Training in supervision, familiarity with the supervisory literature, and experiences as supervisors were surveyed in 62 supervisors at clinical psychology internships. Supervisors had received or obtained relatively little training in supervision, had read relatively little about supervision, and had limited supervisory experience. Supervisors' appraisals of both their own supervisory and evaluation skills and the skills of other supervisors are presented. Estimates about the incidence of various problems within supervision, including distress and impairment in interns, are also provided.The authors discuss a range of concerns regarding the establishment of standards for more extensive training in supervision for psychologists, including ethical issues, the need for additional and more substantive research in supervision, and the potential expansion of supervisors' roles. The development of guidelines for training and supervising supervisors is recommended. [Article copies available for a fee from The Haworth Document Delivery Service: 1-800-342-9678.
