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.

Mammography is the most regulated room in radiologic technology. It is the one imaging discipline governed by its own federal statute — the Mammography Quality Standards Act — with facility accreditation, personnel standards, and equipment requirements enforced through inspection, layered on top of the craft itself: positioning that decides whether tissue is imaged or missed, compression that patients remember, and image quality on which early cancer detection literally depends. ARRT’s Mammography credential is a post-primary certification: it does not start a career in imaging, it specialises one, and its route is deliberately three-legged — structured education, documented clinical experience, and examination — before the letters are granted.
PassProfessor’s ARRT Mammography program is in the works as part of the expanding PassProfessor catalog, built on ARRT’s Examination Content Specifications for Mammography effective September 1, 2025. This page records the post-primary structure honestly — who may pursue it, what the education and clinical legs require, how the examination is built and scored — and how the program in the works will be shaped. Everything factual comes from ARRT’s published pathway handbook and content specifications, recorded in this file’s internal sources section.
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.

What the examination covers
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.
Risk-factor and education items expanded in the 2025 specifications: study the additions deliberately rather than from an older outline’s habits.
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.
QC is examined as a schedule with actions attached: learn each test’s frequency, its limits, and the response a failure demands.
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.
Pathology items pair appearance with action — study each entity as image, differential, and disposition together.
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.
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.
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.
Who may sit — eligibility in full
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.
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.
What the PassProfessor program will cover
Written to the September 2025 specifications. Practice is being built from ARRT’s Examination Content Specifications for Mammography effective September 1, 2025 — including their published changes: the added patient-education and risk-factor content, breast density reporting under MQSA, and the 30-pilot form. No practice item is an actual examination item, a recalled item, or another provider’s material, and no item is built to a superseded outline.
Positioning criteria at the centre. The largest scored block gets the largest practice share: view-by-view evaluation criteria, inclusion and exclusion standards, and failure recognition, alongside pathology’s image-and-disposition pairings.
Timed practice at the real sitting’s shape. 145 items in two and a half hours. The program’s design includes timed sets modelled on that sitting, because post-primary candidates — working technologists, studying around shifts — need pacing rehearsed, not assumed.
The whole post-primary route, mapped. Around the item practice, the program carries the route as ARRT publishes it: the Radiography prerequisite, the 16-hour structured education leg and its 24-month window, the 75-patient clinical leg and its daily logging cap, MQSA’s parallel frame, and scaled scoring at 75.
Preparation only. This is preparation for an examination administered by the American Registry of Radiologic Technologists (ARRT). PassProfessor is independent and is not affiliated with ARRT; no completion of this program is reported to the credentialing body, and nothing in the program substitutes for any step in the credentialing process.

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.
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.
