Learning to obtain, evaluate, and synthesize information ahout clients (i.e., case conceptualization) are essential competencies for therapists. We have presented a theory-driven and flexible clinical supervision method (Chalkboard Case Conceptualization, CCC) for teaching supervisees to synthesize clinical data into an integrative understanding of the client, assimilate clinical theory and empirical findings into clinical practice, and foster supervisees' cognitive reasoning in a clinical context. A client example is used to illustrate the CCC process and implementation. Adaptations of CCC for individual, group, and family therapy, and for training supervisors to conceptualize their supervisees are offered. Strengths and limitations are discussed along with suggestions for future research on the CCC method.
