.3% college-educated but only 15.1% families with children. The diversity index of 44% is relatively low, reflecting the homogeneous demographics. Twenty-seven percent of students have IEPs, and the economic need index of 78.7% indicates significant poverty — this is a high-need school serving students from households facing economic challenges, despite being in a neighborhood that reads as affluent on many metrics.

NeighborhoodDowntown Brooklyn-DUMBO-Boerum Hill

The Downtown Brooklyn-DUMBO-Boerum Hill area is a study in contrasts: extremely high transit access (98th percentile) and education orientation (85th percentile), but concerning safety scores (21st percentile) and low family density (only 15% households with children). The median home value of $1.46 million and household income of $150,272 suggest affluence, yet 15.5% poverty rate indicates real economic struggle exists. There's a mismatch between the neighborhood's professional veneer and the families Brooklyn Lab actually serves. Parents should factor in the safety data — crime density and collision rates are elevated — when considering this location.

Excellent transit access makes this highly reachable by subway from across Brooklyn and Manhattan. Walking conditions are mixed due to traffic and urban density — families from further afield may find the commute manageable given the strong transit options.
