Survey of AAC knowledge of practitioners in special schools in Tianjin area in China

Augmentative and alternative communication (AAC) systems support individuals with significant communication challenges. In mainland China, AAC implementation remains limited, particularly within school settings due to a shortage of certified speech-language pathologists (SLPs). This study surveyed AAC-related knowledge, practices, and training needs among special education personnel in Tianjin, China, where educators often serve as de facto AAC providers. A 10-item questionnaire was administered to 383 teaching and non-teaching staff across ten special schools (response rate: 64.6%). The survey explored self-reported AAC competence, populations served, preferred training formats, and reading materials. Respondents reported limited knowledge of AAC, especially in low- and high-tech modalities. Most participants expressed a strong desire for training, favoring mentorship and workshops. Those with experience supporting students with autism, intellectual disabilities, and cerebral palsy showed stronger preferences for evidence-based materials and structured training. Principal component analysis (PCA) revealed a uniformly high interest across training topics, indicating broad foundational needs. Findings highlight the urgent need for accessible, entry-level AAC training tailored to the educational context in China. Results can inform national policy, curriculum development, and cross-sector collaboration to build sustainable AAC capacity.
