The authors present a model for teaching group at the master's level that integrates classroom with experiential group practice. The basis for this adult learning model is an understanding of addiction, a model of how people change, and an appreciation of the stages of group development. The components of the model are didactic presentation, class discussion, small and large group process, a clinical laboratory and faculty clinical supervision. A performance scale, the Group Leadership Effectiveness Scale, is utilized to evaluate student progress and complete this model.
