Montana college expels students 4 years after Saudis cheated

BUTTE, Mont. – Fifteen summer school students have been expelled for cheating at Montana Tech, the same college that dismissed several Saudi students and revoked the degrees of others after discovering a former employee altered their transcripts four years ago.

Doug Abbott, vice chancellor for academic affairs, declined to release any other information about the 15 students, including how they cheated, if it was a coordinated effort or if they were international students.

“Montana Tech has high academic standards, and we take academic dishonesty very seriously,” he told The Montana Standard newspaper Wednesday. “I think the permanent dismissal of these 15 students is evidence of the quality education that we give at Montana Tech.”
