Doctoral students in a Council for Accreditation of Counseling and Related Educational Programs (CACREP) accredited program are required to have training in clinical supervision. Frequently doctoral counseling programs have a supervision practicum course designed to facilitate student development into a supervisor. This qualitative research utilized a collective case study approach to gather descriptions of the experiences doctoral students found most useful about their supervision training. Doctoral students enrolled in a supervision practicum course were asked to describe their experiences as supervisors in training through a semi-structured interview approach. Three broad themes emerged from the data: Facilitation of Development, Formation of Supervisory Style, and Supervisory Roles. Descriptions of the themes and specific experiences doctoral students identified as contributing to their development are explored
