This NCPR working paper reports findings from a study that used a detailed dataset and a regression discontinuity design to identify the causal effect of remediation on the educational outcomes of nearly 100,000 college students in Florida. The paper also discusses concerns about endogenous sorting around the policy cutoff, which poses a threat to the assumptions of the regression discontinuity model in multiple research contexts.
