The CNT designation is specifically for physical therapists, occupational therapists, and speech-language pathologists. This is based on practice statements from the American Occupational Therapy Association, American Physical Therapy Association, and American Speech and Hearing Association, as well as the Core Scope of Practice from the National Association of Neonatal Therapists.  The common core knowledge (across PT, OT, and SLP) needed for safe and effective practice is assessed through the certification process.
