First, divide the education stages according to the law of physical and mental development of school-age children. The educational stages in the "633 academic system" are basically divided according to the characteristics of China teenagers' physical and mental development, which is the first time in the history of the development of modern academic system in China.

Second, the primary education stage tends to be rational and more pragmatic. It shortens the period of primary school from seven years to six years, and the primary school is divided into two levels, four years for compulsory education and two years for senior primary school, which is conducive to popularizing primary education. Kindergartens have also been brought into the primary education stage, which connects preschool education with primary education and establishes the position of preschool education in the history of education in China.

Third, the secondary education stage is the core of the system reform and the essence of the new academic system. (1) The length of secondary school is extended from four years to six years, which improves the level of secondary school education, overcomes the shortcoming of poor basic knowledge caused by only four years of secondary school in the old academic system, and improves the connection between secondary school and university. The middle school is divided into junior high school and senior high school, which not only increases the flexibility of local schools, but also increases students' choices. (3) Middle schools implement the system of selecting subjects and dividing subjects, so that students have more room for development and meet the needs of students at different levels of development.

Fourth, the new academic system has strengthened vocational education, the most obvious feature of which is to give consideration to further studies and employment. For example, in the advanced stage of primary school, it is required to consider local conditions and increase vocational education preparation; Offering various vocational courses in middle schools enables students to prepare for further study and find jobs as soon as possible.

Fifth, in normal education, we should increase the types, increase the degree accordingly, and set it flexibly. (1) In the secondary education stage, teachers' schools have studied for six years, and the last three years of teachers' schools implement the group selection system; (2) Normal schools can recruit junior high school graduates two or three years after their establishment; (3) In the stage of higher education, the still-established higher normal school will be changed into a normal university, and an education department will be set up in the university to recruit graduates from higher normal schools or middle schools.

Sixth, in the stage of higher education, shortening the length of higher education and canceling the pre-university courses will make universities no longer undertake the task of general education, which is conducive to professional education and scientific research.

In addition, there are two "supplementary provisions". First, we should attach importance to the education of talents, change the length of study and courses, and let excellent intelligence develop as much as possible; The second is to attach importance to special education.
