One of the greatest challenges of being a supervisor in behavior analysis is establishing measurement and evaluation strategies to determine the competency of those you are supervising. While the BACB task list/test content outline provides a general idea of what to measure, much of the development process is left up to the supervisors themselves. This lesson will focus on how to use the Task List and job models to establish measurement tools, including checklists, behaviorally-anchored rating scales, and countless fundamental measures of supervisee/trainee performance. Formal and informal monitoring will also be discussed, including how to reduce reactivity and increase acceptability of supervisees and trainees towards evaluation processes. Finally, strategies for evaluating the effectiveness of the supervision program itself will be shared, providing ideas for new and experiences supervisors alike to enhance their processes related to supervising others.
