Officials at Montana Tech say an investigation has revealed a former employee made more than 100 unauthorized changes to grades given to 36 former or current students, who now face potential disciplinary action.

Chancellor Don Blackketter says that results of the investigation will be turned over to authorities for possible criminal prosecution.

Blackketter declined to name the former employee.

He says eight of the students have graduated and face a possible revocation of their degrees.

Of the remaining 28, he says those who want to return face potential disciplinary action, including expulsion. He says all transcripts have been corrected.

The school has about 2,850 students and is known for its excellence in engineering and science.
