Following the recommendations of Braxton, Sullivan, and Johnson, (1997) to seek explanations for social integration, this study addresses how the fulfillment of college expectations affects social integration. Path analysis is used to examine the effects of having academic and social expectations met on social integration; the effect of social integration on a student's subsequent level of commitment to his/her college or university; and finally the effect of subsequent institutional commitment on the likelihood of student persistence in college. Results from the analyses indicate the fulfillment of students' social expectations for college positively affects both social integration and subsequent institutional commitment. The greater the degree of these, the more likely students will re-enroll in the university.
