The Licensed Hearing Instrument Specialist credential, issued by the Connecticut Department of Public Health under Chapter 398 of the Connecticut General Statutes, authorizes the holder — a person other than an audiologist or physician — to engage in the practice of fitting or selling hearing aids in Connecticut. The licensing examination behind it is given by the Department and consists of written, oral, and practical parts, offered at least twice yearly. The PassProfessor Connecticut Licensed Hearing Instrument Specialist program, described on the companion program page at /connecticut-hearing-instrument-specialist-exam-prep/, prepares candidates for that examination.

Connecticut rewards candidates who read the credential as Chapter 398 built it: a short statute that defines a practice, gates it with an examination the Department itself gives in three formats, and then surrounds the licensee with consumer-protection duties that are part of the same practice. The definition in section 20-396 is the syllabus in miniature — comprehensive measurement of human hearing, screening for listed otological disorders, impressions for earmolds, selection and adaptation of hearing aids, instruction and counseling. The examination tests that definition in writing, in speech, and in performance; the sections that follow the definition in the chapter then govern the licensee’s sales, receipts, referrals, and records for the whole working life of the license. The guide below takes each verified element in turn.
Reading the verified facts
Every fact in the table above was pinned to Connecticut primary material — the current text of Chapter 398 on the General Assembly’s official site, and the Department of Public Health’s own licensing packet for this credential — during this program’s research pass, re-verified first-hand on November 10, 2026. Three reading rules apply throughout the guide. First, no numerical passing score is printed, because no Connecticut source verified publishes one: section 20-398 requires that the applicant has “satisfactorily passed” the examination, and that is the standard in its published form; any percentage quoted by third-party material for this examination is unverified. Second, the written examination’s identity is attributed exactly as its source attributes it: the statute says only a written, oral, and practical examination given by the Department, while the Department’s packet identifies the written part as the International Licensing Examination developed by the International Hearing Society — the guide keeps those two statements distinct rather than merging them into a claim neither source makes alone. Third, the three Connecticut documents — Temporary Permit, specialist license, and audiology license — are never merged: each authorizes a different person, or the same person in a different capacity, to do a different scope of work.
The route, step by step
Step one — the education proof. Show the Department satisfactory proof of a four-year course at an approved high school, or of an equivalent education as the Department determines it. This proof is also the entry ticket for the Temporary Permit, so assemble it first. Step two — the course of study or the approved training. Complete, satisfactorily, a course of study in the fitting and selling of hearing aids, or a period of training approved by the Department. Step three — supervised practice under the Temporary Permit, if you use it. For $60, the permit holder with the education proof may fit or sell hearing aids for one year under the direct supervision and training of a licensed hearing instrument specialist or a licensed audiologist, or while enrolled in an approved course of study — without making selections of hearing aids. If the licensing examination has not been passed within the year, the permit may be renewed once, for $60; there is no second renewal in the statute, which makes the permit a clock, not a status.
Step four — apply and sit. Apply for the examination on the Department’s prescribed forms, pay the $200 examination fee section 20-398 sets, and sit at one of the sittings the Department gives at least twice yearly: the written examination, and the oral/practical examination with its ear-impression and full-audiometric sections. Step five — the license. On satisfactory passage and payment of the $255 initial license fee under section 20-398, the Department issues the Licensed Hearing Instrument Specialist license. The out-of-state side door, stated exactly: under section 20-399 the Department may license without a qualifying examination an applicant holding a current, unsuspended, and unrevoked license from a state or jurisdiction the Department determines has equivalent or higher requirements and an equivalent or stricter qualifying program — and it may not do so for an applicant with disciplinary action pending or an unresolved complaint. That is the Department’s determination to make, not the applicant’s assumption to rely on.
The outline in full
Connecticut publishes no single blueprint document for this examination. What it publishes is better evidence than a blueprint summary: a statutory definition of the practice, a packet that names the written paper and describes the two performed sections, and a chapter whose operative sections state the law the licensee practices under. The outline below is built from those three sources, in the order a candidate meets them, because in Connecticut they interlock — the definition tells you what the written paper is about, the performed sections test the definition’s two physical skills, and the chapter’s consumer-protection sections test whether the candidate can sell what they can fit.
The written examination: the International Licensing Examination
The Department’s packet identifies the written examination as the International Licensing Examination (ILE) for Hearing Instrument Dispensers, developed by the education division of the International Hearing Society, and points candidates to the IHS study guide for it. Its territory is the profession’s shared knowledge base, read against Connecticut’s own definition of the practice: the physics of sound and the anatomy and physiology of hearing; audiometric evaluation as the comprehensive measurement of human hearing; hearing instrument technology, styles, and circuitry; selection and adaptation grounded in measured hearing; and the instruction and counseling in use that section 20-396 names as part of the practice itself. Because Connecticut reserves no separate state-law paper in the sources verified, the written paper’s loyalty is to that shared base — which is why candidates trained in other ILE states will find its register familiar, and why familiarity is not readiness: Connecticut examines the same knowledge in a candidacy that must also survive two performed sections given by the Department itself.
The oral/practical examination, part one: the full audiometric examination
In one oral/practical section, the packet says, the candidate will be expected to perform a full audiometric examination. The word “full” does the work in that sentence. What is examined is measurement as a complete discipline: preparing and instructing the person being tested, correct transducer placement, a correct and complete threshold procedure, the masking judgments that keep a result honest when the ears would otherwise be confused, and recording that another practitioner could rely on. It is oral as well as practical — the candidate performs and answers for the performance — so a procedure done from silent habit, without the reasons at the candidate’s command, is only half performed. Preparation for this section is therefore rehearsal with narration: full examinations, on real people, with each decision named aloud as it is taken, until the sequence survives both nerves and questioning.
The oral/practical examination, part two: the ear impression
In the second section the candidate will be expected to make an ear impression — the physical act at the center of the earmold work section 20-396 names. The examined sequence runs: otoscopic inspection before anything enters the ear, recognition of the conditions that should stop the procedure — the same family of findings section 20-403 requires the licensee to act on in a consumer — block placement at a safe and correct depth, material mixed and delivered without voids or distortion, safe removal, and inspection of the finished impression against the anatomy it must reproduce. The failures this section catches are rarely knowledge failures; they are sequence and safety failures, an inspection skipped or a block placed from habit. The preparation that answers it is the sequence rehearsed as one unbroken chain, with the steps named, until none can be omitted silently.
The law inside the practice: Chapter 398 as working knowledge
Connecticut’s third territory is not a separate sitting; it is the chapter itself, and it is examined by the license the candidate is asking for. Referral first: section 20-403 names eight histories — ear deformity, recent drainage, sudden or rapidly progressive loss, dizziness, sudden or recent unilateral loss, a fifteen-decibel air-bone gap at the three named frequencies, cerumen or a foreign body, and recent ear pain — and requires the specialist to advise a consumer with any of them to consult a physician or otolaryngologist before fitting, with a written statement of the advice accompanying the sale. The sale itself: section 20-402a gives every purchaser a thirty-day trial, with free adjustment or return of the full purchase price on a timely return, a cancellation fee capped at twelve percent, and prescribed capital-letter disclosures in receipts and contracts, including the deposit-refund rule when a hearing aid cannot be inspected within forty-five days. The paper trail: the receipt must carry the delivery date, the licensee’s signature, business address and license number, the aid’s serial and model numbers, the full terms of sale and warranties, and whether the aid is new, used, or reconditioned; the underlying records, including each purchaser’s audiogram, are retained for three years. The protected sale: a hearing aid may not be sold to a person under eighteen without a prior ear examination by an otolaryngologist and an audiological examination performed or supervised by an audiologist, nor fitted for a person with a recent ear infection history without the required otolaryngologist examination. A candidate who treats these as post-licensing reading has the order backwards: they are the conditions under which everything the other two territories produce may lawfully be sold.
How Connecticut states the passing standard — and what is not published
A slower pass over the standard is worthwhile, because Connecticut’s form of it is frequently misreported. Section 20-398 says the applicant must have “satisfactorily passed a written, oral and practical examination given by the department.” No percentage, scaled score, or per-section mark appears in the statute, and none was found in the Department’s packet or continuing-education material verified for this guide — so none is printed here. That is not a gap in this guide; it is the state’s published position. The honest preparation target it produces is demanding in a different way: with no number to aim at, the candidate must prepare each part to a working standard rather than to a rumored threshold, and must treat the oral/practical sections — where performance is observed directly — as pass-or-fail performances, not as formalities attached to the written paper. Any source that quotes a Connecticut percentage for this examination should be asked for its official citation; on the sources verified, there is none to give.
The sittings themselves
Connecticut’s examination is a calendar event, not an on-demand appointment: the statute guarantees sittings at least twice yearly, application is on the Department’s own forms, and the $200 examination fee is the statute’s figure. Rehearse each format as a format. The written sitting is a knowledge paper taken under timed, closed conditions — the ILE the Department’s packet identifies — and its discipline is pace and coverage. The oral/practical sitting is performed work in front of examiners: a full audiometric examination and an ear impression, each liable to questioning as it proceeds, so arrive with the equipment habits, the sequence, and the vocabulary all rehearsed together. The administrative sitting begins before either: forms complete, education and training proof in the Department’s hands, the Temporary Permit’s year — if the candidate is working under one — still running, with its single renewal unused or accounted for. Connecticut voids more candidacies through expired permits and missed sittings than through audiometry, and both of those failures are visible a year in advance.
A study plan built on how this examination is actually put together
Build the plan in the order the risk presents itself. First, the performed audiometric examination — full runs on real people, masking decisions made and defended aloud, recording completed to a standard another practitioner could use, until the procedure is unhurried and complete. Second, the ear impression chain — inspection, block, material, removal, inspection again — rehearsed as one sequence, because its failures are omissions, and omissions are trained away only by repetition. Third, the written syllabus — the ILE’s professional knowledge, studied against the practice definition in section 20-396 so every principle is tied to the Connecticut work it authorizes. Fourth, Chapter 398 as scenarios — a consumer with drainage ninety days ago, a seventeen-year-old purchaser, a return on day twenty-nine, a deposit on an aid not yet available for inspection — because the chapter’s duties arrive in practice as situations, not as section numbers. Fifth, the calendar — sitting dates worked backward from the Temporary Permit’s expiry, forms and proofs filed early, the single permit renewal held in reserve rather than spent by drift. Woven through all of it: study peaks against a sitting the statute only guarantees twice a year, so the plan is built backward from a date, not forward from a mood.
The working method: turning the outline into a performance
Connecticut preparation fails most often as a modality problem: candidates study a three-format examination as if it were a reading test. The working method that answers it has four parts. Perform weekly, and narrate. Full audiometric examinations and complete impression sequences, done on real people, with every step and every judgment spoken as it happens — the oral part of this examination rewards the candidate who has been explaining their hands all along. An error log keyed to the parts. Every missed written item, every masking hesitation, every skipped inspection step, and every misremembered duty of Chapter 398 filed under its part — written, audiometric, impression, law — so that after a month the log, not confidence, assigns the remaining study. Law learned as the sale it governs. Each duty rehearsed inside the transaction it controls: the receipt written out in full, the trial disclosure placed where the statute places it, the referral advice given in words a consumer understands. Calendar dry runs. Before each sitting, walk its checklist cold: application filed, fee paid, proofs accepted, permit current, sitting date confirmed — because in a twice-yearly system, an administrative failure is a six-month failure.
The errors this examination is built to catch
The Connecticut examination catches a recognizable set. Preparing only for the written paper meets a candidacy two-thirds of which is spoken and performed. A partial audiometric routine — screening habits, abbreviated procedure, masking by routine rather than by indication — meets a section whose stated standard is a full audiometric examination. Skipping the inspection in the impression sequence repeats, inside the examination, the exact omission section 20-403 exists to prevent in practice. Treating the Temporary Permit as open-ended spends its one renewal by drift and then discovers the permit, and the supervised practice it authorizes, has expired before the sitting. Confusing the audiologist’s position with the specialist’s — assuming an exemption, a scope, or a qualification that belongs to a different license — misreads the first section of the chapter. And quoting a passing percentage from unofficial material aims the whole preparation at a number Connecticut has not published.
The credential in one view
The Connecticut Licensed Hearing Instrument Specialist license in one view is a definition with an examination wrapped around it. Section 20-396 defines a practice — measure hearing comprehensively, screen for the listed disorders, make impressions, select and adapt aids, instruct and counsel — and Chapter 398 then asks the candidate to prove that practice three ways: know it on paper, say it under questioning, and do it with their hands. Everything after the examination is the same definition operating as law: refer the warning conditions, sell on the statutory trial terms, write the statutory receipt, keep the statutory records. The candidate who studies the three parts 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 chapter explains why the whole practice is licensed in the first place.
After the sitting: the license and its clocks
Passing changes the candidate’s title, not the chapter’s grip. The license renews once every two years; the renewing specialist earns not less than sixteen hours of continuing education inside the preceding twenty-four months, in courses offered or approved by the International Hearing Society, the American Academy of Audiology, or the American Speech-Language-Hearing Association, attests to it on the Department’s form, and keeps the records for at least three years against a Department request — with the first renewal exempt from the education requirement, a medical waiver or extension available in individual cases, and eight hours of recent continuing education required to reinstate a license that has become void. The place-of-business duties run continuously: notify the Department of each place of business and of any change at least ten days in advance, post the license conspicuously where the work is done, and take duplicate licenses for additional offices, which the Commissioner issues without additional payment. The specialist who treats renewal education as part of the practice — the same approving bodies whose study guide prepared the written paper — meets the biennial clock as a formality rather than a deadline.
The consumer on the other side of the examination
One last connection is worth making explicit, because it explains the chapter’s shape better than any other. Every element Connecticut examines reappears, after licensure, as a protection for a named consumer. The full audiometric examination becomes the measurement on which a real person’s amplification is chosen. The ear impression becomes the earmold a real person wears daily. The section 20-403 referral duty becomes the moment a real person with a treatable medical condition is sent to a physician instead of sold an aid. The thirty-day trial, the itemized receipt, and the three-year record become that person’s ability to unwind a purchase, prove its terms, and be followed up. Even the supervision rules point the same way: section 20-404 makes a licensee’s failure to properly supervise a temporary permit holder a disciplinary ground, because the consumer served by a trainee is entitled to the licensee’s competence, not just the trainee’s effort. A candidate who internalizes that mapping studies differently — the performed sections are rehearsals of consumer encounters, the written paper is the knowledge those encounters consume, and the chapter is the promise the license makes to the person across the counter. Connecticut’s examination is demanding in exactly the places where a consumer, rather than a candidate, would pay for a weakness.
Frequently asked questions
Which Connecticut sources govern this route?
Chapter 398 of the Connecticut General Statutes for the credential, the examination, the permit, renewal, and the consumer-protection duties; and the Department of Public Health’s licensing packet for how the written and oral/practical parts are identified and administered. Read both — the statute gives the standard, the packet gives the sitting.
Why does Connecticut give its own examination instead of simply adopting a national paper?
As published, it does both in part: the statute requires an examination “given by the department,” and the Department’s packet identifies the written part of that examination as the IHS International Licensing Examination, while the oral/practical parts — a full audiometric examination and an ear impression — are the Department’s performed sections. The candidacy is Connecticut’s even where one component is a national paper.
Is there a published Connecticut passing score I should aim at?
No numerical passing score was published on the Connecticut sources verified for this guide, and none is printed here. Section 20-398 requires satisfactory passage of the written, oral, and practical examination; prepare each part to working standard rather than to a rumored number.
How does the Temporary Permit’s clock actually work?
One year of supervised fitting or sale — no selection of hearing aids — from issuance. If the licensing examination has not been passed within that year, the permit may be renewed once for $60. After that, the statute provides no further renewal, so the examination must be passed inside the permit’s life or the supervised route pauses with it.
What should I do after an unsuccessful attempt?
Rebuild against the part that failed and protect the calendar: written failures call for syllabus work against the IHS study guide the packet names; performed-section failures call for supervised live rehearsal, not more reading; and in every case the next sitting is one of the at-least-twice-yearly sittings, applied for on the Department’s forms, inside the Temporary Permit’s remaining life if you hold one.
Does the examination test diagnosis of ear disease?
No. The credential is a fitting-and-selling license for a person other than an audiologist or physician. Recognizing the section 20-403 warning conditions and advising consultation with a physician or otolaryngologist is part of the specialist’s examined duty; diagnosing the condition is not.
Can an out-of-state licensee really skip the Connecticut examination?
Only on the Department’s determination, under section 20-399: the other state or jurisdiction must have equivalent or higher requirements and an equivalent or stricter qualifying program, the applicant’s license must be current, unsuspended, and unrevoked, and no disciplinary action may be pending and no complaint unresolved. It is a departmental judgment on a record, not an automatic reciprocity.
How is the apprenticeship — the Temporary Permit period — supervised?
Directly: the permit holder works under the direct supervision and training of a person holding a valid hearing instrument specialist license or a Connecticut audiology license, or while enrolled in a Department-approved course of study. Failure to properly supervise a temporary permit holder is itself a ground for discipline against the supervisor’s license under section 20-404.
What continuing education counts at renewal?
Courses offered or approved by the International Hearing Society, the American Academy of Audiology, or the American Speech-Language-Hearing Association, or successor organizations approved by the Commissioner — not less than sixteen hours inside the preceding twenty-four months, with records retained for at least three years.
Is PassProfessor affiliated with the Department of Public Health or IHS?
No. PassProfessor is an independent preparation provider. The Department alone licenses and gives the examination; IHS developed the written examination the Department’s packet identifies.
