If you’re preparing for the ARRT Radiography (RAD) exam, you’re probably juggling three big questions:

  1. What’s on the ARRT RAD exam?
  2. How does exam scoring work?
  3. How to study for the Radiology exam without wasting time.

This guide walks you through the exam format, key content areas, eligibility basics, a practical study plan, exam-day logistics, and the most common mistakes that cost candidates points.

Quick navigation

Fast facts (time, questions, scoring)

Is the ARRT Radiography exam computer-based?

Yes. ARRT exams are delivered at testing centers (commonly via Pearson VUE). You’ll complete a tutorial and agree to a nondisclosure agreement (NDA) before the exam begins, and you may also see a post-exam survey.

How many questions are on the ARRT RAD exam, and how long is it?

Expect a long, stamina-based exam. The Radiography test includes scored items plus “pilot” (unscored) items that are mixed in and not identifiable as unscored. ARRT explains that pilot items appear randomly and do not count toward your score, but they help develop future exams.

Helpful official starting points:

What’s the passing score?

ARRT uses a scaled score from 1 to 99. A score of 75 is required to pass (it is not a percentage).

Eligibility and requirements

ARRT certification and registration require meeting three pillars: education, ethics, and examination. For Radiography, you typically pursue this through ARRT’s primary eligibility pathway.

Education requirements (what candidates usually need)

  • An associate degree or higher (degree subject may vary by pathway details)
  • Completion of an ARRT-verified educational program in Radiography (or an acceptable equivalent pathway as defined by ARRT)

Ethics requirements (don’t skip this)

ARRT’s ethics requirements can affect eligibility, especially if you have past charges, convictions, or disciplinary actions. If you’re unsure whether something must be reported, use ARRT’s ethics resources and consider an ethics preapplication (when appropriate) so you don’t get surprised late in the process.

What’s on the ARRT Radiography exam

The most dependable way to study the right material is to follow ARRT’s official Examination Content Specifications (effective January 1, 2022). It’s designed from practice analysis data and maps to entry-level job tasks.

High-yield content buckets to plan around

Even without memorizing every bullet, most candidates benefit from organizing prep into a few recurring skill buckets:

  • Patient care (safety, comfort, communication, infection control, medical emergencies basics)
  • Safety, radiation protection, and radiobiology (ALARA mindset, shielding concepts, dose awareness, occupational safety)
  • Image production (exposure factors, contrast/spatial resolution, artifacts, digital image characteristics, quality control concepts)
  • Procedures and positioning (anatomy landmarks, projections, CR/IR placement, evaluation criteria, common errors)

How to use the content outline (the smart way)

  • Print the content specifications and highlight weak areas first.
  • Turn each subsection into a short checklist (can I explain this without notes?).
  • Pair every content topic with practice questions so you learn to apply it, not just recognize words.
  • Try studying with proven methods such as interleaving.

Scoring, passing score, and what 75 means

What does “scaled score” mean?

ARRT uses scaled scoring to account for differences in difficulty across exam versions. That’s why a “75” is not “75%.” The number of correct answers needed to earn a scaled 75 can vary depending on the specific version you receive.

What should you aim for on practice tests?

Because scaled scoring varies, don’t obsess over one magic percent. Instead, aim for consistent improvement, especially in your historically weakest category. A practical goal is “strong enough that a slightly tougher form won’t sink me.”

Study strategies and an 8-week plan

Most candidates do better with structured repetition than marathon cramming. Here’s an 8-week plan you can adapt (shorten to 6 weeks if you’re already knowledgeable about the content, extend to 10 to 12 if you’re starting from scratch).

Week 1 (Baseline and setup)

  • Take a diagnostic (mixed topics). Don’t study first.
  • Make a weakness list: by topic, not by question.
  • Create a study rhythm: 60 to 90 minutes/day, 5 to 6 days/week.

Weeks 2 to 3 (Build foundations)

  • Patient care + radiation protection fundamentals
  • Daily: 25 to 40 mixed questions + review explanations
  • Start an “error log” (why you missed it, what to remember next time)

Weeks 4 to 5 (Image production and quality)

  • Exposure factors, receptor exposure, contrast/spatial resolution tradeoffs
  • Digital imaging basics, artifacts, grid use concepts
  • Do short timed sets to build pace (10 to 20 questions at a time)

Weeks 6 to 7 (Procedures and positioning)

  • Prioritize common projections and evaluation criteria
  • Study mistakes by “pattern” (rotation, IR centering, tube angle, anatomy cutoff)
  • Mix in anatomy refreshers as needed

Week 8 (Final review and simulation)

  • 2 full-length practice exams (spaced several days apart)
  • Review only your top weaknesses (avoid trying to relearn everything)
  • Practice test-day routine (sleep, meal timing, break strategy)

How to use practice tests (without fooling yourself)

Rule 1: Review time matters more than test time

A 60-minute practice set with a 90-minute review beats a 3-hour test you never analyze. For every missed question, write:

  • What concept was tested?
  • What tempted me into the wrong answer?
  • What’s the “one sentence rule” I’ll use next time?

Rule 2: Mix topics early

The real exam is mixed. If you only practice in single-topic blocks, your brain gets “spoiled” by knowing what chapter you’re in. Use mixed sets at least 2 to 3 times per week.

Rule 3: Don’t memorize question banks

If you’ve repeated the same items, your score may rise while your understanding stays flat. Rotate sources, or use “new questions only” settings when possible.

Exam day logistics and what to bring

ARRT provides official guidance for what test day looks like, including rules at the test center, the environment, and what happens after you finish.

What to bring (typical essentials)

  • Valid, acceptable ID that matches your registration name (double-check your appointment confirmation)
  • Your test appointment details (digital or printed)
  • Comfort basics for the testing environment (light layers)
  • A light snack

When do you get results?

ARRT indicates you’ll receive an email when official results are available in your ARRT online account (commonly within about 10 business days).

Test day pacing tips

  • Don’t “camp” on one question. Make your best choice, flag it, move on.
  • Use breaks strategically to reset focus.
  • If you start rushing, slow down for 3 questions (read stem, underline key words mentally, eliminate 2 options).

Common pitfalls (and how to avoid them)

Pitfall 1: Studying only what feels comfortable

Comfort topics can become procrastination. Use your diagnostic and error log to force weak-area reps each week.

Pitfall 2: Memorizing “rules” without understanding tradeoffs

Image production is full of tradeoffs (contrast vs. exposure, motion vs. time, resolution vs. dose). Practice questions often test which tradeoff matters in the scenario.

Pitfall 3: Not practicing question interpretation

Many missed items are reading errors (left vs. right, best vs. first, most appropriate vs. acceptable). Train yourself to identify what the question is truly asking before you look at options.

Pitfall 4: Ignoring fatigue and timing

Stamina is a skill. If you only do short sets, your accuracy may drop late in the real exam. Add longer mixed sets in the final 2 to 3 weeks.

Retakes, attempt limits, and a comeback plan

How many times can you take the ARRT Radiography exam?

ARRT’s general rule is three attempts within three years for a certification and registration exam, with the three-year period tied to the starting date of your initial exam window.

If you fail, what should you do next?

  • Take 48 hours off (no doom-scrolling forums, no impulse buying new resources).
  • Review your performance report to identify the biggest gaps.
  • Rebuild your plan around the largest score gains first (usually weak categories + test-taking errors).
  • Do one full-length simulation before the retake (under realistic timing).
