PECS (Picture Exchange Communication System):

PECS consists of six phases and begins by teaching an individual to give a single picture of a desired item or action to a ‘communicative partner’ who immediately honours the exchange as a request. The system goes on to teach discrimination of pictures and how to put them together in sentences. In the more advanced phases, individuals are taught to use modifiers, answer questions and comment. Many young people use PECS and build upon this knowledge to become more verbal in their communication.
