ExploreAbout this exam
The Registered Radiologist Assistant (R.R.A.) credential is an ARRT certification and registration for radiographers who have completed an additional, specialized educational program. According to ARRT, R.R.A.s are qualified to perform many procedures under a radiologist's supervision and provide advanced-level support to radiologists, with responsibilities that may include assessing and managing patients and performing select clinical procedures a radiologist would otherwise do. ARRT states that earning the credential requires, among other things, holding ARRT credentials in Radiography and completing an advanced educational program. Candidates should review ARRT's R.R.A. eligibility pathway, the Didactic and Clinical Portfolio Requirements, the Examination Content Specifications, and the Entry Level Clinical Activities list, and should begin with the R.R.A. eligibility pathway application handbook. This independent study guide organizes preparation into three domains: Patient Assessment and Management, Clinical Procedures, and Radiologic Imaging and Image Evaluation. Because ARRT's published material does not state the exam's question count, time limit, passing score, fee, retake policy, or credential validity, this page does not guess at those values; candidates should confirm them directly with ARRT. Use this material as a supplement to, not a substitute for, ARRT's own documents and your program's didactic and clinical curriculum.
What you'll study
About ARRT RRA preparation
Who is eligible to pursue the R.R.A. credential?
ARRT states that earning certification and registration as an R.R.A. requires, among other things, that you hold ARRT credentials in Radiography and complete an advanced educational program. ARRT directs candidates to its Registered Radiologist Assistant eligibility pathway and the R.R.A. eligibility pathway application handbook for the full requirements, including education, ethics, and examination.
What does the R.R.A. exam cover?
ARRT publishes Examination Content Specifications that cover the topics appearing on R.R.A. exams, plus an Entry Level Clinical Activities list of the core activities an individual should be qualified to perform at entry into the role. This study guide groups preparation into Patient Assessment and Management, Clinical Procedures, and Radiologic Imaging and Image Evaluation.
How many questions are on the exam and how long is it?
ARRT's R.R.A. pages in our source material do not state a question count or time limit, so we don't publish a figure. Confirm the current format through ARRT's Examination Content Specifications and application handbook, or contact ARRT at 651.687.0048 and choose the option for earning an ARRT credential.
What score do I need to pass, and what does the exam cost?
Our source material does not state a passing score or an R.R.A. application or exam fee. Rather than carry forward an outdated number, we leave these blank. Check ARRT's Application Fees page and the R.R.A. eligibility pathway application handbook, or call ARRT, for current figures before you budget or schedule.
If I fail, how soon can I retake the exam?
ARRT's R.R.A. pages in our source material do not describe a retake policy, including any waiting period or attempt limit. Confirm the current rules with ARRT directly or in the application handbook before assuming a timeline. Do not schedule a retake based on secondhand information.
How long is the credential valid, and what keeps it active?
Our source material does not state a validity period for R.R.A. certification and registration. ARRT maintains a separate Ongoing Requirements section covering what registrants must do to maintain their credential, and a Resources for Maintaining Your Credential page. Review those before your renewal cycle rather than relying on general assumptions.
What is the smartest study order?
Start with ARRT's Examination Content Specifications so your study map comes from the source, then work domain by domain. Build Patient Assessment and Management first, since patient safety and assessment decisions frame procedure selection. Move to Clinical Procedures, then Radiologic Imaging and Image Evaluation, where you apply assessment and technique knowledge to image critique.
What are common failure modes on exams like this?
Three recur: memorizing procedures without the assessment rationale behind them, skipping image evaluation because it feels subjective, and studying only from secondary summaries. ARRT publishes content specifications and entry-level clinical activities for a reason. Anchor every topic to those documents, and use your program's didactic and clinical portfolio work as the practical backbone.
How does the RPA to R.R.A. pathway fit in?
ARRT maintains a separate RPA to R.R.A. Pathway page for radiology practitioner assistants interested in pursuing the R.R.A. credential. If you hold an RPA credential, review that pathway before starting the standard eligibility route, since the requirements you need to satisfy may differ from those for radiographers entering fresh.
Is this study guide affiliated with ARRT?
No. This is independent study material prepared for exam preparation and is not affiliated with, endorsed by, or sponsored by ARRT. All credential requirements, content specifications, fees, and policies should be verified against ARRT's official publications, which control in the event of any discrepancy with this page.
