The Certified EKG Technician credential, known as CET, is NHA’s credential for electrocardiograph technicians who prepare patients and equipment, acquire EKG tracings, and recognize and report what those tracings show. The real examination is a closed-book, multiple-choice test of 120 administered questions in 2 hours. PassProfessor’s program holds 1,500 original practice questions built to the 2026 NHA CET test plan across its three domains, weighted the way the plan weights them, with an explanation for every question. The program is in the works at $49; enrollment opens through the notify list.
Which CET is this?
This CET is NHA’s Certified EKG Technician — the health care credential. The letters CET are used by more than one field, and candidates occasionally land on the wrong preparation entirely. If you are looking for an electronics technician credential, this is not it, and nothing on this page applies to that field. This program prepares candidates for the NHA Certified EKG Technician examination: the credential for the technician who works with patients, EKG equipment, and tracings in clinical settings. Every question in the bank, every domain weight on this page, and every explanation in the program belongs to that examination and no other.
That clarity matters for a practical reason. EKG preparation fails when it drifts — into general medical assisting content the test plan does not carry, into cardiology depth written for clinicians rather than technicians, or into another credential’s syllabus altogether. The bank here stays inside the role the 2026 NHA CET test plan describes: a technician who keeps patients safe, follows compliance requirements, coordinates care with the wider team, acquires clean tracings, and analyzes and interprets what the tracing shows well enough to recognize, report, and escalate appropriately.
What the program covers
1,500 original practice questions, each with an explanation. The bank is built and verified: 1,500 questions written for PassProfessor, and an explanation for every question — not a bare answer key. Each explanation teaches the reasoning the question tests: why the keyed answer is right, what finding or principle decides it, and what separates it from the closest alternatives. None of the questions is an actual NHA item, a recalled item, or another provider’s material; the bank is original preparation written from the test plan outward.
Built to the 2026 NHA CET test plan, at the plan’s own weights. The test plan organizes the examination into three domains, and the bank follows that organization exactly. Safety, Compliance, and Coordinated Patient Care carries 510 questions. EKG Acquisition carries 600 questions, the largest share, matching its place as the largest domain in the plan. EKG Analysis and Interpretation carries 390 questions. Practicing inside that weighting means your preparation time lands roughly where the plan itself puts the emphasis, instead of spreading evenly across ground the plan treats unevenly.
Practice organized by domain, so weak ground shows early. Because every question sits in one of the three test-plan domains, your results can be read domain by domain. A candidate strong in acquisition but thin in analysis can see that split in practice, while there is still time to repair it, rather than learning it from the examination itself. The study loop the program is built around — practice, read the explanation, drill the domain that cost you, practice again — only works when the bank is sorted the way the test plan is sorted. This one is.
A timed practice form plus domain drills — our design, stated plainly. The program is organized around a timed practice form of 100 questions in 120 minutes, together with three domain drills drawn from the bank, one for each test-plan domain. That form is a preparation design PassProfessor chose, to give candidates sustained timed practice alongside focused drilling; it is not a claim about how the real examination is administered. The real examination’s own recorded facts stand in their own table below.
Explanations that teach the technician’s reasoning. EKG work rewards pattern recognition backed by principle: knowing what a clean tracing requires, what an artifact looks like and where it comes from, what a measurement shows, and what a finding calls for next. The explanations are written to build that reasoning, question by question, so repeated practice compounds into judgment rather than memorized answers to questions you have already seen.

- The price is a PassProfessor price. The $49 above is what this program will cost when enrollment opens. It is not the NHA examination fee. This page states no examination fee figure, because NHA confirms the fee at scheduling and registration — check there for the current amount.
- The passing standard is a scaled score. NHA’s standard is a scaled score of 390 on a 200–500 scale. It is stated here exactly as a scaled score, never as a percentage, and no practice percentage converts into it. Where this program uses 70 as a practice benchmark, 70 is a practice benchmark only — a study target we set, not the examination’s standard.
- Our bank’s counts are ours; the real examination’s facts are its own. The 1,500 questions and the domain counts above describe PassProfessor’s practice bank, and the timed practice form described above is our preparation design. The real examination’s recorded facts are set out separately, in the table that follows.
The real exam at a glance
| The NHA CET examination | Recorded fact |
|---|---|
| Format | Multiple-choice, closed book |
| Questions | 120 administered — 100 scored plus 20 pretest |
| Time | 2 hours |
| Delivery | School-administered, at a PSI testing center, or by live remote proctoring |

Those are the examination’s facts as recorded for this program. The practice bank’s job is to teach and test the test plan’s content thoroughly against them — not to replicate the sitting itself.
How the practice maps to the test plan
| 2026 NHA CET test-plan domain | Share of the plan | Questions in this bank |
|---|---|---|
| Safety, Compliance, and Coordinated Patient Care | 34% | 510 |
| EKG Acquisition | 40% | 600 |
| EKG Analysis and Interpretation | 26% | 390 |
Safety, Compliance, and Coordinated Patient Care (34%). The domain that frames everything else: working safely around patients and equipment, meeting the compliance expectations that govern health care work, and coordinating with the care team so findings reach the right people. Preparation here is about habits and judgment — the questions test whether the technician’s first instincts in a scenario are the safe, compliant, well-communicated ones.
EKG Acquisition (40%). The largest domain, and the hands-on heart of the role: preparing the patient and the equipment, placing electrodes correctly, running the tracing, and troubleshooting what degrades it. Acquisition questions reward candidates who understand why each step matters, because a tracing is only interpretable when it was captured correctly in the first place.
EKG Analysis and Interpretation (26%). Reading what the tracing shows: measuring and evaluating the recording, recognizing patterns and abnormalities, and understanding what the technician reports and escalates. This domain builds on acquisition — analysis of a poorly acquired tracing is guesswork — which is why the bank’s order of weight puts acquisition first in size and why your study should treat the two as connected skills.
A note on the test plan’s transition. The weights above are the 2026 test plan’s: 34, 40, and 26. The prior test plan weighted the same three domains 32, 44, and 24. That earlier weighting is recorded here as a transition note only: no effective date for the 2026 plan is published in the record behind this page, and this page claims none. The bank is built to the 2026 weights, and because its questions are sorted purely by domain, the same bank serves candidates preparing under either weighting.
How to use it
- Join the notify list today. Enrollment is not open yet, and the notify list is how you hear the moment it is. While you wait, read the CET exam guide — it walks the three domains in depth and lays out how to organize your preparation.
- Start by surveying all three domains. Early practice should touch safety and compliance, acquisition, and analysis alike, so your first domain-by-domain picture of yourself is honest rather than flattering.
- Read every explanation, including for questions you answered correctly. A right answer reached by a wrong reason is a wrong answer waiting for a differently worded question. The explanations are where the bank teaches; the questions are where it tests.
- Drill the domain that costs you. Let your results, not your preferences, set the next block of study. Candidates naturally rehearse acquisition because it is concrete; the plan gives safety and compliance more than a third of its weight, and analysis more than a quarter.
- Return to mixed practice before you test. After focused drilling, mix the domains again the way the test plan holds them together, and sit the real examination when your practice is consistently strong across all three — not merely strong in the largest one.
Frequently asked questions
What is the NHA Certified EKG Technician credential? It is NHA’s credential for EKG technicians — the health care workers who prepare patients and equipment, acquire EKG tracings, and recognize and report what the tracings show. This program prepares candidates for that credential’s examination, built to the 2026 NHA CET test plan.
Is this the electronics CET? No. CET is used as an acronym in more than one field. This page, this guide, and this program concern only NHA’s Certified EKG Technician credential in health care. If you are pursuing an electronics technician credential, this program is not preparation for it.
How many practice questions does the program include, and how is the bank organized? 1,500 original practice questions, with an explanation for every question. The bank is built and file-verified, and it is organized by the three domains of the 2026 NHA CET test plan at the plan’s own weights: 510 questions in Safety, Compliance, and Coordinated Patient Care (34%), 600 in EKG Acquisition (40%), and 390 in EKG Analysis and Interpretation (26%) — so practice results can be read domain by domain and weak areas identified early.
Does the program include explanations? Yes — an explanation for every question, all 1,500 of them. The explanations teach the reasoning behind the keyed answer and what separates it from the closest alternatives, so practice builds judgment rather than familiarity with questions you have already seen.
What score do I need to pass the CET examination? A scaled score of 390 on a 200–500 scale. That standard is a scaled score, not a percentage, and it cannot be converted into one — treat any source that turns it into a percentage with caution. In this program, 70 is a practice benchmark only: a study target we set for readiness, not the examination’s passing standard. Prepare for strength with margin across all three test-plan domains.
Am I eligible to take the CET examination? There are two routes, and both also require a high school diploma or GED — or a diploma expected within 18 months under the provisional window extended Oct 1, 2026 — plus 10 EKGs performed on live individuals. Under the training route, you completed a training program within the last 5 years. Under the experience route, you have 1 year of supervised EKG experience in the last 3 years, or 2 years in the last 5. NHA’s own publications govern eligibility, so confirm your route there before you register.
What does the program cost? $49. That is the decided PassProfessor price for this program, charged when you enroll after enrollment opens. It is the price of the practice program only — not the NHA examination fee.
What does the NHA examination cost? This page states no figure for it, deliberately. NHA confirms the examination fee at scheduling and registration, and that is where you will see the current amount. The only price stated on this page is the $49 PassProfessor program price above.
Are these the actual NHA examination questions? No. Every question is original to PassProfessor, written from scratch to the 2026 NHA CET test plan. We never use actual NHA items, recalled items, or another provider’s material.
How is the practice organized, and does it match the real examination? The program is organized around a timed practice form of 100 questions in 120 minutes, plus three domain drills — one for each test-plan domain. That is our preparation design, chosen for sustained timed practice and focused drilling; we do not claim it matches the real examination’s administration. The real examination is a closed-book, multiple-choice test of 120 administered questions — 100 scored plus 20 pretest — in 2 hours, as the fact table above records.
When will enrollment open? The bank is built — 1,500 questions with an explanation for every question — and the program is in final preparation as part of the expanding PassProfessor catalog. Join the notify list on this page and we will email you when enrollment opens. We are not publishing a date we cannot keep.
