Hearing Instrument Specialists, also called hearing aid dispensers or hearing aid practitioners, administer and interpret hearing tests, as well as select and fit hearing aids on customers. They are trained to assess hearing aid function and take earmold impressions for earmolds.
The certification requirements to be a licensed Hearing Instrument Specialist (HIS) vary by state. In general, a HIS must have a high school diploma or equivalent, must complete approximately 520 hours of training under a certified HIS trainer, must pass an examination by the International Hearing Society and specific state examination if required, and must submit an application for a Hearing Aid Specialist license through their state.
Hearing Instrument Specialists with at least 2 years of hearing aid dispensing experience can apply to be board certified through the National Board for Certification in Hearing Instrument Sciences (NBC-HIS).
Hearing Instrument Specialists typically work in retail hearing aid settings and/or can own their own business dispensing hearing aids. They may work with an Audiologist, or on their own.
