The report provides essential information for curriculum development relevant to manpower demands for agricultural production and agribusiness in Montana. It focuses on an analysis of 3,500 competency statements to determine the existence of duplication, commonalities, and uniqueness among 76 identified job titles derived from six Agricultural Manpower Project Competency Studies. The study was conducted by developing a manipulative method for handling the competency statements, establishment of common cores and sub-cores, a review and revision of competency groupings, and documentation of the taxonomy. The eight subject matter cores include animal science, plant science, mechanics, clerical, leadership, business management and marketing, merchandising, and miscellaneous. The data are analyzed in two sets of tables: the first series of six tables documents the unique competencies appearing for the job titles covered in the six studies, and the second series of eight tables documents the competencies according to the eight major cores and corresponding sub-cores to relate commonalities. Conclusions and recommendations based on the data are presented. A bibliography is included. Competency numbers and related job titles listed by study are appended. (Author/EC)
