Giving College Credit Where It Is Due: Advanced Placement Exam Scores and College Outcomes

We implement a regression discontinuity design using the continuous raw Advanced Placement (AP) exam scores, which are mapped into the observed 1–5 integer scores, for over 4.5 million students. Earning higher AP integer scores positively affects college completion and subsequent exam-taking. Specifically, attaining credit-granting integer scores increases the probability that a student will receive a bachelor’s degree within 4 years by 1–2 percentage points per exam. We also find that receiving a score of 3 over a 2 on junior year AP exams causes students to take between 0.06 and 0.14 more AP exams senior year.
