Head of House

At Hogwarts School of Witchcraft and Wizardry,a Head of House is a teacher responsible for one of the four Hogwarts Houses.It is possible for a Head of House to serve concurrently as Deputy Head but not as Head of the school.

A Head of House must have been a member of that House while a student at Hogwarts.It is possible that a shortage of teachers who had been in Slytherin after the First War paved the way for Severus Snape to become Head of that House at a remarkably young age for such a position.On the return to the Hogwarts Faculty of Horace Slughorn,who had been Head of House when Snape was a student,Snape jealously guarded the prerogatives of the Headship.

A Head of House is in charge of discipline over its students as well as making decisions regarding the House's Quidditch team.

The precise mechanism by which they are chosen is not known.
