A top-down track, its structure is-universities (later including other institutions of higher learning) and middle schools (including middle school preparatory classes).

The other track is bottom-up, and its structure is-primary school (later primary school, middle school) and its subsequent vocational schools (first primary vocational education connected with primary school, then secondary vocational education connected with junior high school).

The core of modern education system is school education system, which can be divided into single-track education system, double-track education system and sub-discipline education system.

Extended data:

In western Europe in the 18 and 19 centuries, under the influence of social, political and economic development and specific historical and cultural conditions, both academic modern schools and mass modern schools for working people's children have been fully developed at the same time, thus forming a dual-track educational system of modern education in Europe: one from top to bottom and the other from bottom to top. They are two parallel series, which are neither connected nor linked, thus depriving the children of working people studying in national education schools of their right to enter middle schools and universities.

The dual-track academic system stipulates the nature, tasks, admission conditions, study years and the relationship between them. The education system is restricted by the development level of social productive forces, science and technology, political system and ideology, population development and psychological characteristics of teenagers. From the analysis of vertical school system, the double-track school system is developing towards branch school system and monorail school system.
