Counselor education programs depend on site supervisors to mentor and monitor the work of practicum and internship students. This presentation will discuss a developmental model for orienting, training, and providing ongoing support to school counseling site supervisors in order to address CACREP Standards III.C.3-4 and III.D. Information will also be shared on an accountability system used to assess supervisor needs, evaluate the effectiveness of trainings, and monitor the performance of site supervisors.
