Abstract
Supervisor/supervisee co-leadership teams are common in practice yet neglected in the literature. The issues particular to this training arrangement are addressed from within the context of systems theory. The supervisor/supervisee dyad represents the intersection between the therapeutic and training systems. Each of the members of these systems are addressed in turn-supervisor, supervisee, the dyad working together, and the group itself. Based on the premise that each element affects all of the others, it is posited that, when considering both training and therapeutic efficacy, the supervisory co-leadership team provides advantages over other training arrangements.
