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 therapeutic boarding schools which offer treatment for psychological difficulties. Special needs education for children are catered for in some boarding schools. Some boarding schools offer 'democratic education', such as Summerhill School (where pupils make many of the decisions). Others are determinedly international, such as the United World Colleges. Military schools or academies provide discipline, and may offer a way into military service. Gordonstoun in Scotland is a co-educational school for both day and boarding pupils.
Some famous novels use boarding schools as their setting. 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.
