Students seeking certification in supervision and those seeking certification in educational administration were compared in order to examine differences in leadership styles. One hundred forty-nine educational administration students and 121 supervision students participated in the study at the University of Texas at San Antonio. Four self-assessment instruments were used to measure dimensions of leadership style. The data suggested differences in style and organizational orientation between administration and supervision students. Administration students tended to be more task oriented, extroverted, and directive. The recommendations that followed from these findings were: (1) students in supervision and administration should be aware of leadership style models and should be able to assess their own leadership style; (2) techniques that encourage exploration of simulated and real life situations should be incorporated into training programs for supervisors and administrators; (3) training programs should provide for exchange of views among students with different goals in administration and supervision; and (4) ongoing professional development and training programs should be provided for all personnel in administrative and supervisory positions. School districts should also take leadership styles into account when assigning personnel and should make leadership into a team effort whenever possible. Twenty-two references are appended. (GJ)
