- No numeric NCT-specific pass rate or cutoff score was verified in NMTCB sources, so any single percentage you see online is unconfirmed.
- The exam has 150 questions, but only 100 are scored; 50 are unscored pretest items.
- Procedures is about 50% of the blueprint, making it the strongest lever on your result.
- Candidates need 700 documented nuclear-cardiology clinical hours first, so the pool is experienced, not a random sample.
What the Published Data Actually Shows
If you searched for the "NCT pass rate 2026," you probably wanted one clean number: a percentage that tells you whether to feel confident or nervous. Here is the honest answer for the Nuclear Cardiology Technologist examination from the Nuclear Medicine Technology Certification Board (NMTCB): no NCT-specific pass rate was verified in the issuer's published sources, and no numeric cutoff score was verified either.
That absence is itself useful information. It tells you which claims to trust and which to discard, and it points you toward the variables you can control. This article walks through what is known about the exam's structure, who takes it, how scoring is determined, and how to convert the available facts into a realistic preparation plan. For related context, see our guides on how hard the NCT exam is and the NCT passing score.
Why No NCT-Specific Pass Rate Is Published
NMTCB describes how it sets the passing criterion, but the sources reviewed do not give a numeric pass percentage for this specialty exam. Several structural reasons explain why a clean, trustworthy pass rate is hard to produce:
- Criterion is set per form. NMTCB establishes the passing criterion for each examination form using the content of the exam, item performance, and statistical review. Because forms are not interchangeable word-for-word, there is no single fixed raw score that applies to everyone.
- On-demand testing. The exam is administered by IQT, Inc. (Iso-Quality Testing) at test centers on demand, within a roughly six-month authorization window. Candidates test continuously rather than all on one national date, so there is no single "sitting" to report on.
- Small, specialized population. Nuclear cardiology is a niche specialty within nuclear medicine technology. Small cohorts make year-to-year percentages volatile even when they are published.
- Pretest items. Because 50 of the 150 questions are unscored pretest items, what a candidate experiences as "the exam" is not identical to what is scored.
The practical takeaway: treat the lack of a published figure as a reason to prepare against the content outline rather than against a statistic. Our NCT pass rate coverage will stay anchored to what the issuer actually documents.
Who Sits for This Exam: The Candidate Pool
Even without a published percentage, you can reason about the population taking the test, and that matters for how you interpret any anecdotal pass claims. NCT is not an entry-level credential. To qualify you must hold active NMTCB, ARRT(N), or CAMRT nuclear-medicine certification and document at least 700 nuclear-cardiology clinical hours as a certified or registered technologist.
Those hours involve real work: radiopharmaceutical handling, imaging, and injections where permitted, performed under the qualifying physician or under direct supervision by a certified technologist as NMTCB specifies. Employers verify the experience. By the time someone applies, they have already spent substantial time around stress labs, camera systems, and tracer preparation.
What this means for you
A self-selected, experienced pool tends to be better prepared than a general population. That cuts two ways:
- You are competing against your own standard, not against a curve, because the criterion is set per form from exam content and statistics.
- Your clinical hours are an asset, but daily practice in one lab can leave blind spots in procedures your site rarely performs.
For the full eligibility picture, review our NCT requirements breakdown before you apply.
Exam Format and How Scoring Works
Understanding the mechanics removes a lot of anxiety that pass-rate hunting tends to create. Here are the confirmed format details:
| Element | NCT Detail |
|---|---|
| Question count | 150 four-option multiple-choice questions |
| Scored vs. pretest | 100 scored, 50 unscored pretest |
| Time allowed | Three hours |
| Delivery | On-demand, closed-book computer testing at test centers via IQT, Inc. |
| Navigation | Answer before advancing; may flag, review, and change answers |
| Calculator | Bring your own noiseless battery- or solar-powered calculator without text storage; none supplied |
| Passing criterion | Set per form by NMTCB; no numeric cutoff verified |
The pretest-item reality
One-third of what you see is unscored, and you cannot tell which items those are. Candidates sometimes hit a brutal run of unfamiliar questions mid-exam and conclude they are failing. Often they have simply landed on pretest items. The right response is to answer every question as carefully as the last, flag anything uncertain, and keep moving rather than letting a handful of odd items derail your pacing across three hours.
The calculator detail
Calculations are fair game, and the policy that you supply your own approved calculator is the kind of logistical detail that costs people composure on test day. Confirm yours has no text-storage capability and practice with it beforehand. Dose, decay, and rate-type calculations are far easier when your hands already know the device.
Reading the Blueprint as a Pass-Probability Map
Since no pass rate exists to guide you, the content outline is your best predictor of where points come from. The current outline is the NCT Content Outline 2023, effective October 1, 2023, and the issuer's catalog still identifies it. NMTCB's Summer 2026 job-task-analysis report discusses potential future revisions, but it is not a replacement effective blueprint. All five published percentages are approximate, so read them as emphasis guides rather than exact item counts.
| Domain | Approx. Weight |
|---|---|
| Procedures: Indications, Instrumentation, Acquisition, and Processing | ~50% |
| Radiopharmaceuticals and Interventional Drugs: Properties, Indications, Contraindications, Dosages, Biodistribution, and Adverse Effects | ~15% |
| Non-Pharmacologic (Exercise) Stress Testing | ~15% |
| Anatomy/Physiology/Pathology | ~10% |
| Patient Care | ~10% |
Domain 1: Procedures (about half the exam)
This single domain carries roughly as much weight as the other four combined. Expect questions rooted in the actual workflow of a myocardial perfusion study:
- Appropriate indications for a given study and how they shape protocol choice
- Camera and instrumentation concepts, including detector performance and quality control
- Acquisition parameters and gated imaging considerations
- Processing steps, reconstruction concepts, and recognizing artifacts that could mimic disease
Domain 3: Radiopharmaceuticals and Interventional Drugs
This domain rewards precise recall. Candidates must know the properties, indications, contraindications, dosages, biodistribution, and adverse effects of both the imaging agents and the drugs used to provoke stress.
- Tracer-specific characteristics that affect timing and protocol
- Pharmacologic stress agents, including when each is contraindicated
- Recognizing and responding to adverse effects
Domain 4: Non-Pharmacologic (Exercise) Stress Testing
Fifteen percent is a meaningful block, and it is highly learnable. Focus on protocol logic, endpoints, monitoring, and the conditions under which a test should be stopped or modified.
Domains 2 and 5 together make up roughly a fifth of the exam: anatomy, physiology, and pathology, plus patient care. They are smaller, but they are often where experienced technologists lose easy points by skimming them. For a deeper walk-through of each area, see our NCT exam domains guide.
Fees, Windows, and the Cost of a Failed Attempt
Because the pass rate is unpublished, think in terms of attempt economics. The standard nonrefundable application/exam fee is $225. The $150 promotional rate that ran February 1 to 28, 2026 has expired, so do not plan around it. A separate PET + NCT combination application costs $350 and lets you complete eligibility requirements and both distinct examinations within three calendar years of application. It does not merge the exams or change the scope of NCT preparation.
The upside of passing is durable. Certification lasts seven years, with annual registration and a requirement to keep your underlying nuclear-medicine credential active throughout. You can recertify by examination or through 42 NCT-specific continuing education hours earned during the seven-year cycle; the CE recertification application fee is $250. The 24 CE credits awarded for passing a specialty exam are a separate matter from that 42-hour pathway. An expired specialty credential requires re-examination rather than the CE route.

Scheduling Your Prep by Domain
Rather than generic study advice, let the blueprint dictate the order. The logic: front-load the heavy, interconnected material, then use later weeks for recall-heavy drug content and for mixed practice. This sample arc assumes about six weeks and should be stretched if your clinical exposure to certain procedures is limited.
Procedures, part one
- Indications and protocol selection for each study type your lab performs and ones it does not
- Instrumentation and quality-control concepts
- Acquisition parameters and gating
Procedures, part two plus stress testing
- Processing, reconstruction, and artifact recognition
- Exercise stress protocols, endpoints, monitoring, and termination criteria
Radiopharmaceuticals and interventional drugs
- Properties, dosages, and biodistribution of each agent
- Contraindications and adverse effects for pharmacologic stress drugs
Anatomy/physiology/pathology and patient care
- Coronary anatomy and how disease patterns appear on perfusion images
- Patient preparation, communication, and safety scenarios
Timed mixed practice
- Full-length sets with your approved calculator
- Review misses by domain and revisit the weakest one
For a fuller methodology, our NCT study guide goes deeper, and the NCT cheat sheet is a useful final-week review. When you want realistic question practice, use the NCT practice tests.
Key Takeaway
Track your practice results by domain, not just overall. Because Procedures is about half the blueprint, a weak showing there is far more dangerous than a weak showing in Patient Care, and your tracking should make that visible.
Pass-Rate Claims to Distrust
Because the gap in published data invites filling, you will encounter confident-sounding numbers. Apply these filters:
- Percentages without a source. If a site cites a pass rate but cannot point to an NMTCB document, treat it as unverified.
- Numbers from another credential. Several certifications share the NCT acronym. A statistic from a different NCT credential has no bearing on the Nuclear Cardiology Technologist exam.
- Numbers from the physician exam. The CBNC physician examination is a different test for a different audience.
- A fixed raw cutoff. Since the criterion is set per form, a claim that you need exactly some fixed count of correct answers is not supported by the issuer's described process.
- "Official" practice questions. NMTCB does not publish, produce, or recommend particular commercial study guides. Independent practice content, including ours, is preparation material and not official exam items.
If the terminology around the credential itself is still fuzzy, our explainers on what NCT certification is and what NCT stands for clear up the acronym confusion that causes these cross-credential mix-ups.
Frequently Asked Questions
No NCT-specific pass rate was verified in NMTCB's published sources, so there is no reliable figure to quote. NMTCB sets the passing criterion for each exam form using exam content, item performance, and statistical review rather than publishing a single fixed percentage.
No numeric cutoff was verified. The exam contains 150 questions, of which 100 are scored and 50 are unscored pretest items, and the passing criterion is set per form. Aim for solid command of every domain, especially Procedures at roughly half the blueprint.
No. Pretest items are unscored, but you cannot identify them while testing, so treat every question as if it counts. A run of unfamiliar items does not necessarily mean you are failing.
The standard application/exam fee of $225 is nonrefundable, so a new attempt means planning for that cost again. Use your results to identify weak domains before rebooking, rather than retesting right away.
No. Several unrelated credentials use the NCT acronym, and their statistics, fees, and structures do not apply to the Nuclear Cardiology Technologist exam from NMTCB. Rely on NMTCB documentation and the current 2023 content outline for this credential.
In the absence of a published pass rate, the most reliable predictor of your outcome is how well you have covered the blueprint, and Procedures is where the points are. Start with the domain-by-domain guide, practice under realistic timing with the NCT practice tests, and book your attempt only when your domain-level results are consistent.
