What Happens If You Fail the NHA CET Exam? Retake Rules and Waits

If you do not pass the National Healthcareer Association (NHA) Certified EKG Technician (CET) exam, you can retake it after a minimum 30 day wait. NHA allows 3 attempts with at least 30 days between each, and after a third non-passing attempt, and after each one after that, you must wait 1 year before testing again, per the NHA Candidate Handbook updated October 5, 2026. Every retake requires you to re-register and pay the full exam price. Passing is a scaled score of 390 or higher on a 200 to 500 scale. Your score report posts to your NHA account within 48 hours for exams taken at a PSI testing center or through live remote proctoring, and as a preliminary report immediately for exams taken at your school, and it rates each of the exam’s 3 content domains as Above, Near, or Below the passing standard. NHA’s 2025 pass rate report shows 70.45% of the 23,429 CET exams administered that year ended in a pass, as of November 2026.

NHA’s CET Retake Policy: 3 Attempts, 30 Day Waits

The Candidate Handbook states the rule in one place: if you do not pass on the first attempt, you may retake after a 30 day waiting period, you are allowed three attempts with at least 30 days between each, and each repeated failure after the third requires a wait of one year. NHA’s guidance for candidates who did not pass repeats the 30 day and 12 month waits and adds that you must pay for each retake. Neither document publishes a lifetime cap on attempts; the policy instead lengthens the wait sharply after the third unsuccessful sitting. The table below lays out the sequence, current as of November 2026.

What Your Score Report Shows

NHA posts a score report to your account after every attempt, pass or fail. It shows your scaled score, whether you passed, and diagnostic information for each major content area, using categories that match the test plan. The CET test plan, still the current one as of November 2026 and based on a 2017 job analysis, covers 100 scored items across three domains: Safety, Compliance, and Coordinated Patient Care (32 items), EKG Acquisition (44 items), and EKG Analysis and Interpretation (24 items). Each domain is rated Above, Near, or Below the passing standard. To open the report, log in, choose Results in the left menu, then select View Detailed Score Report.

Two cautions from the handbook matter when you plan a retake. First, each rating covers a range, so Above does not mean you mastered a domain and Near does not mean you were close in a precise sense. Second, the ratings account for item difficulty while your overall score does not, so the three ratings cannot be added up to predict the result. NHA also states that a retake is unlikely to use the same exam form, so your ratings on one attempt do not guarantee the same rating on the next.

Score Timing and Retakes by Delivery Mode

NHA documents three ways to sit for the CET, and the retake process differs slightly by mode. In every case you schedule the retake through your NHA account. For test day logistics, see our guide to what to bring to the CET exam.

• School administered: A preliminary score report is available immediately after the exam. Rescheduling must happen before the exam starts and is approved by your school or employer. The handbook warns that a preliminary report is not a final result.
• PSI testing center: The score report posts within 48 hours. To move an appointment without repaying, reschedule through your account at least 24 hours ahead and within 6 months of the original date.
• Live remote proctoring: The reporting window is also 48 hours, and the same 24 hour rescheduling rule applies. NHA assigns the remote proctoring provider when you register, and your internet service and computer must meet the remote proctor system’s requirements.

What Failing Costs

Each retake is billed at the full exam price, and NHA does not publish a discounted rate. NHA does not print the dollar amount on its public CET page or in the handbook, so check the NHA Shop before you reschedule. If you believe a result is wrong, the handbook allows a written hand rescoring request within 60 days of the exam date, and NHA may charge a fee for it; the amount is not published. Rescoring determinations are final. For the fee side, see our guide to how much the CET exam costs.

What to Do During the 30 Day Wait

NHA’s own advice is to spend considerable study time on the content areas rated Below or Near, and not to skip areas rated Above, since those ratings are ranges. Because EKG Acquisition carries 44 of the 100 scored items, a Below or Near rating there usually deserves the largest block of review: lead placement, machine settings, patient positioning, and recognizing and resolving artifacts. If Analysis and Interpretation was your weak domain, drill rate calculation, interval measurement, and rhythm recognition under timed conditions. If Safety, Compliance, and Coordinated Patient Care was the gap, review patient communication, vital signs, infection control, and scope of practice. A 30 day window is short, and the exam is 2 hours, so timed practice that matches the exam’s pace helps fix pacing as well as knowledge.
