Childhood Apraxia of Speech (CAS) is a condition involving difficulty with planning and programming movements for speech. With CAS, there is a disconnect between one’s ability to plan/program movements and the movements that are ultimately produced during speech. During a speech/language evaluation, it is important to differentiate between dysarthria, severe phonological disorder, and CAS, as a motor-based approach for therapy is necessary and most appropriate for CAS. This presentation discusses the key characteristics of CAS and differential diagnosis, including the use of the 5-3-3 model to differentiate between CAS and other speech sound disorders.
