Introduction Agriculture is America's largest and most basic industry. Of the more than 100 million people in the U.S. labor force, about 22 million are employed in more than 200 agriculture-related occupations. Of those 22 million, less than 2 percent are engaged directly in production agriculture. In the Midwest, an even greater share of the work force, 34 percent, is employed in agriculture. Therefore, agriculture education is justifiably a part of Wisconsin's educational efforts at all levels, from kindergarten through postsecondary education. The Wisconsin Department of Public Instruction demonstrates its support for a comprehensive K-12 initiative in its publication, "A Guide to Curriculum Planning in Agriculture Education". "Instruction for Food and Fiber and Natural Resources" fine tunes this initiative even further by focus ing on curriculum development in agriculture education programs for middle/junior high and high schools. This publication provides more than 80 instructional units for agriculture education based on the following seven employment clusters, which are described in the DPI's curriculum guide: - Agriculture Science/Production Management - Agriculture Processing/Food and Fiber - Agriculture Marketing/Distribution and Retailing Services - Agriculture Supplies and Services - Agriculture Mechanization/Engineering and Technical Support Services - Agriculture Resources Management - Professional Employment in Agriculture In addition, "Instruction for Food and Fiber and Natural Resources" offers several instructional units under a "Cross-Cluster" category; these units are applicable to two or more of the employment clusters.
