The Picture Exchange Communication System (PECS) is a form of augmentative and alternative communication produced by Pyramid Educational Consultants, Inc. Phase 1: How to Communicate During Phase I, the focus is on teaching the student to initiate social communication. 2  The student is taught to approach the communicative partner with a picture of a desired object or food item and place the picture in the trainer's hand, in order to receive the desired reward.
PECS training is not limited by age but rather by a small set of criteria. Thus, PECS training could be offered to a fifty year old adult with a cognitive impairment as well as to a two year old with no cognitive impairment. First of all, the candidate for PECS training should be an intentional communicator. This means that the child (or adult) is aware of the need to communicate his/her message to someone, even if it is in a limited fashion.
