A project was designed to develop a system that would prepare adult vocational instructors to design, develop, and implement competency-based programs for their students. Additional objectives included identifying occupational competencies, developing and field testing vocational materials, and evaluating participating instructors' teaching competencies. The project utilized a competency-based staff development program for adult educators developed in 1975-76 at the University of Maine. The teacher-instructor competencies developed by the Center for Vocational Education at Ohio State University were selected as a basis for the program. Twenty adult vocational instructors from the Northern Maine Vocational Planning District were selected to participate. Individualized plans developed for each participant provided a basis for completion of the competencies in the various subjects represented. Among project outcomes were the following: the major objective was achieved; teachers were receptive to competence as a basis for professional evaluation and responded positively to individualized self-directed study; and though the project did not achieve its goal of developing finished modules (twelve are currently being revised and edited) for state distribution, vocational instructors in Aroostook County (Maine) became a focus for improvement in teaching.
