Counselor educators and supervisors are familiar with the use of competencies for training future clinicians but the extant literature lacks a set of competencies for use in training future counselor supervisors. The purpose of this study was to develop and validate a list of supervision competencies experts agree should be demonstrated by new doctoral counseling graduates for their work with master's students, pre-licensed or licensed counselors, and doctoral students. The research design included two expert panels, an amended Delphi poll, and a content validity assessment. These procedures resulted in a consensus list of 33 supervision competencies that appear to be a valid representation of supervision competencies expected of counseling doctoral graduates.
