RT Journal Article SR Electronic T1 College Summer School JF Journal of Human Resources FD University of Wisconsin Press SP 1231 OP 1259 DO 10.3368/jhr.0122-12151R1 VO 61 IS 4 A1 Brownback, Andy A1 Sadoff, Sally YR 2026 UL http://jhr.uwpress.org/content/61/4/1231.abstract AB We experimentally examine whether a policy targeting college summer school enrollment can accelerate degree progress and completion. We randomly assign summer scholarships to community college students and find a large impact on degree acceleration, increasing graduation within one year of the intervention by 32 percent and transfers to four-year colleges by 58 percent. We elicit preferences for the scholarships and find substantial treatment effects on enrollment, graduation, and transfer among students with a preference against summer school. These results suggest that many more students could benefit from summer school than the minority who currently enroll.
