On March 8, the College Board announced and released the 2021 AP Exam Terms and Conditions, along with the testing schedule for this year.
The College Board offered three testing windows, and Fairfax County Public Schools chose Administration 2, which makes the exam dates for FCPS students May 18-28. While Administration 1 offers all exams in-person, Administrations 2 and 3 offer a blend of traditional in-person tests and digital exams that can be completed from home or at school on an authorized, internet-connected device.
