Hi csb001 and jay_man2
This answers many of my questions. From my reading, here is the hierarchy of the discipline (at least as I understand it):
ENT: This is an MD that specializes in diagnosing and treating medical problems (pathology) that involve the Ear, Nose and Throat.
AuD: Doctor of Audiology. These are very highly trained medical professionals, who have somewhat less training than an MD. They specialize in testing and evaluating a patient’s hearing, and recommending and dispensing hearing aids.
HIS: Hearing Instrument Specialist (HIS). This is a state licensed professional with education and experience (less education than an AuD) in recommending and dispensing hearing aids. An HIS performs many of the same tasks as an AuD.
The CCC-A (Certificate of Clinical Competence - Audiology) and FAAA (Fellow of American Academy of Audiology) are professional certifications received after the basic degree process is completed, and demonstrate additional training and experience.
To our hearing professionals, please let me know if I’ve gotten any of this wrong. Thanks!
