This publication is intended to provide rehabilitation professionals with information about and structure for conducting the client information-gathering process prior to beginning vocational evaluation services. It can be divided into two major parts: (1) presentation of information and a model for structuring the information-gathering process and (2) demonstration of analysis of the information collected to develop "referral" or evaluation criteria. A section on gathering information suggests possible questions for seven major information categories found most useful in vocational planning--demographic-identifying information, work history, education and training, personal and social adjustment, disability, vocational interests and goals, and job-seeking experience. Other topics include client understanding and involvement in the evaluation process, reasons for and structuring of the initial or diagnostic interview, and development and use of a structured information form. The twenty-one-page Materials Development Center Structured Information Form is provided and its use described. The section on analysis follows a brief discussion with example answers to questions on the information form and evaluation questions (information needs), which were developed from the information. (CE 025 400 provides information on developing individual evaluation plans from these questions.) Tentative steps for using the information in this publication conclude the publication. (YLB)
