I have spoken many times with my manager (Audiologist) about this. She does not feel that there is any difference at the clinical level. As a hearing aid practitioner, I am unable to sign the prescriptions for insurance companies & VA, that is the only difference within Costco between an AuD & a HAP. There is no paediatrics, nor is there vestibular/balance testing, no tinnitus evaluations and no APD testing. We do not typically get patients w/ recent medical issues i.e. stroke, brain tumor, etc., as these patients are typically seen by an AuD within the hospital they were treated. If these patients require amplification, we often see them. Both HAPs and AuD are trained to identify red flags for referral during case history and throughout the entire comprehensive hearing testing battery.
I was required to complete a two year university program along with an extended internship (2+yrs) to gain the title of a State Licensed Hearing Aid Practitioner. This is not Costco terminology. There is no “Costco Technician”. It is a either an audiologist or a hearing aid practitioner (also called HIS, hearing aid dispenser, etc.), that has been hired or put through schooling by Costco to obtain state licensure.
