ExploreAbout this exam
The Board Certified Hearing Instrument Specialist (BC-HIS) credential is a professional certification for hearing instrument specialists - the practitioners who evaluate hearing, select and fit amplification, and provide ongoing care to patients with hearing loss. It is typically pursued by specialists who already hold state licensure or are completing supervised clinical training, and it signals to employers and the public that the holder has met a national standard of knowledge beyond entry-level licensing. The exam is multiple choice and spans six content areas: basic sciences and acoustics, anatomy and physiology of the auditory system, disorders of hearing and audiologic assessment, hearing instrument technology and electroacoustics, fitting and verification with follow-up care, and professional, ethical, and regulatory practice. Questions test applied judgment as much as recall - expect real-world scenarios involving audiograms, real-ear measurement, troubleshooting, and patient counseling. Strong preparation combines a structured review of each domain with hands-on practice in fitting software, probe-microphone measurement, and case interpretation. Candidates should confirm current exam logistics, including scheduling, fees, and scoring, directly with the certifying organization, since those details change and are published on its official website.

What you'll study
About BC-HIS preparation
What is the BC-HIS exam format?
It is a multiple-choice examination delivered in a single sitting and organized around the six content domains described above. Questions are largely applied rather than purely definitional, so many present a short clinical scenario and ask for the best next step, interpretation, or recommendation. Confirm the current delivery method and any accommodations with the certifying organization.
How long is the exam, and how many questions are there?
The certifying organization publishes the current question count and time limit, and those figures are revised periodically, so check its official website for the version that applies to your test date. Do not plan your pacing around numbers from an older handbook or a forum post. Before test day, confirm the appointment length and any scheduled breaks.
What score do I need to pass, and what is the pass rate?
Passing standards and reported pass rates are set and published by the certifying body, not by preparatory resources. Because these figures are updated and can vary by testing cycle, verify them directly with the organization rather than relying on secondhand numbers. Focus your preparation on broad domain coverage instead of targeting a specific cut score.
How difficult is the exam?
Candidates with solid clinical experience generally find the fitting, verification, and assessment domains manageable, while acoustics and electroacoustics trip up those who have relied on software defaults. The exam rewards people who understand why a setting works, not just which button to press. Expect scenario questions that require you to reason through a case rather than recall a single fact.
Can I retake the exam if I do not pass?
Retake policies, waiting periods, and any additional fees are set by the certifying organization and can change. Check its official website or candidate handbook for the current rules before you sit for the exam, so you know your options in advance. Many candidates who retake do so after a focused review of the domain where they scored weakest.
In what order should I study the six domains?
Build the foundation first: acoustics, then auditory anatomy and physiology, then disorders and assessment. Technology and electroacoustics follow naturally once acoustics is solid, and fitting and verification sit on top of all of it. Professional and regulatory practice is efficient to review last as a concentrated block, though do not skip it - it carries real weight.
What are the most common reasons candidates fail?
The usual culprits are shallow acoustics knowledge, weak real-ear measurement reasoning, and an inability to interpret audiometric results in context. Another frequent problem is over-relying on memorized fitting rules instead of understanding the underlying rationale. Candidates who only review product features and skip physiology and ethics often lose easy points across multiple domains.
How much hands-on experience do I need before testing?
There is no single answer, but candidates who have performed real fittings, taken ear impressions, run probe-microphone measurements, and handled follow-up visits arrive far better prepared than those with only classroom exposure. If your experience is narrow, seek supervised practice in the areas you have not encountered, especially troubleshooting and verification.
