How to Prepare for the ARRT Radiography Exam

The ARRT Radiography exam is the milestone every radiography student works toward. It tests what you learned across your entire program — anatomy, positioning, physics, patient care, image production, and radiation safety — in one sitting.

It’s a big exam. But it’s also very passable if you prepare the right way. Here’s what actually works.

Start earlier than you think you need to

Most students underestimate how much review the ARRT requires. The exam covers material from your entire program, so even topics you did well on in class will need refreshing.

Give yourself at least 8 to 12 weeks of consistent review before your test date. Cramming in the final two weeks doesn’t work for an exam this broad. An hour a day for ten weeks beats ten hours a day for the last week, every time.

Know what the exam actually covers

The ARRT publishes a content outline for the Radiography exam. It’s broken into major sections, and each section is weighted. Some topics appear more than others.

Print the content specification, highlight the high-weight areas, and use it as your study roadmap. If you’re spending most of your time on low-weight topics, you’re leaving points on the table.

The broad areas include:

Patient care and education — patient interactions, communication, consent, and safety
Safety — radiation protection for patients, personnel, and the public
Image production — equipment, physics, technique, and image quality
Procedures — positioning, anatomy, and patient care
Image evaluation — recognizing quality issues and knowing what to do about them

Every question you’ll see maps back to one of these areas.

Build a study plan you’ll actually follow

The students who pass on the first try share one habit: they study consistently and intensely.

A simple structure that works:

Divide your review by content section. Give each section a week or two depending on its weight.
Use a mix of formats. Read, watch videos, do practice questions, and teach concepts out loud to yourself.
Take a full practice exam every two weeks. These tell you where you actually stand, not where you think you stand.
Review what you got wrong. The questions you miss are the highest-value study material you have.

Don’t skip the physics

This is the section students avoid the most — and it’s the one that quietly costs them points.

Physics and image production make up a meaningful portion of the exam. You don’t need to become a physicist. You need to understand the relationships: how kVp affects contrast, how mAs affects density, how distance affects intensity, and how these interact.

If physics is your weak area, don’t save it for last. Front-load it so you have time to revisit it.

Practice questions are not optional

You cannot pass this exam by reading alone. You need to answer questions — hundreds of them — because the exam tests your ability to apply what you know, not just recall it.

Two rules for practice questions:

Do them under realistic conditions. Timed, no notes, no scrolling back.
Study every explanation, including for questions you got right. Sometimes you guessed correctly and didn’t know it.

The week before the exam

In the final week, don’t try to learn anything new. Your goal is to consolidate what you already know.

Review your notes on weak areas
Take one final practice exam two or three days out
Confirm your test-day logistics — location, ID requirements, arrival time
Sleep. Seriously. A rested brain outperforms a tired one every time.

Test day

On exam day, trust your preparation. A few practical reminders:

Read each question fully. Many mistakes happen because students miss a single word like “not” or “except.”
Answer every question. There’s no penalty for wrong answers on the ARRT.
Flag and move on. If a question stumps you, mark it, guess, and come back if you have time.
Use your full time if needed. There’s no prize for finishing early.

A final note

The ARRT Radiography exam is hard, but it’s not unfair. It tests exactly what your program taught you. If you review consistently, work through enough practice questions, and walk in rested, you’ll be fine.

If you’d like one-on-one help with your ARRT prep — reviewing weak areas, working through practice questions, or just staying accountable — book a tutoring session with a credentialed technologist.
