Standby test taking is not permitted. In some cases, you can request Waitlist Status if you miss the last registration deadline, or if your paper registration has been returned unprocessed without enough time to resubmit it.
Waitlist Status may be available beginning from the last registration deadline up until five days before test day. Although every effort will be made to seat applicants who request Waitlist Status, we cannot guarantee that you will be admitted to the test center on test day. Those on the Waitlist are seated after all regularly registered test-takers have been admitted and if sufficient test materials, staff and seating are available.
