The discipline of off campus training itself is not necessarily illegal, but after the implementation of the "double reduction" policy, it is illegal to conduct discipline training in violation of relevant regulations. The following explains in detail from different aspects: Compliance If an off campus training institution has obtained legal qualifications for running a school in accordance with relevant regulations, and conducts disciplinary training in a compliant manner within the specified time, then such training activities are legal. However, after the implementation of the "double reduction" policy, compliance training in disciplines is greatly limited. Illegality Training without permission: According to the Law of the People's Republic of China on the Promotion of Civilian run Education and other relevant laws and regulations, off campus training institutions engaged in disciplinary training must obtain school running licenses and other relevant licenses. If discipline training is carried out without permission, it is illegal. For example, some individuals or organizations privately set up academic counseling classes in residential buildings without the approval of the education department and other relevant institutions. Training beyond the scope: some institutions that originally obtained non discipline training qualifications carried out discipline training without authorization, which also violated the relevant regulations. For example, an organization that has obtained the qualification for art training privately offers courses in Chinese, mathematics and other disciplines. Training at illegal time: according to the "double reduction" policy, off campus training institutions are not allowed to organize disciplinary training on national statutory holidays, rest days and winter and summer vacations. If the institution violates this provision, it is illegal to carry out disciplinary training during the prohibited period. Implicit variation and violation training: some institutions or individuals, in the name of "high-end housekeeping", "crowdfunding private education" and "home teachers", conduct disciplinary training in violation of regulations to avoid supervision, which is also prohibited by law.
