An Evaluation of Pyramidal Training to Teach Implementation of the Picture Exchange Communication System

Martocchio et al. (2016) tested a pyramidal train-the-trainer model for PECS. They taught four university students to run phases 1-4 with a confederate learner.

Training followed behavioral skills training: instructions, modeling, rehearsal, and feedback. The researchers then tracked how accurately the students coached new partners.

All four student trainers reached 90-a large share fidelity after one to three coaching rounds. Their trainees also hit high fidelity, showing the pyramid held strong.

Skills lasted one and three weeks later with no extra practice.

The results line up with Ruppel et al. (2023) and Ausenhus et al. (2019). Both used remote BST to reach high fidelity on preference assessments, proving feedback is the key ingredient no matter the skill.

Ganz et al. (2009) extends the story: parents, not just university students, can learn PECS and teach kids to ask for new items. The method travels beyond campus labs.

Guinness et al. (2024) push the model online. Their sequential checklist taught grad students APA citations with minimal live contact, showing pyramidal logic works even through a screen.

You no longer need to train every staff member yourself. Train two or three strong aides using BST, then let them coach the rest. Expect a large share fidelity in a week and durable results without booster sessions. Perfect for clinics, schools, or home programs where time and supervisors are scarce.
