The Communication Matrix helps speech-language pathologists and educators document early-developing expressive communication modes in children with complex communication needs. This tool organizes expressive communication into seven levels (from pre-intentional behavior to conventional language use), and across four main reasons to communicate: refusing, obtaining, social interaction and seeking information. The Communication Matrix was published by Dr. Charity Rowland in 1990, and updated in 1996 and 2004. Professionals can order print copies from http://www.designtolearn.com. There is also a free online tool designed to be filled out with parents; this version has specific questions to guide parents and familiar partners as they describe the child’s expressive communication.
