CET vs CRAT: Which EKG Certification Should You Get?

A side-by-side comparison of the CET (NHA) and CRAT (CCI) certifications — exam format, cost, content focus, and which one hiring managers prefer.

Why Certification Matters You do not need a certification to get hired as a telemetry monitor tech in most states. But you probably need one to get hired quickly, to earn more, and to stand out against other applicants. Most hospital job postings for monitor techs say "certification preferred" or "certification required within 6 months of hire." Showing up with a credential on day one signals that you already know the fundamentals and can hit the ground running during orientation. The two certifications that matter for telemetry monitoring are the CET from the National Healthcareer Association (NHA) and the CRAT from Cardiovascular Credentialing International (CCI). Both are nationally recognized. Both cover cardiac rhythm interpretation. But they are not identical. CET — Certified EKG Technician (NHA) The CET is the broader of the two credentials. It covers EKG acquisition (performing 12-lead EKGs) in addition to rhythm interpretation and monitoring. What the exam covers - Cardiac anatomy and physiology - EKG acquisition procedures (electrode placement, patient preparation, troubleshooting) - EKG interpretation (waveform components, intervals, rhythm identification) - Patient care and safety Exam format - 100 multiple-choice questions - 2-hour time limit - Passing score: approximately 390 out of 500 - Proctored at PSI testing centers or approved institutions Cost - Exam fee and study material costs vary by program — check the NHA website for current pricing - Renewal: every 2 years with continuing education credits Who it is best for The CET is a good fit if you want flexibility. It qualifies you for monitor tech positions and EKG technician roles where you would perform 12-lead EKGs at the bedside. If you are not sure whether you want to sit at a monitoring station or work as a mobile EKG tech, the CET covers both tracks. CRAT — Certified Rhythm Analysis Technician (CCI) The CRAT is laser-focused on cardiac rhythm monitoring. It does not cover EKG acquisition — it assumes you are sitting at a central station watching monitors, not at the bedside performing tests. What the exam covers - Cardiac anatomy and electrophysiology - Cardiac rhythm interpretation (identification, measurement, regularity assessment) - Monitoring procedures (lead systems, alarm management, documentation) - Patient safety and communication protocols Exam format - 85 scored questions plus 15 pretest questions (100 total) - 2-hour time limit - Passing score: scaled, determined by psychometric analysis - Proctored at Pearson VUE testing centers Cost - Exam and study material fees vary by program — check the CCI website for current pricing - Renewal: every 3 years with continuing education credits Who it is best for The CRAT is the most targeted credential for telemetry monitor technicians. Hospitals with dedicated monitoring stations often prefer or specifically request the CRAT because it validates exactly the skills the job requires — continuous rhythm observation, arrhythmia identification, and communication with nursing staff.
