Maintaining proficient supervisor performance with direct support personnel: an analysis of two management approaches.

Horner-Johnson et al. (2002) compared two ways to keep supervisors sharp. One group got direct feedback right after they watched staff. The other group got the same notes later, in a packet.

The team flipped the two styles across days so each supervisor tasted both. They tracked how well supervisors spotted staff errors and gave helpful coaching.

Direct, on-the-spot feedback kept supervisor scores high every day. When the same notes arrived late, scores slipped.

The lesson: timing beats paper. A quick "Here’s what I saw" keeps skills alive better than a tidy folder handed out later.

Preston (1994) ran a similar drill with school principals. They also found that live feedback, goal setting, and praise kept leaders active and boosted student scores. The pattern repeats: right-now feedback works at every level.

Paden et al. (2025) push the idea further. They let staff watch short clips of their own work and score themselves. Self-checking kept fidelity high even when no supervisor was in the room. W et al. showed supervisors need live input; Paden shows staff can learn to give it to themselves.

Bowe et al. (2018) line up closely. They used BST to fix paraprofessionals’ DTT error-correction mistakes. Like W et al., they saw that hands-on practice and feedback beat passive reminders. Together the studies say BST keeps staff accurate across tasks—whether you’re watching staff or teaching kids.

If you train supervisors, stop saving feedback for the weekly meeting. Catch them right after an observation and tell them what you saw. One minute on the floor beats a five-page memo later. Start tomorrow: follow one supervisor, share one quick win, and watch their next staff interaction improve.
