"They had been given special, new quills for the exams, which had been bewitched with an Anti-Cheating spell."
First years being given these quills for their exams[src]

The Anti-Cheating Spell[2] (incantation unknown) was a charm[1][2][3] that prevented a person from cheating on a test or exam.[2][3]


"Now, I must warn you that the most stringent Anti-Cheating Charms have been applied to your examination papers."
Minerva McGonagall to fifth year students before the start of their O.W.L. exams[src]

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.[2][3] They could be circumvented with Cribbing Spells.[4]
