How do Hogwarts students get chosen?
Hogwarts students don’t get chosen. They are accepted into Hogwarts if they are wizards or witches. As soon as they come of age they receive a letter of acceptance and a list of school supplies signed by Professor Minerva McGonagall. They then go to platform 9 3/4, which is a wall only wizards and witches can through, between platforms 9 and 10. Once the students are at Hogwarts, the sorting ceremony begins and the Sorting Hat puts them in their appropriate house by looking through their minds and seeing which house they would do best in.
