*This is an all too common scenario in special education classrooms and the biggest reason for ensuring that students have been taught Phase II of the Picture Exchange Communication System: Distance & Persistence.

Make sure to create opportunities for your students to travel with their pecs and remember to fade prompts as they begin to master the skill.
