Discipline (Suspensions)

| 2024-25 | Redacted | Redacted | Redacted | Redacted |

| 2022-23 | 9 | Redacted | Redacted | 12 |
"Redacted" indicates small counts (1-5) suppressed for privacy. Suspension data reflects systemic patterns as much as individual school decisions. Always consider ENI context.

- 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
