“…Supervisors must teach and evaluate professionalism related to (1) time management (e.g., measure planned activities vs. actual activities, adherence to deadlines, attendance), ( 2) organization (e.g., measure client programming, meeting preparation), (3) prioritization (e.g., measure appropriate allocation of time toward tasks based on criticality), (4) social skills (e.g., evaluate posture, adaption to audience, select appropriate attire), and (5) interpersonal skills (e.g., social interactions, flexibility). Encouragingly, Sellers, et al (2019) recently found that supervision-providing BCBAs and BCBA-Ds (n ϭ 284) directly measured their trainees' interpersonal and communication skills (67.3%), time management (68.7%), organizational skills (67.7%), and prioritization skills (63.7%). Discordantly, the same group of supervisors who reported measuring soft skills also indicated that they felt they did not know how to measure or teach time management, organization, and interpersonal communication skills.…”
