The effect of feedback on the accuracy of checklist completion during instrument flight training.

Lambrechts et al. (2009) taught flight students to fill out safety checklists without errors.

After each simulator flight the instructor showed them a simple bar graph of their checklist hits and misses. He added quick verbal tips and praise for any gain.

The study used a multiple-baseline design across three trainee pilots.

Once the graphic plus verbal feedback started, checklist scores shot to nearly 100% for every pilot.

The high scores stayed even after the instructor stopped giving the feedback sessions.

Aznar et al. (2005) got the same jump in fidelity with teachers using behavior support plans. They used bi-weekly feedback instead of post-flight, but the pattern matches: brief, timed feedback plus praise equals skill that sticks.

Lattal (2004) also lifted trainer accuracy with immediate verbal feedback alone. G et al. show that adding a simple graphic gives the same lift, so you can pick either tool or pair them.

Vance et al. (2025) later moved the graphic-only idea to preschool staff and cut stationary behavior. This extends the same visual feedback trick from cockpit to classroom.

If you train staff on any step-by-step protocol, borrow this package: one graph, one sentence of praise, one quick tip. It takes two minutes after the session and pushes performance to the ceiling. Try it with RBT skill checklists, parent training data sheets, or clinic opening routines. The pilots kept the skill with zero extra work, so your team can too.
