Launched in 1965, Upward Bound (UB) is one of the oldest and largest of the federal college access programs targeted to low-income students and those who would represent the first-generation of college completers in their families. Currently, UB serves more than 60,000 high school students at a cost of about $4,300 per youth and offers an array of academic and college transition support services. While much about the structure of Upward Bound and the services to be offered are prescribed in legislation, little is currently known about the focus or delivery of these services or the extent to which they vary. This report addresses this information gap by describing the approaches that Upward Bound projects use to provide core program services--advising, tutoring, academic coursework, college exposure, college entrance exam preparation, college application assistance, and financial aid application assistance. Data come from a survey of Upward Bound project directors at institutions (mostly colleges) that host the projects. The primary goal of the survey was to help identify common (or uncommon but promising) practices that could inform program improvement studies that Congress requires the U.S. Department of Education (ED) to conduct. The survey results may also be useful as policymakers consider the upcoming renewal of the Higher Education Act, which authorizes and funds the Upward Bound program. Key findings about the implementation of core services among Upward Bound projects are detailed.
