The purpose of this study was to develop a language-based augmentative and alternative communication (AAC) diagnostic classification system (LAAC-D) that can be used in the assessment and intervention phases of AAC for people with complex communication needs in Korea. A comprehensive literature review was conducted focusing on linguistic competence and the four major factors (intentionality, symbolic use, word combination, and grammatical complexity) that play essential roles in classifying communication and expressive language development stages. Seven pieces of literature reported communication levels that are being used for AAC diagnostic system. Among them, only one reflected all factors into the communication level. Most of the literature did not consider the grammatical complexity factor. After examining the characteristics and limitations of each literature, the LAAC-D was developed consolidating the evidence and reflecting the four factors. The characteristics and clinical implications of LAAC-D were discussed.
