What is the role of the trainer in Phase 1 of PECS?

In Phase 1 of the Picture Exchange Communication System (PECS), the primary role of the trainer is to facilitate the exchange of a picture by the learner to communicate a desire or need. This initial phase is focused on teaching the student to understand that they can use a picture to obtain a desired item or action. Thus, the trainer takes on the responsibility of receiving the picture from the student, which reinforces the concept that communication can occur through nonverbal means.

The emphasis is on establishing a clear connection between the picture and the item or activity it represents, creating a functional communication experience. As the student hands over the picture, they are rewarded with access to the desired item, making this interaction a vital part of their learning process. This foundational step is critical for progressing to more complex phases of the PECS where the ability to construct sentences and engage in more elaborate forms of communication will develop.
