NHA CET Exam Scoring and Test Day 2026: How the EKG Technician Exam Is Scored, What to Bring, and How to Pace 120 Minutes

NHA CET in 2026: A Scoring and Test-Day Companion

Last updated: July 3, 2026. Verified against the NHA CET certification page, the official CET test plan, the NHA Candidate Handbook, and the NHA 2025 annual pass-rate report.

The NHA Certified EKG Technician (CET) exam is a two-hour, 120-question credentialing test that you can pass on the first try when you understand how it is scored and how test day works. This guide is the scoring and logistics companion to the OpenExamPrep NHA EKG CET study guide and the NHA EKG lead placement and rhythm interpretation guide. It does not repeat the 6-week study plan or the lead-placement landmarks. Instead it answers the questions that decide test-day execution: how every item is scored, what the 390 cut score means, what to bring, how check-in works, how to read a score report, what retakes cost, and how to pace 120 minutes.

Exam at a Glance

The official NHA CET certification page confirms the two-hour length and the three delivery modes. The official CET test plan lists 100 scored items plus 20 pretest items and the three domains. The NHA Candidate Handbook sets the scaled score range, the 390 passing score, the retake rules, and the test-day conduct rules.

How the CET Is Scored

NHA does not score the CET as a simple percentage. The NHA Candidate Handbook describes a scaled scoring model from 200 to 500. The raw number of correct scored items is converted to a scaled score that adjusts for the difficulty of the specific exam form you receive, so a harder form does not require more correct answers than an easier form. The passing scaled score is 390.

Three scoring facts change test-day behavior:

1. Only 100 of the 120 questions are scored. The other 20 are pretest items that NHA is validating for future forms. They are randomly distributed and you will not know which they are, so treat every question as scored.
2. Unanswered questions are scored as incorrect. There is no penalty for a wrong answer, but a blank is the same as a wrong answer. Answer every question, even with an educated guess.
3. The 390 cut is not a percentage. A 390 out of 500 is not 78%. The scaled conversion means you cannot compute your score from your raw count at the testing screen. Stop trying to calculate it during the exam and focus on pacing.

The three scored domains come from the official CET test plan:

EKG Acquisition is the largest domain, which is why the lead placement and rhythm interpretation guide treats acquisition as the foundation. For a scoring-focused view, the practical takeaway is that acquisition plus safety together account for 76 of 100 scored items. A candidate who is solid on workflow, patient prep, lead landmarks, and artifact control can pass without being a cardiologist-level rhythm reader.

What Test Day Looks Like: Three Delivery Modes

NHA offers three ways to sit for the CET, and the choice changes your logistics.

School-sponsored testing

If your EKG training program is NHA-authorized, your school may administer the exam on-site. The school coordinates the date and roster. The biggest advantage is that preliminary scores are available immediately upon completion, though official results still post to your NHA account. The biggest risk is that you must follow the school's calendar; if you miss the school date, you may have to re-register and pay again.

PSI testing center

You schedule a seat at a PSI testing center through your NHA account. PSI centers are in-person, proctored, and follow standard testing-center rules: photo ID check, roster sign-in, personal items stored out of reach, proctor-provided scratch paper, and a single continuous session. Official results post to your NHA account within two business days.

Live remote proctoring (LRP)

LRP lets you test from home with a webcam, microphone, and stable internet. The proctor checks your ID, scans your room, and monitors you throughout. The rules are stricter than in-person testing because the proctor cannot physically walk the room: no breaks, no leaving camera view, no food, drinks only in a clear container, no one else in the room, no scratch paper (a digital whiteboard is provided), and hands must remain visible. Official results post to your NHA account within two business days.

What to Bring and What to Leave Behind

The NHA what to bring to the testing site page and the Candidate Handbook define ID rules. A current government-issued photo ID is required for every delivery mode, and the name on the ID must match exactly the name you registered with NHA. If the names differ, bring proof of name change such as a marriage license, divorce decree, or court order.

Acceptable ID forms include a driver's license with photograph, state identification card, passport or passport card, permanent resident card, alien registration, and national identification card. For LRP specifically, military IDs are not accepted, paper or temporary IDs are not accepted, credit cards are not accepted, and expired IDs are not accepted.

For in-person PSI testing, the proctor provides two numbered sheets of scratch paper that must be returned before you leave. For LRP, scratch paper is not allowed at all; use the digital whiteboard inside the exam.

Check-In: From Door to First Question

For in-person PSI testing, arrive early enough to complete ID check, roster sign-in, and storage of personal items before your scheduled time. The proctor initials the roster next to your name after verifying your ID. Use the restroom before the exam starts: restroom breaks during the exam are allowed with proctor approval, but the timer does not stop and the lost time is not made up.

For LRP, the NHA PSI exam readiness checklist and the PSI check-in process require you to log in at least 15 minutes before your scheduled exam time. The check-in specialist photographs your ID, takes a selfie, and runs a live room scan with your webcam. If you do not start within 15 minutes after your scheduled time, you forfeit your exam fee. If you have a technical issue, contact PSI Tech Support at 844-267-1017 or through the Live Chat button in the Secure Browser within 30 minutes of your start time, or you forfeit the fee.

The exam itself is one continuous session. An on-screen timer shows remaining time. You can flag questions for review, and you must unflag every flagged question before you can submit. There is no pause button, and the timer does not stop for breaks.

Reading Your Score Report

The score report is the document you use to decide what to do next, whether you passed or failed. The Candidate Handbook describes three sections:

1. Overall pass/fail status and scaled score. The single number between 200 and 500, with 390 as the pass line.
2. Domain-level diagnostic indicators. Each major content area is marked Above the passing standard, Near the passing standard, or Below the passing standard. Areas with five or fewer questions show N/A, because the sample is too small to interpret reliably.
3. Result by delivery mode and date. Confirm the exam date and delivery mode so you can match the report to your appointment.

The diagnostic indicators are the most useful part for retake planning, but they cannot be added up to predict the overall result. A candidate with two Near domains and one Below domain may still pass or fail depending on where the 100 scored items concentrated. Use the indicators as a study map, not as a scorecard.

For school-sponsored exams, preliminary pass/fail results are available immediately, but the official scaled score and diagnostic indicators post to your NHA account afterward. For PSI and LRP, everything posts within two business days. Passing candidates can print their certificate from the My Achievements section of their NHA account.

Retake Policy and Recovery

NHA's retake policy, set in the Candidate Handbook, is structured around waiting periods and attempt limits rather than a cap on total tries.

Each retake requires a fresh exam application and full fee payment through your NHA account. There is no discounted retake fee. If you fail three times, the one-year wait is mandatory; you cannot pay to shorten it.

If you need to reschedule rather than retake, the handbook allows you to reschedule to a new date within six months of the original appointment without paying again, provided you cancel or reschedule at least 24 hours before the scheduled time for PSI or LRP exams. A no-show or a late cancellation forfeits the fee. School-sponsored exams follow the school's reschedule policy, which is usually less flexible.

A Test-Day Pacing and Question-Attack Strategy

The CET gives you 120 minutes for 120 questions, which is one minute per question on average. That is enough time, but only if you do not let a single rhythm strip eat five minutes. Use a three-phase pacing model:

Within each question, use the same attack order the lead placement guide describes for rhythm strips: assess signal quality first, then regularity, rate, P waves, PR interval, and QRS width. For safety and workflow questions, eliminate the option that is technically possible but workflow-unsafe before you pick anything.

Two pacing rules protect your score:

• Never leave a question blank. Unanswered items are scored as incorrect. With one minute per question, you always have time to guess.
• Do not unflag early. Keep flagged questions flagged until the final 30 minutes, when you have a clear head and a known time budget.

Avoiding Panic on Rhythm Strips

Rhythm strips are the most common panic trigger on the CET. A complex strip with artifacts and an unfamiliar rate can make a candidate freeze, then over-focus, then run out of time on later questions. A short protocol keeps panic from costing you points:

1. Check quality first. If the tracing is noisy, the answer is usually about acquisition, not rhythm. Loose lead, patient movement, and AC interference all produce patterns that look like pathology until you read the quality.
2. Run the five checks. Regularity, rate, P waves, PR, QRS. Do them in the same order every time.
3. Classify before you name. Decide sinus, atrial, junctional, ventricular, or heart block before you commit to a specific label.
4. Flag and move. If two checks conflict and you cannot decide in 90 seconds, flag the question and keep moving. You will usually see the answer more clearly on a second pass.

The point is not to become a cardiologist in two hours. The point is to keep one strip from sinking your pacing on the 99 other items.
