CABT Exam Overview
The Certified Associate in Biomedical Technology (CABT) exam is an entry-level certification aimed at individuals who are beginning their careers in the biomedical equipment field. It’s designed to validate the basic knowledge and skills required for biomedical equipment technicians (BMETs) who maintain and repair medical devices and equipment. This certification is offered by the Association for the Advancement of Medical Instrumentation (AAMI) in collaboration with the Healthcare Technology Certification Commission (HTCC).
Who Typically Obtains the Certification?
The CABT certification is ideal for:• Entry-level biomedical technicians or individuals who are new to the field of healthcare technology management (HTM). • Recent graduates of biomedical technology programs or military personnel transitioning to civilian HTM roles. • Individuals seeking to gain foundational knowledge of medical equipment technology and begin their career in the healthcare technology sector.
CABT Exam Format and Breakdown• Duration: The CABT exam lasts 2 hours. • Number of Questions: The exam consists of 100 multiple-choice questions. • Scoring Requirements: You must achieve a passing score, typically around 70% or higher. However, this may vary slightly as the scoring standard is adjusted based on exam difficulty.
Subject Matter Breakdown
The CABT exam covers the following primary areas of biomedical technology:1. Medical Equipment Function (35%–40%): • Basic knowledge of how medical devices and systems operate, including common devices like defibrillators, patient monitors, infusion pumps, and ventilators. 2. Healthcare Technology Safety (25%–30%): • General principles of electrical safety, fire safety, mechanical hazards, and infection control in the maintenance of medical equipment. 3. Medical Equipment Maintenance (20%–25%): • Routine preventive and corrective maintenance tasks, calibration procedures, and performance checks for biomedical equipment. 4. Basic Troubleshooting and Repair (10%–15%): • Understanding of troubleshooting processes, diagnostic tools, and basic repair techniques for biomedical equipment. 5. Professionalism and Ethics (5%–10%): • Focuses on ethical conduct, professional behavior, and effective communication in a healthcare environment.
