The Communication Matrix is a free assessment tool with robust scientific and clinical roots that helps those who support people with severe communication difficulties find a path to self-expression. It pinpoints an individual’s current communication level and gives a framework for determining future goals.

The Matrix includes all types of communication, including alternative forms (picture systems, electronic devices, voice-output systems, Braille, sign language and 3D symbols) and pre-symbolic communication (gestures, body movement, sounds, eye gaze and facial expressions), as well as typical communication (speech). It covers seven levels of development in the earliest stages of communication.
