The British secondary school system adopts a two-track system, with a grammar for the middle class or a comprehensive school for the working class, and a public school for the nobility. Public school is the institution in which British royal family students receive education in public places. It is a so-called private aristocratic middle school. Although it is public school, it is run by private individuals, but schools can openly recruit students, not just children of specific religions, races or regions. Tuition fees are extremely high, and usually only affordable to the upper class of the society, accounting for less than 7 percent of the UK's educated population, mostly for the royal family. Public education is aimed at cultivating future ruling class talents with militarized management. Taking knowledge and knowledge as the first priority of education, it has created countless first British leaders or scholars.

British public school can be divided into nine major factions in 1861, including Charthouse College, Eton College, Harrow School, Merchant Taylors' School, Rugby College, St Paul's School, Shrewsbury Li School, Westminster College, Winchester College. By 1902, the British Government Yearbook listed 102 more well-known public schools, and divided the schools into five grades, showing the distinct class at the time. Most of the public students will choose to enter the university around the age of 19. At present, public school has become an elite education in the UK, and it has a high status in the entire British education system. Each school has its own management style, and the students are outstanding.
