"Our primary concern at this time is the health and safety of students and our testing staff," said Ed Colby, a spokesman for ACT. “As CDC and local guidelines for safety allow, in addition to our planned June 13 and July 18 test dates, we will be offering new test dates on June 20 and July 25 to provide students with options to schedule and reschedule their registration," he said. "We will also offer a remote proctoring option for the ACT test, allowing students to take the test at their home on a computer. As early as August, we will begin offering students a practice experience with the at-home ACT and will launch the option in late fall/early winter 2020 as part of our national testing program. We'll be releasing more information soon."
