When and Where Can I Take it?

The exams are held over 250 Pearson VUE testing centers located throughout the U.S. and various international sites. You will be given access to a complete list of available times and dates for each location.

Most testing sites are open from 9 am to 5 pm Monday through Friday, with some being open on Saturdays as well. All DTR exams are computer administered.

Once you have scheduled your exam, you will be sent a confirmation email for your records. It is important that you keep this, as you will need to bring it to the testing site for admission.

This must include your full name as it appears on your registration, signature, and a recent and recognizable photo. IDs with missing or incorrect information will not be accepted.
