About these rankings
These tables use the most recent NCES Common Core of Data (2024-25) for enrollment, demographics, and staffing, and state-native assessment data (typically 2023-24 or 2024-25) for proficiency. BeatsExpectations is computed via per-state ordinary-least-squares regression of composite proficiency on free-and-reduced-lunch share. Full methodology.
