CDT Taking the Exam

Taking the CDT Exam

CSI offers the CDT examination twice annually in the Spring and the Fall. Open registration for the test begins in the Winter and Summer respectively. This page will update with additional information on the application process during the registration period.

An Authorization To Test (ATT) Notification will be emailed to you within 1-2 weeks of your application being processed. Candidates who register after the early registration deadline will receive an ATT email the week after they register.

The Authorization To Test (ATT) email contains all of the necessary information for scheduling a Prometric appointment, including the exam candidate's National ID number.

What is allowed/required for entry at the test center?

One form of non-expired, government-issued, photo- and signature-bearing ID must be provided when entering the Prometric test center. Acceptable forms of ID are:

• Driver’s License 
• State or government-issued ID 
• Passport 

IMPORTANT: ID must have FIRST and LAST names that identically match those used for registration; middle names and suffixes are not required. The address used for registration does not have to match the address on the ID.

What Prometric test centers are available to exam candidates? Exam candidates can choose from any of the Prometric test center locations in the United States and Canada. CSI's current contract with the test vendor does not permit testing outside of these locations.

How long is the exam? The computer-based CDT examination lasts two hours and contains 120 multiple-choice questions.

Where do I take the exam? The exam is administered at Prometric test centers in the U.S. and Canada. To view the Prometric test center locations, visit www.prometric.com/CSI and select "Schedule."
