We all communicate for a variety of reasons. Sometimes we want to get something or relay information or even share an experience. Individuals with ASD also communicate for a variety of reasons. It is important to understand the functions of communication so that we can teach students with ASD to communicate for different reasons so they can also have their wants and needs met and be more independent.

Now that we've met Nathan, let's look further at the functions of communication before we decide how to support him. Often, individuals with ASD will begin with requesting as their primary reason for communicating. As we work with individuals with ASD, it is important to remember that we need to consider why a student would want to communicate and teach the different functions of communication.

Below you will see a table that includes different functions along with a brief description and examples.
