A qualitative descriptive study is proposed, utilising thematic analysis. The study will be implemented using a survey which will be presented in different formats (paper/online/face-to-face) depending on the stakeholder. It will investigate the perceptions of people who use AAC, family members, teaching staff and health professionals who work with AAC users. Family members, adult AAC users, teachers and health professionals will receive a link to an online survey, distributed by professional groups and charities. Parents of children attending local special schools will be given paper copies of the survey. Face to face interviews with up to 5 children who use AAC will also be carried out at local special schools, following consent from the parents. Interviews will be conducted by a trained Speech and Language Therapist using symbols to support communication via a Talking Mats style approach,and children will be accompanied by an adult. It is estimated that interviews will last between 20 and 30 minutes.
