A hearing aid dispenser license comes from your state, and in some states the credential is a registration or certificate instead: IHS says hearing aid specialists are regulated by state or provincial authorities.
The route IHS describes runs through formal education or a hands-on apprenticeship, supervised training under your state's rules, written and practical exams, and a renewal cycle with continuing education.
In most states the written exam is IHS's International Licensing Examination.
What does a hearing aid dispenser license let you do?
A dispenser license is the state's permission to dispense prescription hearing aids.
FDA frames the licensed side of the market directly: prescription hearing aids are available only through a licensed hearing health care professional.
Who may order prescription hearing aids is generally set by states, not by FDA, and FDA notes that states may require ordering by physicians or audiologists.
The credential itself is the state's choice.
IHS says hearing aid specialists are regulated by state or provincial authorities and that regulations vary by jurisdiction.
Pennsylvania registers hearing aid fitters through its Department of Health, DC issues a certificate of registration, and Minnesota certifies dispensers of prescription hearing aids.
So the credential type and title — and the scope that travels with it — are whatever your state agency publishes.
FDA's over-the-counter category sits alongside that system, not instead of it.
An OTC hearing aid under 21 CFR 800.30 is an air-conduction device for adults 18 and older with perceived mild to moderate hearing impairment, sold without the supervision, prescription or involvement of a licensed person.
That category does not switch off state rules for people who present themselves as licensed: FDA's rule says a person representing themselves as a state-licensed dispenser stays subject to state and local requirements even if they handle only OTC hearing aids.
The work behind the credential is a fitting-and-service chain.
NBC-HIS's board certification exam lists the competencies it tests: assessing a patient's presenting problem and needs, testing and analyzing hearing, prescribing and analyzing hearing instruments, fitting, adjusting, programming and servicing them, and counseling, rehabilitation and professional practice.
What that work looks like day to day is the hearing instrument specialist career guide's subject — this page stays on the license itself.
Step 1: meet education minimums
Step one is education: whatever minimum your licensing agency sets for licensure, the agency publishes it in its candidate requirements.
IHS describes two ways people prepare for the field: on-the-job training, or an academic hearing instrument sciences program at a few U.S. and Canadian colleges.
IHS's own read is that most individuals enter the field through on-the-job training.
IHS also sells the structured version of that preparation: the Distance Learning for Professionals in Hearing Health Sciences course, seven units of textbook, workbook and e-learning.
In some states, IHS says, the course is a required or recommended prerequisite for licensing — but it is a course certificate, not a license.
The course ends in its own gate: a closed-book, online-proctored final of 80 questions in 120 minutes, with a 72% passing score and unlimited attempts.
Passing earns a Certificate of Completion — proof of course completion, not your state's credential.
Step 2: get a trainee or temporary permit and a sponsor
Where a state requires supervised training before licensure, that training happens under a trainee, apprentice or temporary permit — and permit titles, lengths, renewability and fees are state-specific.
IHS's ILE exam-prep page puts the supervision rule plainly: "While receiving hands-on training, you must be supervised in accordance with the laws and rules of the licensing agency where you intend to practice."
In practice that means your sponsor, your supervision rules and your permit paperwork all answer to one office — your state's.
The sponsor role is established enough that IHS publishes for it: IHS sells a Trainer Package, a trainer manual plus an online trainer toolbox, for licensed professionals who supervise trainees and apprentices.
Who qualifies to sponsor you, and how long they must have held their own license, is your agency's rule to read before you sign on anywhere.
Employers sit on the other side of that arrangement.
If you are a practice or hearing center doing the hiring rather than the training, the employer's view of the hire starts at our guide to hiring a licensed HIS.
Step 3: complete supervised hours
The supervised period is where permit-holders build the clinical judgment the exams later test.
How many hours count, and which activities count toward them, is your state's requirement to publish.
Our national research did not establish a comparable hour total across states, so the number that applies to you is the one in your agency's candidate materials.
The hours are not a formality.
IHS says ILE questions are referenced to its Distance Learning course materials and the exam is practice-based, and IHS warns that a candidate is unlikely to be successful on the ILE without clinical experience.
Step 4: pass the written (ILE) and practical exams
In most states the written exam is the International Licensing Examination for Hearing Healthcare Professionals (ILE) — a multiple-choice exam owned by the International Hearing Society, used as the written licensing exam for hearing aid specialists by most U.S. states and Canadian provinces.
The ILE runs 105 multiple-choice questions, 80 scored and 25 unscored pilot questions, with 120 minutes to complete.
You do not book it on your own initiative.
Your state or provincial licensing agency determines your eligibility, notifies IHS, and IHS then sends your scheduling instructions.
Plan the date carefully: ILE appointments can be cancelled or rescheduled free up to 48 hours before, but a change inside 48 hours forfeits the entire exam fee.
Whether your state also runs a separate practical exam — and what its stations cover — is that state's call.
Our national research did not catalog which states add a practical or what one costs, so ask your licensing agency what your exam day includes.
One note for candidates who move: if you already passed the ILE in one jurisdiction and apply in another, IHS can send official proof of your score, and some licensing agencies accept that transfer in place of a retake.
After licensure, dispensers can add a national credential on top.
BC-HIS — Board Certified in Hearing Instrument Sciences — is a voluntary certification from NBC-HIS, the National Board for Certification in Hearing Instrument Sciences, earned by passing its National Competency Exam.
It is not a license, and its eligibility is built around one: a current state or provincial dispensing license or registration, plus at least 2 years of full-time dispensing experience within the last 5 years.
NBC-HIS's eligibility also accepts a diploma from its listed programs, such as MacEwan University or George Brown College.
The NCE runs 100 scored multiple-choice items, with up to 30 unscored beta items possible, at secure computer testing sites in the U.S., Canada and some international locations.
NBC-HIS sets its passing standard with a modified Angoff method and does not publish a fixed passing percentage.
Step 5: apply, then renew with CE
Passing the exams moves you to the application, which goes to the same licensing agency that cleared your exam eligibility.
The application form, its fee and its documentation are the agency's to specify, so work from the agency's own packet rather than a generic checklist.
Renewal runs on the state's clock.
IHS's general picture is that hearing aid specialist licenses are typically renewed annually or biannually, with continuing education — your agency's renewal page carries your cycle, your CE total and your deadlines.
BC-HIS runs its own maintenance track alongside any state renewal.
Certificants revalidate annually and recertify every 3 years with 24 continuing education credits per cycle, and NBC-HIS offers no extensions, exceptions or grace period.
For U.S. holders, that CE must be approved by the American Academy of Audiology, ASHA or IHS.
Keep the two ledgers separate: your license answers to your state agency, and the certification answers to NBC-HIS.
Each body publishes its own requirements, and neither substitutes for the other.
The state owns the license; the national bodies own their exams
How long and how much
Our research found no national timeline to hand you, because the education minimum, the permit period, the supervised-hour total and the exam scheduling are each set by your state's agency.
IHS's summary of the route is the consistent part — formal education or a hands-on apprenticeship, written and practical exams, then maintenance with continuing education — but the pace is your state's, and its candidate materials are the real timeline.
The national bodies do publish their own price points.
IHS's Distance Learning course costs $789 for IHS members and $839 for non-members, rising to $1,049 and $1,119 for the full kit with the Trainer Package, as of October 2026.
NBC-HIS charges U.S. candidates a $225 new applicant/exam fee — paid again on every attempt, including retakes — plus a $299 annual fee, also as of October 2026.
What your state charges is not on any national page.
The ILE fee is not published on the IHS pages we read, and state exam, license and renewal fees are set and collected by each agency — confirm those numbers with your licensing agency before you budget.
This page is career information, not medical, legal or tax advice. Requirements, fees and exam rules change; confirm the current ones with your state's licensing agency, and with IHS or NBC-HIS for their exams and credentials.
