Little is known about migrant students' college access. Outreach programs serving such students rarely track their participants' postsecondary trajectories, nor do they compare participants' college access outcomes with those of similar students. This study examines the California public college application, acceptance, and enrollment patterns of participants in the Migrant Student Leadership Institute, a residential college preparatory summer program serving migrant students in California. Findings indicate that program participants apply to University of California campuses at a higher rate than non-participants with similar academic and school background characteristics. Evaluation evidence indicates that interventions like the MSLI contribute to improved college-going outcomes. (Contains 5 tables.)
