Many colleges and universities in the United States offer summer programs for their incoming students. While programs are structured and administered in a variety of ways and target various student populations, the most common type of summer bridge program aims to serve historically underrepresented students and students of low socioeconomic status. The primary goal of these programs is to promote college retention and improve completion rates by providing students with the academic and social tools needed to succeed in college prior to beginning their undergraduate studies. In this article, the authors examine four programs in a single, multicampus public university system. The profiled programs vary in length, course content, and organization. Two of the programs are residential, while the other two allow students to commute from home. Through interviews and review of program materials, the authors found that only one of the campuses studied implements an evaluation process that could be characterized as somewhat complete. In sum, the authors are discouraged by the lack of clear evidence that these particular summer bridge programs are meeting their objectives. The authors' limited study of four programs suggests that there is much work left to be done.
