In this paper we investigate the impact of a statewide program aimed at better aligning K-12 to higher education and improving college readiness. We replicate an earlier study focused on the effects of this program at one campus by employing detailed administrative data on the census of California students that enroll at all twenty-three campuses of the California State University (CSU) system. We evaluate whether the program has reduced remediation rates at CSU statewide and investigate whether program effects differ by student background. We find that participation in the Early Assessment Program reduces the average student’s probability of needing remediation at California State University by about 2-3 percentage points overall. Investigating heterogeneous treatment effects, we find the program effects are largely concentrated among students at the margin of remediation risk.
