Quit worrying about it. All cheaters get is a grade, or certification or diploma. Worry about teaching people. Worry about people learning. Quit measuring people.

People will cheat, and maybe they are great scam artists and will be able to cheat through the rest of their life. Those few and the others who screw themselves by not learning aren't worth being concerned with. Spend (all) your effort on those who want to learn.

Awarding diplomas to unqualified individuals degrades the value of the diploma. Schools can't afford to risk their reputation; they must assess students in some way.

Diplomas are already degraded and degrading.

Schools are worried about reputation and their profit. My point is they should be worried about teaching.
