The ARRT Mammography exam presents 115 scored questions plus 30 unscored pilot questions in an appointment of about 2 hours 50 minutes. Under the content specifications effective September 1, 2025, Procedures carries 65 scored questions, Image Production 30, and Patient Care 20, so your study order should start there.
What the ARRT Mammography credential exam covers
The Mammography credential is an ARRT postprimary qualification, and its exam assesses the knowledge and cognitive skills behind entry-level mammography practice. The governing document is the content specifications effective September 1, 2025.
ARRT built the exam from a practice analysis of what entry-level mammographers actually do, and every content category in the outline links to tasks on the published Task Inventory for Mammography. That matters for your preparation: anything in the outline is there because it traces to real practice, and topics outside the outline are not tested.
The current Mammography content specifications were board approved in July 2024 and took effect September 1, 2025. ARRT lists Mammography among its Registered Technologist credentials on its examination content specifications page, where you can download the latest edition. Always confirm you are studying from the version in force on your exam date, because ARRT updates its documents regularly.

Eligibility through the postprimary pathway
You earn Mammography through ARRT's postprimary eligibility pathway, which requires a supporting credential, qualifying education, an ethics review, and the exam. Confirm the exact supporting credential in the current handbook before you apply.
The 2026 Postprimary Eligibility Pathway Handbook describes three ways to qualify: you have already earned a supporting ARRT credential through the primary pathway, you hold a supporting credential from another ARRT-recognized organization, or your program director has authorized you to log the required clinical experience and structured education while you finish your educational program.
Mammography appears in the handbook's postprimary eligibility chart alongside disciplines such as CT, MRI, and Breast Sonography. The chart also lists the specific supporting credential each discipline requires, so read that chart directly rather than relying on secondhand summaries. ARRT revises the handbook yearly and states that its policies supersede previous editions.
Two application rules shape your planning. You apply for one credential at a time, and once your exam window opens you have three years to pass, with at most three attempts in that period.

Exam format and what to expect at the test center
The exam has 115 scored questions plus 30 unscored pilot questions, administered at a Pearson test center with 150 minutes of test time in an appointment of about 2 hours 50 minutes.
The handbook's exam format chart for Mammography lists 115 scored items and 30 pilot items, for 140 total. Your appointment includes an 8-minute tutorial, a 2-minute nondisclosure agreement, and a 10-minute survey around the timed portion.
Most questions are multiple choice with one best answer, but the format varies. Some items ask you to select multiple answers, sort options into order, click an image region, or answer after watching a short video clip. Questions appear in random order, and pilot questions are not identified; they do not affect your score.
Practical test-day rules from the handbook: arrive 30 minutes early, bring two valid forms of acceptable ID, and leave phones and other belongings outside. Accept the nondisclosure agreement within two minutes of it appearing, and flag difficult questions so you can return to them if time allows.
A few policies are worth knowing before something goes wrong. Arriving without proper ID means forfeiting your application fee and reapplying. Missing your appointment or failing to cancel properly also forfeits the fee, though it does not count as one of your three attempts. Request ADA accommodations on your application itself; the process runs through an independent company ARRT contracts with, and your application is on hold until the review finishes.
- Two valid forms of acceptable ID, matching the name on your ARRT file
- Arrive 30 minutes before your appointment
- No cell phones or personal belongings in the testing room
- Accept the nondisclosure agreement within two minutes
- Flag hard questions and revisit them before time runs out

The three content categories and their weights
The scored questions split across three categories: Patient Care (20), Image Production (30), and Procedures (65), for 115 scored questions in total.
The published weights tell you where the exam concentrates. Procedures alone accounts for roughly 57% of scored questions, and within it the positioning subcategory is the single largest block on the exam. These percentages are simple arithmetic from the official counts, not a prediction of what any individual exam form will emphasize.
Read the outline itself for the subtopics inside each category. Patient Care covers patient communication, assessment, breast cancer treatment terminology, and results handling. Image Production spans unit design, digital acquisition and informatics, quality assurance, quality control tests, and technique and image evaluation. Procedures covers breast anatomy, physiology, and pathology, then positioning and both screening and interventional procedures.
| Content category | Scored questions | Subcategories |
|---|---|---|
| Patient Care | 20 | Patient Interactions and Management (20) |
| Image Production | 30 | Image Acquisition and Quality Assurance (30) |
| Procedures | 65 | Anatomy, Physiology, and Pathology (26); Mammographic Positioning and Procedures (39) |
| Total | 115 |

Building a study order from the published weights
Start with Procedures, especially the 39-question positioning subcategory, then Image Production, then Patient Care, and match your depth to the outline's own cues rather than treating every line as equal.
The outline contains explicit depth instructions. For positioning, it directs you to the ACR Mammography Quality Control Manual (Clinical Image Quality, 1999) and notes that approximately six items cover the standard craniocaudal and mediolateral oblique views, so the other positioning questions draw on the broader view and patient-variance list. For quality control, the mammographer tests require detailed understanding while the medical physicist tests require only basic understanding, including their purpose, frequency, and performance criteria. Breast ultrasound, breast MRI, and interventional procedures carry an explicit basic-knowledge expectation in the outline, and breast cancer treatment options are tested at the level of definitions and basic descriptions.
ARRT does not recommend or endorse any review program, mock registry, or study guide, and it publishes no textbook list, because its exams draw on many references. Build your plan from the content specifications and the Task Inventory on ARRT's website, and treat any commercial course as supplemental.
The following exercise checks whether you actually know your way around the outline, which is the map every study session depends on.
Practice exercise
Using the official content categories, assign each of these outline topics to its correct category and subcategory: (a) explaining pre-exam instructions such as removing deodorant, (b) phantom image quality testing, (c) clock-position localization terminology, (d) implant-displaced (ID) views, (e) MQSA recordkeeping requirements.
Show answer
(a) Patient Care, under Patient Interactions and Management. (b) Image Production, under Image Acquisition and Quality Assurance, in the mammographer quality control tests. (c) Procedures, under Anatomy, Physiology, and Pathology, in Localization Terminology. (d) Procedures, under Mammographic Positioning and Procedures, in the Views list. (e) Image Production, under Image Acquisition and Quality Assurance, in Quality Assurance and Evaluation.
Every item comes directly from the published outline. Deodorant removal is listed as an example of pre-exam instructions within patient communication. The phantom image appears in the list of mammographer QC tests. Clock position is the first localization term named. The implant-displaced view is one of the enumerated positioning views. MQSA regulations, including recordkeeping, sit inside the quality assurance subcategory. Knowing which category a topic belongs to lets you find it in the outline, prioritize it by weight, and track misses by category during review.

Preparation mistakes to avoid
The most costly mistakes are misjudging depth, skipping the small category, and using unofficial exam content, and the outline and handbook each flag one of these directly.
Do not dismiss Patient Care because 20 questions looks small. It is about 17% of your score and includes concrete content such as risk-factor assessment, the ACS and ACR screening guidance named in the outline, and how patients receive results. Twenty scored questions is too large a block to leave underprepared.
Do not flatten the outline's depth cues. Studying medical physicist QC tests in detail wastes time the outline says only needs basic understanding, while underpreparing the detailed mammographer QC tests or the positioning views list leaves the largest scoring areas thin. Where the outline references external manuals, such as the 2018 ACR Digital Mammography Quality Control Manual, get specifics like frequencies and performance criteria from those documents rather than from memorized secondhand figures.
Do not touch recalled or reconstructed exam questions. ARRT's security rules prohibit sharing or receiving information substantially similar to actual exam wording, violations fall under its Rules of Ethics, and sanctions can include ineligibility or revocation. Using leaked content risks the credential you are studying for.
