Factors influencing the employment tenure of men qualified to teach vocational agriculture were examined to determine the (1) causes of teachers leaving the vocational agriculture teaching profession, (2) relationships between years as a high school vocational agriculture student and tenure in teaching and (3) relationships between employment tenure in teaching vocational agriculture and background variables of the graduate. Questionnaires and permanent college records were obtained for 1,022 recipients of B.S. degrees in Agricultural Education from 1940 to 1964. Their home background, high school and college record, first employment, and employment in 1964, were among the data collected. Throughout the 25-year period, 32.6 percent of the graduates who had entered teaching were teaching vocational agriculture in 1964. Graduates who had entered vocational agriculture teaching but left for other occupations ranked the following items as having had the greatest influence on their decision: (1) (1) long hours and evening responsibilities, (2) salary and advancement opportunities, (3) community factors, and (4) failure to adjust to the teaching assignments.
