Evaluating the effectiveness of career guidance programs is a complex process, and few comprehensive models for evaluating such programs exist. Evaluation of career guidance programs has been hampered by the myth that program outcomes are uniform and monolithic. Findings from studies of attribute treatment interactions have revealed only a few obvious attributes that appear to interact with differential treatments (including such obvious variables as gender, ethnic/racial group, and chronological age). Where interactions have been found, they have been complex with barely significant effects or are confounded with main effects, which makes them difficult to interpret. Substituting person-oriented parameters for attribute treatment interactions changes the "inverted" pyramid of policy, program, and person to a "verted" pyramid with the person at the apex, program at the intermediate point, and policy at the base or foundation. This person-oriented approach to evaluating career guidance programs can be implemented through reverse programming. The conceptual framework of reverse programming encompasses three topics: career by objectives, a systems approach to career counseling, and evaluation models and methods. A systems approach to career guidance is possible because of the quick data processing that is attainable by using synchronized computer and peripheral technology. (MN)
