A study was conducted to determine the following: the characteristics of state-level administrative structure for vocational education within state departments of education; the current role and the expected role of state supervisors of vocational agriculture as perceived by high school teachers and state supervisors of vocational agriculture, and the relationship between state-level administrative structure for vocational education and current and expected roles of state supervisors of vocational agriculture. A two-phase study was conducted by sending questionnaires to (1) 50 head state supervisors of vocational agriculture and (2) a random sample of 504 high school teachers of vocational agriculture in 19 states (80 percent response), and all 196 state supervisors of vocational agriculture (92 percent response). Data collected resulted in the classification of state-level administrative structure of vocational agriculture into four categories depending on degree of authority of the state supervisors. State supervisors and teachers had similar perceptions of the current role of state supervisors of vocational agriculture; they were also similar in their perception of the expected degree of authority of state supervisors at the same level as current degree of authority. Recommendations were made for further research into the actual activities performed by state supervisors and the degree and nature of contact between state supervisors and local teachers of vocational agriculture.
