However, the term public school has an entirely different definition in the UK education system. Public schools are perceived as the most exclusive and prestigious private schools in the UK, as well-known examples include Eton College, Harrow School and Wellington College. Most public schools are highly selective, as many contain boarding facilities for students as well. Such term is indeed highly confusing owing to the traditional definition of the word 'public' as academic institutions that are independent from the English church and government. Apart from public schools, the other two forms of fee-paying schools in the UK include private schools and independent schools. Whilst independent schools are overseen by a board of governors or trustees, private schools are run by the owners, thus are comparatively more selective. On the contrary, government-funded schools are labelled as state schools, as most provide education free of charge. Some students from state schools will also be selected to attend more academically-oriented secondary schools called grammar schools through the 11-plus exam. However, international students must have a British or European Union passport in order to enroll into a state school.
