This monograph reports a study by the Education Improvement Program of the Southern Association of Colleges and Schools to investigate the relative effectiveness of several delivery systems for occupational information to minority students. Part 1 overviews the need to facilitate vocational guidance and career development of minority students and cites pertinent literature. Part 2 describes the purpose and methods of the study to investigate and compare three specific methods of disseminating occupational information to bring about changes in career choice attitudes and competencies among black college students from low socio-economic background--career logs, career simulations, and written occupational briefs. Results of testing treatment and control groups (226 black college freshmen enrolled in freshmen development programs at predominantly black senior colleges) confirmed that career planning experiences and occupational explorations can be beneficial in raising career maturity. All three methods were useful, and students who received occupational information generally scored higher on career maturity indexes. Providing occupational information was found to promote vocational development and growth of individuals from low socio-economic backgrounds. Part 3 overviews the topic and provides a summary, conclusions, and implications. (YLB)
