This publication addresses one of the significant and critical characteristics of an effective rehabilitation counselor: the awareness of the various kinds of strategies and information that are available to him and the client for decisionmaking. Five sections are included after the introductory section, which briefly discusses evaluation of rehabilitation potential, the preliminary diagnostic study, the thorough diagnostic study, and extended evaluation of the client. Sections are titled Psychological Testing and Evaluation of Rehabilitation Potential, How to Develop and Establish a Training Program on Psychological Testing, The Counselor's Checklist for Reviewing Vocational Evaluation Programs, The Work Sample Approach in Vocational Evaluation, and Counselor Resources for Vocational Evaluation. The appendix provides a list of 44 questions which can be used as a checklist for the vocational evaluator, the vocational evaluation program, and the vocational evaluation process. (SH)
