At a Glance
A growing charter school in East Harlem where early grades are still finding their footing but middle schoolers are showing strong results
Families in East Harlem who value strong parent-school relationships and a smaller learning environment, and who are comfortable with a school that's still building its academic program. Families with middle schoolers may find the most success here given the stronger performance in grades 6-8. Parents should be prepared to actively support attendance and homework completion given the chronic absenteeism rates, and should weigh whether the charter model (lottery admissions, different governance) fits their preferences.
- Strong parent-principal trust (100%) and parent-teacher trust (97%) — families feel heard and connected
- Middle school performance (especially 8th grade at 61.9% in both subjects) significantly outpaces district averages
- Small school with 210 students and 20-person class sizes — more individualized attention possible
- Charter school with lottery admissions, offering a different model than zoned public schools
- Test scores remain volatile year-over-year and younger grades haven't shown the same improvement as middle school
- Attendance and chronic absenteeism are significant concerns (32.8%) and may impact classroom learning
- Very low family survey response rate (4%) means parent satisfaction data may not represent the full community
- Math scores still lag behind district averages despite recent improvement
- Teacher-reported instruction quality (68.6%) is notably below district average — a potential red flag
- The school is still relatively young (now serving through 9th grade) and may continue to evolve
Based on 2024-2025 data
School SummaryDistrict 4
Among District 4 peer schools, Harbor Science ranks below established charter success schools like Tag Young Scholars (97/100) and Success Academy Harlem 3 (95/100), but it also serves a high-need population. The school's overall score of 1.85/4 sits just below the district average of 1.90, placing it in the middle tier of Manhattan District 4 schools — not a top performer but not at the bottom either.
The school's 2025 scores show a split picture: ELA at 51.8% edges above the district average of 49.8%, while math at 40.5% falls below the district's 45.2%. Looking at the longer trend, there's been real improvement from the 2022-2024 period when math dipped as low as 17.6% and ELA hovered around 35-44%. The standout data is in middle school — 8th graders are performing at 61.9% in both subjects, and 6th grade ELA hits 61.9%, suggesting the upper grades have figured something out. However, the younger grades haven't yet shown the same trajectory, and the school is still working toward consistency across all grade levels.
Parent trust here is exceptional — 97% of families trust teachers, and a full 100% trust the principal, which is remarkable. That said, only 4% of families responded to the survey, so take those numbers with a grain of salt. Teacher-reported instruction quality (68.6%) falls below the district average of 87%, which may reflect the challenges of teaching in a school still building its academic program. Attendance is a real concern at 82.2% versus the district's 87.7%, with 32.8% of students chronically absent — notably higher for male students (37.7%) than female (26.2%). Parents should know that chronic absenteeism is a schoolwide issue that likely affects classroom momentum.
This is a high-need community: 87% of students qualify for free lunch, and 29% have IEPs. The student body is predominantly Black (48%) and Hispanic (47%), reflecting the neighborhood demographics. With only 210 students total and an average class size of 20, the school is small and intimate — families looking for a tighter community may find that appealing, though the small size also means limited extracurricular options.
East Harlem is a densely populated, family-focused neighborhood with strong public transit (80th percentile) but real safety concerns — the safety score of 12.26 places it in a lower percentile. The area has a high poverty rate (29.5%) and very low homeownership (7.8%), meaning most families rent. The education orientation score of 66% suggests this is a neighborhood where families are choosing to live for school access. Environmental health indicators show some concerns (elevated asthma rates, elevated lead risk), which is worth knowing for families with health sensitivities.
Well-served by transit with high walkability due to Manhattan density — families can typically reach the school via subway or bus without difficulty
