RTM Study Guide 2026: How to Pass on Your First Attempt

What You Are Actually Studying For

This guide covers the Registered Technologist - Mammography credential: the American Registry of Radiologic Technologists (ARRT) Mammography (M) discipline, earned through the postprimary pathway and abbreviated on this site as RTM. The ARRT's own discipline designation is Mammography (M); "RTM" is simply the shorthand used here. If you want the plain-language background first, see our explainer on what RTM certification is, or the shorter what RTM stands for page.

The word "postprimary" matters for how you study. You are not an entry-level candidate. You already hold ARRT certification and registration in Radiography, which means the exam assumes fluency in radiographic fundamentals and tests whether you can apply them to a very specific modality with its own regulatory framework, positioning vocabulary, and quality-control culture. Candidates who treat it as "Radiography Part Two" tend to underprepare for the mammography-specific material.

The exam is delivered at Pearson VUE test centers. The content is governed by the Mammography Examination Content Specifications (board approved July 2024, effective September 1, 2025). That document, not a textbook table of contents, is your true syllabus.

Eligibility Comes Before Studying

Many first-time candidates lose weeks because they started studying before they finished documenting. The postprimary pathway has hard prerequisites, and the clinical component is substantial. Our full breakdown lives in the RTM requirements guide, but here is the shape of it.

Education and standing

• Current ARRT certification and registration in Radiography.
• Compliance with ARRT ethics requirements.
• 16 hours of structured education completed within the 24 months before you apply, with at least one credit in each major content category.

Clinical experience

Verified clinical experience must fall within the corresponding 24-month eligibility window. The requirements are specific:

• MQSA compliance in place before you perform any procedures you intend to count.
• Independent mammographic imaging of 75 patients, with no phantom or simulated substitutions.
• All nine prescribed quality-control activities, each at its required repetition count.
• Review of at least 10 mammography cases with an MQSA-qualified interpreting physician.
• At least five elective procedures, completed through observation, assistance, or participation.

Because of those daily caps and per-test QC limits, you cannot compress the clinical work into a few intense weeks. Plan your documentation timeline backward from the date you want to test. The RTM exam dates guide covers scheduling windows and deadlines.

Reading the Blueprint: Where the 115 Scored Questions Sit

The issuer specifies scored-question allocations as counts. This guide keeps them as counts rather than converting them into percentages, because the ARRT does not publish them that way. Remember that 30 additional pilot questions are mixed in and unscored, so you will see 145 items in total.

Procedures alone accounts for more than half the scored exam. If you only have limited study hours, that single fact should shape how you allocate them. For a fuller treatment of each category, read the RTM exam domains guide.

Procedures: The 65-Question Core

Procedures splits into two halves that reward different study habits. One is memory-heavy; the other is spatial and procedural.

The best preparation for the positioning half is not rereading text. It is looking at images and asking, for each one, "Was this adequate, and if not, what exactly would I change?" Your 75 independent clinical exams and your case reviews with an interpreting physician are rich raw material for this. Keep notes on every repeat or supplemental view you perform during your clinical window.

Image Production: 30 Questions on Quality

Thirty scored questions put Image Production second in weight. It is also the domain where your nine documented QC activities pay a direct study dividend, because you have already performed the procedures the exam asks about.

One practical tactic: for each of the nine QC activities you logged, write a two-line summary of its purpose and what a failed result would trigger. That turns clinical paperwork into exam preparation.

Patient Care: 20 Questions Worth Protecting

Twenty scored questions is the smallest allocation, and candidates sometimes skim it. That is a mistake for two reasons. First, these questions are often answerable by careful reasoning, which makes them some of the most recoverable points on the exam. Second, mammography patient interaction carries unique stakes: anxiety about results, discomfort during compression, and sensitive conversations about history and symptoms.

Exam-Day Mechanics and Item Formats

Knowing the mechanics removes avoidable stress. Details below come from the ARRT postprimary handbook and the content specifications.

• Length: 145 questions total, of which 115 are scored and 30 are unscored pilot questions. You will not know which are which.
• Time: 150 minutes of examination answering time. The full appointment is 170 minutes, which includes the tutorial, nondisclosure agreement, and survey.
• Format: Computer-based and primarily single-best-answer multiple choice. Alternative item formats and image-based questions are possible, and the handbook also describes multiple-response and ordered-response formats.
• Navigation: You must answer each item before advancing, but you can flag questions and return to them.
• Reference materials: 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 moving on, build a flagging habit: make your best selection, flag it, and keep going. Image-based questions can eat time, and you want your hardest items revisited with a clear head rather than skipped into oblivion. A rough pacing target is a little over a minute per question, with a reserve for flagged items. For a candid look at which parts candidates find hardest, see how hard the RTM exam is.

Scoring, Pass Rates, and What They Mean for You

The passing score is 75 on ARRT's 1-99 scaled-score range. This is not 75% correct. Scaled scoring adjusts for differences in difficulty across exam forms, so the number of correct answers needed can vary. Do not try to reverse-engineer a raw-score target; instead, aim for consistent strength across all three domains. Our RTM passing score guide explains scaled scoring in more depth.

On pass rates, two figures from the ARRT Annual Exam Report - 2025 are easy to confuse:

The 90.3% figure is not the full-calendar-year pass rate; the two numbers describe different groups. Both indicate that most prepared candidates pass, but remember that these candidates already hold Radiography credentials and have completed substantial clinical documentation. Read more context in the RTM pass rate analysis.

You get three examination attempts within three years of the opening of your initial examination window. That is a safety net, not a plan. The initial application fee is $225 and each reapplication is $200, so a retake carries real cost. The RTM certification cost breakdown lays out the full picture.

A Domain-Ordered Study Sequence

This is the one place we will talk about scheduling, and it is tied directly to the blueprint rather than generic advice. The logic: front-load the heaviest and most image-dependent content, interleave quality control while your clinical memory is fresh, and finish with scenario practice.

If you have more than six weeks, stretch the Procedures blocks first. If you have fewer, keep the order but shorten Patient Care to focused review. When you want to test yourself, use the RTM practice tests to simulate the mixed-domain format, and keep the RTM cheat sheet handy for last-week review.

After You Pass: Keeping the Credential Active

Passing is not the finish line, and understanding the maintenance rules now avoids surprises later.

• Annual renewal: $65, regardless of how many ARRT credentials you hold.
• Continuing education: 24 approved CE credits per two-year biennium. This is per biennium, not per credential, so a single set of credits serves all your ARRT credentials.
• Ethics: Continuing compliance with ARRT ethics requirements.
• Continuing Qualifications Requirements (CQR): For credentials earned on or after January 1, 2011, CQR applies every 10 years. It involves a professional profile, a structured self-assessment, and any prescribed CE. ARRT also lets you accept the maximum CQR CE prescription instead of taking the self-assessment.

If you are weighing the career side, our guides on RTM salary, RTM jobs, and whether the certification is worth it walk through what the credential can mean for your role and employability. Breast imaging centers, hospital-based breast programs, and screening-focused practices are the typical settings where this credential matters.
