There is now a sizeable literature on supervision, some of it very good. There are courses in supervision, qualifications in supervision, accreditation in supervision. Instead of being something one got landed with at a senior stage in one’s development as a therapist, it has become a speciality within the whole field of psychotherapy and counselling. The point has been made many times in this book that if we take seriously the idea that there is such a thing as psychospiritual development, then therapy can be adapted to various stages within that. But this way of thinking has never, to the best of my knowledge, been applied to supervision. This chapter attempts to fill the gap.
