In the national education system, high school is a special stage. It is not only an important link between nine-year compulsory education and higher education, but also a critical period for students' personality formation and independent development, and it is also a basic project to improve the overall quality of the people and build a strong country with human resources.

Popularizing high school education is an important strategic decision made by the CPC Central Committee and the State Council in the decisive stage of building a well-off society in an all-round way. The Fifth Plenary Session of the 18th CPC Central Committee proposed "popularizing high school education". The Outline of the National 13th Five-Year Plan for Economic and Social Development lists the popularization of high school education as a major project of educational modernization. Popularizing high school education is an important measure to further improve the overall quality of the people, the competitiveness of the labor force and build a strong country with human resources after popularizing nine-year compulsory education in China, which is of great significance and far-reaching influence.

In recent years, China's high school education has made great progress. In 20 16, the gross enrollment rate of high school education reached 87.5%, and the popularization level reached a new level. Popularizing high school education is also conditional.
