A national study (the seventeenth annual study of its kind) examined the supply and demand for teachers of vocational agriculture in 1981. To obtain data pertaining to supply and demand for vocational agriculture teachers, researchers mailed questionnaires and follow-up letters and made telephone calls to all institutions preparing teachers in vocational agriculture as well as to the offices of state supervisors in agriculture. Information regarding numbers of graduates qualified to teach agriculture and the number of teaching positions available were then tabulated for each state and each institution preparing teachers. Data revealed that while the secondary vocational agriculture supply and demand situation has stabilized in recent years, a shortage of vocational agriculture teachers continues to exist. While fewer secondary teachers are teaching production agriculture and more are teaching ornamental horticulture, the number of postsecondary teachers is balanced among production agriculture, ornamental horticulture, and other specialty areas. Most secondary positions were filled by fully certified teachers. Recommendations called for increased efforts to recruit students into vocational agriculture education, to reduce teacher turnover, and to broaden certification standards. (MN)
