Exam Format

You have three years and three attempts to pass ARRT’s R.T.(N) exam. It’s a computer-based test administered by Pearson VUE and includes 200 scored questions and 30 unscored questions. Most questions are multiple-choice with one correct answer. However, some might require selecting multiple answers from a list, sorting options into the correct order or selecting an image. Scored content includes the following number of questions in these categories:

• Patient Care: 24

• Safety: 25

• Image Production: 33

• Procedures: 118

You receive a preliminary score at the end of the exam that doesn’t indicate whether you passed or failed. Within 30 days, you receive an official score report in the mail from ARRT. The Verify Credentials page on ARRT will reflect your certification and registration status within approximately 4 weeks of completing your exam. 

ARRT uses a scaled scoring system, not raw scores. You must earn a scaled score of 75 or greater to pass. If you fail on your first or second attempt, a reapply button appears on your ARRT dashboard to allow you to apply to take the exam again. If you fail a third time, you’re no longer eligible to sit for the exam and receive details in your account on how to requalify.
