This study sought to determine characteristics of successful and unsuccessful students in a program of adult Indian basic, prevocational, and family life education conducted at the University of Montana. Subjects were 127 Indians from seven Montana reservations. They were divided into three groups; those who successfully completed the program; unsuccessful students who withdrew voluntarily; and unsuccessful students who were terminated for disciplinary reasons. Other variables were home reservation, age, sex, marital status, amount of Indian blood, type of school attended, highest grade completed, and results on the California Achievement Test (CAT), Nelson Reading Test, and General Aptitude Test Battery (GATB). Older enrollees (over 27), and those from the Blackfeet and Crow reservations, were more successful, respectively, than younger enrollees and those from other reservations. Enrollees who had attended Indian schools were less successful than those from mission schools or public schools. Performance on the CAT, the GATB, and the Nelson Reading Test apparently was not related to success or lack thereof. (author/ly)
