Understanding the ARRT CT Exam Format
The ARRT CT certification exam is a comprehensive assessment administered through Pearson VUE that evaluates your knowledge and skills in computed tomography. Understanding the exam structure is crucial for effective preparation and selecting the right practice questions.
The exam contains 195 total questions, but only 165 count toward your score. The remaining 30 are pilot questions used by ARRT to test new content for future exams. Since you won't know which questions are scored versus pilot, you must treat every question with equal importance.
Practice questions that mirror the actual exam format and difficulty level are essential for success. Generic radiology questions won't adequately prepare you for the specific CT content and application-level thinking required on the ARRT CT exam.
When selecting practice materials, ensure they align with the current ARRT CT content specifications and reflect the exam's emphasis on clinical scenarios and practical application. Our comprehensive practice tests are designed to match the exact format and difficulty level you'll encounter on exam day.
