The School Based Teacher Educators Project (SBTE) had as one of its major goals the development of a set of competency specifications for the role of school based teacher educators. This paper describes the process that was used to identify the competencies. A number of different approaches have been advocated by various educators for identifying the competencies required for a given role--all of these approaches include some type of role or task analysis, review of research related to role functions, and an analysis of literature advocating new functions for the roles. The competencies presented in this paper were identified through the following process: (1) a comprehensive review of the literature related to inservice and preservice education which provided the basic information on the functions and tasks of the school based teacher educator's role; (2) interviews conducted with 19 supervisory personnel representing five school districts provided practicing professional's perceptions of the school based teacher educator role; (3) an initial list of competency statements was drawn, and to further analyze and validate the list, an external expert review was organized and conducted; (4) competency statements were again reviewed and revised several times. This paper concludes with a list of 20 competency statements along with the remark that at the time of the paper's writing more specific competency statements were still being developed. (MM)
