If you’re reading this within a few hours of getting that “Did Not Pass” screen at the testing center, take a breath. You’re not alone, and you’re not finished. The ARRT Radiography retake pass rate is around 65%. With a structured 30-day comeback plan starting after your mandatory 90-day wait, that number gets significantly higher.
This is the plan.
The first week (after the exam)
Don’t open a textbook. The single biggest mistake retake candidates make is panic-cramming the next morning. You need to do three things first.
-
Get your score breakdown. When the official ARRT result arrives (7–14 business days after the exam), it includes a category-by-category breakdown showing which content areas you scored above 50% in and which you scored below. This is the most valuable diagnostic tool you’ll have. Do not start studying without it.
-
Process the disappointment. Honest answer: failing a board exam is hard. You studied for months. You showed up. It’s okay to be upset for a couple of days. Letting yourself feel it is the fastest way to move past it.
-
Tell one person. Not everyone, just one. Your spouse, your closest friend, your study partner. Saying it out loud robs it of the secret-shame energy that makes people stop studying altogether.
The 90-day waiting period: your hidden advantage
The ARRT mandates a 90-day wait between attempts. This is annoying but it’s also a gift. You now have three months instead of three weeks.
Days 1–7: Diagnose. When the score report arrives, sit with it for a day. Make a list of your weakest categories, anything below 50%, and your near-miss categories, anything from 50–65%. The strong categories (above 70%) are not where you’ll spend time.
Days 8–30: Foundational re-learn. Work through the 27-chapter curriculum but spend disproportionate time in your weakest categories. If you scored 35% in Image Acquisition, you need to spend twice as long there as anywhere else. Do not study what you already know just because it feels productive.
Days 31–60: The drill phase. 100 questions a day, but unlike first-time prep, concentrate the mix in your weak areas. If Patient Care is strong, drill 20% Patient Care. If Equipment QA is weak, drill 30% Equipment QA. Use a question bank that lets you filter by category, if it doesn’t, get one that does.
Days 61–80: Mock exams. Take a timed 200-question mock at day 61. Score it. Take another at day 70. Take a third at day 80. By the third mock, you should be hitting 75% or higher overall. If you’re not, slow down and re-drill the still-weak categories.
Days 81–90: The taper and the test. Light review only. Reinforce the high-yield facts (dose limits, four conditions of consent, the 15% rule, photon interactions, workhorse skull projections). Sleep eight hours a night. Schedule the retake for day 91 or later, give yourself a small buffer.
Why retake candidates who follow a plan do better
Three reasons.
Reason 1: You know the testing experience now. First-time test takers are dealing with the testing center logistics, the time pressure, the mental fatigue of 3.5 hours, and the content all at once. You’ve done all that. The cognitive load on the second attempt is lower because you’re only managing the content.
Reason 2: You have your weaknesses in writing. First-time candidates are guessing what their weak areas are. You have an ARRT-issued breakdown saying exactly where you fell short. That data is golden. Use it.
Reason 3: You’re studying with intent. Most first-time candidates spread their study time evenly. Retake candidates who follow a plan focus 60% of their time on the 30% of categories where they actually scored low. That’s how scores move quickly.
Three retake mistakes to avoid
1. “I’ll just retake the same prep tool.” If your prep tool didn’t get you across the line the first time, it almost certainly won’t the second. Switch tools. Use at least two formats, an app for daily drilling, a book for deeper reading, or vice versa. Different formats expose different weaknesses.
2. “I need to study 6 hours a day to make up for failing.” No, you don’t. Two hours a day for 60 days will outperform six hours a day for 20 days. Burn-out is real, and a tired brain doesn’t consolidate memories.
3. “I’ll skip mock exams this time because I already know the format.” This is the most common second-attempt failure. The 3.5-hour, 200-question, single-sitting endurance challenge is its own skill. Practice it. Three timed mocks before retake day is the floor, not the ceiling.
What the score breakdown actually tells you
The ARRT score report gives you a percentage for each of the 8 scoring categories. Here’s how to read it.
| Score in category | What it means | Time allocation |
|---|---|---|
| Above 70% | Strong | Light review only |
| 60–70% | Solid but improvable | Medium drilling |
| 50–60% | Borderline | Heavy drilling, re-read chapters |
| Below 50% | Weak | Full chapter re-learn + heavy drilling |
If you have multiple categories below 50%, prioritize the one with the highest weight on the actual exam. Patient Care (23%) and Image Acquisition (22%) move your overall score the most. Head, Spine, and Pelvis (7%) moves it the least. Same effort, different return.
Special note for candidates with anxiety
If test anxiety contributed to your first attempt result, address it before retake day. Some options that have worked for our beta cohort:
- Practice testing in the same conditions as test day. Set a 3.5-hour timer, no phone, no breaks beyond what the testing center allows.
- Talk to your school’s wellness counselor or your physician. Beta blockers (under medical supervision) are sometimes prescribed for performance anxiety.
- Run through a mental script for the first 20 questions. Many candidates’ anxiety spikes early. If you have a routine (“read carefully, eliminate two, pick the best”), the early questions feel less like ambush.
Retake-day checklist
- ID matching the name on your ARRT registration
- Arrive 30 minutes early
- Sleep 8 hours the night before, not 5, not 10
- Eat a normal breakfast, not a celebration breakfast, not a skipped breakfast
- Bring earplugs (testing centers can be loud)
- Pace at 1 minute per question for the first hour, give yourself 90 seconds for the harder back half
- If you don’t know an answer, eliminate two and pick the best of the remaining two, never leave blank
After the retake
Pass and you’re a registered technologist. Two attempts is normal, the ARRT does not stamp anything on your credentials, and no employer asks how many tries it took.
Don’t pass on the second attempt either? You have one more attempt within three years of your first. Most candidates who don’t pass on the second do pass on the third. The same plan works, diagnose, re-learn the weak categories, drill, mock, taper, retake.
You’re going to pass. Make the plan. Start it.
Get the comeback toolkit
The free tier of Radtechprepper gives you the full first chapter, 50 practice questions, and 1 sample timed exam, enough to test whether the format works for your study style. The Premium subscription unlocks the 751-question bank with category-targeted drilling (filter by weak area), 3 timed full-length mocks, and 14 formulas.
Whatever tool you use: make a plan, stick to it, and trust the 90 days. The retake is not a referendum on your career. It’s a 200-question test. You’ve prepared for harder things.
