At a Glance
A small zoned elementary school serving a high-need East Harlem neighborhood, where test scores are climbing but chronic absenteeism remains a daily challenge
Families zoned for this East Harlem area who prioritize a small, relational school with strong teacher trust and excellent discipline over top test scores. Best fits families who believe in the school's direction, can support homework and reading at home to counteract the academic lag, and are comfortable with a school where nearly all families face economic hardship. Families seeking higher test scores or more diverse peer groups would likely look to district charters or screened schools instead.

- High teacher-reported instruction quality (87%) despite lower test scores

- Chronic absenteeism is very high at 40.8%, nearly double the district average
- Teacher-reported safety (71%) is well below district average (87%) — families should ask the school what's being done
- Grade-level performance is uneven: 5th grade strong in ELA (42%) but 4th grade very low (13%)
- Economically homogeneous student body — 91% economic need means limited socioeconomic diversity
- Parent satisfaction (86%) runs slightly below the district average (91%)
Based on 2024-2025 data
School SummaryDistrict 4
Mosaic Preparatory Academy sits near the bottom of District 4, which itself includes many high-performing charters and screened schools. Peer schools like Tag Young Scholars (97/100) and Success Academy Harlem 3 (95/100) dramatically outperform Mosaic on state tests. Among district zoned schools serving similar populations, Mosaic's zero-suspension record and strong trust scores are genuine differentiators, but its test scores and attendance rates are areas where peers often do better. The school's 0.94 overall score on the city grading system places it well below the district average of 1.9.
Mosaic's state test scores — 27% ELA and 20% math — place it roughly halfway between the citywide floor and the District 4 average of roughly 50% in both subjects. The school has climbed back from a pandemic nadir (4.8% ELA in 2022) but still trails its district peers significantly. Grade-level patterns are telling: 5th graders perform notably stronger in ELA (42%) while 4th graders lag (13%), suggesting uneven instructional coherence across grades. With an overall quality score of 0.94 out of 4, the school sits in the bottom tier of district performers. Teacher-reported instruction quality is high at 87%, which suggests classroom instruction may be better than test scores indicate — a disconnect worth investigating for families.
The school's climate data reveals a paradox: families and teachers report strong mutual trust (89% parent-teacher and parent-principal trust, 86% teacher collegial trust), yet teacher-reported safety scores drop to 71% — notably below the district average of 87%. This safety perception gap is worth noting. Attendance is a real concern: the school logs an 85.3% attendance rate with a steep 40.8% chronic absenteeism rate, meaning roughly 4 in 10 students miss at least a month of school. Chronic absenteeism hits Black students hardest at 53%, compared to 28% for Hispanic students — a disparity the school likely needs to address. On the positive side, Mosaic has maintained zero suspensions for three consecutive years, a sharp decline from two suspensions in 2021-22. The day-to-day feel appears collaborative and trusting, though safety concerns and chronic absenteeism cloud the picture.
Mosaic serves 207 students in a school that reflects its East Harlem neighborhood's demographics: roughly 44% Black, 46% Hispanic, with tiny Asian and white populations and 4% Native American enrollment. A quarter of students (26%) have IEPs, well above typical elementary schools. The economic need index of 91.4% indicates nearly every family qualifies for free or reduced lunch. With a diversity index of 59% and a student body that's predominantly Black and Hispanic in a low-income, high-density family neighborhood, the school captures the community it serves — though the lack of socioeconomic or racial diversity within the school itself is notable.
East Harlem is a dense, transit-rich, working-class neighborhood with significant challenges. Safety scores are low (12/100) and environmental health indicators show elevated lead rates and asthma emergency department visits — factors that affect student wellbeing. That said, the neighborhood boasts excellent transit access (80/100) and is extremely family-dense (96/100), meaning families with children are everywhere. The area is predominantly rental (92% renters, 8% homeowners), with a median household income around $44,000 and 30% poverty rate. There's a community feel here, with culturally rich local businesses and nearby parks, though parents should be aware of the environmental health context.
East Harlem is highly walkable with strong subway access. Most zoned families walk or take public transit — the area is dense and compact. However, parents should factor in the neighborhood's safety perceptions when considering commutes, particularly for younger children walking alone.
