A boarding school is a school where students live and sleep. Some boarding schools have day students who go home at the end of the school day. If the school costs money, they don't have to pay as much money. A person who stays at a boarding school is called a "boarder". In the UK 1% of children go to boarding schools and 13% of private school pupils are boarders. Most boarding schools are private. This means that as well as having to pay to sleep there, students have to pay for their education.
There are a lot of famous novels that take place in boarding schools. Examples include the Harry Potter series by J.K. Rowling; A Little Princess by Frances Hodgson Burnett; The Catcher in the Rye by J.D. Salinger; the Malory Towers, St. Clare's and The Naughtiest Girl series by Enid Blyton; and Nicholas Nickleby by Charles Dickens.
