The effects of three treatment procedures on college students' vocational development were investigated. These were: (a) experimental guidancesubjects participated in a 5-week vocational guidance program; (b) individual counseling-subjects received individual counseling; and (c) controlsubjects received no treatment. Evaluation was based on measured vocational development and on student assessment of assistance received using multiple linear regression techniques. The experimental treatment was more effective in increasing vocational development than either the individual counseling or control treatments, and individual counseling was more effective than the control treatment. No differences were found among groups in regard to individual counselors, sex of students, or in student counseling assessments.
