House heads could make a short quiz every so often. Repeated facts, sure, but chances to learn. Other house heads could complete them to get points for their own house, and it could rotate through so there's even chances. All quizzes could be given to our lovely headmistress so there can't be any unfair scoring.

I would love to help come up with some questions, if I just knew what you already had.
