The purpose of the study was to determine the effectiveness of Mississippi preservice vocational programs in developing the performance levels of vocational teachers. Questionnaires were mailed to all Mississippi vocational teachers with one to three years of teaching experience, State level supervisors, and teacher educators; 405 questionnaires were included in the study. A rating scale was utilized that consisted of five levels ranging from inadequate performance to competent performance; 94 performance tasks were assessed in areas of: planning of instruction, execution of instruction, evaluation of instruction, guidance, management, public/human relations, professional role, student vocational organizations, and program coordination. Only one group, program coordination, was assessed at below the adequate level. Some specific recommendations derived from the study were the need for increased preservice experience in: "actual" school situations, team teaching approach, standardized testing, guidance related tasks, budget planning, preparing reports, student disciplinary actions, use of media, research studies, working with youth organizations, and program coordination. More than half of the document consists of appendixes of supportive data. (EA)
