The PSI Apprentice Training is structured as an apprenticeship rather than a lecture-based course. The program emphasizes learning psychedelic psychotherapy from the inside out through direct experience, observation, and personal integration. Part A is a 5-day in-person experiential component with small cohorts, live sessions, observation, and integration work. Part B consists of live online theory lectures. Part C provides live online supervised practice sessions and supervisions focused on applying PSIP with peers or practice clients. The training is designed for mental health and medical health professionals with at least two years of clinical experience, as well as experienced healing arts practitioners who work with clients in a mental health context. An optional Part D allows additional observation for further skill development.
