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 covered by the Matrix would occur between 0 and 24 months of age. The Matrix accommodates any type of communicative behavior, including "augmentative and alternative" (AAC) forms of communication and pre-symbolic communication. It is appropriate for individuals who experience any type or degree of disability, including severe and multiple disabilities. 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 levels of communication.
