PTA income primarily reflects parent wealth, not school quality. Some schools have very active PTAs while others raise very little.
Discipline (Suspensions)

|---|---|---|---|---|
| 2024-25 | 23 | Redacted | Redacted | 28 |

| 2022-23 | 33 | Redacted | Redacted | 57 |
"Redacted" indicates small counts (1-5) suppressed for privacy. Suspension data reflects systemic patterns as much as individual school decisions. Always consider ENI context.

Data Limitations
- Only 2 years of Impact Score data available (2023-24, 2024-25)
- Impact Score methodology not fully disclosed by NYC DOE
- Cannot determine causation - only patterns and correlations
- No student mobility data (selection effects cannot be ruled out)
- Many schools change category year-over-year
