Leaked ACT college admissions test canceled hours before students were to take it

The ACT — the most widely used college admissions exam — was canceled for thousands of test takers planning to take it in South Korea and Hong Kong on Saturday after it was found to have been leaked in advance.

ACT Inc., which owns the ACT, took the action after learning on Friday that the test had leaked, though it did not say how or where, according to an ACT statement (which you can read below in full). Some 5,500 students were affected, according to Reuters. The statement says all will get a fee registration refund. But the test will not be rescheduled, and those students who want to take it will have to wait until the next scheduled administration, in September.

Bob Schaeffer, public education director for the nonprofit National Center for Fair and Open Testing, known as FairTest, said that the cancellation notice was sent out at about 6 a.m. on Saturday, Asia time (Hong Kong and South Korea are one hour apart) just a few hours before ACT test centers were scheduled to open.
