What "Pass Rate" Means for the CLLRT
Search for the Limited Licensed Radiologic Technologist pass rate and you will find confident-sounding percentages on forums, prep sites, and social posts. Before you anchor your confidence (or your anxiety) to any of them, you need to know what a pass rate actually measures and whether anyone has credibly published one for this credential.
A pass rate is the share of test-takers who meet the passing standard during a defined window. Three things must be public for the figure to mean anything: the number of candidates, the number who passed, and the period covered. Without all three, a percentage is just a claim.
The CLLRT credential is governed by American Allied Health. Its scope is built from a government-published outline, the Oklahoma CareerTech badge 8541 document, which lists twelve weighted examination criteria. That document describes what the credential covers. It does not report how many people passed.
What Published Data Actually Exists
Three official sources define what is knowable about this credential right now:
- The Oklahoma CareerTech badge 8541 document for the Limited License Radiology Technologist credential. This is a government-published credential outline. It is undated, and it is not an AAH-authored 2026 handbook.
- The American Allied Health certification page for the Certified Limited Licensed Radiology Technician credential, which is currently active.
- An AAH announcement on online certification exam updates for 2027, which states that revised CLLRT content begins in February 2027.
None of these publishes cohort-level pass statistics. That absence is itself a finding. It means any specific percentage you encounter is either sourced from somewhere not reviewed here, extrapolated from a different credential, or fabricated. Because several well-known credentials share the "CLLRT" acronym, cross-contamination is a real risk: a number attached to a different certification can easily get pasted onto this one.
| Question | What the Reviewed Sources Establish |
|---|---|
| Is there a verified 2026 pass rate? | No published figure in the reviewed sources |
| Who governs the credential? | American Allied Health |
| What defines the content? | Twelve weighted criteria from the Oklahoma CareerTech badge 8541 outline |
| Is badge 8541 an exam code? | No, it is a state document number |
| Does it replace ARRT or state licensure? | No |
| Is revised content coming? | Yes, announced for February 2027 |
Why a Single Percentage Would Mislead You
Even if a pass rate were published tomorrow, a single headline number would tell you less than you might hope. Here is why, specific to a credential like this one.
The candidate pool is not uniform
Limited-scope radiography credentials draw people from very different starting points: someone who already works in a physician's office and takes X-rays under supervision, a recent graduate of a limited-scope program, a medical assistant adding a skill. A blended pass rate averages together groups with very different preparation. Your personal likelihood of passing depends on your preparation against the content outline, not on the average of everyone else's.
The content is unusually broad for a "limited" credential
The twelve criteria range from medicolegal responsibilities to drug administration to bone densitometry. A candidate can be strong in positioning and weak in mathematics and still be blindsided. Breadth, not depth in any one area, is the defining feature of this exam's difficulty. For a fuller discussion of that, see How Hard Is the CLLRT Exam? Complete Difficulty Guide 2026.
Version changes break year-over-year comparisons
With revised content announced for February 2027, any historical pass rate describes a version of the exam that is about to change. A number from the prior scope would not predict outcomes on revised content.
The Twelve Criteria Behind Every Result
Since the pass rate cannot be pinned down, the productive move is to study against what is documented: the twelve weighted examination criteria. These are the domains your preparation should map to, and each one is a place where candidates can gain or lose ground. For a detailed walk-through, the companion piece CLLRT Exam Domains 2026: Complete Guide to All 12 Content Areas goes domain by domain.
| Domain | Name |
|---|---|
| 1 | The Profession and the Professional |
| 2 | The Framework of Radiographic Equipment |
| 3 | Essential Mathematics for Limited Machine Operators |
| 4 | Foundational Physics for Radiography |
| 5 | The Safety Precautions of Radiation |
| 6 | Introduction to Anatomical Positioning |
| 7 | Image Acquisition & Evaluation |
| 8 | Medicolegal Aspects of Radiography |
| 9 | Safety Implementation and Infection Control |
| 10 | Evaluation of Patients in Acute Situations |
| 11 | Drug Administration |
| 12 | Bone Densitometry |
Notice the shape of this list. It blends technical content (equipment, physics, image evaluation), quantitative content (mathematics), patient-care content (acute situations, drug administration, infection control), and professional content (the profession, medicolegal aspects). A candidate who prepares only for the technical block is leaving a large share of the outline unaddressed.
Where Candidates Tend to Struggle
Because no cohort data is published, the following is reasoning from the structure of the outline, not a statistic. These are the areas where the nature of the material makes gaps most likely for people entering from a hands-on background.
Domain 3: Essential Mathematics for Limited Machine Operators
Hands-on technologists often learn technique by habit and chart rather than by calculation. The exam outline names mathematics as its own domain, which signals that you should be comfortable working with numbers rather than relying on lookup habits.
- Practice setting up and rearranging relationships between exposure variables
- Be fluent with unit conversions and basic algebraic manipulation
- Work problems without a calculator-dependent shortcut you have never verified
Domain 4: Foundational Physics for Radiography
Physics explains why technique choices work. Candidates who memorized "what to dial in" sometimes struggle when asked why, or what happens when a variable changes.
- Understand how the beam is produced and what influences it
- Connect physics concepts to their effect on the image and on the patient
Domains 10 and 11: Acute Situations and Drug Administration
These two domains pull you out of pure imaging and into patient assessment and medication knowledge. For a limited-scope operator who rarely handles either on the job, they can feel unfamiliar, which is exactly why they deserve deliberate study time.
- Review recognizing a patient who is deteriorating and how to respond within your role
- Review core drug administration concepts the outline expects you to know
Domain 12: Bone Densitometry
Bone densitometry is a specialized topic that many general limited-scope workers never touch. Because it is a named domain, expect to be tested on it regardless of your daily duties.
Key Takeaway
The biggest risk is not a hard domain; it is a neglected one. Audit the twelve criteria against your work experience and give the most study time to the areas your job never exercises.
How to Verify Anything You Read About This Exam
The CLLRT acronym is shared by several credentials, and the web is full of pages that blur them together. Use this checklist before trusting any claim about pass rates, passing scores, fees, or question counts.
- Confirm the credential. The page should clearly refer to the Limited Licensed Radiologic Technologist credential governed by American Allied Health, not a different certification that happens to abbreviate the same way.
- Trace the number to a source. A real figure points to a document, a date, and an authority. A vague "most candidates pass" does not count.
- Check the version. Does the claim describe current content or content from before the announced revision?
- Go to the primary sources. The Oklahoma CareerTech badge 8541 document and the American Allied Health certification page are the places to confirm scope. Fee, question-count, duration, passing-score, eligibility, and renewal details should be confirmed directly with the governing body rather than taken from third-party summaries.
For the specifics people most often ask about, see the dedicated pages on CLLRT passing score, CLLRT certification cost, and CLLRT requirements, and confirm anything time-sensitive with American Allied Health before you commit.
2026 Timing: Current Scope vs. the 2027 Revision
The most useful "data point" available right now is not a percentage; it is a date. American Allied Health has announced revised CLLRT content beginning February 2027. The scope that applies to October 2026 is the current one, not the revised one.
That has practical consequences:
- If you are testing in 2026, prepare against the current twelve-criteria outline and do not spend time chasing rumors about what the revision will contain.
- If you are weighing whether to wait, understand that waiting means studying a different scope. There is no basis in the reviewed sources to assume the revised version will be easier or harder.
- If you read an article describing "the new exam," check whether it is describing the current scope or the announced 2027 revision, and whether it cites AAH directly.
Sequencing the Twelve Domains for Study
This is the one place where study planning belongs, and it is tied directly to the outline. Because there is no pass-rate data to tell you where to focus, sequence your preparation by dependency: master the foundations that later domains build on, then layer on patient-care and professional material, then finish with the specialized topics.
Foundations: Domains 3 and 4
- Rebuild mathematics fluency (Domain 3)
- Learn the physics that underlies technique (Domain 4)
- These support equipment, safety, and image-evaluation questions later
Equipment, Safety, and Imaging: Domains 2, 5, 7
- Equipment framework (Domain 2)
- Radiation safety precautions (Domain 5)
- Image acquisition and evaluation (Domain 7)
Patient Care and Practice: Domains 6, 9, 10, 11
- Anatomical positioning (Domain 6)
- Safety implementation and infection control (Domain 9)
- Acute-situation evaluation (Domain 10)
- Drug administration (Domain 11)
Professional and Specialized: Domains 1, 8, 12, then review
- The profession and the professional (Domain 1)
- Medicolegal aspects (Domain 8)
- Bone densitometry (Domain 12)
- Mixed review across all twelve domains
If you want a more complete plan, the CLLRT Study Guide 2026: How to Pass on Your First Attempt expands on preparation, and the CLLRT Cheat Sheet 2026: One-Page Review of Must-Know Facts is useful for a last-pass refresher. To pressure-test your readiness across all twelve areas, take a timed set on the CLLRT practice test site and note which domains drag your score down.
Key Takeaway
Treat practice results as your own personal "pass rate." A score broken down by domain tells you far more about your odds than any population-level percentage could.
It also helps to keep the credential's boundaries straight. This certification is not a substitute for ARRT certification or state licensure, so a pass here does not by itself settle questions about where you may practice.
