FBI agents are among the federal officials examining student transcript changes at St. Cloud State University.
Faculty members have also been interviewed by U.S. Department of Education officials, MPR reported. "They were investigating the effect of transcript alterations, the removal of grades and the possible impact on financial aid eligibility," chemistry professor Jack McKenna, who met with agents on Tuesday, said, MPR reported.
Professors have complained to administration officials that grades they gave students were later removed from transcripts without their knowledge, MPR reported.
News of vanishing grades surfaced a month ago.
The issue may stem from financial aid rules, according to media reports.
One Minnesota Office of Higher Education official told the Associated Press that students who receive financial aid need to maintain a 2.0 grade-point average or higher to continue getting aid. Removing failing grades from a transcript would increase a student's GPA enough to maintain a student's financial aid, she told the AP.
A social work professor told the AP that agents are concerned about fraud, and they were asking her about a student whose grade had been changed.
