Since a competency-based approach to training supervisors and administrators of vocational education programs appears to be one solution to the problem of inadequate personnel programs, a study was conducted to identify professional competencies required of supervisors and administrators in successfully fulfilling their leadership roles. The study also sought to discover if there are different competencies required for each group. An eighty-four-item descriptive survey instrument was distributed to 282 supervisors and administrators in the state of Florida. Respondents were asked to rate each listed competency on a six-point scale as to its importance. Based on a fifty-two percent return, a one-way analysis of variance was applied to determine if significant differences existed between the mean importance ratings of competencies among groups of administrators and supervisors. A t-test was also used to determine significant differences in perception of the importance of competencies between supervisors and administrators. The study concluded that the responsibilities of vocational education supervisors and administrators are varied and that competencies important to them do not vary greatly. The study also concluded that the competencies required for supervisors and administrators are somewhat similar. (Author/JH)
