One welcomed addition to the Behavior Analyst Certification Board Fifth Edition Task List and Supervisor Curriculum (2.0) is the duty of the supervisor to not only teach, but also evaluate “soft skills,” which we will refer to as behavior-analytic professionalism. With this addition, supervisors must teach and evaluate skills related to behavior-analytic professionalism exhibited by their trainees. However, findings from surveys of supervisors in the field indicate two issues:(1) Few view teaching behavior-analytic professionalism as part of their responsibilities under the current supervision guidelines, and (2) they do not know how to teach these skills. Accordingly, we provide supervisors with a recommended training model for teaching skills related to behavior-analytic professionalism, which includes the steps outlined in behavioral skills training. We outline how to get buy in, operationally define the skills, provide multiple examples, and how to ensure trainees have adequate practice so that timely and constructive feedback can be given.
