This package supports candidates preparing for the written licensing examination used by state and provincial boards for hearing aid dispensing, currently the International Licensing Examination for Hearing Healthcare Professionals administered by the International Hearing Society. The practice format is scenario-based multiple choice with supporting knowledge checks across assessment, interpretation, device selection, fitting, follow-up, and safety and ethics. State and provincial licensing rules vary, so confirm the current examination, licensing requirements, fees, pass marks, and any practical or oral components with IHS and your own board. The material is subject to review if those authorities update their requirements. The written licensing exam is practice-based and scenario-driven. Use this package to rehearse assessment interpretation, device selection, verification, counseling, and safety and referral decisions; then confirm jurisdiction-specific rules with the issuing board. The 20 questions are supporting-knowledge practice, not a full exam simulation.
Know the credential and the task
Focus on entry-level, practice-based decisions rather than memorized slogans.
The written licensing examination is used by state and provincial boards as one part of the licensing process for hearing aid dispensing. The examination is designed to identify entry-level professionals whose knowledge and clinical judgment meet basic professional standards. That means questions commonly ask you to apply a rule to a patient scenario, not merely recall a definition.
The boards remain responsible for license eligibility, supervision requirements, practical or oral components, and state or provincial law. Confirm current requirements with the International Hearing Society and your own licensing board before you rely on any preparation plan. Use this guide to strengthen clinical reasoning and test familiarity, not as a substitute for hands-on training or your jurisdiction's rules.
How the written exam tests you
Train for application: interpret data, choose an action, and justify the next step.
The IHS study guide describes a 105-item multiple-choice examination scored on 80 items, with dichotomous scoring and some items that ask for more than one correct response. Administration details can change, so verify the current length, scoring, and item rules with IHS and your board. The important preparation point is the cognitive demand: the exam is practice-based and expects comprehension, application, analysis, and judgment.
This 20-question preview checks supporting knowledge. It is not a simulation of the licensing examination, not a prediction of your score, and not a replacement for the full body of knowledge. Read each stem for the actual question, eliminate options that violate safety or scope, and practice explaining why the remaining option is best.
Priority map: where to spend study time
Study the intersections where assessment, selection, fitting, and safety meet.
The published competency framework effective January 1, 2024 lists five domains with approximate weights: patient assessment 21%, interpretation and application of results 22%, device selection 18%, fitting and dispensing 20%, and continuing care 19%. Treat those percentages as planning aids after confirming the current blueprint with IHS and your board. Do not study each domain in isolation. High-yield questions often combine an audiogram with candidacy, a device style with earmold acoustics, or a follow-up complaint with verification and referral.
Build one-page decision maps for four recurring tasks: identifying type and degree of loss, deciding whether referral is needed, selecting a starting device and coupling, and choosing between verification and validation. Then rehearse short written rationales. If you can explain the why in two or three sentences, you are preparing for the exam's applied style.
Hearing science and assessment: read the pattern, not just the numbers
Use pure-tone averages, air-bone gaps, masking logic, and speech results together.
A three-frequency pure-tone average is the mean of air-conduction thresholds at 500, 1000, and 2000 Hz. Compare it with the bone-conduction average, but also inspect each frequency. Suppose air thresholds are 45, 50, and 55 dB HL and bone thresholds are 15, 20, and 25 dB HL. The air PTA is 50 dB HL, the bone PTA is 20 dB HL, and the 30 dB average air-bone gap points to a conductive component. If bone thresholds are also reduced and an air-bone gap remains, the pattern is mixed. If air and bone are equal and both are reduced, the pattern is sensorineural.
Masking, otoscopy, and speech testing are not side topics. If a left-ear response may be coming from the right ear, mask the non-test ear when indicated and recheck rather than recording a questionable threshold. Sudden unilateral loss, pain, drainage, dizziness, or a marked change from prior testing should trigger referral according to protocol. In speech testing, a high score that rolls over substantially at a higher presentation level should raise concern for retrocochlear involvement and warrant medical or audiological referral.
Selection and fitting: start with goals, then acoustics
Match the device and coupling to the loss, ear, lifestyle, and feedback risk, then verify.
Device selection begins with the case history and listening goals, not with a favorite style. A patient with near-normal low-frequency hearing and high-frequency loss may benefit from an open-fit receiver-in-canal approach because reduced occlusion and appropriate venting can preserve natural low-frequency sound. A patient with severe-to-profound loss and feedback risk may need a more occluding coupling. Manual dexterity, vision, cognitive support, and caregiver involvement also shape the choice.
Earmold acoustics are testable because they change the sound delivered to the eardrum. Increasing vent diameter generally reduces low-frequency gain and can reduce occlusion effects; reducing the vent generally increases low-frequency output and occlusion risk. Prescriptive targets are a starting point, not a guarantee. If real-ear measurement at 2000 Hz is 38 dB and the target is 30 dB, the immediate calculation is a 8 dB excess: reduce gain in that region, recheck, and confirm comfort. If the measured value were 24 dB against a 30 dB target, you would consider a 6 dB increase. Avoid global changes when the problem is frequency-specific.
Verification, counseling, follow-up, and safety
Separate objective verification from patient-reported validation and address safety first.
Verification asks whether the device is producing the intended acoustic output in the patient's ear. Real-ear measurement and speech mapping are common examples. Validation asks whether the fitting is helping the patient's daily communication and quality of life. A self-report questionnaire can support validation, while a real-ear measure supports verification. Neither replaces the other.
Counseling should set realistic expectations without promising perfect speech understanding, especially in noise. Explain that adjustment varies, schedule follow-up, and teach communication strategies. During troubleshooting, use a sequence: check the battery or charge, inspect the tubing and coupling for wax or moisture, perform a listening check, confirm the program, and then consider programming or repair. Infection control and scope-of-practice boundaries apply throughout. If a patient reports pain during an impression, stop, assess, and refer when indicated. Never force a procedure or represent a hearing aid as a cure.
Integrated practice task and self-check rubric
Use one case to rehearse the full chain from audiogram to follow-up.
Case: an adult reports gradual bilateral hearing difficulty and no red flags. Right air thresholds are 45, 50, and 55 dB HL at 500, 1000, and 2000 Hz; left air thresholds are 50, 55, and 60 dB HL; bone thresholds equal air thresholds. Word recognition is 84% right and 76% left at 80 dB HL. Tympanometry is normal. The patient wants a discreet device, is socially active, and sometimes struggles in restaurants.
Open-task practice: calculate each ear's three-frequency PTA, classify the loss, state whether an air-bone gap is present, and identify any information that would change your referral decision. Recommend a starting style and coupling, justify the choice using low-frequency gain needs and occlusion risk, and describe one verification method and one validation method. Write a counseling outline covering realistic restaurant listening, follow-up, and troubleshooting. Finally, document the plan in a short SOAP-style note.
Self-check rubric, scored 0 to 2 for each criterion: 0 means missing, 1 means partial, 2 means complete and defensible. Criterion 1: correct PTAs and classification. Criterion 2: device and coupling rationale tied to the audiogram and lifestyle. Criterion 3: appropriate verification and validation plan. Criterion 4: counseling with realistic expectations and follow-up. Criterion 5: safety, scope, and documentation. A strong answer earns 9 or 10 and can explain every point without relying on brand claims.
Common errors that cost points
Most errors come from skipping a step or confusing related concepts.
Common clinical errors include confusing dB HL with dB SPL, treating an air-bone gap as sensorineural loss, ignoring masking when crossover is possible, and selecting a device before reviewing the case history or red flags. Another frequent mistake is using a validation questionnaire as if it were objective verification, or changing all gain channels when only one frequency region is outside target.
Exam-taking errors include choosing the most familiar option rather than the safest next step, overlooking multiple-response wording, and ignoring scope-of-practice limits. If an option promises a cure, guarantees perfect hearing in noise, or skips referral for a red flag, it is usually wrong. If a state-law item appears, the best answer typically begins with verifying the current board rule rather than assuming that another jurisdiction's rule applies.
A practical study sequence
Use active recall, short scenarios, and spaced review rather than passive rereading.
Week 1: review acoustics, decibel scales, auditory anatomy, and audiogram symbols; practice PTA and air-bone-gap calculations. Week 2: work through masking logic, speech audiometry, otoscopy safety, and referral indicators. Week 3: study styles, coupling, venting, feedback risk, and candidacy. Week 4: rehearse prescriptive targets, real-ear verification, validation, and programming adjustments with short cases. Week 5: focus on counseling, follow-up troubleshooting, infection control, ethics, and scope. Week 6: complete integrated case write-ups such as the task above and review your errors.
For each study session, spend most of the time retrieving information: explain a concept aloud, calculate a PTA from a fresh audiogram, or write a two-minute action plan for a scenario. Then compare your answer with a checklist. Schedule review of weak topics rather than rereading strong topics. Confirm any jurisdiction-specific rule with the named issuing body, and use hands-on training with a qualified supervisor to connect the written material to practice.
