The competencies needed by Iowa vocational agriculture instructors at the secondary school level to integrate computer technology into the classroom were assessed, as well as the status of computer usage, types of computer use and software utilities and hardware used, and the sources of computer training obtained by instructors. Surveys were mailed to 119 vocational agriculture instructors who had completed a university-sponsored workshop in the use of the personal computer. The survey asked respondents to describe their vocational program and status of computer usage within that program, and to rate the importance of 50 specific computer competencies. Based on 115 usable surveys, findings indicated that the most important instructor competencies were those required for using computer hardware and software in the classroom, rather than computer programming. Such factors as years of teaching experience, student enrollment in vocational agriculture, student enrollment in high school, and number of personal computers available for class use were not strongly related to the teachers' ratings of the four competency areas (hardware, instruction, programming, and software). Fourteen references are listed, and ten tables display study data. (LMM)
