The selection process for Hogwarts School of Witchcraft and Wizardry is a unique one, with only two items being used to determine who will be accepted. These items are the Quill of Acceptance and the Book of Admittance.
The Quill of Acceptance is a small silver inkpot with a long, faded quill protruding from it. This quill is enchanted to detect magical potential in a person. When a person writes their name with the quill, it will turn scarlet if they have magical potential. If the quill does not turn scarlet, then the person is not eligible for admission to Hogwarts.
The Book of Admittance is a large book bound in peeling black dragon-hide. It contains the names of all those who have been accepted to Hogwarts. When a person’s name is written in the book with the Quill of Acceptance, it is added to the list of those accepted.
The selection process for Hogwarts is a very special one and is used to ensure that only those with magical potential are accepted. It is a unique system that has been in place for centuries and is a testament to the importance of magic in the wizarding world.
