This digest focuses on characteristics of good supervisors. Only a few researchers have focused on supervisor qualities and skills, and only three very brief models of supervisor development have been proposed. Good supervisors seem to have many of the same qualities as good teachers and good counselors, i.e., being empathic, genuine, open, and flexible. In terms of professional characteristics, good supervisors are both knowledgeable and competent counselors and supervisors. Existing models of supervisor development are briefly reviewed. The digest concludes with the author's reflections on being a supervisor and a supervisor educator. Contains 8 references. (NB)
