RTM Pass Rate 2026: What the Data Shows

Two Pass-Rate Numbers, Two Different Cohorts

If you search for the Registered Technologist - Mammography pass rate, you will find two figures that look almost identical and are easy to confuse. Both come from the ARRT Annual Exam Report - 2025, and both are legitimate. They simply answer different questions.

The 91% number blends candidates who tested under the earlier content specifications with those who tested after the September 2025 revision. The 90.3% number isolates only the first-time cohort that sat for the revised exam. The 90.3% result is not the full-calendar-year pass rate, and the two percentages describe different groups of people. When you quote or compare them, label them accurately.

How to Read the 2025 ARRT Data

High pass rates invite two opposite misreadings: "the exam is easy, I can skip serious preparation" and "the numbers must be inflated." Neither conclusion follows from the data. The more useful reading is structural: the people taking this exam are not a random cross-section of the public.

What the report does and does not tell you

• It reports first-attempt outcomes. The headline figures reflect candidates testing for the first time, not repeat takers.
• It does not break down results by domain in the figures we rely on here. We cannot say which of Patient Care, Image Production or Procedures candidates find hardest, and we will not guess.
• It does not predict your individual result. A cohort rate describes a group, not your personal probability.
• It contains a known source conflict. The report repeats legacy mammography category counts in its revised-exam table. Use the report for cohort pass statistics, and use the dedicated September 2025 content specifications for the blueprint itself.

That last point is worth underlining. If you cross-reference the annual report's category table against the content specifications and the numbers differ, trust the content specifications for what is actually tested. The annual report is your source for who passed, not for what was on the exam.

Who Actually Sits for This Exam

The mammography credential is earned through the postprimary pathway. That detail explains much of the pass-rate story. Candidates are not walking in off the street; they have already cleared a substantial series of gates before they are allowed to schedule a seat at Pearson VUE.

The clinical experience bar is the heavier lift. Candidates must establish MQSA compliance before performing procedures that will count, independently image 75 patients (no phantom or simulated substitutions), complete all nine prescribed quality-control activities at their required repetition counts, review at least 10 mammography cases with an MQSA-qualified interpreting physician, and complete at least five elective procedures through observation, assistance or participation.

By the time someone reaches exam day, they have typically spent months doing the actual work the exam tests. That selection effect is the most defensible explanation for strong first-attempt results, and it is a reason to treat the exam as a validation of on-the-job competence rather than a cold academic test. Our requirements guide walks through each eligibility element in detail.

Practical clinical-logging constraints

A few rules shape how quickly candidates can build a clean record, and they indirectly affect how prepared people are when they finally test:

• A maximum of 16 mammographic procedures may be logged per day across mammograms, QC, image evaluation and electives.
• QC documentation is limited to one submission per day per test.
• The candidate must be physically present for examinations and procedures, but a qualified clinical verifier need not directly observe the work and may verify remotely.
• For image evaluation, a HIPAA-compliant virtual meeting with a remote interpreting physician is permitted while the candidate reviews the same images on a local monitor, though in-person review is recommended.

Why "Pass Rate" and "Passing Score" Are Not the Same Thing

Many candidates misread the passing score as a percentage-correct threshold. It is not. ARRT reports results on a 1-99 scaled-score range, and the passing score is 75 on that scale. A scaled 75 does not mean answering 75% of questions correctly.

The pass rate, by contrast, is simply the share of a defined cohort that reached or exceeded that scaled threshold. The two concepts connect, but one is a bar and the other is an outcome statistic.

What the September 2025 Blueprint Change Means

The controlling document for the current exam is the Mammography Examination Content Specifications (board approved July 2024, V.2024.09.09), effective September 1, 2025. The 145-question exam contains 115 scored items and 30 unscored pilot items, and you cannot tell which is which. Treat every question as if it counts.

The issuer specifies scored-question allocations as counts, and we retain them as counts rather than converting them into purported percentages:

Procedures is the largest category and comprises two sub-areas: Anatomy, Physiology, and Pathology (26 questions) and Mammographic Positioning and Procedures (39 questions). That means Mammographic Positioning and Procedures alone, at 39 scored questions, outweighs Patient Care and Image Production's smaller allocations individually. Understanding this distribution is the single most valuable use of the blueprint. For a full walk-through of each content area, read our domains guide.

Exam Format and Logistics That Affect Your Odds

Knowing the mechanics removes avoidable stress, and stress is a real contributor to underperformance on a test you are otherwise prepared for.

• Delivery: Pearson VUE test centers.
• Length: 145 questions total, with 150 minutes of examination answering time and 170 minutes for the full appointment (tutorial, nondisclosure agreement and survey included).
• Question style: Primarily single-best-answer multiple choice, with possible alternative item formats and image-based questions. The ARRT handbook also describes multiple-response and ordered-response formats.
• Navigation: You must answer each item before advancing, but you may flag and revisit answers.
• Closed book: Basic and scientific on-screen calculators are available, and Pearson can supply a basic four-function calculator on request. Personal calculators are prohibited.

Because you must answer before advancing, the "skip and come back" strategy works only through flagging. Make a best-answer selection, flag it, and move on. With 150 minutes for 145 questions, you have a bit over a minute per item, so pacing discipline matters. Our exam dates guide covers scheduling and testing windows.

Attempt Limits and Retake Economics

Candidates have three examination attempts within three years of the opening of the initial examination window. That is a firm ceiling, and it changes the calculus of "just taking it to see how it goes."

A retake costs $200, and each attempt consumes one of three. Treating your first sitting as a throwaway diagnostic is expensive in both dollars and attempts. Given that the first-attempt data is strong for candidates who arrive prepared, the rational approach is to test when your practice results and clinical readiness align. Our cost breakdown explains fees and long-term maintenance expenses.

Turning the Blueprint Into a Study Sequence

This is the one place we will talk about scheduling, and it is tied directly to the allocation counts above. The logic: spend the most time where the most scored questions live, but sequence so that earlier work supports later work.

Adjust the pacing to your own background. A technologist with years of daily mammography work may compress the clinical-skills weeks, while someone newer to the specialty may need to extend them.

After the Pass: Renewal and CQR

Passing is not the finish line for the credential. To maintain certification and registration, you renew annually and keep meeting ongoing requirements:

• Annual renewal: $65, regardless of how many ARRT credentials you hold.
• Continuing education: 24 approved CE credits per two-year biennium, counted per biennium rather than per credential.
• Ethics: Continuing compliance with ARRT ethics requirements.
• Continuing Qualifications Requirements (CQR): Credentials earned on or after January 1, 2011 require CQR every 10 years, consisting of a professional profile, a structured self-assessment and any prescribed CE. ARRT also permits accepting the maximum CQR CE prescription instead of taking the self-assessment.
