The Iowa Hearing Aid Specialist license, issued under Iowa Code chapter 154A by the Department of Inspections, Appeals, and Licensing (DIAL), authorizes the holder to fit, dispense, and sell hearing aids in Iowa. Iowa’s current rules require a written examination only — the national examination through the International Hearing Society (IHS), verified under IAC 481—2060.4, with the Praxis Examination in Audiology as the audiology-route alternative — and no separate state practical or law examination. The PassProfessor Iowa Hearing Aid Specialist program, described on the companion program page at /iowa-hearing-instrument-specialist-exam-prep/, prepares candidates for the examination Iowa actually requires.

Iowa rewards candidates who read the credential as the Department now administers it: a department-run license — not a board-run one — with a supervised training tier, a single national written gate, a direct-verification rule for the result, and a biennial education cycle that carries the state’s law content after licensure rather than before it. Almost every error candidates make in Iowa comes from material written for the older structure: a board that no longer exists, a one-year permit that is now two years, a 32-hour education duty that is now 24. The guide below takes each verified element in its current form.
Reading the verified facts
Every fact in the table above was pinned to Iowa primary material in its current form — IAC 481 chapter 2060 as re-adopted effective June 18, 2025 (ARC 9285C), chapter 2061 as amended the same day (ARC 9286C), the fee rule at 481—507.7, Iowa Code chapter 154A, and DIAL’s own application pages — during this program’s research pass. Three reading rules apply throughout the guide. First, no passing score is printed, because Iowa does not publish one in the sources verified: the rules require verification of passing the national examination and state no number, so no number appears here; any percentage quoted by third-party material for this examination should be treated as unverified. Second, the current rules outrank older Department text wherever the two differ: DIAL’s public application pages still carry, in places, the superseded one-year temporary permit description and a 32-hour continuing education figure in endorsement text. This guide follows the rules — two-year permit, 24 hours — and flags each superseded figure where a candidate is likely to meet it. Third, the authority is the Department, full stop: the Board of Hearing Aid Specialists was eliminated by 2024 Senate File 2385 and its functions transferred to DIAL, so no passage in this guide presents a board as the credential’s current authority, and candidates should treat board-directed instructions in older material as historical.
The route, step by step
Step one — enter training under the Temporary Permit, where that is the path in. Submit the online application and the $42 nonrefundable fee (IAC 481—507.7(3)), with the employer’s statement the rules require: the type of supervision to be provided, a list of the subjects to be covered, and the books and other training materials to be used. The supervisor must hold a current hearing aid specialist license valid for the preceding 24 months, have two years of actual experience in testing, fitting, and dispensing of hearing aids, supervise no more than three trainees at the same time, and provide a minimum of 20 hours of direct supervision during the trainee’s first 90 days. The permit is valid for two years and shall not be renewable — Senate File 2385 doubled the former one-year term, and the two years are the whole training frame. The Department reserves the right to deny a temporary permit application or rescind a permit. Step two — pass the qualifying examination. Iowa Code §154A.10 states the licensure conditions together: the applicant successfully passes the qualifying examination prescribed in §154A.12, is free of contagious or infectious disease, and pays the necessary fees set by the Department. Under the current rules the examination condition is verified by passing the national examination through IHS — the standardized IHS licensing examination — or, on the audiology route, the Praxis Examination in Audiology through ETS. Step three — have IHS verify the result directly. DIAL’s permanent-license instructions require the applicant to request that IHS submit evidence of successfully completing the examination, including the final score, directly to the Department, and state expressly that the score report must be transmitted directly from IHS. Build this request into the examination week, not the application week. Step four — apply for the permanent license. Submit the completed online application and the $156 application fee; an applicant who held a temporary permit attaches the complete temporary permit schedule for supervision form. Step five — licensure, and the start of the biennial cycle described below. Applicants licensed in another state use licensure by endorsement under §2060.5 instead: an online application and fee, verification of licensure in the other jurisdiction, evidence of meeting examination-side requirements on the rule’s terms — including a passing score on the national examination, an examination the Department determines is equivalent, or current certification from the National Board for Certification in Hearing Instrument Sciences — and evidence of a minimum of 24 continuing education hours within the 24 months before application, or certificates verifying the home state’s requirement was met.
The outline in full
Iowa’s examination requirement has one instrument for the dispensing route — the national IHS examination — and one statutory scope statement behind it, §154A.12, which tells the candidate exactly what the qualifying examination is designed to demonstrate. They are stated here together, because in Iowa the statute is the syllabus’s frame: the national paper supplies the items, and §154A.12 supplies the three knowledge areas those items must evidence.
The statutory scope: what the examination must demonstrate
Section 154A.12 provides that the examination required by chapter 154A shall be designed to demonstrate the applicant’s adequate technical qualifications, including — but not limited to — three areas. (a) The technical core: evidence of knowledge in areas such as the physics of sound, the anatomy and physiology of hearing, and the function of hearing aids, as these areas pertain to the fitting or selection and sale of hearing aids. The closing qualifier does real work: Iowa examines hearing science as it bears on fitting, not as abstract audiology — acoustics in the service of thresholds and gain, anatomy in the service of impressions and referrals, instrument function in the service of selection. (b) The referral map: evidence of knowledge of the medical and rehabilitation facilities available in the area served, for children and adults who have hearing problems. (c) The limits of fitting: evidence of knowledge of situations in which it is commonly believed that a hearing aid is inappropriate. The section then closes with the credential’s defining limitation: the Department shall not require the applicant to possess the degree of professional competence normally expected of physicians. Read as a whole, §154A.12 describes a practitioner examined deeply inside a bounded scope — deep enough to fit safely and to recognize the boundary, never examined as if the boundary were not there.
The national examination through IHS: the single gate
The current rules verify the §154A.12 scope through one instrument for the dispensing route: “the national examination through IHS,” defined in §2060.1 as the standardized licensing examination of the International Hearing Society or its successor organization — the ILE. Its territory is the profession’s shared knowledge base at licensing depth: sound and hearing science; audiometric evaluation in full — pure tone air and bone conduction, speech audiometry, masking, audiogram interpretation; hearing instrument technology, styles, and electroacoustics; selection, fitting, and verification reasoning; ear impression knowledge examined as procedure-in-writing; counseling and follow-up; and the referral and red-flag judgement that §154A.12(b) and (c) name directly. Two Iowa-specific mechanics govern how the result functions. First, the attempt ceiling: the applicant may not take the national examination through IHS more than six times without Department approval (§2060.4(2)(a)) — a rule that converts attempt management into part of the candidacy. Second, direct verification: the passing result reaches the Department from IHS itself, including the final score, at the applicant’s request; the candidate’s own copy of a score report is not the verification the rule contemplates. The Praxis alternative in §2060.4(2)(b) belongs to the audiology route — candidates entering through audiology education verify with the Praxis Examination in Audiology through ETS — and dispensing-route candidates should not treat the two as interchangeable options to shop between; they are the verification instruments of two different entry routes into the same license.
What Iowa does not require — stated plainly
Candidates transferring from other states routinely prepare for examinations Iowa does not set, so the negative space deserves its own statement. No practical examination: nothing in IAC 481—2060 conditions licensure on a state practical sitting — no audiometric performance test, no ear impression sitting, no instrumentation bench. The performed craft matters in Iowa practice and inside the supervised training period, and the written paper examines its principles in scenario form, but there is no Iowa practical to book, and any vendor offering one under Iowa’s name should be treated with suspicion. No law examination: nothing in the current rules conditions licensure on a separate Iowa law or jurisprudence test. Iowa law is instead carried into the license’s maintenance: the biennial continuing education rule reserves a minimum of two hours, every biennium, for Iowa hearing aid specialist law and rules, or ethics (§2061.2). The distinction matters for study allocation: a candidate who spends the examination season drilling Iowa statutes for a law sitting that does not exist is spending the national paper’s preparation time — while a licensee who ignores the two-hour law component at renewal has missed the place Iowa law actually lives in this credential.
The supervised period: training inside a two-year frame
The temporary permit period deserves a slower pass, because Senate File 2385 changed its shape and older guidance misdescribes it. The permit’s purpose is definitional: it is issued while the applicant is in training to become a licensed hearing aid specialist. Its application builds the training plan into the permit itself — the employer’s statement must describe the supervision type, list the subjects to be covered, and name the books and training materials to be used — so the Department approves a programme of training, not merely an employment relationship. The supervisor standards are equally specific: a license held currently and valid for the preceding 24 months; two years of actual experience in testing, fitting, and dispensing; no more than three trainees at once; and a floor of 20 hours of direct supervision in the first 90 days, when the trainee’s habits are forming. The term is two years, not renewable — extended from one year by the 2024 legislation precisely to give trainees more supervised time — and when the trainee applies for the permanent license, the completed supervision schedule form travels with the application as the record of that training. The design is coherent: Iowa widened the training window while keeping its examination to one rigorous written gate, which places the burden of practical formation on supervised practice and the burden of certification on the paper. The trainee who understands that division uses the two years to build both the experience the form records and the knowledge the examination scores.
A study plan built on how this examination is actually put together
Build the plan around the single gate. First, the technical core at fitting depth — sound, hearing anatomy and physiology, and instrument function studied exactly as §154A.12 frames them: every principle tied to a fitting, selection, or sale decision, because that is the register the qualifying examination is designed to test. Second, audiometric reasoning in writing — thresholds, configurations, and above all masking decisions worked as written scenarios with the reasoning stated, since Iowa examines the procedure’s logic on paper rather than its performance in a booth. Third, the boundary strands as first-class subjects — the medical and rehabilitation facilities map and the situations where a hearing aid is inappropriate, drilled until referral is a reflex; in a one-paper state, §154A.12(b) and (c) are not garnish, they are two of the statute’s three named areas. Fourth, attempt pacing — the first sitting taken when the syllabus is covered at working depth, not as a diagnostic, because six attempts is a ceiling with a Department-approval condition beyond it, not an invitation. Fifth, the administrative rehearsal — the direct-transmission request to IHS made in examination week, the supervision schedule completed and attached, the application fee and form ready: the mechanics that convert a pass into a license. Leave Iowa-law cramming out of the examination season entirely; its place in this credential is the renewal cycle, and the plan that respects that placement is the plan shaped like the rules.
The working method: turning supervised training into written performance
Iowa preparation fails most often as a translation problem: the trainee’s knowledge lives in performed routines, and the examination asks for it in written, reasoned form. The working method that answers it has four parts. Write the procedure, weekly. After supervised sessions, the day’s procedures — a masking call, an impression decision, a fitting rationale — written out as scored answers with reasons, until the reasoning that supervision built in the hands exists on paper in the candidate’s own words. An error log keyed to §154A.12. Every missed practice item filed under the statute’s three areas — technical core, referral map, limits of fitting — so that after a month the log, not the candidate’s confidence, assigns the remaining study. Boundary drills. Presentations and audiograms sorted rapidly into fit / refer / fit-with-conditions, with the facility or specialist named for every referral, because §154A.12(b) examines the destination as well as the decision. Calendar discipline. The permit’s two-year expiry, the examination sittings, the IHS transmission, and the application kept on one calendar; Iowa’s route has few moving parts, and every one of them is the candidate’s to schedule.
The errors this examination is built to catch
The Iowa route catches a recognisable set. Preparing for a practical that does not exist — or worse, paying for one — while the single real gate goes under-prepared. Studying to superseded structure: writing to a board Iowa abolished in 2024, planning around a one-year permit, budgeting 32 hours of continuing education — each error individually small, together a candidacy built on a state that no longer exists. Treating the written paper as a knowledge quiz rather than as examined judgement: §154A.12’s second and third areas test where the candidate sends people and when the candidate refuses to fit, and recall-only preparation leaves both unbuilt. Burning attempts as reconnaissance against a six-attempt ceiling that requires Department approval beyond it. Passing and stalling: the score report that is never requested from IHS, the supervision schedule never attached — a candidacy that cleared its only examination and still did not become a license. And ignoring the two-hour law component’s actual location — at renewal, every biennium — while drilling statutes for an initial law test Iowa does not set.
The credential in one view
The Iowa Hearing Aid Specialist license in one view is supervised formation certified by a single rigorous paper. A trainee learns the craft for up to two years under a supervisor whose standing, experience, and direct-supervision hours the rules themselves specify; the state then certifies the result once, in writing, through the profession’s national examination aimed at the three knowledge areas its own statute names — how hearing and instruments work, where help beyond the fitting room lives, and when not to fit; and the license that follows runs on a biennial cycle in which Iowa reserves two hours of every renewal for its own law. The structure is honest about its division of labour: practice is formed in practice, knowledge is certified on paper, and law is maintained for life. The candidate who studies in that image — procedures reasoned in writing, boundaries drilled as reflexes, mechanics executed on time — finds the single gate less narrow than it first appears, because everything the route built points at it.
After the sitting: the license and its clocks
The pass becomes a license only when its paperwork completes: IHS’s direct transmission received, the online application and $156 fee filed, the supervision schedule attached where a permit was held. The license then runs on the biennial clock — renewal period January 1 of each odd-numbered year through December 31 of the next even-numbered year, a $60 renewal fee, a $60 late fee inside the grace period, and reactivation at $120 for a license let go inactive, with the continuing education evidence reactivation requires. The education duty itself — 24 hours per biennium including the two law-and-rules or ethics hours, with up to 12 excess hours carried forward — is planned from the first year rather than remembered in the last month. A licensee issued within six months of the renewal date skips that renewal and renews at the next cycle two years later. The specialist who treats licensure as the start of a documented biennial practice meets each of those clocks as a formality — and keeps the Department, not a board, as the authority whose current rules set every one of them.
Frequently asked questions
Which Iowa sources govern this route?
Iowa Code chapter 154A — principally §154A.10 (issuance) and §154A.12 (scope of examination) — together with IAC 481 chapter 2060 (licensure), chapter 2061 (continuing education), and the fee rule at 481—507.7, all administered by the Department of Inspections, Appeals, and Licensing. Candidates should work from the current chapters: chapter 2060 was re-adopted effective June 18, 2025.
I found references to the Iowa Board of Hearing Aid Specialists. Is it still the authority?
No. The Board of Hearing Aid Specialists was eliminated by 2024 Iowa Acts, Senate File 2385, and its functions were transferred to the Department of Inspections, Appeals, and Licensing. The re-adopted chapter 2060 systematically replaces board references with the Department. Any material directing you to apply to, or be examined by, that board is describing the pre-2025 structure.
Why does the Praxis Examination appear in an Iowa dispensing guide?
Because the licensure rule names it: IAC 481—2060.4(2) verifies the examination requirement by either the national examination through IHS or the Praxis Examination in Audiology through ETS. The Praxis is the audiology route’s instrument; the IHS examination is the dispensing route’s. They are alternatives between routes, not options within one route.
What does “no more than six times” mean in practice?
Section 2060.4(2)(a) provides that an applicant may not take the national examination through IHS more than six times without Department approval. Six unsuccessful attempts exhaust the unapproved allowance; a seventh requires the Department’s approval first. Pace attempts accordingly — sit when prepared, and rebuild from each result rather than resitting on hope.
My temporary permit paperwork says one year. Which is right?
The current rules. Senate File 2385 extended the temporary permit from one year to two years to allow additional supervised training time, and §2060.2(2) now provides that a temporary permit is valid for two years and shall not be renewable. DIAL’s public temporary-permit page still carried the one-year description when this guide was verified; the rule governs.
How many continuing education hours does Iowa require — 24 or 32?
Twenty-four per biennium under the current rule (IAC 481—2061.2, as amended effective June 18, 2025), including at least two hours in Iowa law and rules, or ethics, with carryover of up to 12 excess hours. The 32-hour figure belongs to the superseded rules and still surfaces in older Department text, including endorsement material; the current endorsement rule itself requires evidence of 24 hours in the prior 24 months.
What should I do after an unsuccessful examination attempt?
Rebuild against the §154A.12 areas the result exposes, inside the attempt allowance and the permit’s remaining life, and protect the mechanics: the retake, the direct IHS transmission once passed, and the application are one sequence. An unsuccessful attempt changes the study plan; it does not change the route.
Is there a published Iowa passing score I should aim at?
No pass mark for the national examination was published in the Iowa rules or Department material verified for this guide, and none is printed here. The honest target is the §154A.12 territory at working depth, in written form.
Is PassProfessor affiliated with DIAL or IHS?
No. PassProfessor is an independent preparation provider. The Department alone licenses; IHS stands behind the national examination and transmits its results.
When does enrollment open for the PassProfessor program?
The program is in the works and enrollment is not yet open. Leave an email address on this page and PassProfessor will write to you when the program is ready — and only about this program.
