To encourage vocational evaluation professionals to think about the importance of providing clients with occupational facts and informaton, rationale and guidelines are presented for incorporating more occupational information into the vocational evaluation process. Following a section defining occupational information and related terms, the need for occupational information is argued on the premise that performance on work oriented evaluation procedures (i.e., work samples, situational assessment, etc.) simply does not provide all the facts and information the client needs to have a good overall picture of the unique characteristics of different jobs such as wages, working conditions, educational requirements, etc. Succeeding sections suggest some ways of using occupational information in vocational evaluation, ways of classifying the information for the most convenient client and professional use, and how to find out and keep up-to-date on what occupational information media exists. Suggested initial materials for purchase for a starter occupational information resource area are listed along with ways to determine what occupational information should be ordered to meet the needs of the particular facility and clientele.
