What is the ARRT?

The American Registry of Radiologic Technologists is a credentialing organization that helps qualify new professionals for work in radiation therapy, medical imaging and interventional procedures. ARRT certification is frequently required for jobs in these fields. The exams offered by ARRT challenge entry-level technologists on their knowledge of the daily tasks necessary for the profession. With a passing score, new technologists can find career opportunities across the country.

Which ARRT Should I Take?

Keep your professional goals in mind when determining which ARRT certification to pursue. If you're hoping for a career in cancer detection, for instance, you may want to take the ARRT mammography exam. Those interested in sonography, on the other hand, may want to register for the ARRT vascular exam, where they'll be challenged on their knowledge of ultrasound equipment. Knowing which ARRT test to take is truly up to you.

Before you register, though, you'll want to confirm your eligibility. Only those who have completed the necessary coursework related to their field of professional practice should sign up for ARRT certification tests. An associate degree or higher is required for most ARRT exams.

Other ARRT tests include:

  • ARRT Bone Densitometry
  • ARRT Cardiac-Interventional Radiography
  • ARRT Computed Tomography
  • ARRT Limited Scope of Practice in Radiography
  • ARRT Magnetic Resonance Imaging
  • ARRT Mammography
  • ARRT Radiography
  • ARRT Registered Radiologist Assistant
  • ARRT Sonography
  • ARRT Vascular-Interventional Radiography

How to register for the ARRT

Whether you're hoping to take the ARRT MRI, ARRT ultrasound exam,or the ARRT radiography exam, you'll first need to apply with the certification body. Upon completion of an ARRT-approved educational program, you'll need to ask your Program Director for an application. Complete and sign it, then ask your Program Director to fill out their portion of the form. Next, mail in the completed application. ARRT will verify the information and give you the okay to schedule and take your ARRT certification test.

It's critically important that you complete your education before registering. Since so much of the ARRT exam content centers around what you've learned in the classroom, you'll find it nearly impossible to pass without finishing your education first. Registration is linked directly with your program of study, too, making it difficult to even sign up for the test without first completing your studies.

How Does ARRT Scoring Work?

ARRT test results will become available within a few weeks of testing. A thorough score report will be mailed to you, detailing which questions you got wrong and why. Should you need to retake the ARRT certification exam, this information will be extra helpful.

ARRT exam content is scored on a scale of one to 99. In order to pass, you'll need to earn at least a 75 or higher. This score is not a percentage. The number of correct answers you'll need to get a 75 will vary from test to test. For instance, if you answer 131 out of 200 ARRT exam questions correctly, you'll earn a 75. On more difficult versions of ARRT certification tests, you might only need to answer 130 questions right to earn a 75. While it might sound confusing at first, scaled scores help keep things fair.

When your ARRT certification test results are calculated, the number of correct answers are counted first. Next, the scaled scores for individual sections of the test are scored. This helps show your performance across content areas. Averaging your section scores doesn't give you your final score, though. Instead, ARRT exam content is weighed individually. It all combines to give you a score that's representative of what you really know.

How to Prepare for ARRT Subject Assessment Tests

ARRT certification exams shouldn't be undertaken lightly. Your score can dictate your first few years of your career, so you should aim to score as high as possible on your first attempt. While retakes are possible, they can be time-consuming and expensive. Earn a high score on your first attempt and you'll be on your way to your new profession.

Your ARRT study material should include some form of practice testing. Research shows that it's one of the most effective forms of test prep. Begin your MRI ARRT test prep efforts – or your studies for any of the ARRT tests – with a practice test. The results can help you craft the most effective study plan possible, ensuring you make the most out of your time.

An ARRT practice exam can identify content area blind spots, giving you unique insight into which areas merit further study. While you might think you've mastered CAT scan procedures or the log rolling method, your performance on a practice test may prove otherwise. When it comes time to prepare for a certification exam for your career, there's nothing more valuable than this kind of foresight.
