ARRT Radiography Pass Rate, Format & Study Guide

The ARRT Radiography content specifications (board approved January 2021, implemented January 1, 2022) divide the 200 scored questions into Patient Care 33, Safety 50, Image Production 51 and Procedures 66; each exam also carries 30 unscored pilot questions. ARRT reports a scaled score from 1 to 99 and a scaled score of 75 is required to pass; the number of correct answers behind 75 varies by exam version and is not a percentage. The primary handbook lists 230 minutes of testing time; the portal mock uses the 200 scored questions in 200 minutes.

Many states use ARRT certification as a basis for licensing radiographers, and employers often ask for it.

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.

ARRT limits the number of attempts within a set period and requires a new application for a retake; confirm the current rule in the ARRT primary handbook.

ARRT requires a scaled score of 75 on a 1 to 99 scale, and the number of correct answers behind that score varies by exam version, so the percent score in the portal mock is only a rough self-check. Format: 200 scored questions plus 30 unscored pilot questions; the portal mock uses 200 questions in 200 minutes and does not include the pilot questions. No official pass rate is available for this exam, so none is quoted here.
