3. Fundamental Models, Communication Needs, and The Communicative Competence Model
The process of providing intervention with AAC is complex and multi-dimensional. Models have been developed by researchers in the field to help structure the assessment and intervention process. Three fundamental models of AAC exist. The Communicative Competence Model is based on 2nd language learning and also considers the technical skills required to operate AAC systems. Communicating via AAC has its own complications, particularly for children who are still acquiring language.
