The state is responsible for the management of churches and schools, requiring all degree applicants and all personnel of educational institutions to swear allegiance to the king and consciously accept the supervision and management of the state. However, compared with other Protestant countries, the British government and the Anglican Church are not enthusiastic about education. The establishment of schools is not the responsibility of the state and the church, but the responsibility of private organizations and charities. Because of this, the development of primary education in Britain lags far behind other Protestant countries. On the other hand, English has become the teaching language in primary schools. Middle schools in Britain are grammar schools, originally sponsored by the Catholic Church. After the Reformation, about 200 grammar schools were reorganized and established. Most of them are supported by private organizations and charities, and the urban bourgeoisie contributes the most. Some of these grammar schools are public schools. The teaching contents in public schools are mainly Latin and Greek. Nine public schools, including Eton College and Harrow College, are the most famous.
