The use of sandtray in group supervision is a novel approach to supporting counseling supervisees' professional growth and development. We piloted a ten-week supervision group protocol utilizing sandtray for graduate-level counselors-in-training during their fieldwork experience in an in/outpatient behavioral health hospital. This article provides a brief overview of the use of sandtray in supervision, a detailed description of the ten-week protocol, and unique student perspectives by including excerpts from weekly journal reflections. Additionally, we offer implications for protocol implementation, considerations for clinical supervisors, and suggestions for future research.
