This study used weekly conversations with 25 freshmen at Boise (Idaho) State University (BSU) and analyses of students' journal entries to examine reasons for BSU freshmen leaving school during or after their freshman year. The 13 students who were successful (reenrolled in the spring and following fall semesters and maintained satisfactory grades) represented all types of students. However, for older successful students a supportive family environment appeared to be critical. For younger successful students, getting involved with campus activities, seeing the value of an education, and enjoying learning seemed to be important factors. Unsuccessful students fell into two groups: one group consisted of women with children who were trying to go to school but lacked support. The other group consisted of 18-year-olds who appeared developmentally unprepared for college. Other "at risk" students (those who reenrolled but had very poor grades) generally appeared to have to try harder to get the same grades others got with less effort. Results indicate that retention efforts must focus on meeting the diverse needs of various student groups. (DB)
