Language is the common thread underlying speaking, listening, reading, and writing. For children who use augmentative and alternative communication (AAC), a solid foundation in language and communication is essential to active literacy learning across grades. This article examines the language and literacy relationship for children who use AAC. It describes the language and literacy development of these children, highlights intrinsic and extrinsic learning challenges, examines the communication-based literacy learning experiences of these children, and addresses the important role of language and communication in the literacy curricula of classroom settings. Ideas for fostering AAC, language, and literacy connections are presented.
