Student effort response to shifts in university admission policies

Policies which change the incentives students face are important levers for policymakers to improve learning. I study a statewide postsecondary admissions policy in North Carolina which introduces minimum admission standards for students wishing to attend college in-state. Regression discontinuity estimates show that high school students respond by increasing GPA and decreasing absences and suspensions, suggesting increased engagement. However, I find that the boost in GPA is driven by students substituting away from demanding coursework. Finally, I document stark heterogeneity of response across demographics, as minority and less affluent students have higher effort allocations but do not engage in strategic course-taking.
