The Certified Biomedical Equipment Technician (CBET) program is provided by the Association for the Advancement of Medical Instrumentation (AAMI). It is a program meant for individuals who examine, repair, trouble shoot, and install biomedical devices utilized in hospitals and health facilities.
The CBET test covers such areas as healthcare technologies, electronics, safety of patients and facilities, anatomy and physiology, troubleshooting, and information technology in health care. Candidates need to check out the current AAMI certification standards before application.

Who Is Eligible for the CBET Exam?
CBET candidates must meet one of AAMI’s eligibility routes before sitting for the exam. These routes are based on education, military training, electronics training, or full-time biomedical equipment technology experience.
| Eligibility Route | Requirement |
|---|---|
| BMET associate degree | Associate degree in biomedical equipment technology plus two years of full-time BMET work experience |
| Military BMET training | Completion of a U.S. military BMET program plus two years of full-time BMET work experience |
| Electronics associate degree | Associate degree in electronics technology plus three years of full-time BMET work experience |
| Work experience only | Four years of full-time BMET work experience |
Candidates should confirm the current eligibility requirements with AAMI before applying, especially if their experience, education, or training does not fit neatly into one of the standard routes.
What Is Covered on the CBET Exam?
The CBET exam is divided into six major content areas. The largest areas are Healthcare Technology and Function and Healthcare Technology Problem Solving.
| Content Area | Percent of Exam | Main Topics |
|---|---|---|
| Anatomy and Physiology | 12% | Body systems, organs, blood, medical terminology, and basic physiology used in biomedical equipment work |
| Public Safety in the Healthcare Facility | 14% | Employee, patient, and visitor safety; electrical, chemical, radiation, biological, and fire hazards; codes and standards |
| Fundamentals of Electricity and Electronics | 10% | Circuits, components, transducers, power distribution, calculations, conversions, storage systems, and electronics terminology |
| Healthcare Technology and Function | 25% | Monitoring equipment, portable devices, life-support systems, therapeutic equipment, laboratory equipment, diagnostic imaging, operating room equipment, test equipment, and related terminology |
| Healthcare Technology Problem Solving | 25% | Troubleshooting techniques, equipment failures, diagnostic processes, repair decisions, and problem-solving in healthcare technology environments |
| Healthcare Information Technology | 10% | Hardware, software, middleware, integration, test equipment, security, regulations, safety requirements, and terminology |
High-Value Study Areas
Healthcare Technology and Function and Healthcare Technology Problem Solving together make up half of the exam. These areas deserve heavy study time because they test both equipment knowledge and the ability to apply troubleshooting skills in real healthcare settings.
- Review common categories of biomedical equipment and their clinical purpose.
- Practice identifying likely causes of equipment malfunction.
- Study electrical safety, facility safety, and healthcare regulatory expectations.
- Review basic anatomy and physiology so equipment function makes clinical sense.
- Practice electronics calculations and terminology.
- Review healthcare IT concepts, including hardware, software, integration, and security.
How Do I Register for the CBET Exam?
Candidates apply through AAMI. The application process usually requires candidates to submit eligibility documentation and pay the required exam fee before the application deadline for a testing window.
Because fees, application deadlines, testing windows, and submission procedures can change, candidates should review the current AAMI instructions before applying.
What Should I Expect on Test Day?
The CBET exam is administered as a computer-based test. Candidates should follow the instructions in their exam confirmation notice and arrive early enough to complete check-in.
- Bring the identification required by your exam confirmation instructions.
- Make sure your name on your identification matches your registration information.
- Do not bring prohibited personal items into the testing room.
- Follow all instructions from testing center staff.
- Use only the materials and tools allowed by the testing program.
The exam may provide testing supplies such as scratch paper or an on-screen calculator, but candidates should confirm current test-day rules before their appointment.
How Is the CBET Exam Scored?
CBET questions are scored based on correct answers. Incorrect answers are not penalized, so candidates should answer every question.
The passing requirement is set by AAMI. Candidates should verify the current passing-score policy before testing, since score reporting and passing standards can change over time.
Can I Retake the CBET Exam?
Candidates who do not pass may be able to retake the exam according to AAMI’s retake policies. Retake rules, fees, and waiting periods can change, so candidates should review the current AAMI instructions before reapplying.
How Can I Prepare for the CBET Exam?
Start by reviewing the current CBET exam content outline. The content outline shows the major topics tested and helps you decide where to spend your study time.
Then prioritize the largest content areas. Healthcare Technology and Function and Healthcare Technology Problem Solving together account for a large portion of the exam, so weak performance there can have a major impact on your score.
Practice questions are useful because they help you apply biomedical equipment knowledge the way it may appear on the exam. After each practice session, review missed questions carefully so you understand the equipment concept, safety rule, electronics principle, troubleshooting process, or healthcare IT issue behind the correct answer.
