Abstract The authors conducted a comparative study of the supervision of student teachers and student counselors and their development. The authors were interested in whether student practicum progress and practicum supervisory strategies are consistent with a developmental model. Findings for the progress of student counselors were consistent with a developmental model; those for student teachers were not. Supervision strategies for the supervision of both student counselors and student teachers were consistent with a developmental model. The authors suggest inservice training in supervision for cooperating teachers and additional research to validate inservice training strategies.
