We examine whether virtual advising – college counseling using technology to communicate remotely – increases postsecondary enrollment in selective colleges. We test this approach using a sample of approximately 16,000 high-achieving, low- and middle-income students identified by the College Board and randomly assigned to receive virtual advising from the College Advising Corps. The offer of virtual advising had no impact on overall college enrollment, but increased enrollment in high graduation rate colleges by 2.7 percentage points (5%), with instrumental variable impacts on treated students of 6.1 percentage points. We also find that non-white students who were randomly assigned to a nonwhite adviser exhibited stronger treatment effects.
This paper uses Advanced Placement (AP) exams to examine how receiving college credit in high school alters students’ subsequent human capital investment. Using data from one large state, I link high school students to postsecondary transcripts from in-state, public institutions and estimate causal impacts using a regression discontinuity that compares students with essentially identical AP performance but who receive different offers of college credit. I find that female students who earn credit from STEM exams take higher-level STEM courses, significantly increasing their depth of study, with no observed impacts for males. As a result, the male-female gap in STEM courses taken shrinks by roughly one-third to two-thirds, depending on the outcome studied. Earning non-STEM AP credit increases overall coursework in non-STEM courses and increases the breadth of study across departments. Early credit policies help assist colleges to produce graduates whose skills aligns with commonly cited social or economic priorities, such as developing STEM graduates with stronger skills, particularly among traditionally underrepresented groups.
The College Board sought to reduce barriers in the college application process by minimizing information aggregation costs, encouraging a broad application portfolio, and providing an impetus to start the search process. Some students were offered additional encouragements, such as text message reminders or college application fee waivers. In a randomized control trial with 785,000 low- and middle-income students in the top 50% of the PSAT and SAT distributions, we find no changes in college enrollment patterns, with the exception of a 0.02σ increase in college quality measures for African-American and Hispanic students.
Only half of SAT-takers retake the exam, with even lower retake rates among low income and underrepresented minority (URM) students. We exploit discontinuous jumps in retake probabilities at multiples of 100, driven by left-digit bias, to estimate retaking’s causal effects. Retaking substantially improves SAT scores and increases four-year college enrollment rates, particularly for low income and URM students. Eliminating disparities in retake rates could close up to 10 percent of the income-based gap and up to seven percent of the race-based gap in four-year college enrollment rates of high school graduates.
