A common justification for state-sponsored merit scholarships like Georgias HOPE program is to promote academic achievement. However, grade-based retention rules encourage other behavioral responses. Using longitudinal records of enrolled undergraduates at the University of Georgia between 1989 and 1997, we estimate the effects of HOPE on course-taking, treating nonresidents as a control group. First, we find that HOPE decreased full-load enrollments and increased course withdrawals among resident freshmen. Second, the scholarships influence on course-taking behavior is concentrated on students whose predicted freshmen GPAs place them on or below the scholarship-retention margin. Third, HOPE substantially increased summer school credits.
