Communicative competence for people who use augmentative and alternative communication consists of four interrelated domains: linguistic, strategic, social, and operational. Ongoing assessment and progress monitoring within these domains are crucial to (a) providing information to teach targeted skills in a manner contextualized within the curriculum; (b) determining measurable annual Individualized Education Program goals; and, ultimately, (c) ensuring maximal participation in the school environment. Currently, language sample analysis (LSA) is one of only three assessment techniques that provide information across each domain of communicative competence for children who use augmentative and alternative communication (AAC). As such, LSA is a valuable tool for assessing communication competence in children who use AAC in the school setting. This clinical forum describes information that may be obtained from an LSA as it relates to each domain of communicative competence and educational standards.
