About American Registry of Radiologic Technologists (ARRT)

Understanding the structure of the exam and beyond is critical to success.

With high-quality patient care at the core of its mission, the American Registry of Radiologic Technologists (ARRT) focuses on education and ethics to ensure only the most qualified medical imaging professionals receive ARRT credentials. The Computed Tomography examination is one of the most comprehensive tests administered by the ARRT.

When creating the CT exam, ARRT uses the most up-to-date information available to create questions that reflect today’s best medical imaging practices. However, it’s not just a matter of covering subject material that today’s technologists will use. ARRT completes periodic practice analysis surveys to ensure each CT technologist is tested on the knowledge, skills, and job responsibilities required to succeed in the profession.

To become an ARRT approved CT technologist, exam review is no easy feat. The Tuffest Stuff curriculum includes mock CT exams that mirror the difficulty of the ARRT exam and cover the content categories and subcategories included on the test.

About CT Registry Exam Day

Before you’re eligible to take the ARRT CT Exam, you must meet a set of requirements:

Achieve ARRT credentials in radiography, nuclear medicine, or radiation therapy.
Present proof of 16 hours of structured education (The Tuffest Stuff CT Registry Review Seminar Solution (online, on-demand) is approved for 16 category A CE credits by the AHRA.
Each also satisfies the ARRT educational requirement to sit for the CT Registry Examination.)
Validate clinical experience via documentation submission of 125 procedures.

Once these steps are completed, you can schedule your CT certification exam. There are more than 200 testing locations in the U.S. and globally.

What If You Fail the ARRT CT Registry Exam?

To pass the CT Registry Exam, you need to earn a score of 75. The scoring is scaled, so 75 is not the percentage. ARRT explains its scoring protocol by saying, “the number of correct answers necessary to obtain a scaled score of 75 will always vary.”

You are allowed three attempts or three years to pass the CT Registry Exam. Once you take the test three times or the three year time period passes, you’re required to requalify for the exam through one of the ARRT approved methods.

While 94% of students pass the ARRT CT Registry Exam on the first attempt after completing The Tuffest Stuff Seminar Solution, failing does not mean certification is out of reach. Learn about how you can pass on your next try with our Bounce Back Program.
