- The R.R.A. is issued by ARRT and requires current ARRT Radiography certification and registration before you can qualify.
- Program completion on or after January 1, 2023 requires a master's or doctoral degree.
- Completion on or after January 1, 2025 adds two years of post-Radiography patient-care imaging experience, not earned concurrently with RA-program activities.
- Standard eligibility must be established within three years of completing the professional program; you get three exam attempts in that window.
Who These Requirements Apply To
The Registered Radiologist Assistant credential, written R.R.A. in ARRT's official styling, is an advanced-practice credential for radiologic technologists who work under the supervision of a radiologist. It is not an entry-level certificate. Before you can even apply, you must already hold a foundation credential, complete a recognized radiologist assistant program, and document supervised clinical work. If you are still sorting out the basics of the credential itself, start with What Is RRA? and What Does RRA Stand For?, then return here for the qualification rules.
This article is organized around a practical question: which rules apply to me, given when I finished my program? The answer changes depending on your completion date, and the details matter because ARRT published different degree and experience rules for different eras. Always confirm the final wording against the current ARRT Education Requirements (revised March 31, 2026) and the 2026 Registered Radiologist Assistant Handbook before you commit to a plan.
The Core Eligibility Pillars
Standard eligibility for the R.R.A. examination rests on a set of requirements that all have to be satisfied together. Think of them as parallel tracks rather than a single checklist you can finish in order.
| Requirement | What It Means in Practice |
|---|---|
| ARRT Radiography credential | Current ARRT Radiography certification and registration, not a lapsed or expired status |
| Recognized RA program | Completion of a radiologist assistant educational program that ARRT recognizes |
| Graduate degree | Master's or doctoral degree for program completion on or after January 1, 2023 |
| Clinical experience | Two years of full-time patient-care-related medical-imaging experience for completion on or after January 1, 2025 |
| Clinical portfolio | Documented clinical requirements submitted through the application packet |
| ACLS | Current Advanced Cardiac Life Support certification |
| Ethics | Compliance with ARRT ethics requirements |
The most common surprise for candidates is the dependency on the Radiography credential. The R.R.A. sits on top of Radiography, so letting that registration lapse can derail an otherwise complete application. Treat Radiography renewal as part of your R.R.A. qualification timeline, not a separate chore.
Degree and Experience Rules by Completion Date
Because ARRT raised its standards in stages, your program completion date determines which degree and experience rules apply to you. Keep these tiers separate in your mind; mixing them is the fastest way to misjudge your eligibility.
Completed on or after January 1, 2023: graduate degree required
If you finished your radiologist assistant program on or after January 1, 2023, a master's or doctoral degree is required. Earlier degree exceptions exist in ARRT's published rules, but they belong to earlier completion eras and are not an alternative route for current completers. If your completion date is recent, plan around the graduate-degree requirement, not the older exceptions.
Completed on or after January 1, 2025: add the experience requirement
For completion on or after January 1, 2025, ARRT requires two years of full-time patient-care-related medical-imaging experience after you earned your Radiography credentials. Two details deserve emphasis:
- It follows Radiography. The clock starts after the Radiography credential, so experience gained before you were credentialed does not count toward this requirement.
- It cannot overlap with the program. The experience cannot be earned concurrently with radiologist assistant program activities. Hours you spend in RA coursework or RA clinical rotations do not double as the two years.
Quick Self-Check by Completion Date
- Before January 1, 2023: earlier rules and exceptions may apply; consult the published ARRT education requirements for your era.
- January 1, 2023 to December 31, 2024: graduate degree required; the shorter pre-2025 experience rule applies.
- On or after January 1, 2025: graduate degree plus two years of non-concurrent, post-Radiography, full-time imaging patient-care experience.
Clinical Portfolio, ACLS, and Ethics
Three requirements are easy to underestimate because they are documentation tasks rather than coursework.
The clinical portfolio
The clinical portfolio requirements were implemented in January 2023 and are documented in the Registered Radiologist Assistant Certification and Registration Application Packet. The portfolio is where you demonstrate the supervised clinical competencies that your program and preceptors verified. Start collecting signatures and records early. Chasing a preceptor for sign-off after graduation is a classic source of avoidable delay, especially when your three-year clock is running.
Current ACLS certification
You need current ACLS certification at the time of application. Because ACLS cards expire on their own schedule, check the expiration date against your planned application and exam window. If your card would lapse between submitting your application and testing, renew proactively rather than risk a documentation problem.
Ethics compliance
ARRT applies its ethics requirements to every applicant. Review the ethics standards and the application's disclosure questions carefully, and if anything in your history might require explanation, address it with ARRT before you invest in a testing date.
Key Takeaway
Build a single tracking sheet with four rows: Radiography registration expiry, ACLS expiry, portfolio sign-offs outstanding, and experience-months accrued. Review it monthly until your application is filed.
The Three-Year Window and Attempt Limits
Ordinary eligibility, including degree completion, must be established within three years of completing the professional program. This is the clock that governs most candidates. If you delay completing a required element, such as finishing the degree or accumulating experience, you can run out of time even though you were once on track.
Inside that window, ARRT allows three examination attempts within three years. That limit shapes how you should treat your first sitting: it is one of a finite set, not a free trial. For a data-driven look at how first-time candidates have fared, see RRA Pass Rate 2026: What the Data Shows. The calendar-2025 first-time pass rate was 75.0%, but it comes from a small cohort of 24 first-time candidates, so read it as a signal rather than a guarantee.
If you do need to retake the exam, the reapplication fee is USD 200. Planning your preparation so that attempt one is a genuine attempt, not a diagnostic, protects both your budget and your attempt count. Our overview in How Hard Is the RRA Exam? explains where candidates tend to struggle.
The RPA-to-R.R.A. Admission Pathway
ARRT also publishes a separate admission route for qualified radiology practitioner assistants. This pathway leads to the same R.R.A. examination, not to a replacement or lesser credential. The requirements differ from the standard route:
- Current CBRPA and ARRT Radiography credentials, plus current clinical practice.
- One of three education-and-experience combinations: a master's or doctorate; or a bachelor's plus two years of imaging experience; or an associate degree plus four years of imaging experience.
- The ordinary three-year post-program deadline is waived for this route.
The pathway is documented on the ARRT RPA-to-R.R.A. credential-options page, and anyone considering it should read that page directly because it governs the details. The key conceptual point is that the pathway changes how you become eligible, not what you are tested on. Once admitted, you sit the same examination as everyone else.
Fees, Dates, and Application Mechanics
What you pay
| Item | Amount |
|---|---|
| Initial application/examination fee | USD 225 |
| Reapplication fee | USD 200 |
| Annual renewal fee | USD 65 |
No member versus nonmember exam fee differential is listed. The ordinary annual renewal fee covers the registrant's ARRT credentials rather than charging separately for each discipline. For the full picture, including costs outside ARRT's fees, see RRA Certification Cost 2026: Complete Pricing Breakdown.
Windows and deadlines
The exam is delivered at Pearson test centers. ARRT announced an additional October 2026 administration. The next published window after October 14, 2026 is January 13-16, 2027, with an application postmark deadline of November 11, 2026. Because applications must be postmarked well ahead of the testing window, work backward from the deadline when planning your documentation. Full scheduling detail lives in RRA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
What You Qualify to Sit: Exam Format and Content
Understanding the exam you are qualifying for makes the requirements feel less abstract. The R.R.A. exam has two sessions with no personal reference materials or personal calculator allowed; an approved supplied or on-screen calculator is available.
- Session 1: 200 scored selected-response questions plus 30 pilot questions, four hours.
- Session 2: two hours, with at least 30 scored case-study questions plus a variable pilot allocation. The 2026 handbook table displays 30+ scored and 20+ pilot items and labels the overall total approximately 280.
- Testing time: six hours of testing; the full appointment is 410 minutes including the break and non-testing activities.
- Case studies: objectively scored, not the essay format used before January 2023.
- Navigation rule: Session 1 cannot be reopened after Session 2 begins.
The passing standard is a scaled score of 75 on a 1-99 scale, not 75% correct. Read RRA Passing Score 2026: Exactly What You Need to Pass to avoid the common misunderstanding.
The eight reported content areas
ARRT's annual exam report publishes whole-exam weights across eight categories. Selected response contributes 75% of points and case study contributes 25%.
| Domain | Weight |
|---|---|
| Patient Management | 14% |
| Pharmacology | 7% |
| Patient Safety, Radiation Protection, and Equipment Operation | 11% |
| Abdominal Section | 16% |
| Thoracic Section | 9% |
| Musculoskeletal and Endocrine Sections | 9% |
| Neurological, Vascular, and Lymphatic Sections | 9% |
| Case Study | 25% |
Two clarifications keep you from misreading the structure. First, the 2023 content specification organizes selected-response objectives under Patient Care (56 scored items), Safety (28), and Procedures (116). Those are item counts within the specification, not whole-exam percentage weights, so do not try to reconcile them with the table above. Second, Procedures is the largest selected-response parent category, Case Study is the largest separately reported weighted category, and Abdominal Section is the largest separately reported procedural category at 16%. A full breakdown is in RRA Exam Domains 2026: Complete Guide to All 8 Content Areas.
Why the weights matter for qualification planning
Candidates often finish their programs strong in the procedural sections they performed most often and weaker in areas their sites rarely covered.
- Pharmacology is the smallest category at 7% but is easy to neglect if your clinical site seldom involves contrast or sedation decisions.
- Case Study carries 25% and rewards integrated reasoning across sections, so treat it as its own skill rather than a leftover.
- Abdominal Section at 16% is the single biggest procedural block; gaps there cost more than anywhere else.
Staying Qualified After You Earn It
Meeting the requirements once is not the end. To keep the credential, you need to maintain it.
- Annual renewal is normally due by the end of your birth month, at USD 65.
- Supporting Radiography credentials must be maintained. Letting Radiography lapse puts the R.R.A. at risk.
- Biennial continuing education totals 50 credits, including at least 25 Category A+ credits and at least 35 RRA-relevant credits. These are overlapping requirements, not additive totals, so a single well-chosen credit can count toward more than one.
- Continuing Qualifications Requirements (CQR): all RRA credentials have a ten-year CQR cycle.
The practical lesson is that the qualification tracking sheet you built for the application should evolve into a maintenance tracker.

A Requirements-First Planning Sequence
Because eligibility and preparation overlap in time, sequence your effort so documentation never becomes the bottleneck. The timeline below ties study focus to specific exam domains rather than generic weekly tasks.
Lock down eligibility
- Confirm your completion-date tier and the degree and experience rules that follow from it.
- Verify Radiography registration, ACLS expiry, and portfolio sign-offs.
File against the postmark deadline
- Submit to meet the November 11, 2026 postmark deadline if targeting January 13-16, 2027.
- Pay the USD 225 initial fee.
Weakest procedural sections first
- Start with Abdominal Section (16%) and Pharmacology (7%) if your clinical exposure was thin there.
Systems and safety
- Thoracic, Musculoskeletal and Endocrine, Neurological/Vascular/Lymphatic, then Patient Safety, Radiation Protection, and Equipment Operation.
Integration
- Case Study practice across all sections, plus full-length timed runs that respect the Session 1 and Session 2 structure.

When you are ready to test yourself under realistic conditions, our RRA practice tests mirror the selected-response and case-study formats you will face.
Frequently Asked Questions
Yes. Standard eligibility requires current ARRT Radiography certification and registration. The Radiography credential must also remain maintained after you earn the R.R.A., since supporting credentials must be kept current.
For radiologist assistant program completion on or after January 1, 2023, a master's or doctoral degree is required. Earlier completion eras had different degree rules, so confirm your completion date against the ARRT Education Requirements.
No. For completion on or after January 1, 2025, the two years of full-time patient-care-related imaging experience must come after your Radiography credentials and cannot be earned concurrently with radiologist assistant program activities.
Ordinary eligibility, including degree completion, must be established within three years of completing the professional program. The RPA-to-R.R.A. admission pathway waives this ordinary three-year deadline.
No. The RPA-to-R.R.A. pathway is an alternate admission route to the same R.R.A. examination. It requires current CBRPA and ARRT Radiography credentials and current clinical practice, plus a qualifying education-and-experience combination.
Qualifying for the R.R.A. is mostly a matter of matching your completion date to the right rules, documenting your clinical work early, and protecting the credentials that support the application. Once those pieces are in place, your focus can shift entirely to mastering the eight content areas and the case-study format.
