Graduate coursework in audiology includes anatomy, physiology, physics, genetics, normal and abnormal communication development, diagnosis and treatment, pharmacology, and ethics.

Audiologists must be licensed in all states; requirements vary by state. For specific requirements, contact your state’s licensing board for audiologists.
Audiologists can earn the Certificate of Clinical Competence in Audiology (CCC-A), offered by the American Speech-Language-Hearing Association. They also may be credentialed through the American Board of Audiology. Although it is not required, certification may satisfy some or all of the requirements for licensure and may be required by some employers.
