A planned vocational guidance program incorporating instructional and counseling components in a community college setting was evaluated. The primary purpose of the program was to improve occupational choice-making of post-high school youth. Three hundred community college students whose verbal and quantitative scores on college entrance examinations fell below the 50th percentile and who had not made firm vocational choices were included in the study. A post-test control group design was implemented which included active and inactive control groups with subjects assigned randomly to five different treatment conditions. Results supported the major hypotheses: (1) reinforcement counseling techniques are effective for improving students' vocational decision-making; (2) Reinforcement counseling techniques are effective for helping students acquire knowledge of sources of personal data and occupational information; (3) simulation materials are effective in improving students vocational decision-making; and, (4) simulation materials are effective for helping students acquire knowledge of sources of occupational information. The experimental program which incorporated testing, counseling, and occupational information services in a coordinated package was found to be effective for improving occupational choice-making of community college youth. An extensive appendix includes data, a typescript of a counseling session, information-gathering instruments, and occupational information. (ET)
