In the Harry Potter series, the Sorting hat places people in their respective houses at Hogwarts Wizarding school.

Ever year, it sings before sorting, and describes each house. A student is placed in their house for their entire time at Hogwarts, where they are like family.

Or yet in wise old Ravenclaw,
If you've a ready mind,
Where those of wit and learning,
Will always find their kind
-From the Sorcerer's Stone/Philosopher's Stone.

For the Goblet of Fire:

Fair Ravenclaw, from glen...
For Ravenclaw, the cleverest
would always be the best
Ravenclaw was one of the four founders of the school. Cho Chang(Harry's crush) is the Seeker for the Ravenclaw Quidditch Team. Most Harry Potter fans choose to be in Gryffindor in fan fiction and online clubs.
