Summerhill School is an independent boarding school in Leiston, Suffolk, England. It was founded in 1921 by Alexander Sutherland Neill with the belief that the school should be made to fit the child, rather than the other way around. It is run as a democratic community; the running of the school is conducted in the school meetings, which anyone, staff or pupil, may attend, and at which everyone has an equal vote. These meetings serve as both a legislative and judicial body. Members of the community are free to do as they please, so long as their actions do not cause any harm to others, according to Neill's principle "Freedom, not Licence." This extends to the freedom for pupils to choose which lessons, if any, they attend. It is an example of both democratic education and alternative education.

A boarding school is a school where pupils live within premises while being given formal instruction. The word "boarding" is used in the sense of "room and board", i.e. lodging and meals. As they have existed for many centuries, and now extend across many countries, their functioning, codes of conduct and ethos vary greatly. Children in boarding schools study and live during the school year with their fellow students and possibly teachers or administrators. Some boarding schools also have day students who attend the institution during the day and return home in the evenings.
