What is the Radiography Exam?
Why the Radiography is Challenging
The Radiography is often considered one of the more challenging exams because:
- Breadth of content: The exam spans four very different content areas — from HIPAA and infection control, to x-ray physics and radiation protection, to positioning for dozens of anatomic regions
- Procedures carries the most weight: At 66 of 200 scored questions (33%), Procedures — positioning, anatomy, and pathology for the head, spine, thorax, abdomen, and extremities — is the single largest content category
- Time pressure: ARRT allows approximately one minute per question, so you need to move efficiently through 230 total items
- High stakes: You have only three attempts within three years to pass before you have to requalify by repeating your educational program

Answer Key with Explanations
HIPAA establishes national standards for protecting patient health information, including who can access records and how information may be shared. The Patient Self-Determination Act concerns advance directives, and OSHA's Bloodborne Pathogens Standard addresses occupational exposure to blood, not confidentiality.
Airborne precautions (used for diseases like tuberculosis, measles, and varicella) require a fit-tested N95 respirator or higher, because the pathogen travels on small airborne particles that a standard surgical mask doesn't filter effectively. Gloves and gowns address contact risks, not airborne transmission.
The three cardinal principles of radiation protection are minimizing time spent in the radiation field, maximizing distance from the source, and using shielding when time and distance can't sufficiently reduce exposure. Filtration and collimation are important dose-reduction tools, but they aren't the three cardinal principles.
In the photoelectric effect, the incident photon is completely absorbed by an inner-shell electron, depositing all of its energy in the patient's tissue. This makes it the dominant contributor to patient absorbed dose at diagnostic energies, while Compton scattering primarily contributes to scatter radiation and occupational exposure. Pair production doesn't occur at diagnostic x-ray energies.
Filtration removes low-energy ('soft') photons from the beam before they reach the patient. These photons would otherwise be absorbed entirely by the patient's tissue, adding to dose without ever reaching the image receptor. Narrowing the field of view is the job of beam restriction (collimation), not filtration.
mAs (milliampere-seconds) controls the quantity of x-rays produced and has a direct, proportional relationship with radiographic density/receptor exposure, with little effect on beam penetration or contrast. kVp primarily affects penetration and contrast; SID affects both density and magnification; focal spot size primarily affects spatial resolution.
Digital image processing can compensate for a wide range of exposures, so an image can look acceptable even when the patient was overexposed. A higher-than-expected exposure indicator signals that more radiation reached the receptor than necessary — a key reason radiographers must monitor exposure indicators rather than judging exposure by image appearance alone.
In an anterior oblique position, the patient faces the image receptor. 'Left anterior oblique' means the body is rotated so the left anterior portion of the torso is closest to the image receptor. A right anterior oblique (RAO) would place the right anterior torso closest to the receptor instead.
The cross-table (horizontal beam) lateral cervical spine projection is performed with a horizontal x-ray beam and a vertically placed image receptor, allowing the radiographer to image the cervical spine without moving a trauma patient whose spine hasn't yet been cleared. The other projections listed typically require patient movement that isn't safe until the spine is cleared.
In the PA projection, the heart is closer to the image receptor, which minimizes magnification and gives a more accurate assessment of cardiac size and mediastinal structures. The AP projection, with the heart farther from the receptor, magnifies the cardiac silhouette. AP chest projections are reserved for patients who can't stand or tolerate the PA position.

Radiography Exam Scoring & Pass Rate
Current Pass Rates
According to official data, the Radiography first-time pass rate is approximately 85.8%. This makes it one of the more challenging exams.
Why Pass Rates May Be Lower
- Procedures is the largest category: Positioning, anatomy, and pathology across the head, spine, thorax, abdomen, and extremities make up 33% of the exam (66 of 200 scored questions)
- Image-based questions: Many Procedures and Image Production questions ask you to identify anatomy or positioning/exposure errors directly from a radiographic image
- Physics and clinical knowledge combined: Safety and Image Production together make up over half the exam (50.5%) and require comfort with x-ray physics, equipment, and quality control — not just clinical positioning
- Time pressure: With approximately one minute per question, you can't afford to get stuck
Understanding Your Score Report
Your score report includes:
- Overall scaled score (1–99 scale; 75 or higher is passing)
- Section-by-section performance breakdown by content category
- A secure link you can use to share your score report with employers or schools
What If You Don't Pass?
First, know that you're not alone—many examinees don't pass on their first attempt.
- Waiting period: None (3 attempts total within 3 years of your first exam window) before you can retake
- Re-application: You must submit a new application and fee for each attempt
How to Register for the Radiography Exam
Step 1: Create an ARRT Account
Visit arrt.org and create an account. Your educational program director will typically help set this up and will approve your account once you're ready to apply.
Step 2: Meet the Education Requirements
ARRT offers two eligibility pathways for Radiography:
- Primary Pathway: Complete an ARRT-recognized, accredited radiography educational program and earn an associate degree or higher from an accredited institution
- Postprimary Pathway: Already hold an eligible ARRT (or equivalent) credential and complete a postprimary radiography education program
Step 3: Address Ethics Requirements
Comply with the ARRT Standards of Ethics. Your application will ask ethics questions covering criminal charges and convictions, and you must report any violation within 30 calendar days of when it occurs. If you're concerned about a past issue, you can submit an optional Ethics Review Preapplication (a $100 nonrefundable fee) before you apply.
Step 4: Submit Your Application and Pay the Fee
Log in to your ARRT account, apply for the Radiography credential, and pay the $225 primary-pathway application fee. ARRT generally needs at least 30 calendar days to process your application; once approved, you'll receive a Candidate Status Report and a one-year exam window.
Step 5: Schedule with Pearson VUE
Starting 24 hours after you receive your Candidate Status Report, schedule your exam at one of Pearson VUE's 200+ U.S. test centers (also available in select Canadian, European, Asian, and Australian cities) — either online at home.pearsonvue.com/arrt or by phone.
What to Expect on Exam Day
For In-Person Testing
Before arrival:
- Get a full night's sleep and eat a balanced meal beforehand
- Arrive at least 30 minutes before your scheduled appointment
- Bring two forms of valid, unexpired ID: a government-issued primary ID with your printed name, photo, and signature (such as a driver's license, state ID, passport, or military ID), plus a secondary ID with your printed name and signature
At the testing center:
- Store all personal items — including your phone, watch, and any notes — in a secure locker before entering the test room; you won't have access to them again until you finish (or, for the Sonography exam only, during its scheduled break)
- Sign a digital signature pad at check-in
- Don't bring your own calculator — Pearson provides an onscreen basic and scientific calculator you can use during the exam
During the exam:
- You'll get an 8-minute tutorial and 2 minutes to accept the nondisclosure agreement before your test time starts
- You must answer each question before the computer lets you move on — flag questions you're unsure of and return to them if you have time left
- Raise your hand if you need help; staff can bring you a handheld calculator, earplugs, or noise-reducing headphones, but don't leave the test center building before you finish your exam
For Online Proctoring
System requirements:
- ARRT does not currently offer online or at-home proctoring for the Radiography certification exam. Unlike ARRT's CQR Structured Self-Assessment (a separate, later renewal requirement), the Radiography exam is administered only in person at Pearson VUE test centers
- Pearson operates more than 200 high-security test centers across the U.S. and its territories, plus additional locations in select Canadian, European, Asian, and Australian cities
Environment requirements:
- Since there's no online option for this exam, plan on an in-person appointment — see the in-person requirements above; they apply to every Radiography exam appointment
- If you need ADA testing accommodations, request them when you apply; approved accommodations can affect how and where you test and may require extra processing time
How Long Should You Study?
The ideal study timeline depends on your background:
| Situation | Recommended Study Time |
|---|---|
| Recent graduate, currently finishing clinicals | 4-6 weeks |
| Recent graduate (< 6 months out) | 6-8 weeks |
| Working limited-scope or student technologist | 8-10 weeks |

Tips to Pass the Radiography Exam
1. Prioritize Procedures
Procedures makes up 33% of the exam (66 of 200 scored questions) — more than any other category. Make sure you can identify correct positioning, common positioning errors, and relevant anatomy for every body region in the content specifications.
2. Don't Neglect Safety and Physics
Safety (25%) and Image Production (25.5%) combine for over half the exam. Understand the reasoning behind exposure factors and radiation protection instead of just memorizing rules.
3. Practice Under Real Conditions
Complete a full 230-question mock exam in one sitting. ARRT allows approximately one minute per question, so build the habit of moving efficiently and flagging questions you're unsure of instead of getting stuck.
4. Study With Images
Many Procedures and Image Production questions show you a radiograph and ask you to identify anatomy, positioning, or exposure errors. Practice with labeled anatomy images, not just text-based flashcards.
5. Focus on Your Weak Categories
After each practice test, calculate your accuracy by content category and spend the majority of your remaining study time on your lowest-scoring areas.
6. Know Your Exam-Day Logistics Ahead of Time
Confirm your two forms of ID, plan to arrive 30 minutes early, and remember you can't bring your own calculator, notes, or phone into the test room. Handling logistics ahead of time means one less thing to think about on exam day.
