The Communication Matrix is appropriate for individuals of all ages who are at the earliest stages of communication. In the typically developing child the range of communication skills that the Matrix covers would occur between 0 and 24 months of age. The Matrix accommodates any type of communicative behavior, including “augmentative and alternative” forms of communication (AAC) and pre-symbolic communication (such as gestures, facial expressions, eye gaze and body movements). It is appropriate for individuals who experience any type or degree of disability, including severe and multiple disabilities, intellectual limitations and sensory or physical impairments. The Communication Matrix is NOT suitable for individuals who already use some form of language meaningfully and fluently. Throughout the Matrix material, the person being assessed is referred to as "your child". Please note that the Matrix is equally applicable to adults who are functioning at the earliest stages of communication.
People all over the world use the online Communication Matrix. At this writing, about 38% of users are speech-language pathologists, about 26% are educators, and about 13% are family members. One of our goals is to encourage professionals and parents to complete a Matrix on the same child so that they can compare and discuss the similarities and differences that they see at home and at school.
