A project revalidated, revised, and adapted/modified the minimum core competencies for the management and cooperative vocational/industrial education (CIE) courses on the secondary level. In Missouri, each marketing instructor teaching a management course and each CIE instructor completed a survey instrument for the assessment of each core competency in the current curricula. Data were tabulated and reviewed by project advisory committees, and revisions and/or modifications were made. A review was then conducted by selected business/industry personnel for each curricula. Focus groups reviewed the revised core curricula and solicited information concerning instructional resources. The revised core competencies were cross-referenced with selected textbooks and resource materials. The project resulted in the development of revised core competencies for the management course in the marketing education curriculum and general related competencies for the CIE curriculum. (Appendixes to the report are survey instruments and the revised competency listing for management and CIE. For each area, a teacher's resource guide details the cross-referencing of competencies to instructional materials. Each resource guide is structured as follows: review of revalidation process; list of revisions in the core curriculum; core curriculum; expected student learning outcomes; suggested curriculum model, including week number, primary focus/core competencies, and secondary focus/occupational specific; and cross-referenced instructional materials.)
