A project assessed current counseling activities, services, and programs in grades 7 and 8 that address vocational interest and aptitude assessment for handicapped and disadvantaged students. Staff developed a description of vocational assessment instruments available to public schools and a guide for interpreting and using vocational assessment data. The description of vocational assessment instruments and the guide were made part of a vocational assessment handbook. Survey data and knowledge acquired in the development of the handbook were used to develop a sample guidance program containing practices needed to comply with Public Law 98-524. Recommendations were made regarding selection of vocational assessment instruments, in-service sessions, and use of vocational assessment information by vocational and special education personnel. (The brief report is followed by these appendixes: (1) a list of project advisory committee members; (2) results of a state-level survey to assess Texas guidance and counseling practices; (3) vocational assessment instrument information on 35 commercial instruments--multiple aptitude tests, interest surveys and inventories, adaptive behavior measures, and combined instruments and work samples--listing title, publisher, population, purpose and description, administration and scoring, scales/scores, norms, reliability and validity, comments, and cost; (4) interpretation and use of assessment data information in the form of the final, complete section as it appears in the handbook; and (5) information on establishing a counseling program designed to fulfill Carl D. Perkins guidelines.) (YLB)
