From The College Board (SAT) Website

Students whose March SAT exam was cancelled
will receive a refund and can schedule for another exam. The May SAT has also
been cancelled. Make sure you’re registered for the June SAT Exam. More info here.

New message posted on the ACT website
regarding the April ACT Exam

“The safety of students and test center staff is our top priority. We have rescheduled the April 4 national test date across the U.S. in response to concerns about the spread of the corona virus (COVID-19).

All students registered for the April 4 test
date will receive an email in the next few days informing them of the
postponement and instructions for free rescheduling to June 13 or a future
national test date.”

Regarding AP Exams:

The AP Program is developing resources to
help schools support student learning during extended closures, as well as a
solution that would allow students to test at home, depending on the situation
in May. Additional information will be posted by March 20.

We will announce portfolio submission
deadline extensions for AP 2-D Art and Design, 3-D Art and Design, Computer
Science Principles, Drawing, Research, and Seminar courses by March 20. Schools
do not need to call AP Services for Educators to request these extensions.
