From the middle of19th century to the middle of 20th century, the British government attached great importance to the development of primary education. As early as 185 1, the Congress of Charter Movers put forward a resolution to implement universal compulsory education. In order to meet the needs of Britain to cope with international economic competition and improve the quality of its citizens, the British government promulgated and implemented the Primary Education Act in 1870: the Act requires compulsory primary education for children aged 5- 12. The promulgation and implementation of the Primary Education Act marks the formal formation of the British primary national education system. In order to further promote the development of primary education, 19 18 "Primary Education Law" established preschool classes for children aged 2-5, and at the same time increased the length of compulsory education to 5- 14. During the period of 1926- 1933, the Labor Party government issued three reports on youth education, known as the "Hado Report". The report makes the following provisions for the development of primary education: extend the period of compulsory education to 15 years old; 1 1 Children's education is primary education, which is provided by two institutions. Children aged 5-8 go to preschool, and children aged 8-1/kloc-0 go to primary school. The recommendations made in the Hado report have not yet been realized. The Butler Act of 1944 sets the age of compulsory education at 5- 15, and reiterates that local education authorities should set up preschool schools for children aged 2-5.
