Ravenclaw values intelligence, learning, and wit. The house mascot is an eagle, and the house colours are blue and bronze (changed to blue and silver in the films). The head of this house is the Charms professor, Filius Flitwick, and the house ghost is The Grey Lady. According to Rowling, Ravenclaw corresponds roughly to the element of air. The founder of this house is Rowena Ravenclaw.

The dormitories are located in Ravenclaw Tower on the west side of the school. The common room, which went undescribed in the series until the climax of Deathly Hallows, is round and filled with blue hangings and fat armchairs, has a domed ceiling painted with stars, and also features a replica statue of Rowena wearing her diadem. Harry also notes that, by day, the Ravenclaws "would have a spectacular view of the surrounding mountains." A logical riddle must be solved in order to gain entry, whereas the Gryffindor, Hufflepuff and Slytherin common rooms only require a password.

Hufflepuff values hard work, loyalty, tolerance, and fair play. The house mascot is the badger, and canary yellow and black are its colours. The Head of this house is the Herbology teacher Pomona Sprout, and the house ghost is The Fat Friar. According to Rowling, Hufflepuff corresponds roughly to the element of earth. The founder of this house is Helga Hufflepuff.

The Hufflepuff dormitories and common room are located somewhere in the basement. The entrance is found behind a life-like painting that is somewhere near the kitchens. Students must give the password to the painting to enter. The Hufflepuff common room is filled with yellow hangings and fat armchairs and it has little underground tunnels leading to the dormitories, all of which have perfectly round doors, like barrel tops (very much like a badger sett).
