When we approve your application, we will send you an email notifications with instructions on how to log into your Online Profile and print your Authorization to Test (ATT) letter. Test centers fill up quickly (particularly at the end of each exam
testing period) so apply and schedule your exam early. If you wait until
the exam period starts, you might not even be able to schedule an exam
appointment at all. This happens rarely, but if it happens to you, you
may withdraw from the exam and apply for a 50 percent refund of your
exam fee.
