Speech and Language Therapist’s (SLT’s) are professionals who work with people who have communication and/or swallowing disorders. The SLT is involved in the assessment, diagnosis, intervention and development of individuals with communication and swallowing disorders. The SLT can be part of a team in developing a suitable communication system for pupils, e.g. PECS, Lámh, or alternative and augmentative communication (AAC) such as iPad speech apps and the like.
