What a scaled score is
A raw score is the number of questions you answered correctly. ARRT converts it to a scaled score that takes into account the difficulty of each version of the exam, so a scaled score of 75 means the same level of performance on any version. ARRT's 2025 report gives about 67% correct as the approximate share needed to pass the radiography exam.
How the sections count
Your overall score comes from the total number of questions you answer correctly, not from your section scores. Section scores, from 0.1 to 9.9, show where you were stronger or weaker.
What to aim for in practice
- Take a full 230-question practice exam on the 230-minute clock.
- Find the areas where you get the fewest right and fix those first, starting with the ones that carry the most questions.
- Answer every question: your score counts correct answers, so a guess can only help.
