- BIET is an ETA International credential covering 18 domains, from Anatomy to Linear Accelerators.
- Passing requires 75% on a written exam only - there is no hands-on component.
- The standalone exam costs $80; remote proctoring through ExamRoom.AI adds $16.
- Certification lasts four years and requires 40 CE hours or employer verification, plus $100 total.
What This Cheat Sheet Covers
This page is a compressed, no-fluff reference for candidates who already know the fundamentals of the Biomedical Imaging Equipment Technician (BIET) certification from ETA International and just need the numbers, domains, and mechanics reinforced before test day. It is not a substitute for structured preparation - for that, pair this cheat sheet with the full BIET Study Guide 2026: How to Pass on Your First Attempt and run practice questions on our BIET practice test platform to see how these facts show up in actual exam-style items.
Everything below traces back to ETA's own published materials on the BIET pathway, competency outline, and certification maintenance policy - no invented percentages, no borrowed facts from other credentials that happen to share the "BIET" acronym.

Standalone vs. Journeyman Pathway
BIET candidates choose between two structurally different routes, and mixing them up is one of the most common planning mistakes.
Standalone BIET
No foundational electronics certification is required to sit for the standalone BIET exam. This makes it the faster entry point for candidates who already work with imaging equipment but haven't completed prior ETA electronics credentials.
- Eligible with no prerequisite certification
- Same $80 exam fee, 75% passing score, 18-domain content outline
- Can later be upgraded once CETa is earned
Journeyman CET Specialty (BIET)
The Journeyman pathway treats BIET as a specialty layered on top of core electronics knowledge. ETA accepts either CETa or all five Electronics Modules (EM1-EM5) as the foundation, and recommends candidates have at least two years of relevant experience before attempting this route.
- Requires CETa OR complete EM1-EM5 modules
- Two years of experience recommended
- Positions BIET within a broader Journeyman credential structure
Already hold a maintained standalone BIET? You can upgrade it after earning CETa, provided you have at least two years of combined training and experience, for a $55 upgrade fee. For a deeper look at how these prerequisites interact, read BIET Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The 18 Domains, Condensed
The competency outline currently linked by ETA carries a 2019 copyright and lists 18 categories. Question distribution isn't publicly broken into weighted percentages, so treat every domain as fair game rather than assuming a few "count more." A full domain-by-domain walkthrough lives in BIET Exam Domains 2026: Complete Guide to All 18 Content Areas; here's the condensed version.
Foundational Knowledge Domains
These set up everything else on the exam and are easy to underrate because they feel "non-technical."
- Anatomy - structures and systems visualized by imaging modalities
- Medical Terminology - root words, prefixes, and abbreviations used across service records and clinical requests
- Computer - general computing concepts underlying modern imaging workstations
Safety & Infrastructure Domains
Safety-related domains reward memorization of specific standards and procedures rather than intuition.
- Electro/Mechanical Safety
- Building Wiring
- Radiation Safety
- Radiation Physics
- Codes and Regulations
Modality-Specific Domains
This cluster is the technical core of the BIET outline and where candidates need equipment-level familiarity, not just textbook definitions.
- Picture Archive Communication System (PACS)
- Diagnostic Ultrasound (Sonography) Equipment
- Basic Radiographic Equipment
- Film Processing - still an active category despite the shift toward digital imaging
- Magnetic Resonance Imaging
- Computed Tomography
- Nuclear Medicine
- Linear Accelerators
Applied Skills Domains
These tie the technical domains together into practical service scenarios.
- Test Equipment - meters, oscilloscopes, and diagnostic tools used during service calls
- Troubleshooting - systematic fault-finding logic applied across imaging modalities
Key Takeaway
Don't skip Film Processing because your facility is fully digital - it remains a named domain in the current outline, and questions can still test it.
Exam-Day Mechanics
Knowing the content is half the job; knowing exactly how the exam is delivered removes avoidable surprises.
- In-person testing: delivered via Trapeza or paper/pencil, administered by an ETA Certification Administrator.
- Remote testing: delivered through ExamRoom.AI, registered through ETA, adds US$16, runs as a two-hour exam session.
- What to bring: valid photo ID is required at every test site.
- What's allowed: scratch paper and a non-programmable scientific calculator. Used scratch paper must be handed back before you leave.
- If you don't pass: one free retake is available within one year of your first attempt - but if you retake remotely, the proctoring fee is payable again.
Scheduling logistics - where sites are located and how testing windows work - are covered separately in BIET Exam Dates 2026: Testing Windows, Deadlines & Scheduling. And if you're still calibrating how tough a 75% passing bar actually feels in practice, BIET Passing Score 2026: Exactly What You Need to Pass breaks that down question by question.
Maintenance & Renewal Snapshot
A four-year certification term means renewal planning starts the moment you pass, not three years later.
| Requirement | Detail |
|---|---|
| Certification term | 4 years |
| Continuing education | 10 related CE hours per year (40 total over 4 years) |
| Alternative to CE hours | Supervisor-completed employer verification |
| Maintenance fee | US$25 per year (US$100 over 4 years) |
| Paperwork | Maintenance form submitted, ideally annually per ETA's recommendation |
ETA explicitly recommends annual submission rather than waiting until the four-year mark to reconcile everything at once - a small habit that avoids scrambling for four years of documentation in one sitting.
A One-Week Domain Sprint
If your exam date is close and you need a compressed final review, structure your last week around domain clusters rather than random review. This isn't a generic study calendar - it's built directly around the BIET outline's groupings described above.
Foundational + Safety Cluster
- Anatomy, Medical Terminology, Computer basics
- Electro/Mechanical Safety, Radiation Safety, Radiation Physics, Codes and Regulations
Imaging Modality Cluster
- Basic Radiographic Equipment, Film Processing, Computed Tomography, MRI
- Diagnostic Ultrasound (Sonography) Equipment, Nuclear Medicine, Linear Accelerators
Systems & Applied Skills
- PACS, Building Wiring, Test Equipment, Troubleshooting
Full Simulation + Weak-Spot Repair
- Timed full-length practice run on the BIET practice test platform
- Re-review any domain scoring below your target 75%
- Confirm exam-day logistics: photo ID, calculator, test-center format
If a week feels too tight for your baseline knowledge, back this schedule up against the longer-format plan in the BIET Study Guide 2026 and start earlier.
Frequently Asked Questions
No. BIET certification is assessed entirely through a written exam - there is no hands-on examination component.
No. The standalone BIET pathway does not require a foundational electronics certification. That requirement only applies to the Journeyman CET specialty route, which accepts CETa or all five Electronics Modules (EM1-EM5).
You get one free retake within one year of your first session. Note that if you test remotely, the ExamRoom.AI proctoring fee is payable again for the retake.
The certification term is four years. Maintenance requires 10 related continuing-education hours per year (40 total over four years), or supervisor-completed employer verification, plus US$25 per year (US$100 over four years), submitted via the maintenance form - ideally annually as ETA recommends.
Yes. A maintained standalone BIET can be upgraded after you earn CETa, provided you have at least two years of combined training and experience, for a US$55 upgrade fee.
