The students showed up Saturday at Lovejoy High School in Hampton prepared to take the test, which is needed to apply for many colleges and universities, The Atlanta Journal-Constitution reported.
The school district makes schools available for the testing, but the testing organization administers the exams, Clayton County Public Schools interim Superintendent Luvenia Jackson said.
The company is working to reschedule the test as soon as possible, ACT spokesman Ed Colby told The Associated Press Monday morning.
The test supervisor didn’t show up, and never informed ACT officials that she wouldn’t be there, Colby said. He wasn’t sure why she failed to show.
The ACT will work with students to reschedule the exam as soon as possible, Colby said.
“Obviously that’s our No. 1 priority, is meeting the needs of those students who were expecting to take the test that day,” he said.
