Instructions for scheduling your examination appointment online with Prometric
Go to Prometric. Click on the Schedule, Reschedule/Cancel or Confirm button.
Select the country (and also the state, if applicable) in which you would like to take your examination, and then click on Next.
Click on Schedule.
Note: If you wish to change or cancel a scheduled examination appointment, rather than schedule an appointment, you would instead click on Reschedule/Cancel. You would then be requested to enter your Confirmation Number (obtained at time of scheduling the original examination appointment) rather than your Authorization To Test (ATT) Number.
