The process through which individual psychodynamic practitioners learn how to learn from practice is central to their future professional development and second only to having had a ‘good enough’ experience of personal therapy. To facilitate this learning process many trainees, particularly those working within organizations, might be offered the opportunity to join a supervision group. The aim of this article is to explore some group dynamic issues that might enable greater understanding of this learning opportunity. Literature from the general field of professional education will be integrated with more specific psychodynamic and group-analytic psychotherapy sources. Implications for the place of analytically informed cooperative inquiry groups in continuing professional development will also be briefly discussed.
