Developed by means of a research project, this teaching guide includes five instructional modules in which competencies for agribusiness occupations are stressed. These competencies were identified from a review of the literature and evaluated by a jury of teachers and agribusinessmen in terms of qualifications needed for entry-level employment. Using a Likert-type rating scale, competencies were identified for the following areas of modules: (1) Human Relations in Agribusiness, (2) Communications in Agribusiness, (3) Agricultural Salesmanship, (4) Agricultural Sales Promotion, and (5) Agribusiness Operations. The five modules are further divided into 40 instructional areas which include a list of competencies to be developed, recommended references, supplementary references, and suggested learning activities. The final report of the research efforts, which identified the needed competencies for a secondary education program in agribusiness, is included in this document. (JS)
