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
