Notes: Standard errors robust to clustering at the school level shown in parentheses (*P < 0.05). All models include student covariates, grade-by-year, and school effects. Covariates include lagged z-score, gender, race/ethnicity, low income status, LEP, immigrant, and special education status. Low income is measured by eligibility for free or reduced price meals or enrollment in a Universal Free Meal school. Excludes charter school students and students attending citywide special education schools (District 75).
