A five-phased project is described which was designed to develop more specific diagnostic procedures and instrumentation that would allow both the vocational counselor and the prospective student to determine more effectively specific occupational programs and occupational objectives for education at the postsecondary level. Phases of the project related to the specific project objectives, which are outlined: (1) To develop a methodology for the student to experience the nature of instruction and the environment in a selected occupational area prior to enrollment in a specific occupational training program; (2) to apply the methodology to six occupational areas (drafting, welding, automotive service, secretarial, machine shop, and practical nursing) by development of specific tasks and environmental conditions inherent in the occupation selected by the student; (3) to research and select instruments adequate to discover prospective student interest for an occupation; and (4) to apply the methodology developed under test or experimental conditions to a sample of prospective students applying for admission. Conclusions note the advantages of allowing students the opportunity to sample specific experiences and job related instruction and the advantages of using a variety of methods in student selection of an occupation and in an institution's admission process. Information on project evaluation, findings, and recommendations is included. (SH)
