A speech-language pathologist (SLP) is a professional who has been educated to assess speech and language development and to treat speech and language disorders. (SLP's are sometimes informally referred to as speech therapists). Speech-language pathologists can also help people with swallowing disorders. A person with the title SLP-CCC has earned the Certificate of Clinical Competence (CCC) from the American Speech and Hearing Association (ASHA) after they have earned a master’s degree, successfully completed the required clinical experiences, and passed a national exam. In addition, New York State requires school based SLP's to be certified to teach in the school system and to maintain a New York State license.
