DES MOINES, Iowa (AP) — Nearly 200 students who took the ACT college entrance exam at Johnston High School in December have been informed they won’t receive their results. The ACT organization sent an email Monday night to 195 students notifying them their answer sheets never arrived at headquarters in Iowa City for scoring. As a result, ACT says score reports cannot be issued for the Dec. 13 national testing date.

ACT spokeswoman Katie Wacker says as many as 6,000 testing centers administer the exam on national test days, making it difficult to immediately identify if one center’s score sheets don’t arrive. She says instances where test packets don’t show up are extremely rare.

Molly Vincent, whose 17-year-old daughter’s answer sheet was among those lost, says ACT’s notification interferes with her daughter’s scholarship application deadlines.
