RTM Training

What "RTM Training" Actually Covers

When technologists search for "RTM training," they often expect a single course. The reality is different. Registered Technologist - Mammography is earned through the American Registry of Radiologic Technologists (ARRT) as the Mammography (M) discipline, and it sits on the postprimary pathway. That means there is no single program you enroll in and graduate from. Instead, "training" is a bundle of four separate obligations that all have to line up inside a defined time window: structured education, documented clinical experience, ethics compliance, and finally the examination itself.

Note on naming: RTM is the abbreviation used on this site for the credential. ARRT's official designation for the discipline is Mammography (M). If you are new to the terminology, our explainers on what RTM certification is and what RTM stands for cover the naming in more detail.

This article walks through each training component in the order most candidates encounter them, then connects the training to the exam blueprint so the work you do in the clinic and the classroom pays off on test day.

The Four Training Components You Must Complete

Because RTM is postprimary, the first gate is something you must already hold: current ARRT certification and registration in Radiography. Without it, none of the training below counts toward the credential. From there, the pathway has these parts:

For a full eligibility walkthrough, see RTM Requirements 2026: Eligibility, Prerequisites & How to Qualify. The rest of this article focuses on how to actually execute the training pieces.

Structured Education: 16 Hours with a Catch

The structured education requirement is 16 hours of approved coursework. Two details trip candidates up more than the hour count itself:

• The recency window. The 16 hours must be completed within the 24 months before you apply. Coursework you took three years ago, however good, will not count.
• Content category coverage. You need at least one credit in each major content category. Sixteen hours that all land in one topic area will not satisfy the requirement.

Structured education is also your first real study opportunity. The three exam domains, Patient Care, Image Production and Procedures, are the official major examination content categories, so coursework that touches each of them doubles as exam preparation. Treat every course as a head start on the blueprint, not a box to check.

Clinical Experience: Where the Hands-On Training Happens

The clinical component is the heart of RTM training and the part that takes the longest. The requirements, effective September 1, 2025, are specific and countable:

Logging Rules That Affect Your Pace

Two logging limits shape how fast you can finish:

• A maximum of 16 mammographic procedures per day may be logged across mammograms, QC, image evaluation and electives combined.
• QC documentation is limited to one submission per day per test, so repeating a single QC test several times in one day will not accelerate your progress.

The practical consequence is that QC activities must be spread across many different days. Start them early. A candidate who leaves the nine QC activities until the end of the window often discovers that the one-per-day-per-test rule makes a quick finish impossible.

Verification and Remote Options

You must be physically present for the examinations and procedures you log. However, the qualified clinical verifier does not need to directly observe your work and may verify remotely. For the image evaluation component, the issuer permits a HIPAA-compliant virtual meeting with a remote interpreting physician, provided you review the same images on a local monitor. In-person review is recommended, so use the remote option as a fallback rather than a default.

Preparing for the Exam, Domain by Domain

The exam content is governed by the Mammography Examination Content Specifications (board approved July 2024, effective September 1, 2025). Of the 115 scored questions, the issuer allocates counts across three major categories. We present them as counts, not percentages, because that is how the issuer specifies them.

For a deeper breakdown of each category, read RTM Exam Domains 2026: Complete Guide to All 3 Content Areas.

Domain 3: Procedures (65 of 115)

This is where clinical training and exam preparation overlap the most. Every patient you image independently is practice for the 39 positioning and procedures questions. When you finish a clinical session, spend a few minutes connecting what you did to the underlying rationale: why a given projection was used, what anatomy it demonstrates, and what limits image quality.

Domain 2: Image Production (30 of 115)

Domain 1: Patient Care (20 of 115)

Training Yourself for the Exam Format

Knowing the content is half the job. The other half is being comfortable with how the test is delivered, because format surprises cost points and composure.

• Question count and timing. The exam has 145 questions: 115 scored and 30 unscored pilot questions. You get 150 minutes of answering time within a 170-minute appointment that includes the tutorial, nondisclosure agreement and survey. You cannot tell which questions are pilots, so treat every one as scored.
• Question styles. Most items are single-best-answer multiple choice, but expect possible alternative formats and image-based questions. The ARRT handbook also describes multiple-response and ordered-response formats, so practice selecting several correct answers and sequencing steps, not just picking one option.
• Navigation. You must answer each item before moving on, but you can flag questions and revisit them later.
• Calculators and materials. The exam is 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.

Sequencing Your Training Calendar

Generic study methods matter far less here than sequencing, because the 24-month windows for education and clinical work are the real constraint. A sensible order puts the long-lead items first and reserves the final stretch for blueprint-focused review.

For a structured review plan, pair this with the RTM Study Guide 2026, and keep the RTM Cheat Sheet handy for last-week review.

Fees, Attempts and Scoring to Keep in Mind

Budget for the initial application fee of $225; an examination reapplication costs $200. You have three attempts within three years of the initial exam window opening, so a reapplication should be a considered decision, not a reflex. See RTM Certification Cost 2026 for the full picture and RTM Exam Dates 2026 for scheduling.

The passing score is 75 on ARRT's 1-99 scaled-score range. This is a scaled score, not 75% correct, so do not translate it into a raw-percentage target. For the details, read RTM Passing Score 2026.

Training Doesn't End at Certification

Once certified, ongoing training becomes a maintenance obligation:

• Annual renewal costs $65 regardless of how many ARRT credentials you hold.
• 24 approved CE credits are required per two-year biennium, counted per biennium rather than per credential.
• Ethics compliance continues throughout.
• Continuing Qualifications Requirements (CQR) apply to credentials earned on or after January 1, 2011, on a 10-year cycle. They involve 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.
