This study examined the impact of social and academic integration on college students' satisfaction and retention in the theoretical context of Tinto. A sample of 378 freshmen from a comprehensive state university responded to a survey. Variables examined included persistence, satisfaction, academic integration, social integration, academic performance, and demographics. Surveys were later matched with students' transcripts and academic records to determine academic status. Data analysis indicated that neither gender, ethnicity, nor age related to student satisfaction. Academic integration, social integration, and academic performance all had positive influences on student satisfaction (with social integration being the most influential factor). Gender, age, and ethnicity also had no impact on student retention, while academic integration, academic performance, and student satisfaction all influenced student retention. Social integration was not significant in students' decisions to stay. Overall, the study partially validated Tinto's theory. Policy implications are discussed. (Contains 39 references.) (SM)
