"....The Sorting is a very important ceremony because, while you are here, your house will be something like your family within Hogwarts. You will have classes with the rest of your house, sleep in your house dormitory and spend free time in your house common room." McGonagall, Harry Potter and the Philosopher's Stone.

Prefects:

Making up about 24 students of years 5 through 7, roughly 6 per house and 8 per year, the Prefects are much more commonly seen and interacted with by most students than the Head Boy and Head Girl. They, like the Head Boy and Head Girl, are responsible for the welfare of their fellow students, and are generally trusted and high-achieving students. Like the Head Boy and Head Girl, they have the ability to add or deduct modest amounts of points in order to better aid them in helping to manage the large number of students. Not every low point or triumph will occur under the eye of a teacher.

The Head Boy and Head Girl are 7th year students, though rarely are they in the same House. They act jointly as the heads of the Prefects in addition to sharing the same responsibilities to the welfare of all of the students. In the case of a crisis severe enough to demand the attention of the entire teaching staff, the Head Boy and Head Girl are placed in charge of directing the Prefects (generally in the task of getting all of the students to a safe area, such as their House Commons).

Prefects and Head Boy/Head Girl are considered feature characters but they are not available through application. These roles are handed out by the help staff at the beginning of each IC school year to players who are active, reliable, and responsible.
