After you take an exam, you’ll receive a preliminary scaled score at the test center. This isn’t your final score.

Within four weeks of your exam, we’ll mail you an Examination Results Packet, which contains your official score report and your certification and registration results. Your score report will reveal your total score and show your relative performance by content area. You can use this valuable information in designing your own continuing education program or for guidance in studying should you need to retake the exam. 

If needed, you can request a Duplicate Examination Results Packet or a Duplicate Examination Score Report.

If we find that you provided inaccurate or incomplete information or didn’t pay all appropriate fees, we may cancel your exam score or hold the results for as long as six months after the exam. If we find you ineligible for certification and registration, or if an issue remains unresolved after six months, we’ll cancel your score. In that case, you’ll need to schedule a new exam if you're eligible. 


At ARRT, we constantly update exams—adding new questions and removing outdated ones to address advances in the profession. Several versions of each exam might exist at any given time.

We keep a close eye on the results of our exams. We even track the results of each individual test question. Sometimes, statistics show that one exam is slightly “easier” than other versions. To make our exams fair and equitable to all, we use a system called scaled scoring. The equation underlying this method addresses any differences in difficulty across versions of each exam.

Our exam scoring scale ranges from 1 to 99, and you’ll need a total score of 75 to pass the exam. This isn’t a percentage; the number of correct answers necessary to obtain a scaled score of 75 will always vary. For example, each discipline has a different number of questions on its exams. On some exam versions, you might need to correctly answer 131 of 200 questions to receive a scaled score of 75. On more “difficult” exam versions, you might need only to answer 130 of 200 questions correctly to receive a 75 scaled score. Research supports the concept of scaled scoring, and the method meets or exceeds industry testing standards to keep our exam scores fair over time.   


When we calculate exam results, we start by determining how many questions you answered correctly. Then we assign a scaled score. A scaled score of 75 or above is passing.

Next we calculate the scaled scores for the individual sections of your exams. We do this entirely for your benefit, so you can see your relative performance across content sections. 

Averaging your section scores doesn’t equal your total score. Because each section has a different number of questions, we “weight” section scores. We place more weight on a section with 75 questions than we do on a section with only 35 questions.


One exception occurs with our Sonography exam. The total weighted score alone doesn’t determine whether you pass or fail the exam. You must obtain a scaled score of 75 on the overall exam and scaled section scores of 7.5 on two specific individual sections: abdomen and OB-GYN.


ARRT uses several quality-control procedures to ensure that all exams are scored with complete accuracy. It’s extremely unlikely that our scoring calculations will be incorrect. For a fee and within a certain amount of time, however, you may request a review of your score’s accuracy if you think a calculation error has occurred. Check your handbook for instructions and more information.
