In the General Info section of the AP Configuration, there is a question "Allow students to signup for the waitlist after registration closes". If you select "Yes" to this question, the registration will not "close" after your registration End Date. You will set a date to close the wait list.
For AP
Students will be able to continue to "register". However, all registrations after the End Date will be automatically added to the Wait List and held for coordinator approval. At the time of approval, the registration will be recorded. At this time students will need to be notified that they need to pay their exam fees. Schools with payment processing can have students log in at www.Student.TotalRegistration.net to pay their outstanding balance.
In the General Info section of the PSAT/NMSQT configuration, you can elect to start a waitlist when the maximum number of registrations is met, or when the registration ends. You will set a date to close the waitlist.
For PSAT
You can also use the Manage Wait-Listed Students report in the Students > Manage Student Requests section of the Report Center. The registration and fees will all be recorded when the waitlist request is approved.
You can ignore waitlist requests that you are not able to approve. These will just stay pending and will not cause any problems in the system.
