Abstract
The aim of this article is to offer to transactional analysts a simple theoretical and practical tool to support relational supervision. The authors propose the comparative script system as a useful aid to the training of supervisors, with particular reference to three areas: a framework for focusing on the key issues in supervision; a practical instrument for understanding and visually representing transference-countertransference dynamics; and a clarification of the boundary between supervision and therapy. While the focus is on its use in psychotherapy, the model can be used in all fields.
