Effects of a college access program for youth underrepresented in higher education: A randomized experiment

This article describes EXCEL, a program that encourages youth underrepresented in higher education to enroll in higher education, specifically at the sponsoring university. Eighty-three eighth grade students with GPA of B and above and standardized test scores at grade level or above were randomly assigned to the program or to a control group. The program guaranteed a scholarship to the sponsoring university and provided enrichment activities throughout high school. Program students were more likely to enroll at the sponsoring university than were control students. However, program and control students enrolled in higher education at rates that did not differ significantly. No differences were detected in self-esteem or high school GPA. Program students desired more education than control students. The results suggest that scholarship incentive and support programs that target average to above average achieving students in the eighth grade may not raise the overall number of aspiring minority youth attending college, but may be useful to specific universities to raise their minority enrollment.
