Millions of high school students take Advanced Placement (AP) courses, which can provide college credit. Using nationally representative data, I identify a diverse set of higher education outcomes that are related to receipt of AP college credit. Institution fixed effects regression reduces bias associated with varying AP credit policies and student sorting across higher education. Results indicate college credits earned in high school are related to reduced time to degree, double majoring, and taking more advanced coursework. Bounding exercises suggest the time to degree and double major outcomes are not likely driven by bias from unobserved student characteristics. Policies used to support earning college credits while in high school appear to enhance undergraduate education and may accelerate time to degree.
