To develop a procedure for using occupational supply and demand data in state-level vocational education planning, data from an area skill survey, community colleges, technical institutes, and secondary school class records filed in state offices were sorted by occupation and analyzed for completeness, validity, and usefulness for planning purposes. Enrollment data were used to identify occupations not supported by public training programs and those for which enrollment greatly exceeded reported demand. Completion rates for various types of secondary and post-secondary curruculums were compared. Noting that State Board of Education policies emphasize input and ignore output, the study concludes that followup studies are needed, along with other new efforts to measure output. (Author/BH)
