Yes, walk-ins are still permitted with the new registration process.
However, since test takers have to register and pay through My Account and bring a copy of their registration ticket with them on exam day, they should be encouraged to register prior to their arrival at the test center.
In order to accommodate walk-ins, test takers must have access to a computer with internet access to log in to My Account to register, pay their exam fee, and print their registration ticket. It is recommended that an extra computer be available for test takers to use for this purpose. If your test center does not have an extra computer, please send test takers to the campus library or computer lab.
Also, whether you choose to accept walk-ins at your test center will depend on your test center's seating capacity and hours of operation.
