As of Sept. 4, 2020 ---
You can still register for upcoming SAT dates for the Fall 2020 Semester.
Attached are the listed dates and when you must register for them by (second column).
Test Center Availability and Capacity:
This year, many schools and test centers will have reduced capacity because of social distancing guidelines, and they may encounter unexpected closures. Because of public health restrictions and high demand, there is limited seating capacity for students testing in certain areas. While CollegeBoard cannot directly control capacity and test center availability, we are working to ensure that as many students as possible are able to test safely. If you can't find a test center when you first try to register, try again by logging back into My SAT, selecting the registration you started, and then follow the required steps. On the Select Your Test Center page, you'll see any new seats added in your area. If you can't find a nearby test center with availability on your preferred test date, be sure to check other dates.
