Test sheets of 182 students who took the ACT college-readiness exam last month at Upper Darby High School in Pennsylvania are missing.
ACT Inc. believes the tests were sent back on Sept. 15. The ACT-hired testing coordinator was supposed to use FedEx, but sent them through the U.S. mail.
Students can retake the test or get their money back. The testing service also will provide students with a letter, explaining the problem, to include with their college applications, an ACT spokesman said.
