According to the American Speech-Language-Hearing Association (ASHA) Childhood apraxia of speech (CAS) is a motor speech disorder. Children with CAS have problems saying sounds, syllables, and words. This is not because of muscle weakness or paralysis. The brain has problems planning to move the body parts (e.g., lips, jaw, tongue) needed for speech. The child knows what he or she wants to say, but his/her brain has difficulty coordinating the muscle movements necessary to say those words.

A wealth of accurate information for families and professionals is available from The Childhood Apraxia of Speech Association of North America (CASANA). Their mission statement is "To strengthen the support systems in the lives of children with apraxia, so that each child has their best opportunity to develop speech".
