How RTBS Scheduling Actually Works
Candidates searching for "RTBS exam dates" often expect a printed calendar of a few national test days. That is not how this exam works. The Registered Technologist - Breast Sonography credential is earned through the American Registry of Radiologic Technologists (ARRT), and the exam is delivered by computer at Pearson VUE testing centers. Your "date" is therefore something you build: you establish eligibility, apply, receive authorization, and then book an appointment at a center.
That means the dates that matter most are personal ones: when your clinical experience window opens and closes, when your structured education was completed, when your application is approved, and how long you have to test once authorized. The exam itself is rarely the bottleneck. The documentation behind it usually is.
This guide walks through each of those date-driven checkpoints, with a focus on the 2026 changes. For the full list of prerequisites, see our breakdown of RTBS requirements, eligibility, and how to qualify.
Confirming You Mean ARRT Breast Sonography
Before you plan anything, make sure you are planning for the right credential. On this site, RTBS refers to the ARRT postprimary Breast Sonography (BS) credential. It is distinct from two similar-sounding options:
| Credential | Issuing body | Relationship to RTBS |
|---|---|---|
| Breast Sonography (BS) | ARRT | This is the credential covered here |
| Breast (BR) | ARDMS | Different registry, different application and exam; not interchangeable |
| Sonography (S) | ARRT | A general sonography primary pathway; can serve as a supporting category for BS |
If your employer asks for "breast ultrasound certification," clarify which registry they mean. The date planning below applies only to the ARRT route. For background on the name itself, see what RTBS certification is.
The September 1, 2026 Blueprint Change
The most important date in this entire topic is September 1, 2026. That is the effective date for the Breast Sonography Examination Content Specifications (board approved July 2025), and also for the updated structured education and clinical experience requirements. Alongside the revised blueprint, a new Standard Setting Report takes effect in September 2026.
Why this matters for scheduling:
- Content shifts. The scored-question allocations in the current specification are Patient Care 16, Image Production 105, and Procedures 64. Older study materials that cite an 18/102/65 split are outdated.
- The passing standard was revised. The 2025 first-time pass rate of 78.1% among 146 candidates reflects the prior blueprint and passing standard, so it is a loose reference rather than a prediction. Our RTBS pass rate analysis covers how to read that number carefully.
- Requirement documents carry effective dates. The structured education and clinical experience requirements are both effective September 1, 2026. If your clinical logging straddles that date, read the current documents closely.
From Eligibility to Test Day: The Real Timeline
Because there is no fixed national exam day, think of your RTBS timeline as a sequence of gates. Each one has to be cleared before the next opens.
Gate 1: Supporting-category credential
You must hold a current supporting-category credential. The qualifying combinations are:
- Radiography plus Mammography, or
- Sonography, or
- Vascular Sonography
The Sonography and Vascular Sonography supporting credentials may be held through either ARRT or ARDMS. The Vascular Sonography route is explicitly listed in the 2026 handbook's supporting-category table, so do not assume it is excluded. If your credential is lapsing, renew it first; a gap here can stall everything downstream.
Gate 2: Ethics compliance
ARRT ethics compliance is required. If you have anything to disclose, resolve it early, because review can take time and sits outside your control.
Gate 3: Structured education
You need 16 structured-education hours completed within the 24 months before you apply, with at least one credit in each major category. Credits that age out of the 24-month window do not count, so avoid completing education long before your clinical hours are finished.
Gate 4: Clinical experience
The clinical component is covered in detail in the next section, because it is the gate that most often dictates when candidates can actually apply.
Gate 5: Application and fee
Once the above are documented, you submit the application and pay the fee. After approval, you schedule with Pearson VUE. Our RTBS certification cost breakdown lays out every dollar figure you may encounter along the way.
Protecting Your 24-Month Clinical Window
Clinical experience is where scheduling goes wrong. The rules are specific, and they all hinge on the same 24-month qualifying window.
Clinical Experience Requirements (effective September 1, 2026)
Within the qualifying 24-month window, you must document:
- 200 independently performed, nonsimulated breast examinations
- Participation in at least 20 approved elective procedures
- Bilateral examinations count as two examinations
- No more than nine procedures may be logged per day
- Scanning must be physically onsite
- Each mandatory examination must be presented to the radiologist for final interpretation
The nine-per-day cap is the detail that quietly lengthens timelines. Even in a high-volume department, you cannot compress 200 exams into a handful of heavy days. Combined with bilateral counting as two, the cap shapes how quickly a motivated candidate can finish. Work backward from your target test month and confirm that your realistic caseload fits inside the window.
Because the window is rolling, your earliest logged exams can age out if you stretch the process. Candidates who log slowly, then pause for months, sometimes find that early cases no longer qualify. Review your log monthly and track the date your oldest qualifying case expires.
Key Takeaway
Build a one-line tracker for your clinical window: the date your oldest qualifying exam falls out of the 24-month range, your running exam count, and your elective-procedure count. If the expiry date is approaching and your count is short, you have a scheduling problem to solve now, not at application time.
Fees and Attempts That Affect Your Dates
Money and attempt limits both influence when you should book. These are the figures from ARRT's current fee and attempt rules:
| Item | Detail |
|---|---|
| Application/exam fee | $225 USD |
| Fee using an ARDMS supporting credential | $450 USD |
| Reapplication | $200 |
| Attempts allowed | Three within three years before requalification |
| Annual registration renewal | $65, regardless of how many ARRT credentials you hold |
The attempt rule deserves emphasis: it is three attempts within three years, not three per year. Spending an attempt before you are ready does not just cost a reapplication fee; it consumes a finite resource. A rushed first sitting aimed at hitting a self-imposed deadline is usually a poor trade.
If you are weighing the investment itself, read whether RTBS certification is worth it alongside the RTBS salary guide before committing.
What to Expect When the Appointment Starts
Once you book, your appointment is longer than your exam. The format details below come from the ARRT postprimary handbook.
Exam Format at a Glance
- Delivery: Pearson VUE computer-based testing center
- Total questions: 225, made up of 185 scored items and 40 unscored pilot items
- Testing time: 225 minutes
- Appointment length: 245 minutes (the extra time covers check-in and administrative steps)
- Open or closed book: Closed book
- Calculator: No personal calculator; a test-center-supplied calculator or an on-screen calculator is available
The exam is primarily one-best-answer multiple choice, but the handbook also permits other formats, including multiple-response, sorting, and image or video items. You cannot tell which questions are the unscored pilots, so treat every item as if it counts.
Do not confuse the 225 testing minutes with the 245-minute appointment. Plan your day around the longer figure: arrive early, expect check-in procedures, and budget energy for the full block. You will also see claims elsewhere that this exam runs three hours; that does not match the handbook's exam-length table.
For a sense of how demanding this format feels in practice, see how hard the RTBS exam is.
A Domain-Based Prep Calendar
Rather than a generic study plan, anchor your calendar to the blueprint. The scored-question allocations tell you where your hours should go, and Image Production dominates.
| Domain | Scored questions | Subcategory notes |
|---|---|---|
| Patient Care | 16 | Smallest allocation; steady review rather than heavy blocks |
| Image Production | 105 | Basic Principles of Ultrasound 32; Image Formation 37; Evaluation and Selection of Representative Images 36 |
| Procedures | 64 | Second-largest; breast imaging and interventional-adjacent knowledge |
Use these counts as your guide to proportion. Our complete guide to the three RTBS content areas goes deeper on each domain.
Image Production: Physics and Formation
- Basic Principles of Ultrasound (32 questions): wave behavior, transducer physics, and artifacts
- Image Formation (37 questions): instrumentation, optimization, and how settings change the image
- Finish this early because it supports everything else
Image Production: Representative Images
- Evaluation and Selection of Representative Images (36 questions)
- Practice with image and video items, since these formats appear on the exam
Procedures
- Cover the 64 scored questions with attention to what each procedure requires from the sonographer
- Tie concepts to the exams you logged clinically
Patient Care and Full Review
- Patient Care (16 questions): communication, safety, and professional practice
- Take timed practice sets and revisit weak subcategories
This sequence puts the heaviest, most foundational material first and reserves the smallest domain for the final stretch, when you can combine it with timed practice. For a fuller methodology, see the RTBS study guide, and keep the RTBS cheat sheet handy for last-week review. When you are ready to simulate the real thing, our RTBS practice tests mirror the multi-format question style.
After You Test: Scores and Renewal Dates
Your dates do not end at the test center. Two later timelines matter once you pass.
Scoring
The passing score is 75 on the 1-99 scaled-score system. That is not 75% correct. Scaled scoring means the raw number of correct answers needed can differ by exam form. The Standard Setting Report gives a form-specific raw-score equivalent and a projected pass rate, not a universal raw cutoff and not an observed 2026 result. Read exactly what you need to pass for the full explanation.
Maintaining the credential
- Annual registration renewal: $65 per year, regardless of how many ARRT credentials you hold.
- Continuing education: ordinarily 24 approved CE credits per two-year biennium.
- Continuing Qualifications Requirements (CQR): credentials earned on or after January 1, 2011 require CQR every ten years.
Mark your first renewal and your biennium end date the day you pass. Missing a renewal can jeopardize an active credential, which also matters if it is the supporting credential underlying your breast sonography eligibility. Once credentialed, explore RTBS jobs to see where the credential is put to work.
Frequently Asked Questions
No. The exam is delivered by computer at Pearson VUE testing centers, so you schedule an appointment after your application is approved rather than choosing from a few national test days. Availability depends on your chosen center, so check current openings through ARRT's scheduling instructions.
The appointment is 245 minutes, which includes check-in and administrative time. The actual testing time is 225 minutes for 225 questions, of which 185 are scored and 40 are unscored pilot items.
The Breast Sonography Examination Content Specifications, along with the structured education and clinical experience requirements, are effective September 1, 2026. A new Standard Setting Report also takes effect in September 2026, so confirm that your study materials match the current blueprint.
You are permitted three examination attempts within three years before requalification is required. It is not three attempts per year, which is why scheduling your first attempt only when you are well prepared is worthwhile. Reapplication after an unsuccessful attempt costs $200.
It can. The 200 nonsimulated breast examinations and 20 elective procedures must fall within the qualifying 24-month window, as must your 16 structured-education hours. If you pause for a long period, your earliest qualifying work can age out, so track the expiration date of your oldest logged case.
Your RTBS date is ultimately set by how well you manage your own documentation, not by a published calendar. Confirm your supporting credential, protect your 24-month window, align your prep with the September 1, 2026 blueprint, and book only when your practice results show you are ready.
