IOWA CITY, Iowa (AP) — The University of Iowa is apologizing after a temporary employee mistakenly sent an email to 2,000 students that included a document showing all of their grade point averages. The school said Thursday that students served by the Center for Diversity and Enrichment received the e-mail Wednesday that included a data attachment with their names, number of credit hours and grade point averages.

University officials apologized to students, saying they understand the breach “may have caused undue stress.” The university said counseling resources were available and that steps were “being taken to remedy the situation and to ensure that such mistakes do not occur again.” Students have been instructed to delete the attachment, and shred any copies they printed out because personal grade information is protected under federal student privacy law.
