ARRT Mammography is a post-primary credential: it is earned by technologists already certified and registered in Radiography who complete ARRT’s structured education and clinical experience requirements and pass the Mammography examination. The examination, under content specifications effective September 1, 2025, presents 145 items — 115 scored and 30 unscored pilot questions — in two and a half hours, weighted most heavily toward Procedures. It is passed at a scaled score of 75. PassProfessor’s Mammography program is in the works.

This guide does the planning work in the open. It states which examination it covers and which it does not; it walks eligibility as the credentialing body publishes it, including the parts candidates most often misread; it takes the published content outline area by area, with a study method for each; it explains scoring in the body’s own terms, including what the score is not; and it closes with a study plan proportioned to the real sitting. Everything factual comes from the primary sources recorded in this guide’s internal sources section. Where the research behind this guide could not pin a fact to a primary source, the fact is omitted and the omission is recorded — a guide that invents a fee or a pass mark to look complete would fail its reader at exactly the moment accuracy matters most.
Which credential is this — a post-primary, not a first credential
This page covers one credential only: ARRT Certification and Registration in Mammography, earned through ARRT’s post-primary eligibility pathway. It presupposes a supporting discipline: for Mammography, the candidate must first be certified and registered in Radiography — the R.T.(R) — and remain in compliance with the ARRT Standards of Ethics. It is not an entry route into imaging, it is not a state mammography license (states layer their own personnel requirements, several of them tied to MQSA, on top of or alongside certification), and it is not the Radiography examination itself, which has its own decided preparation programme. ARRT’s post-primary system also recognises supporting credentials from counterpart registries for some disciplines under its published prerequisite tables; for Mammography, ARRT’s own page states the supporting prerequisite plainly — Radiography — and this page follows ARRT’s statement.
The examination at a glance
| Fact of record | Detail |
|---|---|
| Credential | Certification and Registration in Mammography — American Registry of Radiologic Technologists (ARRT), earned through the post-primary eligibility pathway |
| Supporting prerequisite | Current ARRT certification and registration in Radiography, and continuing compliance with the ARRT Standards of Ethics, as ARRT’s Mammography post-primary page states them |
| Structured education | At least 16 hours of structured education in the content areas ARRT specifies for Mammography, with credit in each required area, completed within the 24 months before application, under the requirements effective September 1, 2025 |
| Clinical experience | Documented clinical experience in mammography under ARRT’s Clinical Experience Requirements — performing mammographic imaging (screening and/or diagnostic) on 75 patients across the required and elective procedure set, logged through ARRT’s post-primary tool (a maximum of 16 entries per day), under the current requirements document |
| Examination format | 145 items in 2 hours 30 minutes at Pearson VUE (170-minute total appointment): 115 scored questions and 30 unscored pilot questions, under the content specifications effective September 1, 2025 |
| Content categories | Patient Care 20 scored questions; Image Production 30 scored questions; Procedures 65 scored questions — of which Anatomy, Physiology, and Pathology carries 26 and Mammographic Positioning and Imaging Procedures carries 39, per the 2025 specifications |
| Passing | A scaled score of 75 on ARRT’s 1-to-99 scaled reporting scale. The scaled score is equated across forms; 75 is not a percentage of items correct |
| Federal frame | Mammography practice is additionally governed by the Mammography Quality Standards Act (MQSA): facility accreditation, personnel, equipment, and quality standards inspected under federal law — examined within the specifications’ regulatory content |
Eligibility, worked through carefully
The post-primary pathway has four standing requirements, and the examination is only the last of them. First, the supporting credential: current ARRT certification and registration in Radiography. Second, ethics: continuing compliance with the ARRT Standards of Ethics, a requirement that runs from application through the credential’s life. Third, structured education: at least 16 hours of education mapped to the content areas ARRT specifies for Mammography, with at least one credit in each required area, completed within the 24 months preceding application, documented through ARRT’s post-primary tool — under the structured education requirements effective September 1, 2025, which reorganised the category minimums. Fourth, clinical experience: the documented performance of mammographic imaging on 75 patients across ARRT’s required and elective procedure set as the Clinical Experience Requirements define it, logged through the same tool, with no more than 16 entries creditable per day — a pacing rule that makes the clinical leg a matter of weeks and months, not a single intensive week.
Only when education and clinical experience are complete and logged does the candidate apply and schedule the examination at Pearson VUE. Two overlays deserve planning attention. MQSA personnel requirements run in parallel with ARRT certification — federal law sets its own initial-training and continuing requirements for mammography personnel, and employers and states enforce both systems — so certificants should map ARRT’s requirements and MQSA’s side by side rather than assuming either contains the other. And ARRT certification itself is maintained: annual renewal and the continuing education ARRT requires on its published cycle keep the credential, and the post-primary credential rides on the supporting Radiography credential remaining current beneath it.
A further discipline applies to every eligibility statement in this guide: eligibility is judged by the credentialing body on its own documents, at application, and rules change between editions of handbooks and packets. Treat this guide’s account as the map and the body’s current document as the territory; where the two could ever differ, the body’s document governs, and checking it costs an hour against the price of a refused application.
The content outline, area by area
Patient Care — 20 scored questions
Patient interaction and management in the mammography suite: history and risk assessment — including the inherent and social risk factors the 2025 specifications added — patient education including how results are communicated, assessment for the examination itself, and the communication and dignity discipline of a personal, sometimes frightening procedure performed well.
How to study it. Risk-factor and education items expanded in the 2025 specifications: study the additions deliberately rather than from an older outline’s habits. Beyond the method in that note, work this area in two passes: a knowledge pass that closes gaps in the underlying material, and an item pass under time, because the guide’s recurring finding across credentials is that candidates know more than their timed performance shows. Keep an error log keyed to this area’s subtopics; the log, reviewed weekly, is what converts practice volume into score movement. When an error repeats, the fault is a concept, not an item — return to the primary published outline for that subtopic and rebuild the concept before attempting further items in it.
Image Production — 30 scored questions
Image acquisition and quality assurance: mammographic equipment and detectors, digital acquisition and image processing, exposure and dose discipline, quality control testing and its records, artefact recognition, and the MQSA equipment and quality standards — now including breast density reporting requirements, added to this category in the 2025 specifications.
How to study it. QC is examined as a schedule with actions attached: learn each test’s frequency, its limits, and the response a failure demands. Beyond the method in that note, work this area in two passes: a knowledge pass that closes gaps in the underlying material, and an item pass under time, because the guide’s recurring finding across credentials is that candidates know more than their timed performance shows. Keep an error log keyed to this area’s subtopics; the log, reviewed weekly, is what converts practice volume into score movement. When an error repeats, the fault is a concept, not an item — return to the primary published outline for that subtopic and rebuild the concept before attempting further items in it.
Anatomy, Physiology, and Pathology — 26 scored questions (within Procedures)
The breast itself: anatomy and physiology across the lifespan, benign and malignant pathology, the imaging appearance of disease, and the clinical reasoning that connects a finding to the next view, the next modality, or the biopsy suite.
How to study it. Pathology items pair appearance with action — study each entity as image, differential, and disposition together. Beyond the method in that note, work this area in two passes: a knowledge pass that closes gaps in the underlying material, and an item pass under time, because the guide’s recurring finding across credentials is that candidates know more than their timed performance shows. Keep an error log keyed to this area’s subtopics; the log, reviewed weekly, is what converts practice volume into score movement. When an error repeats, the fault is a concept, not an item — return to the primary published outline for that subtopic and rebuild the concept before attempting further items in it.
Mammographic Positioning and Imaging Procedures — 39 scored questions (within Procedures)
The largest single block in the examination and the craft’s core: standard screening projections, diagnostic work-up views, magnification and spot compression, imaging of the augmented, reconstructed, and male breast, special-needs positioning, and the evaluation criteria by which each image is judged adequate or repeated.
How to study it. Positioning is examined as criteria, not choreography: for every view, learn what must be included, what must be excluded, and the named errors that fail the image. Beyond the method in that note, work this area in two passes: a knowledge pass that closes gaps in the underlying material, and an item pass under time, because the guide’s recurring finding across credentials is that candidates know more than their timed performance shows. Keep an error log keyed to this area’s subtopics; the log, reviewed weekly, is what converts practice volume into score movement. When an error repeats, the fault is a concept, not an item — return to the primary published outline for that subtopic and rebuild the concept before attempting further items in it.
How is the Mammography examination scored?
ARRT reports post-primary examination performance as a scaled score from 1 to 99, and 75 is the passing standard for the Mammography examination as for ARRT’s examinations generally. The scaled score is a transformation, not a tally: raw performance is equated across examination forms so that the standard represents the same competence whichever form a candidate draws, and 75 must never be read as 75 percent of items correct. Of the 145 items presented, 115 are scored and 30 are pilot questions being evaluated for future forms; pilots are unidentified, distributed through the sitting, and — under the specifications effective September 1, 2025 — increased in number from the previous form’s 25, a change ARRT published with the current specifications. The preparation consequence is the usual one, sharpened: there is no identifiable soft section to coast through, and the scored weight sits where the specifications put it — more than half in Procedures — so a study plan balanced evenly across the three categories is already misweighted.
What makes this examination demanding?
It examines a craft at the point where positioning, physics, regulation, and patient experience intersect — and it weights the intersection honestly. Sixty-five of 115 scored questions are Procedures, and within them positioning is judged by criteria: the candidate must know not only how a view is taken but how it is evaluated, what its named failures are, and what the next action is when tissue is missed. Image Production examines a quality system, not a machine tour — QC schedules, dose discipline, and MQSA requirements with density reporting newly added. Patient Care examines risk and communication in a screening population that is mostly well and occasionally terrified. Candidates arriving from general radiography own the radiation science and must build the breast-specific craft; the examination assumes the supporting credential and spends nothing re-testing it.
Application order, and why the examination comes last
ARRT’s post-primary design makes the examination deliberately the final step, and the application system enforces the order: structured education logged and complete, clinical experience logged and complete, ethics standing confirmed, supporting Radiography credential current — then the examination application, then scheduling at Pearson VUE inside the appointment structure the handbook sets (two and a half hours of testing inside a 170-minute appointment). Candidates should treat the two pre-examination legs as the schedule’s long poles. Structured education must fall inside the 24 months before application, so education taken too early expires out of the window while clinical experience is still accumulating; the efficient sequence runs the clinical log first or in parallel, and places the 16 structured hours late enough to sit comfortably inside the window at application. The clinical leg has its own pacing law — the 16-entries-per-day cap and a procedure mix spanning screening, diagnostic, and quality work — which together mean it is measured in months of ordinary departmental work. Both legs are logged through ARRT’s online post-primary tool as they are completed; the tool’s record, not a personal spreadsheet, is what the application will read, so entries belong there contemporaneously. ARRT publishes the current application and examination fees in its pathway handbook and application system; confirm the figures there when you apply rather than from any guide, this one included — fee lines are exactly the kind of fact a preparation page should send you to the primary source for when it cannot pin them itself.
Holding the credential: renewal, CE, and the MQSA parallel
ARRT certification is maintained, not merely held: annual renewal, continuing education on ARRT’s published biennial cycle, and continuing compliance with the Standards of Ethics keep both the supporting Radiography credential and the Mammography credential built on it in force. Alongside ARRT’s system runs MQSA’s: federal personnel standards for mammography — initial training, continuing experience, and continuing education as the federal rules set them — enforced through facility accreditation and inspection. The two systems overlap without containing each other, and the practising mammographer lives in both: an employer audits MQSA currency for the facility’s sake and ARRT currency for the credential’s. The study habit this examination rewards — criteria kept current against the controlling document, whether that document is the 2025 content specifications or the MQSA regulations — is the same habit the credential’s working life demands, which is the deepest sense in which this post-primary examination is a fair test of the practice it certifies.
A closing note on rehearsal realism: because candidates for this examination are working technologists, rehearsal sittings should be scheduled as work is scheduled — protected, timed, and not fragmented across a shift’s leftovers. Two honest full-length rehearsals teach more about this sitting’s pacing than six interrupted ones.
A study plan proportioned to the sitting
Build the plan backward from a target sitting, and build it on the outline’s weights rather than on the order of a textbook. The first phase is diagnostic: a timed, mixed set across all areas, scored by area, whose only job is to locate you — most candidates discover that their strongest work area is not their strongest examination area, and the plan must be built on the second list. The second phase is area work in weight order, largest first, using the methods set out in the outline sections above, with the error log running throughout. The third phase is integration: full timed rehearsals at the real sitting’s length and pace, taken under examination conditions — no pauses, no references, no phone — with each rehearsal mined for two outputs only, the pacing faults and the repeating concepts. Reserve the final days for the repeating concepts and for logistics: identification, location or remote-proctoring setup, and the body’s published examination-day rules. Candidates who are also completing eligibility steps — documentation, clinical logs, pathway verification — should run those on a parallel calendar from the first week; eligibility delays, not knowledge gaps, are the most common reason a prepared candidate misses a target window.
One structural warning belongs in every plan for this examination: preparation materials age. Outlines are revised, fees and windows change, and a plan built on a superseded document trains for an examination that no longer exists. The facts in this guide are pinned to the sources in its internal section as of its drafting; confirm the outline edition and the application calendar against the body’s current publications when your plan begins, and again before you apply.
What the companion program adds
When enrollment opens, the PassProfessor program for this examination will carry the practice this guide plans around: original items written to the published outline at its weights, timed sets at the real sitting’s shape, results readable area by area, and the credentialing route carried alongside the practice so the examination stays a means to the credential it serves. Until then, this guide stands on its own as the route and outline reference for the examination, and the notify list is the way to hear when the program opens.
Frequently asked questions
Can I earn ARRT Mammography as my first credential?
No. Mammography is a post-primary credential. You must first hold ARRT certification and registration in Radiography, then complete the structured education and clinical experience requirements, then pass the Mammography examination.
How many questions are on the Mammography examination?
145 items in two and a half hours: 115 scored questions and 30 unscored pilot questions, under the content specifications effective September 1, 2025.
What score passes?
A scaled score of 75 on ARRT’s 1-to-99 scale. It is an equated scaled score, not 75 percent of items correct.
What are the content categories?
Patient Care (20 scored questions), Image Production (30), and Procedures (65) — with Procedures divided between Anatomy, Physiology, and Pathology (26) and Mammographic Positioning and Imaging Procedures (39).
How much structured education is required?
At least 16 hours mapped to ARRT’s specified Mammography content areas, with credit in each required area, completed within the 24 months before you apply.
What clinical experience is required?
Documented mammographic imaging on 75 patients across ARRT’s required and elective procedure set, logged through ARRT’s post-primary tool, with a maximum of 16 entries per day.
How should the clinical-experience leg be scheduled?
Against the 16-entries-per-day cap and the procedure mix, not against enthusiasm: the required and elective set spans screening and diagnostic work and quality procedures, so the log fills at the pace the department’s case mix allows. Start the log early in the study plan; it is the leg candidates most often discover too late.
Which 2025 change matters most to a candidate who studied an older outline?
Breast density reporting under MQSA in Image Production, and the Patient Care additions — results communication and risk factors. Both are examinable precisely because they are new; a superseded outline leaves them at zero.
Why are there 30 pilot questions?
ARRT evaluates future examination content by embedding unidentified pilot items in live forms; the 2025 specifications raised their number from 25 to 30 while the scored total held at 115. Pilots cannot be identified or skipped strategically — answer everything at full effort.
How does structured education differ from ordinary continuing education?
Structured education must map to the content categories ARRT specifies for this credential, with the category minimums the requirements set, inside the 24-month window. General CE hours that do not map do not count, however relevant they feel — choose activities against ARRT’s category table first.
What changed in the September 2025 specifications?
ARRT adjusted the question distribution (scored total unchanged at 115), raised pilot questions from 25 to 30, added patient-education content on receiving results and detail on risk factors in Patient Care, and added breast density reporting requirements under MQSA in Image Production.
Is ARRT certification the same as MQSA qualification?
No. MQSA is federal law governing mammography facilities and personnel, enforced by inspection; ARRT certification is a professional credential. They run in parallel and both matter to practice — neither substitutes for the other.
Does my Radiography credential need to stay current?
Yes. The post-primary credential rests on the supporting credential and on continuing compliance with the ARRT Standards of Ethics, and ARRT certification is maintained through annual renewal and continuing education under ARRT’s published rules.
Is PassProfessor affiliated with ARRT?
No. PassProfessor is an independent preparation provider, not affiliated with the American Registry of Radiologic Technologists. The program confers no certification and reports nothing to ARRT.
