Abstract
This study investigated the effect of grade retention in elementary school on dropping out of school by age 16. Participants were 538 (54% males) ethnically diverse, academically at-risk students recruited from Texas schools into a longitudinal study when they were in first grade (mean age=6.58). Propensity score weighting successfully equated the 171 retained students and the 367 continuously promoted students on 65 covariates assessed in grade 1. Fifty-one students dropped out of school by age 16 and 487 persisted. Retention (vs. promotion) led to an increased early dropout rate (odds ratio=1.68), even after controlling for 65 covariates associated with school achievement, retention, or both. Implications of findings for dropout prevention and grade retention policies are discussed.
