The ABA Supervision Handbook is the first of it's kind: a structured, repeated measures assessment of behavior analytic skills that each behavior analyst should have in their repertoires. This manual/protocol serves as a standardized supervision tool for supervisors to use to guide their supervisory practices. With each each section of this tool, the supervisor can work closely with the supervisee to assess, monitor, and train skills across assessment, measurement, personnel management, professionalism, and ethics, among others.
