This research brief, developed by the Advancing ALTELLA: Alternate Assessment Redesign project housed within the Wisconsin Center for Education Research, explores the use of augmentative and alternative communication (AAC) devices for English learners (ELs) with significant cognitive disabilities. With the increased use of technology in teaching and learning, this resource gives an overview of what AAC devices are and how they support the communication practices of ELs with disabilities. The brief calls for educators and families to have a clear understanding of how AAC devices work, how to program them, and how to support students in utilizing them to communicate. More specifically, the brief considers the need to program the devices multilingually to support the language development of English learners. Lastly, the brief closes with questions that ask educators to consider identifying and working with AAC devices.
