- The X-ray (XR) exam has no fixed annual dates - you schedule it yourself within a one-year window.
- Applications go through MyCert and take 2-4 weeks to process before you get a Letter of Approval.
- Once approved, you must schedule and complete testing within one year, with 48-hour cancellation notice.
- The practical exam form is due within six months of your CBT date, or certification stalls.
How IRRSP Scheduling Actually Works
Unlike certifications tied to a handful of annual testing dates, the Industrial Radiography Radiation Safety Personnel - X-Ray (IRRSP) credential from ASNT Certification Services LLC uses a rolling, candidate-driven scheduling model. There is no "spring window" or "fall window" published on a calendar. Instead, once your eligibility is approved, you control when you sit for the computer-based test (CBT) - within limits set by ASNT's deadlines.
This makes "IRRSP exam dates 2026" less about a fixed schedule and more about understanding the sequence of deadlines that govern when you must apply, when you must test, and when your paperwork must be finalized. Missing any one of these checkpoints can push your certification timeline back by months. If you haven't yet reviewed the underlying eligibility rules, start with IRRSP Requirements 2026: Eligibility, Prerequisites & How to Qualify before mapping out dates.
2026 Testing Windows: No Fixed Dates
Because the XR written exam is delivered on demand through Pearson VUE test centers, along with ASNT Authorized Exam Centers at ASNT Houston in Houston, Texas and Applied Technical Services in Marietta, Georgia, there is no published 2026 testing calendar to memorize. Availability depends on seat openings at your chosen center, not on ASNT-set quarterly dates.
What this means practically for 2026 planning:
- You choose your own test date once your Letter of Approval is issued - plan around your work rotation, not around a fixed exam season.
- Popular Pearson VUE locations near major NDT employment hubs can fill up, so booking a few weeks ahead of your target date is wise.
- Because the exam is 100 multiple-choice items in a 3-hour session, there's no need to coordinate around multi-day testing events - a single scheduled block covers the entire written exam.
Key Takeaway
Treat "exam date" as a personal deadline you set based on your Letter of Approval expiration, not a date ASNT assigns to you.
Application Timeline and the Letter of Approval
Everything starts in MyCert, ASNT's application portal. You'll submit a color headshot, a signed Code of Ethics, and documentation proving your eligibility hours. For the XR exam, that means verification of 120 hours or 18 days of documented radiography experience, plus 40 hours or 6 days of radiation safety training, with a workday counted as at least seven hours. An RSO or company personnel officer must verify this documentation - if you need a refresher on exactly what counts, see IRRSP Requirements 2026: Eligibility, Prerequisites & How to Qualify.
After submission, expect a processing time of 2 to 4 weeks before ASNT issues your Letter of Approval. This letter is the trigger for your entire 2026 exam calendar:
- Day 0: Letter of Approval issued.
- Within 12 months: You must schedule and complete your CBT exam.
- Within 6 months of your CBT date: The employer-conducted practical exam form, administered by a current RSO or designee, plus the visual acuity exam, must be completed and submitted.
Certification is not conferred until every one of these pieces - written exam, practical exam, and visual acuity exam - is on file. Plan your 2026 timeline backward from the one-year expiration of your Letter of Approval, not forward from the day you feel "ready."
Fees, Retakes, and What They Mean for Your Schedule
Scheduling decisions are inseparable from cost. The XR exam is priced at $300 for ASNT members and $325 for nonmembers. If you don't pass on the first attempt, retakes are less expensive at $260 (member) or $285 (nonmember). Recertification by examination is priced identically to the initial exam at $300/$325.
These figures matter for date-planning in two ways:
- Because retakes cost less than a fresh application, candidates sometimes schedule a first attempt earlier than they feel fully ready, knowing a retake is financially manageable if needed - though this is not a strategy ASNT encourages and should be weighed against how the exam is scored.
- Cancellations must be made at least 48 hours in advance. Miss that window and you risk forfeiting your scheduling slot and fee, which can push your next available date weeks out.
For a full breakdown of every fee scenario - including recertification pricing - see IRRSP Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Book your test date only after confirming you can cancel or reschedule with at least 48 hours' notice - same-week rebooking is not guaranteed.
Where You Can Sit the XR Exam
Your choice of test center affects how far in advance you need to schedule. Options include:
| Testing Option | Location Type | Scheduling Note |
|---|---|---|
| Pearson VUE centers | Nationwide network | Widest availability; book based on local seat openings |
| ASNT Houston | ASNT Authorized Exam Center, Houston, TX | Fixed location tied to ASNT's certifying home base |
| Applied Technical Services | ASNT Authorized Exam Center, Marietta, GA | Regional option for candidates in the Southeast |
Because Pearson VUE offers the broadest geographic coverage, most 2026 candidates will schedule there. But if you're near Houston or Marietta, the ASNT Authorized Exam Centers can offer a more direct line to ASNT-administered testing.
Deadlines That Can Derail Your Certification
Several deadlines outside the exam date itself are just as critical to your 2026 planning:
The One-Year Letter of Approval Window
Your Letter of Approval is only valid for one year. If you don't schedule and complete the CBT within that window, you'll need to reapply - restarting the 2-4 week processing clock.
The Six-Month Practical Exam Window
Passing the written exam is not the finish line. The employer-conducted practical exam, run by your RSO or designee, plus the visual acuity exam, must be documented and submitted within six months of your CBT date. Certification is withheld until this is complete - a detail many candidates overlook when celebrating a passing score.
The Three-Failed-Attempts Rule
Candidates who fail more than three attempts within a one-year period must complete 20 additional hours of radiation safety training, as determined by their RSO, and wait six months before reapplying. This makes it worth understanding exactly why candidates fail before attempt number one - see How Hard Is the IRRSP Exam? Complete Difficulty Guide 2026 and IRRSP Pass Rate 2026: What the Data Shows for context.
Recertification Deadlines
Certification is valid five years and renewed by examination only. ASNT accepts recertification applications up to six months before your credential expires, but requires them at least 60 days before expiration. Waiting too long into your fifth year can leave insufficient time for processing and scheduling.
Mapping a Study Calendar to Your Exam Date
Once you have a target test date, work backward using the seven topical areas the XR exam draws from: Fundamentals of Radiation Safety, Exposure and Effects, Controlling Exposure, Radiation Detection, Radiographic Equipment, Regulations, and Operating/Emergency Procedures. ASNT does not publish percentage weights per section, but Regulations is by far the deepest area of the body of knowledge - covering definitions, licensing and registration, notices, reports and records, labeling, boundaries and posting, maximum allowable doses, personnel training, transportation, surveys and monitoring, and exposure equipment and storage requirements. Allocate your calendar accordingly.
Fundamentals, Exposure and Effects, Controlling Exposure
- Build baseline understanding of dose limits and biological effects
- Review exposure-control principles (time, distance, shielding)
Radiation Detection and Radiographic Equipment
- Study survey instrument types and calibration basics
- Learn X-ray generator components and exposure device operation
Regulations (heaviest section)
- Work through 10 CFR Part 34 and Suggested State Regulations parts A, E, H, and T
- Drill posting, labeling, and licensing scenarios repeatedly
Operating/Emergency Procedures + Full Review
- Practice emergency-response scenarios
- Take full-length practice exams under a 3-hour, 100-item time limit
This isn't a generic study template - it's shaped specifically by the fact that Regulations carries the most ground to cover among the seven domains.
