"Dualism" is generally called "Dualism" in Germany. "Dual system" vocational education means that teenagers receive vocational skills and related professional knowledge training in enterprises, and receive vocational professional theory and general cultural knowledge education in vocational schools. This is a vocational education system in which enterprises cooperate with schools and practice is closely linked with theory. The purpose is to cultivate professional and technical workers with high professional quality. Its main feature is that enterprises bear most of the funds and main responsibilities. Students who receive "dual-system" vocational education spend twice or more time in enterprises than vocational schools. Enterprises are the most important places to implement vocational education, and students are apprentices of enterprises.

Vocational schools are another part of dual vocational education. In Germany, due to the implementation of 12-year compulsory education, the German federal government stipulates that teenagers who have received 9-year compulsory education from the age of 6 must receive 3-year vocational compulsory education before reaching 18, that is, attend vocational schools. The number of vocational schools ranks first among vocational schools in German states.

While training enterprises, vocational schools teach young people the theoretical knowledge of vocational activities and help them to continue to develop in an all-round way. "Dual system" vocational education can also be said to be an important link between apprenticeship education and career in the pure sense, which avoids the problems caused by lack of employment experience and has a positive effect on young people and enterprises.

Over the years, enterprises receiving apprenticeship training have been accounting for about 20% of the total number of German enterprises, and the statistical data of 1990 is 5 13000 enterprises. The qualification of enterprise training is determined by the trade association, which has a special enterprise training consulting department. When an enterprise applies for vocational training, the enterprise training consultant of the consulting department needs to visit the enterprise face to face and discuss relevant issues with the person in charge of the enterprise. If the enterprise fully meets the requirements, the trade association will issue a notice of training license. Enterprises that fail to meet the requirements after examination shall not recruit apprentices without authorization. In many training enterprises, there are great differences in training due to different production scales. Large industrial enterprises like Audi generally have training centers and training workshops. Offering theoretical courses related to training occupation in enterprise training is a supplement and improvement of the knowledge and skills learned through practical operation in the training workshop, which is closely related to practice. Training enterprises not only have the training obligation to impart vocational knowledge and skills to apprentices, but also have the obligation to educate and care for them, that is, to care for their physical and mental health and cultivate their honesty, diligence, discipline, initiative, responsibility and creativity. Pay apprenticeship training allowance, and regularly let young people receive health check-ups.
