Alternative and augmentative communication (AAC) is an umbrella term for the many ways we communicate outside of verbal communication. This includes several different means of communication including gestural communication and manual signs as well as low-tech and high-tech AAC (ASHA, n.d.). The AAC assessment process for children varies from one individual to another due to the clinical heterogeneity of pediatric AAC users. It’s estimated that approximately five million Americans and almost 100 million people in the world could benefit from AAC (Beukelman & Light, 2020). Individuals who use AAC vary depending on their medical diagnosis, age, speech and language development, fine and motor abilities, and their prognosis.
