The objective of the study was to develop a dynamic system for inputing data on human and occupational resources for use in developing vocational education programs to meet current and future occupational needs. In the first of four phases, the objectives were to develop: (1) data gathering instruments designed to continuously assess human resources, employment opportunities and educational programs; (2) a system for assessing job opportunities which cluster required job skills and mental processes; and, (3) manuals of procedure for use by field personnel in administering data gathering instruments and employing the clustering system. Survey questionnaires to be used with students, dropouts, employees, employers, secondary school vocational programs, community college vocational programs, and proprietary schools were developed, field tested, analyzed, and modified. A two-dimensional clustering system which combined worker functions and processes was developed, jobs in occupational areas representing mechanical, electrical, and symbolic skills were used as samples in developing task descriptions and numerical loadings from which clusters were formed. Guidelines were prepared for administering data gathering instruments and employing the clustering system. Included are: (1) detailed descriptions of instrument development, (2) a bibliography, and (3) extensive appendixes containing related information, an instrument analysis, the guide for administering instruments, the instruments, a supplement to instrument utilization, task descriptions, and classification loadings.
