NHA CET Exam Prep: 120 Questions, 390 Score, and the Fall 2027 Change

By the Castleport Test Prep Editorial Team · Last verified: August 17, 2026**

The NHA CET exam prep facts that control your plan are simple: the exam has 120 multiple-choice questions in 2 hours — 100 scored plus 20 unscored pretest items — and the passing standard is a scaled score of 390 out of 500. For exams before Fall 2027, the 100 scored items split 32 to Safety, Compliance, and Coordinated Patient Care; 44 to EKG Acquisition; and 24 to EKG Analysis and Interpretation. NHA has also published the final plan for exams after Fall 2027: the same 100 scored items, 20 pretest items, and 2-hour limit, with weights of 34 / 40 / 26.

Two things are worth 60 seconds of your attention before you buy a study guide.

Your test date. NHA now gives candidates both CET test plans. What it does not give is the exact calendar day that separates “before Fall 2027” from “after Fall 2027.” If your appointment falls during Fall 2027, check the candidate test-plan index and your NHA account before you buy version-specific material.

Your eligibility route. Every CET pathway still carries the program-specific requirement of 10 EKGs performed on live individuals. The approved pre-externship route can change when those are completed, but a course, voucher, simulator, or study guide does not create the evidence for you.

That's the honest bottom line. Everything below is the proof, the arithmetic, and the parts that will actually cost you money if you get them wrong.

Plain disclosure: Castleport Test Prep built the diagnostic, rhythm trainer, and study planner above. They are original Castleport tools based on NHA's published CET test plans; they are not official NHA products, and they do not predict passing. There is no paid Castleport CET product for sale.

Is this NHA CET exam prep page for you?

This page is for you if you're preparing for the NHA Certified EKG Technician exam, you want the domain weights and the passing standard from the documents that actually govern them, or you've just discovered the exam has a hands-on requirement nobody mentioned in your course.

This page is not for you if:

• You're looking for the Common Entrance Test, Central European Time, or a Certified Energy Technician credential. Different things entirely. Same three letters.
• You're taking the CPCT/A — the Patient Care Technician/Assistant exam. It contains some EKG content, but it's a different exam with a different blueprint, and NHA has split it into before-January-2027 and after-January-2027 versions. Go to NHA's CPCT/A page for that one.
• You want real or recalled exam questions. We don't publish those, and we'd steer you away from anyone who does — there's a reason for that further down, and it involves your credential getting revoked after you've already earned it.
• You need to register or check your fee. That lives inside your NHA account. We'll point you at it rather than stand in front of it.

The right prep path isn't the same for every candidate — it depends on the exam version you'll actually sit, your eligibility route, your test date, and how far you are from passing today. The official handbook and NHA set the requirements, not a checklist. Take the free Castleport CET diagnostic above and see exactly where you stand before you spend anything.

What's actually on the NHA CET exam before Fall 2027?

The before-Fall-2027 CET is 120 multiple-choice questions with a 2-hour limit: 100 scored items and 20 unscored pretest items you cannot identify. The 100 scored items are divided across three domains — Safety, Compliance, and Coordinated Patient Care (32 items), EKG Acquisition (44 items), and EKG Analysis and Interpretation (24 items).

Source: NHA CET Test Plan for Exams Before Fall 2027, based on a job analysis completed in 2017. Verified August 17, 2026.

Notice what surprises most people: the biggest domain isn't rhythm reading. Acquisition is. Getting the electrodes in the right place, keeping the tracing clean, and troubleshooting artifact is 44% of your score. Interpretation — the part everyone dreads — is 24%. If you've been avoiding this exam because you're shaky on arrhythmias, the blueprint is better news than you think.

You get 60 seconds per question. That's less generous than it sounds.

120 items in 120 minutes is exactly 60.0 seconds per item. For context, we ran the same arithmetic across the other medical-adjacent exams we cover:

So the CET ties for the most generous pace of the group. Here's the catch, and it comes straight out of the handbook: break time counts as testing time. If you step out, the clock keeps running. And if you test through Live Remote Proctoring — NHA's option to take the exam from home with a remote proctor watching through your webcam — no breaks are allowed at all. Not one. Plan a two-hour sit.

What do the 20 pretest questions mean for you?

Pretest items are questions NHA is trying out for future exams. They don't count toward your score, and you have no way to tell which ones they are. Treat every item as scored, make your best choice, and move on. One strange item cannot be allowed to eat four minutes and your confidence.

Why do two NHA documents show different pretest counts?

We found this while cross-reading NHA against itself, which is now standard practice on every NHA exam we cover.

• NHA's detailed CET test plan says 100 scored items + 20 pretest items.
• NHA's 2017 CET Practice Analysis Executive Summary — the study that produced that plan — says 100 scored items + 10 unscored pretest items.

Same study cycle. Two numbers. The current candidate-facing test plan settles it: 120 items total. The final after-Fall-2027 plan also says 100 scored plus 20 pretest. If you see 110 quoted somewhere, now you know where it came from.

→ Take the free 25-question CET diagnostic above. It is weighted 8 / 11 / 6 — exactly the 32% / 44% / 24% split, with no rounding. Instant score by domain, a written rationale on every item, no email.

Which NHA CET test plan applies to your test date?

NHA now publishes two final candidate test plans: 32 / 44 / 24 for exams before Fall 2027 and 34 / 40 / 26 for exams after Fall 2027. Both plans have 100 scored items, 20 pretest items, and a two-hour limit.

Use the NHA test-plan index, not a book cover, to decide which one applies. The index labels the plans “For Exams Before Fall 2027” and “For Exams After Fall 2027.” NHA does not publish the calendar day that resolves an appointment during Fall 2027, so that is the one date question this page will not invent.

The final CET version-change map

Sources: before-Fall-2027 CET test plan and after-Fall-2027 CET test plan. Statement counts are Castleport's hand-count of the final detailed plans. Verified August 17, 2026.

Broken down by domain:

That final table corrects a discrepancy inside NHA's own publication chain. The 2025–26 Job Task Analysis Executive Summary reports 36 tasks, including 16 for Acquisition. The final candidate test plan contains 32 tasks, including 12 for Acquisition. For study coverage, the final candidate test plan wins: it is the document NHA gives candidates and says is used to build the exam.

Our reading of the final plans, labelled as our editorial call: the revised outline names more candidate actions and fewer separate knowledge bullets. That is a prep signal to practice decisions in context, not proof that NHA changed the exam's item type. The final test plan itself says items may require recall, critical thinking, or both.

What should you do if your test is in Fall 2027?

Do not guess from the year printed on a prep book. Open NHA's test-plan index, check the plan shown for your appointment, and ask NHA if your account does not identify the version. The planner above lets you select either published version, but no Castleport tool can decide an effective date NHA has not supplied.

Is the CET passing score 390 or 78%?

It's 390. NHA scores its exams on a scaled range from 200 to 500 and sets the passing standard at a scaled score of 390. That is not the same as answering 78% of questions correctly, and NHA does not publish a universal raw-score conversion.

We're calling this out specifically because CET quick-facts pages publish the passing score as 78% — presumably by dividing 390 by 500. That arithmetic is fine. The conclusion isn't.

A scaled score is a raw score converted onto a common scale so different versions of the exam mean the same thing. NHA writes multiple forms, and some forms are harder than others. The scaling adjusts for that, so a 390 on one form represents the same passing standard as a 390 on another. The number of questions you need right to hit 390 is therefore not a fixed public number.

How the 390 got set is on the record: NHA used a modified Angoff method — a standard-setting process where a panel of experienced practitioners judges, item by item, whether a minimally qualified candidate would answer correctly. That panel met in 2018. Its judgments produced a raw cut score, which was transformed to 390 out of 500.

So the honest answer to “how many do I need right?” is: NHA does not publish it. Aim to be comfortably competent across all three domains rather than counting to a magic number.

How hard is the NHA CET exam, really?

About 7 in 10 exam administrations pass. NHA reported 71.08% in 2023, 69.66% in 2024, and 70.45% in 2025 — a 1.42-point range across the three current reports. Those are administration-level rates, not first-attempt rates and not an individual candidate's probability of passing.

Sources: NHA's 2023, 2024, and 2025 annual pass-rate reports. Failure counts are Castleport arithmetic from NHA's published volumes and percentages.

Three things worth knowing from that table.

One: the rate is stable. The three-year average is 70.40%, and the high-to-low spread is only 1.42 percentage points. That does not prove the exam has the same difficulty every year; it tells you the published outcome has stayed close to seven in ten.

Two: volume is rising. Administrations grew 39.5% from 2023 to 2025. The credential is getting more common. That is an argument for checking what employers in your market require, not an argument that the credential guarantees a job.

Three: the active-certification column is a year-end snapshot. It is not a retention study and cannot tell us why credentials were added, renewed, lapsed, reinstated, or removed. NHA publishes no causal explanation in these reports, so we will not turn the movement into one.

The number NHA expected — and what actually happened

This is the comparison we think matters most, and as far as we can tell nobody has run it.

When NHA set the 390 cut score in 2018, its CET National Standard Setting Study projected an expected pass rate of 74.8% at that cut. Put that next to the current published results:

Real exam administrations have come in about four and a half points below that 2018 projection across the three current annual reports.

Read that correctly. 74.8% was an expected impact estimate, not a measured national pass rate and not a target NHA promised to maintain. NHA's public documents do not identify the cause of the gap. It is calibration: the published outcome has been slightly lower than the standard-setting estimate, consistently enough that this is not an exam to wing.

Do you actually qualify to sit the CET?

For the standard candidate pathways, you need a high school diploma or recognized equivalent — or the provisional route — plus one qualifying training or work pathway and the CET-specific requirement of 10 EKGs on live individuals. NHA also publishes a separate instructor route, and instructors still must meet the program-specific CET requirement.

We're putting this before the study advice because it's the gate that actually stops people. Not the exam. The paperwork.

Do the 10 live EKGs apply to every CET pathway?

Yes. The Candidate Handbook says CET candidates must be able to provide evidence that they successfully performed at least 10 EKGs on live individuals. The instructor route also requires all program-specific requirements.

“Live individuals” is the operative phrase. The handbook does not say a simulator or mannequin can substitute. A course completion certificate and an exam voucher do not prove the 10 procedures.

There is one timing exception worth knowing: with an approved institutional agreement, a pre-externship candidate may sit after completing coursework and finish the program-specific requirement within that route's 90-day post-exam window. Miss the deadline — or have the institution fail to notify NHA in time — and NHA can void the passing score.

How many NHA CET eligibility routes are there?

NHA's public CET page summarizes training and work experience. The handbook gives standard candidates five training subroutes plus the work-experience route, and then publishes a separate route for eligible instructors.

Instructor candidates register individually, test at PSI or by Live Remote Proctoring, cannot test at their institution, and face separate proctor restrictions in the handbook.

If you finished a hospital-based program, came out of the military, are testing before an externship wraps, or teach in an NHA-associated institution, you may be eligible on a route the short marketing summary does not show. Read the handbook, not the summary.

When does the five-year training clock start?

Pathway 1 requires training completed within the past five years. That window is measured from your registration date — not your exam date, and not the date you started studying. If your program finished five years or more before you register, Pathway 1 is closed and you need another qualifying route.

Does NHA ask for your documents when you register?

Registration is attestation-based. You agree that you meet the requirements, and NHA reserves the right to request and audit the evidence. Do not turn “not requested during registration” into “not required.” Keep your program record or employer verification and your 10-EKG evidence with dates and a supervisor's name.

The consequences escalate depending on when a false or unsupported attestation is discovered: NHA can bar the exam without a refund, invalidate a score, or suspend or revoke a credential after it has been issued. This is the five-minute paperwork job that protects the credential you're about to spend months earning.

Can a high school student take the CET?

If you're scheduled to graduate from an accredited high school, GED program, or recognized equivalent within 12 months, you can test and receive a Provisional Certification if the other requirements are met.

• It expires 12 months after your exam date.
• It cannot be renewed or reinstated.
• Converting it to full certification requires proof of graduation and proof of the applicable training/work and CET program-specific requirements upon request.
• The full certification's expiration date remains based on the original testing date.

Does NHA certification replace state licensing rules?

No. NHA's handbook says its certification eligibility is separate from state law, regulation, or practice requirements. This page owns the national CET exam-prep decision; it does not claim one national credential authorizes every task in every state or workplace.

→ Check your eligibility with NHA directly. Eligibility decisions are NHA's to make, not ours: use NHA's CET page and the current Candidate Handbook.

Where should your first CET study hour go?

Before Fall 2027, put it in EKG Analysis and Interpretation — even though it's the smallest domain. It carries 24 of 100 scored items but 30 of the detailed plan's 91 task-and-knowledge statements: 1.25 statements per scored point versus 0.75 for Acquisition. After Fall 2027, Safety and Analysis are nearly tied on this same coverage-density measure, so your own misses should decide between them.

This is a Castleport coverage-density proxy, not an official NHA study-time instruction. We counted every task and domain-specific knowledge statement in both final detailed plans, then divided that coverage by scored items.

For the current before-Fall plan, Analysis asks you to cover 66.7% more statements per scored point than Acquisition. Acquisition is where the points are. Analysis is where the hours go.

For the after-Fall plan, the gap changes. Safety edges Analysis by this proxy, while Acquisition still gives the most scored points per named statement. The right move is not to memorize the ratios. It is to use them correctly: lock in Acquisition points, then put extra teaching time into whichever dense domain your practice exposes.

Which topics repeat across every current CET domain?

The before-Fall plan contains 64 domain knowledge lines, but they resolve to 47 distinct topics. Seventeen lines repeat a topic used elsewhere.

One outranks everything else: “Emergencies related to cardiac testing” appears seven times across all three domains. The final page then names three core knowledge areas that can appear in the context of any domain:

1. Basic anatomy and physiology of the heart
2. Emergencies related to cardiac testing
3. Cardiopulmonary resuscitation and basic life support

Practical translation: if you can recognize a patient going bad, know what to do about it, and explain the electrical anatomy underneath it, you're carrying knowledge that pays off across the exam. Start there. It's the highest-leverage hour on the current plan.

What strip-reading method should you use?

Don't try to recognize rhythms. Recognition fails under pressure. Run the same sequence every time, out loud if you're alone:

1. Rate — count the QRS complexes in six seconds and multiply by ten. This resolves to the nearest 10 and is useful for irregular rhythms.
2. Regularity — regular, regularly irregular, or irregularly irregular?
3. P waves — present? One per QRS? All the same shape?
4. PR interval — constant, lengthening, or unrelated to the QRS?
5. QRS width — under 0.12 seconds, or 0.12 seconds and up?

Five questions, same order, every strip. That sequence is what the rhythm trainer at the top of this page drills. It uses an EKG-style grid at 25 mm/s and 10 mm/mV. The tracings are simulated teaching strips, not patient data.

Which lead-placement landmarks should you lock down first?

Start with the two independent anchors:

• V1: fourth intercostal space, right sternal border
• V4: fifth intercostal space, midclavicular line

V2 mirrors V1 on the left. V3 sits between V2 and V4. V5 and V6 stay on the same horizontal level as V4, at the anterior and midaxillary lines. Starting V1 or V4 one space too high can shift the anterior set and change the tracing.

→ Build your CET study plan above. Select the exam version, enter your test date and the hours you can honestly give it, then let the planner split your time by official weight and your actual weakness. If you're retaking, it accepts the Below / Near / Above categories from your score report.

Are Quizlet and the big CET question banks enough?

Free flashcards and large question banks are genuinely useful for recall and volume, but question count alone does not prove the bank simulates the official domain mix. We checked Pocket Prep's current 650-question CET bank against the before-Fall-2027 plan, and the distribution is heavily tilted toward Analysis.

Let's be fair before we're critical. Popular CET banks have real strengths: hundreds of questions, rationales, timed modes, and progress tracking. Volume matters. We ship 25 diagnostic questions. Pocket Prep ships 650. On raw question count, it wins, and we're not going to pretend otherwise.

Source: Pocket Prep's CET question-bank details, checked August 17, 2026. Percentages and gaps are Castleport arithmetic.

The largest domain on the exam gets about 26% of the bank. The smallest gets about 47%.

In fairness — and this is where our own Study Load Map cuts both ways — over-weighting Analysis can be defensible as a teaching decision. It is dense on the current plan and needs repetition. But as exam simulation, a bank shaped like that does not reproduce 32 / 44 / 24.

Use it, but read it correctly: treat it as an Analysis-heavy tutor, not as proof that your mock mix matches the exam. Get separate Acquisition reps and use NHA's plan to check whether your total practice portfolio covers the whole blueprint.

What about “actual NHA CET exam questions”?

You will find listings advertising real or recalled questions. Skip them, and not for squeamish reasons. When you register, you attest that you will not memorize, reproduce, disclose, or solicit exam content. NHA can invalidate scores and suspend or revoke a credential after it has already been issued.

Our questions are original items written to the published test plan. Every diagnostic item shows its domain and task coordinate so you can inspect the mapping instead of taking our word for it.

Where does Castleport lose to a paid bank?

We don't offer a pass guarantee. Pocket Prep does. Its current remedy is three additional months of Premium Prep access at no charge if you do not pass; it is not a refund. If that promise helps you commit, read the eligibility terms and decide whether the remedy matters to you.

We'd rather put our promise somewhere we can keep it. Every official number on this page carries the document it came from and the date we checked it, and every Castleport tool here is free with no email. And to be straight with you: there is no Castleport CET book, question bank, course, price, access term, or buy button right now.

Want more volume than 25 questions? NHA's CET page says its official online prep includes three different practice tests with two attempts each. NHA also says buying its prep is not required and does not guarantee a passing score. Use the free diagnostic first to find the gap, then decide whether official simulation or a larger third-party bank solves the next problem.

What does the NHA CET exam actually cost?

NHA does not publish a current CET exam fee on a crawlable public page, so the only fee you should treat as yours is the number in your own NHA checkout. Current university storefronts price comparable voucher-included online programs from $2,295 to $2,695, and every retake requires the full exam price again.

Here's the admission, plainly. The Candidate Handbook does not print the exam fee. It sends you to the store. A specific figure repeated across prep sites is not a primary-source price.

The handbook's click path is: sign in to your NHA account, click Shop, choose your profession in the left column, then click the Certification Exam icon. Read your own checkout screen.

And here's the cost rule we will stand behind: you pay the full examination price again for every retake.

How much do voucher-included EKG courses cost right now?

We checked current storefronts that sell an online “Certified EKG Technician (Voucher Included)” program:

Prices checked August 17, 2026. That is a $400 spread — 17.4% above the lowest listing — before you decide whether any of these programs solves your hands-on requirement.

If you're shopping, the logo on the storefront is not the product. Compare the underlying course, the clinical plan, refund terms, and what the voucher actually covers.

Can you buy a course and still lack the 10 live EKGs?

Yes. This is the most expensive mistake available on this exam.

Stephen F. Austin's current course page says the provider cannot guarantee placement at a clinical site and that students are responsible for fulfilling clinical requirements. Put that next to NHA's 10-live-EKG rule: you can pay $2,299 for an asynchronous voucher-included course and still have to solve the live-procedure evidence yourself.

That does not automatically make every buyer ineligible to test. An approved pre-externship arrangement can allow completion after the exam within the handbook's deadline, and some programs may create acceptable structured practice or documentation. The decision question is still brutal and simple:

Before you enroll, ask in writing: “Who arranges the setting where I will perform and document the 10 live EKGs, and what happens if no placement is available?”

If the answer is vague, you've found out for free what other people find out after paying.

What does CET renewal cost after you pass?

NHA says two hours of qualifying instruction equals one CE credit in the handbook. Renewal and reinstatement prices are from NHA's current renewal page, verified August 17, 2026.

---

How do you register, and what does CET test day look like?

Create your own NHA account, apply for the CET, pay, then schedule through your institution, a PSI test center, or Live Remote Proctoring when available. Preliminary results can appear immediately at an institution; PSI and remote-proctored reports post within 48 hours.

The PSI scratch-paper rule changed June 1, 2026. Any prep page that still says PSI provides scratch paper is stale.

One more, because it's newer than most people's mental model of a testing center: NHA's prohibited-device list names AI glasses and earbuds alongside phones, tablets, watches, and translators. Leave the wearables outside the room.

If you need accommodations, file early. “Allow 30 days” means a request submitted three weeks before the appointment may not be resolved in time.

---

What happens if you fail the CET?

You wait at least 30 days, then retake. NHA allows three attempts with a minimum 30 days between them. After a third unsuccessful attempt, you wait one year. Every attempt requires re-registration at the full examination price.

Roughly 30% of 2025 CET exam administrations did not pass — about 6,900 attempts. You're in a large, unremarkable group. This is a checkpoint, not a verdict.

You also have two review routes: a hand rescore requested in writing within 60 days of the exam, and a formal appeal within 30 days. NHA may charge for a rescore, and the decisions are final.

How should you use a failed CET score report?

Your score report places each major content area into one of three bands: Above the passing standard, Near the passing standard, or Below the passing standard.

Two things about those bands:

• “Near” does not mean you were fine. NHA says Near does not indicate satisfactory performance in that content area.
• The bands cannot be added together. They account for item difficulty and do not average into a substitute overall score.

Because each CET domain has more than five questions, all three domains should receive a band. NHA uses “N/A” when a content area has five or fewer items; that threshold does not apply to any CET domain under either published plan.

Feed those three words into the planner at the top. Its retaker mode reallocates your available hours by the official domain weight and your Above / Near / Below result. It allocates time. It does not predict passing.

→ Turn your score report into a retake plan. Select “Retaking,” choose the correct exam version, enter the three bands, and get your hours split by what the report actually said.

Is the NHA CET certification worth getting?

The credential is NCCA-accredited, and NHA's own CET page says either 87% or 91% of employers require or encourage certification — both figures appear on the same page. The BLS publishes useful career context, but it does not publish pay for NHA CET holders as a separate group.

First, NHA's own contradiction. Near the top of its CET page, it says 87% of employers require or encourage certification. Farther down, attributed to its 2025 Industry Outlook, it says 91%. Same issuer, same page, same claim, four points apart. Use the claim as issuer-reported market context, not independent proof of what your employer requires.

Second, salary. The Bureau of Labor Statistics explicitly includes cardiographic or electrocardiogram technicians within Cardiovascular Technologists and Technicians, SOC 29-2031. That category also includes invasive/catheterization specialists and pulmonary-function technologists. It is broader than an entry-level EKG technician and much broader than holders of one named certification.

Those numbers are real. Calling $67,260 a “certified CET salary” is not. BLS does not isolate NHA CET holders, and the pooled category contains jobs with different education, procedures, and pay.

What the CET genuinely is: a nationally recognized, NCCA-accredited certification for EKG work that employers may require or prefer and that can fit an entry-level cardiovascular pathway. What it is not: a guarantee of employment, a state practice license, or proof that one salary number applies to you.

The decision comes down to your market. Check the job postings you can actually commute to. Count how many require or prefer NHA CET or another EKG credential, what experience they demand, and whether the pay difference covers your total training, exam, and renewal cost. That answer is more valuable than a national headline.

NHA CET exam prep FAQ

How many questions are on the NHA CET exam?

120 total — 100 scored items plus 20 unscored pretest items you cannot identify. Both published CET plans give a 2-hour limit.

What score do I need to pass the CET?

A scaled score of 390 on a 200–500 scale.

Is 390 the same as getting 78% correct?

No. NHA does not publish a universal raw-percent conversion, and the raw cut can differ by exam form.

What is the CET pass rate?

NHA reported 70.45% on 23,429 exam administrations in 2025. The published rate was 71.08% in 2023 and 69.66% in 2024.

How is the CET exam weighted before Fall 2027?

32% Safety, Compliance, and Coordinated Patient Care; 44% EKG Acquisition; 24% EKG Analysis and Interpretation.

How is the CET exam weighted after Fall 2027?

34% Safety and Compliance; 40% Acquisition; 26% Analysis and Interpretation. The total remains 100 scored items plus 20 pretest items in two hours.

What happens if my exam is during Fall 2027?

NHA's index labels one plan “before Fall 2027” and the other “after Fall 2027” but does not supply the exact calendar boundary. Check the test-plan index, your NHA account, or NHA directly for your appointment.

Do I really need to perform 10 EKGs?

Yes — on live individuals, with evidence you can produce. The requirement applies to all CET pathways. An approved pre-externship route may change the completion timing, but it does not erase the requirement.

Can I take the CET exam at home?

Yes, through Live Remote Proctoring when available and compatible with your equipment, room, and accommodations. No breaks are permitted during a remote session.

How soon will I get my results?

A preliminary report may be available immediately after institution-based testing. PSI test-center and remote-proctored reports post within 48 hours. Preliminary results are not final.

How soon can I retake the CET if I fail?

After at least 30 days. You get three attempts at 30-day intervals; after the third unsuccessful attempt, the wait is one year. You pay the full fee each time.

How long should I study for the CET?

There is no honest universal number. Count the hours you actually have, select the correct exam version, split time by official weight, and shift it toward the domains your diagnostic or score report exposes.

How much does the CET exam cost?

NHA does not publish a current amount on a crawlable public page. Check your NHA account: Shop → your profession → Certification Exam.

Does the CET expire?

Yes, after two years. Normal renewal requires 10 CE credits and currently costs $195. Different rules and fees apply after expiration.

Are NHA Mobile flashcards available for the CET?

Yes. NHA says Mobile flashcards are available for most products, and its current exclusion list does not include CET.

How many official NHA CET practice tests are there?

NHA's CET page describes three different online practice tests with two attempts each. NHA says its prep is optional and does not guarantee passing.

Does NHA certification let me perform every EKG-related task in my state?

No. NHA certification eligibility and state practice law are separate. Check the current state authority and employer policy where you plan to work.

Current provider and storefront claims checked August 17, 2026: Pocket Prep's 650-question distribution and access-extension guarantee; the four course-price listings; and the ed2go clinical-placement disclaimer shown on Stephen F. Austin's storefront.

Castleport's own calculations: both version statement counts and density ratios; the 47-distinct-topic count and seven appearances of emergencies in the before-Fall plan; 60 seconds per item; approximate failure counts; the 1.42-point pass-rate range; 70.40% three-year average; 39.5% volume growth; the 4.40-point standard-setting gap; the question-bank distribution; and the $400 course-price spread.

What we could not verify and did not turn into a hard claim:

• A public CET exam fee — use your NHA checkout
• The exact calendar day separating the two Fall 2027 labels
• A wage figure limited to NHA CET holders
• A named CET subject-matter review of this Castleport page; editorial and primary-source verification are complete, and no reviewer attribution has been invented
