The Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE) requires that accredited programs evaluate trainees' clinical skills at various times during trainees' programs. The Commission does not attempt, however, to describe for programs eigher the nature of the skills nor how they are to be evaluated, leaving this to the programs to create. This paper describes the development and uses of the Basic Skills Evaluation Device (BSED). Using a published list of skills (Figley & Nelson, 1989), data from the literature, and data collected from COAMFTE accredited and candidacy programs, the authors and their colleagues developed a device for supervisors to use in evaluating beginning family therapists. Data regarding the reliability of the device presented, along with limitations and suggestions for various ways of using the device.
