Reciprocal peer management: Improving staff instruction in a vocational training program.

Lindsley (1992) paired vocational instructors who had clients with intellectual disability. Each pair took turns watching, graphing, and giving feedback on the other’s teaching.

The study used a multiple-baseline design across six staff. Peers met for five minutes at the end of every day to share graphs and praise correct steps.

Four of the six instructors showed more clear instructions, prompts, and praise. Gains were small and faded for two staff.

The other two teachers barely changed. The authors note the procedure needed tighter rules and more practice.

Lattal (2004) got stronger results by giving one 30-second verbal correction right after each error. Their trainers kept the new skills for weeks. The 1992 peer meetings happened later, so feedback was delayed.

Aznar et al. (2005) also beat the 1992 outcomes. They gave teachers a quick graph every two weeks and saw fidelity double. Adding a supervisor, not just a peer, may explain the jump.

Reid et al. (2005) showed the same point. When clinicians tracked data and coached on the floor, staff prompting rose and stayed high for 14 weeks. Peer-only feedback, like in Lindsley (1992), looks weaker than coach-led feedback.

If you run a vocational or day program, pairing staff for daily check-ins can still help, but don’t stop there. Add real-time cues, supervisor graphs, or brief video clips. The 1992 study is a useful first step, yet later work shows you get more bang when a trained observer joins the loop. Try peer partners plus one quick supervisor feedback round each week.
