- The NMTCB initial NMAA exam is approximately 200 multiple-choice items with four or five response options each.
- No numeric passing score for the initial exam was established in the public sources reviewed for this article.
- The outline lists four domains with no official percentage weights, so do not trust any "domain percentage" claims.
- The 100-item recertification exam is a separate test; never use its details to plan for the initial exam.
What the Public Record Actually Says About Scoring
Search for the NMAA passing score and you will find confident-sounding numbers on forums, in study-app descriptions, and in competitor articles. Many of them are guesses, and some are borrowed from entirely different credentials that happen to share the same four letters. This article takes a stricter approach: it separates what the Nuclear Medicine Technology Certification Board (NMTCB) has documented for the Nuclear Medicine Advanced Associate credential from what remains unpublished.
Here is the honest bottom line. In the public sources reviewed for this article, a numeric passing score for the initial NMAA examination was not established. That means no verified cut score, no verified scaled-score range, and no verified percentage-correct threshold. If you see a specific number attached to the NMAA initial exam elsewhere, ask for the citation. If there isn't one from the NMTCB, treat it as unverified.
For a broader look at how this credential is structured, see our explainer on what NMAA certification is, which covers the credential's purpose and its place in physician-supervised nuclear medicine practice.
The Format Behind the Score: Roughly 200 Multiple-Choice Items
While the cut score is not public, the format is. The NMTCB describes the initial Nuclear Medicine Advanced Associate examination as approximately 200 multiple-choice items, with four or five response options per question. The exam is computer-based and delivered by IQT, Inc. at local test centers, with standing administrations in January and July.
What that format implies for how you prepare:
- Breadth over depth in any single sitting. With around 200 items spread across four domains, no single topic can carry you. A weak area in one domain can be offset only if your other domains are genuinely strong.
- Four- and five-option items. Some questions will have a fifth distractor, which slightly lowers the odds of a lucky guess and raises the premium on actual discrimination between similar-sounding answers.
- Computer-based delivery. You will read clinical scenarios and calculations on screen. Practice with on-screen reading, not just printed notes.
Not sure how demanding that format is relative to your background? Our NMAA difficulty guide walks through what makes the exam challenging for working technologists moving into an advanced role.
What Has Not Been Published (and Why It Matters)
Candidates often assume that any professional certification publishes a pass mark, a time limit, and a pass rate. For the initial NMAA exam, the public sources reviewed did not establish several of these. To keep your planning grounded, here is a clear separation of known and unknown.
| Item | Status in Public Sources Reviewed |
|---|---|
| Approximate number of items (initial exam) | Approximately 200 multiple-choice items |
| Response options per item | Four or five |
| Delivery | Computer-based, IQT, Inc., local test centers |
| Standing administrations | January and July |
| Numeric passing score | Not established in public sources reviewed |
| Initial-exam time limit | Not established in public sources reviewed |
| Current NMAA-specific pass rate | Not verified |
| Official domain percentage weights | Not published in the content outline |
If you are curious about whether any current success statistics exist, our NMAA pass rate article explains what data has and has not been verified.
Four Domains, No Published Weights
The NMTCB's Nuclear Medicine Advanced Associate Examination Content Outline (revised November 2025, distributed as NMAAContentOutline_2026.pdf) lists four domains. Critically, the outline presents them as unweighted official examination objectives. There are no official percentage weights, so nobody can legitimately tell you which domain is "largest" or how many questions come from each.
That matters for scoring strategy. Because you cannot know how items are distributed, the safest plan is balanced competence. The outline also frames practice as physician-supervised, excluding independent practice and final interpretive authority, and it uses generic or common drug names rather than brand names. Expect your exam vocabulary to match.
Domain 1: Patient Care (Assessment, Management, Reporting, and Education)
The patient-facing domain. Candidates should be ready to reason through assessment, management decisions within a supervised role, communication of findings through appropriate channels, and patient education.
- Distinguish what falls within advanced-associate scope versus physician interpretive authority
- Prepare to handle scenario questions about patient status, safety, and follow-up
- Practice articulating education points clearly, since wording-based distractors are common
Domain 2: Clinical Procedures
The procedural core of nuclear medicine practice, including how studies are planned, performed, and monitored.
- Know protocol logic, not just step lists: why a parameter is chosen matters
- Be ready for scenario items where a technical decision depends on patient factors
- Review how procedures change across diagnostic and therapeutic contexts
Domain 3: Diagnostic and Therapeutic Pharmaceuticals
Radiopharmaceutical and adjunct drug knowledge, written using generic and common drug names.
- Train yourself to recognize agents by generic name
- Connect each agent to its purpose, handling considerations, and clinical context
- Pay attention to the diagnostic-versus-therapeutic distinction
Domain 4: Radiation Safety and Radiobiology in Clinical Practice
Safety principles and biological effects applied to the clinical setting.
- Expect applied reasoning, not memorization of isolated definitions
- Link radiobiology concepts to real clinical decisions and protective practices
- Review how safety obligations shape procedures and patient instructions

Passing Score vs. Pass Rate: Two Different Questions
Candidates frequently conflate these. A passing score is the threshold you must reach on the exam. A pass rate is the share of test-takers who clear it in a given period. Neither was verified for the initial NMAA exam in the public sources reviewed.
- A published pass rate would not tell you your personal threshold.
- A published cut score would not tell you how hard the questions are.
- Even with both, your preparation target should remain comprehensive mastery.
Key Takeaway
Treat "what score do I need?" as a question for the NMTCB, and treat "how do I get ready?" as a question you can answer today. Aim for confident, explainable answers across all four domains rather than chasing a threshold nobody has verified publicly.
Before the Score: Eligibility and Application Mechanics
You cannot sit for the exam, and therefore cannot earn a score, until you clear eligibility. The requirements documented in the NMTCB materials include:
- Active primary credential: current NMTCB, ARRT(N), or CAMRT(RTNM) certification.
- Education: successful completion of an NMTCB-recognized NMAA education program. The program recognition guidelines (2019) specify bachelor's-level entry, master's-level preparation, and physician-directed clinical training.
- Clinical hours: 2,000 clinical hours completed as a credentialed nuclear medicine technologist after primary certification and before NMAA-program graduation. Qualifying employment and program clinical placements may be combined, and these are not necessarily 2,000 additional pre-admission hours.
On the money and timing side, the currently linked NMAA application, which bears a 2011 copyright, lists a $1,000 nonrefundable initial fee and asks that you submit at least two months before the examination. Note that this is a legacy application still linked on the NMTCB site, not a newly issued 2026 fee schedule, so confirm the current amount before you pay.
Full eligibility detail lives in our NMAA requirements guide, and the money side is broken down in the NMAA certification cost breakdown. Scheduling specifics are covered in the NMAA exam dates article.
A Domain-Based Preparation Sequence
Since the weights are unpublished and the cut score is unknown, an evenly balanced plan makes sense. The sequence below is organized by domain rather than generic study tricks, and it is a template to adapt to your own strengths and the amount of time before your chosen administration.
Domain 4 first: Radiation Safety and Radiobiology in Clinical Practice
- Safety principles underpin decisions in every other domain, so anchor them early
- Work applied scenarios rather than isolated definitions
Domain 3: Diagnostic and Therapeutic Pharmaceuticals
- Drill generic names until recognition is automatic
- Sort agents by diagnostic versus therapeutic use
Domain 2: Clinical Procedures
- Study the reasoning behind protocol choices
- Connect procedures to the pharmaceuticals and safety rules you already reviewed
Domain 1: Patient Care, then full mixed review
- Rehearse scope-of-practice reasoning within physician-supervised practice
- Finish with mixed sets that interleave all four domains, mirroring the exam
The logic: safety and pharmaceutical knowledge feed directly into procedure and patient-care reasoning, so reviewing them first makes later blocks easier. For a fuller approach to building your plan, our NMAA study guide goes further, and the NMAA cheat sheet is useful for last-pass review. NMTCB does not publish, produce, or recommend particular study guides, and it offers a General Resource List for the credential (2021 file) as a bibliography. That list is a preparation resource, not an alternative exam blueprint or proof of exhaustive coverage.
When you are ready to test yourself, take timed sets on our NMAA practice test site. The questions there are original, independent preparation material, written to build reasoning skills rather than to reproduce actual exam items.
Initial Exam vs. Recertification Exam
One of the most common sources of confusion is mixing up the initial exam with the later recertification exam. They are separate, with different lengths and fees.
| Feature | Initial Certification Exam | Recertification Exam |
|---|---|---|
| Approximate length | About 200 multiple-choice items | 100 items |
| Application fee | $1,000 nonrefundable (legacy application) | $250 |
| When taken | To earn the credential | Years eight through ten of the ten-year cycle, without penalty |
| Numeric passing score | Not established in public sources reviewed | Do not assume it equals the initial exam |
Certification lasts ten years, with annual registration and maintenance of your active primary nuclear-medicine credentials. Every two years you complete 24 standard CE hours plus 24 Category A+ and/or AMA-approved CME hours. Never use the 100-item recertification format to estimate what the initial exam will feel like.

How to Verify Scoring Details Yourself
Because this credential's scoring specifics are not fully public, the right move is to go to the source. A practical verification checklist:
- Start at the NMTCB's initial-examination page (nmtcb.org/exams/nmaa) and read it completely for any scoring or time-limit statements.
- Read the Content Outline PDF (NMAAContentOutline_2026.pdf) and note that the printed November 2025 revision controls over the PDF's legacy 2010 metadata.
- Check the current application and confirm the fee and deadline, since the linked version is a legacy document.
- Contact the NMTCB directly with a written question about scoring policy and time limit, and keep the response.
- Ask your program director what recent graduates of your NMTCB-recognized program have reported about the exam experience.

Frequently Asked Questions
A numeric passing score for the initial Nuclear Medicine Advanced Associate exam was not established in the public sources reviewed. Confirm it directly with the NMTCB rather than relying on unsourced figures.
The NMTCB describes approximately 200 multiple-choice items, each with four or five response options. The shorter 100-item exam is the separate recertification test.
No official percentage weights are published in the content outline, so no domain can be reliably called the largest. Prepare evenly across Patient Care, Clinical Procedures, Diagnostic and Therapeutic Pharmaceuticals, and Radiation Safety and Radiobiology in Clinical Practice.
The initial-exam time limit was not established in the public sources reviewed. Do not infer it from the recertification exam, a practical assessment, or course hours; ask the NMTCB for the current figure.
IQT, Inc. delivers it at local test centers with standing administrations in January and July. The currently linked legacy application lists a $1,000 nonrefundable initial fee and submission at least two months before the exam; verify current details with the NMTCB.
The takeaway: the scoring threshold for the initial NMAA exam is something to confirm with the NMTCB, not guess. What you can control is mastery of all four domains, an accurate understanding of the format, and a well-timed application. Build your readiness on documented facts, and use our practice tests to find and close gaps before exam day.
