Hermione Granger: "And what may I ask do you plan to do if this comes up in the final exam?"
Ron Weasley: "Copy off you?"
Hermione Granger: "No, you won't. Besides, according to Professor McGonagall, we're to be given special quills bewitched with an Anti-Cheating Spell."
Ron Weasley: "That's insulting! It's as if they don't trust us!"
— Discussing final exams[src]

The Anti-Cheating Spell[2] (incantation unknown) was a charm[1] that prevented a person from cheating on a test or exam.


These spells were used at Hogwarts School of Witchcraft and Wizardry on writing quills and parchment to prevent students from cheating during their final exams, as well as their O.W.L.s and N.E.W.T.s. They could be circumvented with Cribbing Spells.
