This study extended earlier research based on Tinto's 1975 model of student college attrition by investigating patterns of student social and academic integration across institutional types. This study found that different college types were characterized by different patterns of student participation in the social and academic life of the college. Personal characteristics and overall climate associated with each institutional type explained statistically significant but modest amounts of the variance in student participation in specific campus activities that help define campus life. Moreover, several personal characteristics were related to students' campus behavior differently across institutional types. Findings are discussed in terms of their implications for student recruitment and retention.
