This document reviews the literature on barriers faced by first-generation college students that contribute to their low retention and graduation rates. It finds that these students encounter obstacles prior to college enrollment due to a lack of family experience with higher education, as well as difficulties while enrolled in college, such as a lack of college funds and an unwelcoming university climate. The literature shows a need for high schools and universities to understand and address the unique challenges this student population faces in order to improve guidance and support.
