BIET Certification

What the BIET Certification Actually Covers

The Biomedical Imaging Equipment Technician (BIET) certification is a credential administered by ETA International for technicians who service, calibrate, and troubleshoot diagnostic and therapeutic imaging systems in clinical environments. It is not a general electronics badge - it is purpose-built around the equipment found in radiology, ultrasound, MRI, CT, and nuclear medicine departments, as well as the safety codes and networking systems those departments run on.

If you're still sorting out exactly what this credential is before committing to it, our companion pieces What Is BIET? and What Is BIET Certification? break down the basics in plain language, while BIET Meaning and What Does BIET Stand For? clarify the terminology so you're not confusing this credential with unrelated acronyms that happen to share the same letters.

Standalone vs. Journeyman CET Pathway

ETA International offers two ways into BIET, and choosing the right one depends on your existing electronics background.

• Standalone BIET: No foundational electronics certification is required. Candidates can sit for the BIET exam directly, making this the faster route for imaging-focused technicians who already have on-the-job exposure to the equipment but haven't completed general electronics coursework.
• Journeyman CET specialty: This pathway requires either the CETa credential or all five Electronics Modules (EM1 through EM5). ETA recommends candidates have at least two years of relevant experience before pursuing this route.

There's also an upgrade path: a maintained standalone BIET can be converted to the Journeyman-level credential after earning CETa, provided the candidate has at least two years of combined training and experience, plus a $55 upgrade fee. For a full breakdown of prerequisites and which path fits your situation, see BIET Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Exam Format, Fees, and Scoring

The BIET exam is a written knowledge exam - there is no hands-on/practical examination component. Candidates answer questions drawn from the competency outline's 18 categories, and a score of 75% or higher is required to pass.

• Exam fee: US$80
• Passing score: 75%
• Format: Written/computer-based; no practical skills demonstration
• Time allotted (remote): Two hours

Because there's no bench-test component, your entire preparation should be aimed at the written content - recognizing circuits, safety standards, waveforms, and terminology rather than performing physical repairs during the test itself.

The 18 BIET Content Categories

The competency outline currently linked by ETA carries a 2019 copyright and organizes exam content into 18 categories. Each one represents a real slice of what imaging technicians encounter in the field - from patient anatomy terminology to building-level electrical infrastructure.

The remaining categories - Computer, Electro/Mechanical Safety, PACS, Diagnostic Ultrasound, Building Wiring, Basic Radiographic Equipment, Test Equipment, Codes and Regulations, and Troubleshooting - round out a scope that touches nearly every technical system in an imaging department. A full walkthrough of each of the 18 areas, with study emphasis for each, is available in BIET Exam Domains 2026: Complete Guide to All 18 Content Areas.

Registration, Testing Sites, and Remote Proctoring

Candidates have two main ways to sit for the BIET exam:

• In-person testing: Conducted using the Trapeza testing platform or paper/pencil format, administered by an ETA Certification Administrator at an approved test site.
• Remote testing: Delivered through ExamRoom.AI. This requires registering through ETA in advance and adds a $16 fee on top of the standard exam cost for the two-hour session.

On exam day, a valid photo ID is required. Scratch paper and a non-programmable scientific calculator are permitted - but any used scratch paper must be returned to the proctor at the end of the session, so don't count on taking notes home.

Retakes and What Happens If You Don't Pass

If your first attempt at the 75% passing threshold falls short, ETA International provides one free exam retake within one year of the original test date. That said, "free" applies to the base exam fee - if you retest via remote proctoring, the ExamRoom.AI fee is still payable since it's a separate service charge tied to the proctoring session, not the certification exam itself.

This retake policy is one reason a structured first attempt matters: you get a safety net, but not an unlimited one, and proctoring costs still apply.

Maintaining Your Certification for Four Years

A BIET certification is valid for four years from the date earned. To keep it active, ETA International requires:

• Submission of the maintenance form
• 10 continuing-education hours per year (40 total across the four-year term), or supervisor-completed employer verification in lieu of formal CE hours
• $25 per year, or $100 total across the four-year term

ETA recommends submitting maintenance documentation annually rather than waiting until the end of the term - this avoids a last-minute scramble to compile four years of CE records at once. Missing this cadence is a common, avoidable way certified technicians let their credential lapse.

Who Hires BIET-Certified Technicians

Employers seeking BIET-credentialed technicians are typically hospitals, imaging centers, third-party equipment service organizations, and OEM field service teams that maintain radiographic, ultrasound, MRI, CT, and nuclear medicine equipment. Because the competency outline blends clinical knowledge (anatomy, medical terminology) with hands-on technical domains (test equipment, troubleshooting, building wiring), the certification signals that a technician can move between the clinical floor and the equipment room without needing extensive hand-holding.

Building a Domain-Aware Study Plan

Because the BIET spans 18 distinct categories rather than three or four broad topics, an effective study plan is less about generic technique and more about sequencing your review to match where your knowledge gaps actually are - imaging physics, legacy film processing, or networking (PACS), for example.

Spacing your review sessions and revisiting weak domains rather than cramming a single pass through the outline tends to serve candidates better on an exam this broad. Once you've worked through the outline, running full-length practice sessions on our BIET practice test platform is one of the most direct ways to see how your recall holds up under exam-style questions across all 18 categories.
