Abstract
One of the greatest challenges facing augmentative and alternative communication (AAC) professionals is providing children with complex communication needs with access to the vocabulary that they need in order to develop mature language and literacy abilities. The purpose of this study was to analyze the vocabulary used by typically developing early-elementary children in the United States and New Zealand when they write about self-selected topics, in order to inform practices with children with complex communication needs. The children's writing samples were compared across school ages and countries. The school age comparisons highlighted the relatively restricted range of vocabulary used by children in the earliest stages of writing development, and the country comparisons revealed differences in core vocabulary. The findings of this study hopefully will assist AAC professionals as they engage in selecting, prioritizing, and organizing vocabulary to support written language development in children with complex communication needs.
