Communication Matrix

The Communication Matrix is a fantastic tool created to assess early communicators and guide intervention development.

The Communication Matrix is a tool that I have used to help me better assess my student’s strengths. Knowing their current level of communication allows for more appropriate programming!

The communication matrix breaks down early communication into the following five levels:

1. Preintentional Behavior (0-3 months) – In this stage, we see behaviors, but they are not under the child’s control. Because they reflect the general state or feelings of the child. For Instance; We might see an infant cry due to hunger or the need for a diaper change. Typically the caregiver interprets the behaviors of a child to determine their needs.

2. Intentional Behavior (3-8 months) – Children control behaviors, like body movements, eye gaze, and vocalizations. They are not communicating intentionally yet.

 Intentional Communication Starts

3. Unconventional Communication (6-12 months) – In this stage, children are using “unconventional pre-symbolic” behaviors to communicate intentionally. The behaviors are unconventional as they would not be appropriate for an older child. The behaviors are not symbolic; they do not have a specific meaning. Children may cry or vocalize for the desired item or to be held.

4. Conventional Communication (12-18 months) – The pre-symbolic behaviors are used purposefully and are socially acceptable. Further stages may maintain these behaviors. For example; hugging, pointing, waving, joint attention sharing, and gesturing.

Symbolic Communication Starts

5. Concrete Symbols (12-24 months) communication using concrete symbols is common. Concrete symbols look or feel like the item they represent—for example, a cup representing a drink or a shoe picture to represent a shoe. While most children skip this stage and use abstract symbols, we may work or have children who communicate with concrete symbols.

6. Abstract symbols (12-24 months) – Vocalizations (speech), sign language, written words, and braille are all examples of abstract symbols. These symbols do not match the object or the idea they represent.

7. Language (24 months)
