Augmentative and Alternative Communication (AAC) are tools, technologies, and approaches used to provide ways other than speech to aid communication-related challenges (American Speech-Language-Hearing Association, n.d.). A communication board is a low-tech AAC tool seen in various formats such as printed on a poster board or digital applications on electronic devices. It consists of rows and columns of squares with simple pictures and minimally-worded labels in the preferred language.
