To improve vocational educational programs in agriculture, occupational information on a common core of basic skills within the occupational area of the grain farmer is presented in the revised task inventory survey. The purpose of the occupational survey was to identify a common core of basic skills which are performed and are essential for success in the occupation. Objectives were accomplished by constructing an initial task inventory to identify duty areas and task statements for the occupation. The initial task inventory was reviewed by consultants in the field, and 248 tasks were identified. A random sample of 75 grain farmers based on the 1974-75 Ohio Young Farmers Association, Inc. was obtained. Data were collected utilizing a questionnaire. Thirty-eight questionnaires were returned of which 32 were usable. A compilation of basic sample background information is presented on the size and type of grain farm, years as a grain farmer, and preparation as a grain farmer. A compilation of duty areas of work performed and work essential for the occupation is given. Percentage performance by incumbent workers and the average level of importance of specific task statements are presented in tabular form. (Author/EC)
