A procedure for determining the effectiveness of counseling programs is suggested in this monograph. Since the procedure is systematic and two-pronged--process and outcome evaluation--it provides information as to the degree of program effectiveness and/or ineffectiveness. A self-correcting system, the procedure's progressive steps illuminate possible errors or ambiguities in previous steps, making it possible to modify the procedures while the evaluation is in process and thus avoid costly problems. The paper also describes evaluation problems and suggests what to do when they arise, and presents a section of recommendations for counselors, supervisors, counselor educators, program developers, and educational researchers.
