Quick Facts at a Glance
Board Certified Audiologist (BC-A) is the credential awarded upon passing the General Audiology Board Certification (GABC) examination, administered by the American Board of Audiology (ABA) under the American Academy of Audiology. The 2026 administration is the inaugural beta exam, which is a separate credential path from the legacy ABAC certification and from the entry-level Audiology Praxis exam. If you only have five minutes before your review session, this table is your anchor.

The Six GABC Domains
The GABC blueprint organizes content into six domains. According to the 2026 Candidate Handbook (Edition 1), the page 19 summary table lists these weights, which total 100%. Worth noting for transparency: the handbook's detailed table and the public web outline instead show 18% for Domain 1, an unresolved discrepancy between official sources - so treat Domain 1's exact weight as approximate until ABA clarifies it.
Domain 1: Physiologic Basis of Auditory Function and Hearing Disorders (15%)
Foundational science: anatomy and physiology of the peripheral and central auditory system, pathophysiology of hearing and balance disorders.
- Know cochlear mechanics and auditory pathway structures cold - this domain underpins everything else
Domain 2: Assessment of Patients with Auditory Disorders (20%)
The second-largest domain. Covers case history, behavioral and electrophysiologic test selection, and appropriate protocol choice across the lifespan.
- Expect scenario items asking you to choose the next best assessment step, not just define a test
Domain 3: Diagnosis of Patients with Auditory Disorders (16%)
Interpreting assessment results to arrive at a diagnosis, differentiating conductive, sensorineural, mixed, and central pathologies.
- Pattern recognition across audiograms and tympanometry results is tested heavily here
Domain 4: Treatment and Management of Patients with Auditory Disorders (35%)
By far the largest domain. Amplification, implantable devices, aural rehabilitation, counseling, and management planning all live here.
- More than a third of the scored items map to this single domain - prioritize it accordingly
Domain 5: Additional Considerations in Diagnostic and Interventional Audiologic Care (9%)
Cross-cutting issues that don't fit neatly into assessment, diagnosis, or treatment alone - special populations, tinnitus, and vestibular considerations often surface here.
- Small weight, but easy points if you don't skip it in review
Domain 6: Professional and Practice Management Issues (5%)
Ethics, scope of practice, documentation, billing basics, and professional responsibility.
- Lowest weight domain, but the ethics content overlaps with GABC's stated ethics requirements for candidates
2026 Dates, Fees & Registration Mechanics
Because 2026 is the first year GABC has run, the calendar is tighter and less forgiving than a mature, rolling-testing program. There is one application window, one registration window, and one eleven-day testing window - miss any of them and there's no quiet fallback date later in the year.
- Applications: July 1 - September 15, 2026. This is when you submit transcripts, license verification, and documented experience.
- Exam registration: August 4 - October 13, 2026. This is separate from the application and happens once your eligibility is confirmed.
- Testing window: November 6 - 16, 2026, delivered via Prolydian with Proctor360 live remote proctoring.
- Results: Expected within 12 weeks of your test date, since this is a beta administration requiring psychometric review of item performance.
The current version governing all of this is the 2026 GABC Candidate Handbook, Edition 1, which expires January 2027 - meaning a revised edition is likely before the next cycle. Full scheduling logistics, including how the windows interact with employer approval timelines, are covered in BC-A Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Submit your application in the first half of the July-September window. A beta cycle with a single testing window leaves no margin for a late document or a licensure verification delay.
Exam Day Format & Testing Conditions
The GABC beta is a four-hour, closed-book exam with 225 multiple-choice and multiple-response items. Of those, 150 are scored and 75 are unscored field-test items being evaluated for future use - you won't know which is which, so every item deserves full attention. Passing standards are set through a modified Angoff process, meaning the cut score reflects expert judgment about minimally competent performance on each item rather than a fixed percentage.
- No calculator is permitted or needed
- Remote testing requires a webcam, microphone, and a single monitor
- Breaks are not built in unless you have an approved accommodation
- Testing language is English only
Because this format differs meaningfully from a traditional in-person board exam, candidates coming from other credentialing backgrounds should not assume prior test-day experience transfers directly. A closer look at what makes this exam demanding - beyond just content - is in How Hard Is the BC-A Exam? Complete Difficulty Guide 2026, and the exact scoring mechanics are unpacked in BC-A Passing Score 2026: Exactly What You Need to Pass.
Eligibility Pathways Snapshot
GABC eligibility isn't a single checklist - it's a set of parallel requirements plus one of three experience pathways depending on your degree and existing credentials.
- A master's or doctoral degree in audiology from a regionally accredited institution
- An active audiology license, or applicable international authorization
- Current audiology-related employment
- Transcripts and documented experience on file
- Adherence to ABA's ethics requirements
On top of those baseline items, full-time, paid, licensed post-degree experience requirements vary by pathway:
| Applicant Background | Required Experience |
|---|---|
| Doctoral degree in audiology | 5 years post-degree experience |
| Currently holds ABAC certification | 3 years post-degree experience |
| Master's degree in audiology | 7 years post-degree experience |
Notice that current ABAC holders have the shortest path - a deliberate bridge for audiologists already certified under the legacy credential. If you're unsure which pathway applies to you, or how documentation should be assembled before the July application window opens, walk through BC-A Requirements 2026: Eligibility, Prerequisites & How to Qualify before you start collecting transcripts.
A Domain-Weighted Priority Plan
Generic study advice - spaced repetition, timed drills, active recall - only helps if it's pointed at the right targets. Here, the targets are the domain weights themselves. This is not a full study system; it's a compressed sequence built for someone who already has clinical experience and needs to allocate limited review weeks intelligently.
Domain 4: Treatment and Management (35%)
- Review amplification fitting logic, implantable device candidacy, and aural rehabilitation frameworks
- Drill scenario items that ask "what's the next management step," not just terminology
Domain 2: Assessment (20%)
- Rebuild fluency with behavioral and electrophysiologic protocol selection
- Practice choosing the correct test battery for a given case history
Domain 3: Diagnosis (16%)
- Pattern-match audiometric and immittance findings to underlying pathology
- Cross-reference against Domain 1 physiology so diagnoses make mechanistic sense
Domain 1: Physiologic Basis (15% per summary table)
- Shore up cochlear, retrocochlear, and central pathway anatomy
- Treat this as the connective tissue linking assessment to diagnosis
Domains 5 & 6: Additional Considerations (9%) and Practice Management (5%)
- Cover special-population and vestibular/tinnitus topics under Domain 5
- Finish with ethics, scope of practice, and documentation under Domain 6
- Run at least one full-length timed practice session simulating the 4-hour, 225-item format
For a more complete week-by-week methodology, including how to structure practice tests and review cycles around the Proctor360 remote proctoring experience, see the BC-A Study Guide 2026: How to Pass on Your First Attempt. You can also run timed, domain-tagged practice questions on the main practice test platform to see which of the six domains needs another pass before your registration window closes.
After You Pass: Cycle & Maintenance
Certification as a BC-A is valid for five years. Edition 1 of the handbook anticipates a continuing-education requirement of 20 hours per year, totaling 100 hours across the five-year cycle, alongside ongoing ethics, licensure, and fee obligations. However, the detailed maintenance requirements - reporting mechanics, acceptable CE categories, and renewal fee structure - are scheduled for publication on October 1, 2026, so treat the CE figures as the current anticipated framework rather than finalized policy until that date.
Key Takeaway
Don't wait for the October 1, 2026 maintenance publication to start tracking CE hours. If you're already accruing audiology-related continuing education, log it now - it likely counts once the formal system launches.
Once certified, many candidates want to know whether the credential translates into hiring leverage or compensation differences. Because GABC is brand new for 2026, employer recognition is still forming; if you're weighing the investment of application fees, exam prep time, and CE obligations against career payoff, Is the BC-A Certification Worth It? Complete ROI Analysis 2026 and BC-A Salary Guide 2026: Complete Earnings Analysis lay out the considerations without guessing at numbers that aren't yet established.
