The introduction of nine-year compulsory education is as follows:

Nine-year compulsory education is free for nine years from preschool to junior high school graduation. Nine-year tuition-free compulsory education has been tried out since 1986. The nine-year compulsory education system is a compulsory education for all school-age children and adolescents and a public welfare undertaking that the state must guarantee. There is no tuition and fees during the nine-year compulsory education, which is compulsory, free and universal.

The Compulsory Education Law stipulates that the period of compulsory education is nine years, which conforms to China's national conditions and is appropriate. Because there are still a few areas that implement eight-year compulsory education, that is, five years in primary school and three years in secondary school, these areas are also trying to realize the transition from eight-year system to nine-year system.

Nine-year compulsory education focuses on cultivating talents. Compulsory education is a universal, compulsory and free school education for all school-age children and adolescents according to law. It is the basis of improving national quality and the starting point of realizing social equity. Receiving compulsory education is the basic right of citizens, implementing compulsory education is an important duty of the government, and supporting compulsory education is the common task of the whole society.

Compulsory education has always been the top priority of China's educational reform and development. At the beginning of this century, China achieved the goal of popularizing nine-year compulsory education, and first solved the problem of "education" for school-age children and adolescents according to law.

After compulsory education is fully popularized and free, the state clearly regards the balanced development of compulsory education as the top priority of compulsory education, and strives to achieve the goal of "good study" for all school-age children and adolescents.

At the Sixth National People's Congress held in mid-April, 1986, the People's Republic of China (PRC) Compulsory Education Law was passed for the first time, and in July of the same year, nine-year compulsory education was formally implemented. After the implementation of the new Compulsory Education Law in September 2006, compulsory education was popularized throughout the country.

Nine-year compulsory education is the basis of improving the quality of the people, and it is also an important condition to ensure that all school-age children can go to school. As the starting point of realizing social equity, nine-year compulsory education is of great significance to improving the overall quality of the people, so it is the responsibility of every citizen to support the implementation of nine-year compulsory education.
