Abstract
Communication is a basic human right, as affirmed by the National Joint Committee for the Communication Needs of Persons with Severe Disabilities (NJC, 2024). For individuals with complex communication needs (CCN), special considerations must be taken into account to ensure equitable access to this right and must be supported through appropriate services, tools, and strategies. Augmentative and alternative communication (AAC) systems are essential for many individuals with CCN, enabling access to expressive and receptive language. However, successful AAC implementation requires well-trained educators, speech-language pathologists, and support staff who understand how to assess, model, and support communication effectively (Brady et al., 2016).
This paper examines the importance of professional development for those working with individuals with CCN, emphasizing evidence-based strategies like aided language modeling (ALM) and using core vocabulary instruction. ALM, which involves consistently modeling communication with AAC systems during natural communication opportunities, has been linked to gains in both receptive and expressive language (Biggs, Carter, & Gilson, 2018). Core vocabulary instruction, which emphasizes teaching high-frequency and versatile words, supports expressive and functional communication across settings and has been shown to promote grammatical development and message generation (Binger & Light, 2008; Beukelman & Light, 2020). The integration of these strategies—ALM and core vocabulary—into AAC instruction has been shown to improve communication outcomes for nonspeaking learners.
Furthermore, this paper underscores the importance of interprofessional collaborative practice in AAC service delivery. Collaborative models that unite the expertise of educators, speech-language pathologists, and other specialists are vital for developing individualized, meaningful, and sustainable communication interventions (Bruce & Bashinski, 2017). With clear, evidence-based training and collaborative support systems, professionals can uphold the communication rights of individuals with CCN and significantly enhance their quality of life.
