Students at Indiana University, Bloomington who were enrolled in the University Division in the 1979 spring or summer semester but who did not reenroll in the 1979 fall semester were surveyed. The 687 responding students were classified as academic dismissals (32 percent), voluntary withdrawals, (51 percent), or intercampus transfers (17 percent), and were compared on selected academic and biographic measures. Voluntary withdrawal subcategories were further identified: dropouts who had not enrolled at another school and transfers who had enrolled at another school. Females were significantly higher than males in grade point average, high school rank, and cumulative hours. Males were higher on Scholastic Aptitude Scores, but only for math was the difference significant. For the three main types of student categories, information is presented on the following variables: race, marital status, place of residence, entering semester, first semester attended, last semester attended, housing arrangement, class standing, and whether the student's major was declared. The 10 major reasons for leaving the university are identified for each group. Among the reasons cited for students who experienced academic dismissal were low grades, dissatisfaction with academic performance and personal achievement, and personal adjustment problems. Voluntary withdrawal dropouts cited uncertainty of career choice and academic goals, and personal adjustment problems; voluntary withdrawal transfer students cited unavailability of desired major/program or goals not having been achieved; and the intercampus transfers cited low grades, dissatisfaction with academic performance, and personal adjustment problems. Followup results and a questionnaire are included. (SW)
