This page is for keeping track of characters that were Prefects, Head Boys/Girls, and Quidditch team members during their days at Hogwarts. There are a lot of characters that claim Prefectships and team positions (including captain) in their backgrounds, and we've found that we need to keep it all straight. The years listed below are graduating years (so a Prefect listed for 1921 was in their Fifth Year in the 1918-1919 school year).
