The Limited Scope of Practice in Radiography examination is
administered on behalf of state licensing agencies to assess the knowledge and
skills of radiography candidates by the American Registry of Radiologic
ARRT offers credentialing covering the practice of
radiologic technology. Thirty-nine states require credentialing as a part of
their licensing program. ARRT certification and state licensing have separate
To be eligible for the exam, you must meet the entity requirements of the state you wish to take the exam in.
Scheduling your exam
Once your application is approved, ARRT sends a candidate status report
(CSR) with instructions you need to schedule your exam. You have 90 days from the
date of receipt of your CSR to schedule your exam.
Exams are offered at Pearson VUE test centers located nationwide and
are available on an appointment basis Monday through Friday. Some centers have
Saturday appointments available.
The exam is computer-delivered consisting of multiple-choice questions.
The exam contains a core module and procedure modules. Every
candidate completes the core module, and your
state determines which procedure modules you will complete.
The Core Module consists of 115 questions covering the following:
- Patient Interactions and Management
- Radiation Physics and Radiobiology
- Radiation Protection
- Image Acquisition and Evaluation
- Equipment Operation and Quality Assurance
- Image Production
The Procedure Modules consist of 20-25 multiple-choice questions each.
Your raw score is converted to a scaled score. The scaled score ensures
consistency in grading the exam, regardless of the difficulty of the exam. To
pass both the Core Module and the Procedure Modules, you need to obtain a
scaled score of 75.
Arrive early for your testing appointment and be prepared with the
required identification. Additional security measures may be in place including
palm vein scanning, digital signature, and a digital photograph. You are not
allowed to bring any resources, scratch paper, calculators, or writing utensils
with you. All the supplies you need for the exam are provided.
At your testing station, you have an opportunity to take a short
tutorial. After the tutorial, your exam begins. The test proctor provides an erasable
note pad and dry-erase pen for notetaking. You cannot take the note pad out of
the testing center. An onscreen computer and reference sheets are available for
your use during the exam.
Each question must be answered before the computer allows you to move
on to the next question. You are able to mark items for review. After you have responded
to all the questions and time remains, you are provided an opportunity to
review your work. Once you have reached the allotted time, your exam closes,
and your responses are sent to be evaluated and graded. The required modules
will appear one after the other until the state-required modules are completed.
Each correct answer is tallied to come up with your raw score. The raw
score is converted to a scaled score with a range of one to 99. Each state
determines the passing score, but an average passing scaled score is 75.
You will not receive a score report at the end of your exam at the test center. The results are sent directly to your state licensing board, which determines your pass or fail status. Within four weeks of taking the examination, your state licensing board will notify you of your pass or fail status. Any questions regarding your score report are directed to your licensing board, not ARRT.
How Can I Prepare for the Limited Scope of Practice in Radiography Test?
That’s a great question. We’ve broken down the answer into three parts.
- Do yourself a favor and study. Do not walk in unprepared. We have recommended prep materials below, but that only helps if you actually try. Plus, studying is actually proven to be the best antidote to test anxiety.
- Take care of yourself. Make sure you’re eating well, exercising, and sleeping. All of these things are scientifically linked to brain performance. If you take care of your body, you’ll be helping your grades.
- Get a study guide or set of flashcards. Some people study better a certain way. Find your study strengths and make the most of them. We’ve tried to make it easy for you by tracking down the best study guide and flashcard set for your exam. Below you’ll see links to both!
