Competency-based instructional resources guides were developed for the secondary business educational offerings of legal office procedures, medical office procedures, recordkeeping, and office supervision and management. Task lists for each offering were validated by individuals from business, government, and professional organizations; experienced teachers; and/or content area experts. Initial drafts of the resource guides were prepared from the validated task lists, reviewed by selected business teachers and supervisors, revised, and field tested. To evaluate the guides' effectiveness in assisting teachers to meet Virginia's competency-based educational standards for vocational education, evaluation instruments were administered to teachers and students prior to and after the field testing. Evaluation outcomes indicated that both teachers and students believed courses to be competency-based. (Appendixes, amounting to almost four-fifths of the report, include the task/competency validation lists for all four offerings, validated task/competency lists, preassessment questionnaires, title pages and tables of contents for the four resource guides, field test evaluation instruments, and Virginia Vocational and Adult Education Competency-Based Education Standards: Requirements and Criteria.)
