Most public-school rankings sort by raw test scores, which structurally favors wealthy schools. BeatsExpectations adjusts for that. For each US state with sufficient data (38 states currently), we run an ordinary-least-squares regression of composite math + reading proficiency on free-and-reduced-lunch share. The regression gives us a predicted proficiency for every school based on its FRL profile. The difference between actual and predicted, in percentage points, is the school's BeatsExpectations score.
Schools in the top 10% within their state by residual are tagged OUTPERFORMING. Bottom 10% are UNDERPERFORMING. Middle 80% are AS EXPECTED. Thresholds are state-specific because each state uses its own assessment with different rigor and cut scores.
The formula is public, the code is in our public repository, and the score is fully reproducible from the source NCES and state-assessment data. Full methodology, limits, and assumptions →
