The Texas Hearing Instrument Fitter and Dispenser license, issued by the Texas Department of Licensing and Regulation (TDLR) under Chapter 402 of the Texas Occupations Code, authorizes the holder to fit and dispense hearing instruments in Texas. The licensing examination behind it has three parts — a written test, a practical test, and a jurisprudence test — reached through a supervised practicum and followed by a one-year apprenticeship. The PassProfessor Texas Hearing Instrument Fitter and Dispenser program, described on the companion program page at /texas-hearing-instrument-specialist-exam-prep/, prepares candidates for that examination set.

Texas rewards candidates who read the credential as TDLR built it: a staged apprenticeship system with an examination set in its middle. A permit opens the practicum; the practicum unlocks the tests; the tests unlock the apprentice permit; and a supervised year converts the apprentice into a licensee. Nothing in the sequence can be reordered, and the examination itself is three different instruments measuring three different things — general professional knowledge on paper, clinical skill performed live, and Texas law applied online. The guide below takes each verified element in turn.
Reading the verified facts
Every fact in the table above was pinned to TDLR primary material — the Department’s examination information, its permit and apprentice pages, and its application forms — during this program’s research pass. Three reading rules apply throughout the guide. First, no passing score is printed, because TDLR does not publish one on the sources verified: the Department publishes practical pass/fail rates by fiscal year, and those rates are reported here as rates — they describe cohorts, not the standard an individual candidate must meet, and converting them into a personal target would invent a fact. Second, the three documents of the route — Temporary Training Permit, Apprentice Permit, and license — are never merged: each unlocks a different scope of supervised or independent practice, and figures belonging to one are stated only for that one. Third, vendor roles are kept exact: IHS administers the written test, PSI develops and administers the practical test under contract to TDLR, and the jurisprudence test is offered online through its own vendor — TDLR itself directs candidates with written-test eligibility questions to TDLR, not to IHS.
The route, step by step
Step one — qualify and obtain the Temporary Training Permit. Be at least 18 years of age, hold a high school diploma or certificate of equivalency, and apply to TDLR with the documentation the Department lists, including the Supervisor’s Affidavit from the licensed hearing instrument fitter and dispenser or audiologist who will supervise you. The permit is valid for one year and may be extended once, for one additional year; the permit must be obtained before supervision begins and must remain current for the whole practicum. Step two — complete the direct supervised practicum. At least 150 hours of directly supervised practicum, plus 10 hours of masking, under your supervisor — who may supervise no more than two temporary training permit holders at a time and who maintains the log of contact hours by practicum category. When the hours are complete, supervisor and permit holder submit the Supervised Practicum Affidavit, and TDLR’s approval of that affidavit is the key that opens both tests. Step three — sit the written and practical tests. IHS contacts approved candidates by email with scheduling instructions for the written test; PSI sends the eligibility email for the practical, whose Candidate Information Bulletin carries the identification, fee, content, location, and date detail candidates must read as soon as they are approved. Step four — complete the jurisprudence test online and keep the certificate: it is required before either an apprentice permit or a license can issue, the fee is $34, and the 30-day completion clock runs from payment. Step five — the Apprentice Permit and the apprenticeship year: apply, work for at least one year under a license holder’s direct or indirect supervision, and complete 10 hours of continuing education in approved subjects inside the permit year, no more than five of them online; the Department may extend the permit by up to one further year. Step six — the license: apply with the fee, the employer’s surety bond, certificate of calibration, jurisprudence certificate, and fingerprints. A candidate who does not pass a test at step three is not expelled from the route: the failed test may be retaken, with a new fee, for as long as the permit remains valid, with no limit on the number of attempts.
The outline in full
The Texas examination set has no single blueprint document a candidate can download and memorize; it has three instruments, each with its own source of truth — IHS for the written test, PSI’s Candidate Information Bulletin for the practical, and the Texas and federal law itself for the jurisprudence test. They are stated here in full, in the order a candidate meets them, because in Texas the three interlock: the practicum teaches what the practical performs, the written paper tests what the practicum taught in principle, and the jurisprudence test governs how all of it may lawfully be sold and delivered.
The written test: the International Licensing Examination
The written test is the International Licensing Examination for Hearing Instrument Dispensers, administered by the International Hearing Society, and it is the occupation’s general professional paper. Its territory is the knowledge a dispenser reasons with: the physics of sound and the anatomy and physiology of hearing; audiometric evaluation — pure tone air and bone conduction, speech audiometry, and the masking decisions that keep a test honest; hearing instrument technology, styles, and circuitry; selection and fitting grounded in measured thresholds; verification and follow-up; and the counseling through which a technically correct fitting becomes a worn one. Because Texas reserves its own law for the jurisprudence test, the written paper’s loyalty is to the profession’s shared knowledge base — which is precisely why candidates licensed or trained in other ILE states will find its register familiar, and precisely why familiarity is not the same as readiness: Texas tests this paper on top of a completed, affidavit-approved practicum, so its items land on candidates expected to have already performed the procedures the paper describes.
The practical test, part one: Audiometric
The Audiometric skills test is the examination’s centre of gravity, and TDLR’s published numbers say so. The candidate performs audiometric testing on a live model — a person of the candidate’s choice, at least 18 years old, brought to the sitting with the printed audiogram form and the release documentation the PSI bulletin specifies. What is examined is measurement as a discipline: correct procedure, correct sequence, correct recording, and the judgement calls — above all masking — that separate a threshold from a guess. This is the test on which roughly one in five Texas candidates failed in each of fiscal years 2024 and 2025 (80.65 and 81.82 percent pass rates respectively, on TDLR’s published tables), while the companion skills test ran ten or more points higher. The gap is instructive: audiometry under examination conditions punishes habits that supervised practice lets drift — hurried instructions to the model, loose transducer placement, masking applied by routine rather than by indication. Preparation for this test is therefore rehearsal, not reading: full test runs, on a real person, against the clock and the form, until the procedure is boring.
The practical test, part two: Ear Impression
The Ear Impression skills test examines the impression craft end to end: otoscopic inspection before anything enters the ear, recognition of the conditions that should stop the procedure, block placement at the correct depth, material mixed and delivered without voids or distortion, safe removal, and inspection of the finished impression against the anatomy it must reproduce. TDLR’s published pass rates — 95.18 percent in fiscal year 2025 and 92.86 percent in fiscal year 2024 — mark it as the more passable of the two skills tests, and the reason is structural: the procedure is short, sequenced, and trainable to a checklist in a way live audiometry is not. The failures that do occur are rarely knowledge failures; they are sequence and safety failures — a skipped inspection, a block placed on habit rather than on anatomy. The preparation that answers it is the practicum itself, repeated with the steps named aloud until none can be skipped silently.
The jurisprudence test: Texas and federal law, online
The third component is the one candidates most often leave to the last week, and the one whose mechanics most punish that instinct. The Texas Fitters and Dispensers of Hearing Instruments Jurisprudence Examination is based on the state and federal laws, rules, and regulations relating to the fitting and dispensing of hearing instruments — Chapter 402 and the Chapter 112 rules on the state side, and the federal hearing aid labeling and conditions-of-sale framework on the other, the same federal requirements TDLR applies to licensees and permit holders in practice. It is offered online, no authorization from the Department is needed to take it, and the certificate of completion is a hard gate: no certificate, no apprentice permit and no license, however well the other tests went. The fee is $34, paid directly to the vendor, eStrategy Solutions, Inc., and the operative trap is the clock — the test must be completed within 30 days of paying the registration fee, after which the fee and registration expire and the test is invalidated. The candidate who pays early “to get it booked” and studies late has bought an expiry date, not an examination. One mercy: the test is taken once for initial licensure and is not retaken at renewal.
How Texas reports results — and what is not published
A slower pass over the results mechanics is worthwhile, because Texas publishes an unusual amount of outcome data and very little standard data, and confusing the two misleads preparation. Test results are sent to the candidate’s mailing address on file when they become available — a reason TDLR gives for keeping contact information current, since a result sent to a stale address is a delay the candidate built themselves. What TDLR publishes publicly is cohort performance on the practical test, by fiscal year: in fiscal year 2023, Audiometric at 83.33 percent and Ear Impression at 94.34 percent; fiscal year 2024, 80.65 and 92.86 percent; fiscal year 2025, 81.82 and 95.18 percent, with no-show counts published alongside. What TDLR does not publish on the sources verified is a pass mark — no percentage or score a candidate must reach on any of the three components appears in this guide, because none was found in the Department’s published examination material. The practical rates should be used the way this guide uses them: to allocate preparation effort between two skills tests of demonstrably different difficulty, not to estimate a personal probability.
The sittings themselves
Each Texas component is sat differently, and the candidate should rehearse each format as a format. The written test is scheduled through IHS once eligibility is approved: IHS contacts the candidate by email, fees are paid directly to IHS on registration, and a stale email address on file with TDLR is therefore a scheduling failure waiting to happen. The practical test runs through PSI: the eligibility email follows TDLR’s review, and the Candidate Information Bulletin — ID requirements, fees, content, locations, dates — is the governing document for the sitting, to be read closely as soon as approval arrives. The practical carries physical logistics no other component has: the printed audiogram form, the bulletin’s release documentation, and a model at least 18 years old who has agreed to be tested, all arranged by the candidate. The jurisprudence test is sat online, alone, on the candidate’s own timing inside its 30-day window, with the certificate available on completion — the only Texas component with no venue, and the only one that can expire unattempted. Results for the written and practical tests are sent to the mailing address on file when available. None of the three is a walk-in: each begins with an approval, an email, or a payment whose downstream clock the candidate owns.
A study plan built on how this examination is actually put together
Build the plan in the order the evidence weights the risk. First, audiometric performance — the practical test TDLR’s own tables identify as the harder one: full test runs on a real model, masking decisions made and defended aloud, the audiogram form completed exactly as PSI requires, until the procedure survives nerves. Second, the ear impression sequence — shorter to build, unforgiving of skipped steps: inspection, block, material, removal, inspection again, rehearsed as one unbroken chain. Third, the written syllabus — the ILE’s professional knowledge, studied against the practicum the candidate has just completed, so every principle is tied to a performed memory rather than to prose alone. Fourth, Texas and federal law — Chapter 402, the Chapter 112 rules, and the federal labeling and conditions-of-sale framework, studied as the jurisprudence test’s named territory and finished before the jurisprudence fee is paid, so the 30-day window contains a sitting, not a study course. Fifth, the administrative rehearsal — affidavit approved, emails current with TDLR, PSI bulletin read, model confirmed, jurisprudence certificate filed: the details that void sittings without testing knowledge at all. Woven through all of it, the plan respects the sequence Texas imposes: examination study peaks after the practicum, because that is the first moment Texas allows the tests to be taken.
The working method: turning the outline into a performance
Texas preparation fails most often as a modality problem: candidates study a performance examination as if it were a reading examination. The working method that answers it has four parts. Perform weekly, from the practicum onward. Full audiometric runs and full impression sequences, done on real people with the real forms, with every deviation from procedure named and corrected on the spot — the practicum’s 150 hours are the raw material, and deliberate rehearsal is what refines them into examination performance. An error log keyed to the three components. Every missed written item, botched masking decision, skipped impression step, and misremembered rule of Texas law filed under its component — written, audiometric, ear impression, jurisprudence — so that after a month the log, not the candidate’s confidence, assigns the remaining study. Law learned as scenarios. The jurisprudence territory applied to situations — a sale, a label, a record, a supervision question — because the test examines the law of a working practice, and because the same law will govern the apprenticeship year that follows. Administrative dry runs. Before each sitting, walk its checklist cold: eligibility email received, bulletin read, model confirmed and consented, forms printed, address and email current with TDLR, jurisprudence window calendared from the day of payment. Texas voids more candidacies through paperwork than through audiometry, and paperwork is the easiest failure to rehearse away.
The errors this examination is built to catch
The Texas set catches a recognisable set. Studying the practical tests as theory — knowing how masking works without having masked, under observation, fifty times — meets an examination that watches the candidate’s hands. Treating the two skills tests as one concedes the audiometric test’s published difficulty; TDLR’s own tables have shown the same ten-plus-point gap for three consecutive fiscal years. Paying the jurisprudence fee early starts a 30-day clock that expires unattempted, and the resulting invalidated test must be re-registered and repaid. Letting the practicum drift — hours unlogged, categories unbalanced, the affidavit left to the permit’s final month — delays eligibility for every component at once, because nothing can be sat before the affidavit is approved. Ignoring the vendors’ documents: IHS schedules the written test and PSI’s bulletin governs the practical, and candidates who wait for TDLR to explain either discover that the explanation was published, by the vendor, all along. And arriving without the model, the printed audiogram, or the release documentation converts a prepared candidate into a no-show — TDLR publishes no-show counts alongside its pass rates for a reason.
The credential in one view
The Texas Hearing Instrument Fitter and Dispenser license in one view is a chain of supervised trust. A permit holder learns the craft at a licensee’s side for 150 measured hours; the state then tests the learning three ways — what the candidate knows, what the candidate can do, and whether the candidate knows the law the doing is governed by; a year’s apprenticeship converts the tested candidate into a practitioner under a senior’s eye; and only then does Texas hand over the independent credential. The examination set sits at the hinge of that chain, and it is built in the chain’s own image: the written test certifies the knowledge the practicum taught, the practical certifies the hands the practicum trained, and the jurisprudence test certifies that the new apprentice knows the legal frame the apprenticeship will operate inside. The candidate who studies the three components as one event at three registers — principle, performance, and law — finds them reinforcing each other: audiometric theory explains masking practice, impression practice explains fitting outcomes, and the jurisprudence material explains why the whole sequence is supervised in the first place.
After the sittings: the apprenticeship and the license
Passing the written and practical tests does not end the Texas route; it changes the candidate’s title. With the jurisprudence certificate in hand, the candidate applies for the Apprentice Permit and begins the apprenticeship year — work under a license holder’s direct or indirect supervision, with 10 hours of continuing education in approved subjects completed inside the permit year (no more than five online), periodic formal evaluation by the supervisor, and the permit extendable by up to one further year if the Department allows. Only at the end of that year does the full application go in — fee, employer’s surety bond, certificate of calibration, jurisprudence certificate, fingerprints — and the Hearing Instrument Fitter and Dispenser License issue. The licensee then practices under the same Chapter 402 and Chapter 112 framework the jurisprudence test examined, with the federal labeling and conditions-of-sale rules applying to the licensee’s daily work, and with one small, earned relief: the jurisprudence test taken for the initial license is not retaken at renewal. The dispenser who treats the apprenticeship as the examination’s final, longest section — supervised practice, formally evaluated — arrives at independent licensure already working the way the license expects.
Frequently asked questions
Which TDLR sources govern the Texas route?
The Department’s examination information page for the three components and their administrators, its Temporary Training Permit and Apprentice Permit pages and forms for the route’s stages and hours, and the PSI Candidate Information Bulletin for the practical sitting’s own rules. Candidates should read the bulletin as soon as PSI confirms eligibility.
Why does the practicum come before the examinations in Texas?
Because TDLR makes it the eligibility key: approval for both the written and the practical test follows completion of the direct supervised practicum and approval of the Supervised Practicum Affidavit. The design tests candidates on skills they have already practised under supervision — the examinations audit the practicum rather than predict it.
What do TDLR’s published practical pass rates actually tell a candidate?
Cohort outcomes, not a personal standard. Across fiscal years 2023–2025 the Audiometric test’s pass rate ran 80.65–83.33 percent and the Ear Impression test’s 92.86–95.18 percent. Used properly, the tables allocate preparation: the audiometric performance has been the harder test every year published, by a wide and stable margin.
Is there a published Texas passing score I should aim at?
No pass mark for any component was published on the TDLR sources verified for this guide, and none is printed here. The honest target is the syllabus and the performed skills at working standard; any percentage quoted by third-party material for these tests should be treated as unverified.
How does the jurisprudence test’s 30-day rule work in practice?
The clock starts at payment. Pay the $34 vendor fee only when ready to complete the test promptly; after 30 days the fee and registration expire and the test is invalidated, requiring re-registration and a new fee. The certificate itself is then required before an apprentice permit or license can issue — and, once taken for the initial license, the test is not retaken at renewal.
What should I do after an unsuccessful practical attempt?
Use TDLR’s retake rule as it is written: there is no limit on retakes while the temporary training permit (or the out-of-state license relied on) remains valid, with a new fee each time. Rebuild against the component that failed — audiometric failures call for supervised live rehearsal, not more reading — and protect the permit’s validity, because the retake right lives and dies with it.
Who schedules what — TDLR, IHS, or PSI?
TDLR approves eligibility; IHS then contacts the candidate by email to schedule the written test, and its fees are paid directly to IHS. PSI confirms practical eligibility by email and administers that test under its Candidate Information Bulletin. The jurisprudence test needs no one’s authorization: it is taken online through its vendor when the candidate chooses, inside its 30-day post-payment window.
Does the examination test diagnosis or treatment of ear disease?
No. TDLR states the jurisprudence examination’s content may not test knowledge of the diagnosis or treatment of any disease of or injury to the human body, and the credential itself is a fitting and dispensing license, not a diagnostic one. Recognizing when a presentation must be referred out is part of lawful dispensing practice; diagnosing it is not the dispenser’s examined role.
Can an out-of-state license holder skip the Texas practical test?
No. The out-of-state applicant must pass the Texas practical test before a Texas license issues, alongside proof of passing the written test, the jurisprudence certificate, the employer’s surety bond, the certificate of calibration, and fingerprints.
How is the apprenticeship year assessed?
The apprentice works under a license holder’s direct or indirect supervision for at least one year; the supervisor periodically conducts a formal evaluation of the apprentice’s progress in developing professional skills, is responsible for the services the apprentice provides to clients, and the apprentice completes 10 hours of continuing education in approved subjects inside the year, no more than five of them online.
Is PassProfessor affiliated with TDLR, IHS, or PSI?
No. PassProfessor is an independent preparation provider. TDLR alone licenses; IHS and PSI administer their components under their own arrangements with the state.
