The stats suggest a serious rise in cheating, at least compared to what I remember from decades ago. The article could have been improved by listing similar offenses from 10 or 20 years ago for comparison. If in fact cheating is on the rise, or at least reported cases are on the rise, it's hard to understand why "reluctance to report someone" is currently considered a significant issue.
Although a reprimand sounds less serious than probation, it's unclear what the difference would be in terms of a student's uninterrupted participation in coursework. Also, I don't see any discussion of penalties *increasing* for repeat offenders, which is something that needs to be accounted for.
