Strategies are offered for implementing such an approach to competency-based clinical supervision, as well as for overcoming barriers to implementation.After reading and discussing as a group a series of pertinent articles, Dr. Collégial and her training committee invite a nationally recognized expert in competency-based supervision to provide a workshop to the training program (faculty, staff, trainees, and administrators). Following a working lunch with the expert, the audience breaks up into workgroups to discuss ways the model could be implemented at their site. This is followed by a retreat 1 month later, in which the training committee creates a step-by-step plan for shifting the culture from one that supported multi-faceted
