The SPEX is administered through a national computer-based testing network called Prometric Testing Centers. The test can be scheduled Monday through Friday throughout the year; some locations have Saturday hours.

There are more than 300 test sites across the United States and Canada. Test site information will be provided to examinees upon contacting Prometric to schedule their exam. Test site information is also available on Prometric's website.

The Scheduling Permit must be received before an applicant can contact Prometric to schedule a testing appointment. Appointments are assigned on a "first-come, first-served" basis; therefore, applicants should contact Prometric to schedule as soon as possible after receiving the Scheduling Permit. Applicants may take the test on any day that it is offered during the assigned eligibility period, provided that there is space at the chosen Prometric Test Center.
