ARRT MRI Pass Rate, Format & Study Guide
A real reference for anyone preparing for the ARRT Magnetic Resonance Imaging (MRI) Post-Primary Certification exam — pass rate, retake policy, how it's scored, and a practical study timeline. This is independent reference content, not a sales page: everything below is sourced from ARRT MRI's own certifying body.
Pass rate
The certifying body does not publicly publish an official pass rate for this exam. Be wary of third-party sites citing a specific number here — treat any pass-rate claim you see elsewhere for this exam as unverified.
If you don't pass — retake policy
ARRT allows up to three exam attempts within a three-year eligibility window that begins on the date of your first exam appointment; after any failed attempt you must log into your ARRT account, click Reapply, and pay the listed reapplication fee before a new appointment can be scheduled (at least 24 hours between receiving your new eligibility notice and testing again). Exhaust all three attempts (or the three years) without passing, and you lose eligibility entirely and must requalify by repeating the structured education and clinical experience requirements from scratch.
How it's scored
ARRT reports MRI results on a scaled 1–99 score, with 75 required to pass — a fixed points-based cut score rather than a raw percentage-correct threshold, so scaled scoring adjusts for minor difficulty differences between exam forms. ARRT also reports scaled sub-scores (0.1–9.9) for each content domain on your score report, though only the total score of 75 determines pass/fail.

How to actually prepare
MRI's 200 scored questions (plus roughly 30 unscored pilot items you can't distinguish) lean heavily toward Image Production, which alone makes up roughly half the exam per ARRT's own board-approved content specifications — more than every other domain combined — with Procedures a distant second. Spend the bulk of your 230-minute-appointment prep on pulse sequences, k-space, artifacts, and coil/parameter selection under Image Production before circling back to Safety and Patient Care, which together cover a much smaller share of scored items.
