How to Study for the ARRT: What the Science Says
Most of what feels like studying barely works. Here are the evidence-based study methods that actually build durable knowledge for the ARRT Radiography exam — plus focus-block strategies and adaptations for ADHD.

A week-by-week ARRT Radiography study plan built around practice questions instead of reading hours — including what to do when you fall behind, how to read a mock exam score, and how to compress it if you are working clinicals.

The 15% Rule in Radiography, Explained
A 15% change in kVp does to receptor exposure what doubling or halving the mAs does — but the rule is range-dependent, and most explanations leave that out. The arithmetic, the worked examples, and the kVp-squared trap the registry tests.
Read guide · 7 min →kVp vs mAs: What Each One Actually Controls
mAs is how many x-ray photons you make; kVp is how hard they hit. Which one controls contrast, which one controls noise, why neither substitutes for penetration, and how to tell from a question stem which one it wants.

ARRT Radiation Safety Study Guide
Safety is 50 of the 200 scored questions, and radiation physics lives here rather than in Image Production. What is tested, the dose limits and regulatory numbers to memorize cold, and the distinctions that get asked directly.
Read guide · 8 min →ARRT Image Production Study Guide
Image Production is 51 of the 200 scored questions and half of it is equipment, not technique. The factor-effect table worth memorizing blank, the digital-imaging habits to unlearn, and the equipment half most students skip.

Procedures is the largest category at 66 of the 200 scored questions, with Extremity the biggest block. How to decode any projection name, the cervical-versus-lumbar oblique inversion that costs students points, and the central-ray angles to memorize.
