Information was collected from 28 Chicano, 42 Chicana, 36 non-Chicano, and 52 non-Chicana students to identify reasons for Chicana attrition from the University of Southern Colorado. Information was also collected from 14 Chicanas who had already dropped out of college. Most of the data were collected at registration for spring semester, 1980. The study followed the initial sample through the semester and then determined their status as dropouts or persisters at the beginning of the subsequent semester. Demographic variables, academic background variables, and psychosocial variables were identified for investigation. Several psychosocial variables were identified that successfully discriminated males from females and Chicanos from non-Chicanos. Ethnic differences existed primarily in the areas of academic self-esteem and perceived treatment by teachers. Sex differences were represented by variables pertaining to social relationships and friends' academic expectations. Sex and ethnicity differences were found in the areas of parental income and family dependence. None of the variables were more than moderately associated with dropout status. There were no consistent findings among the dropouts on their feelings about the variables, but more than half mentioned finances as a reason for leaving. Appendices include the primary survey instrument, the dropout interview, descriptive findings, findings, and a literature review. (CM)
