This paper was written for presentation at a symposium of trainers when the author was a trainee in psychoanalytical psychotherapy. The original title was ‘Good Supervision: a consumer's guide’. The author drew not only on her own experience of being supervised but also on that of colleagues in training. It was found that it was essential to conceptualise the experience in terms of the triangular relationship between student, patient, and supervisor. Primitive feelings are evoked by the supervisory process and some of these are described. Characteristics of supervisors and the supervisory process and how these are felt to help, or otherwise, are discussed.
