Training colleges are generally not public institutions, and most of them are private schools. Private schools are not public institutions, but profit-making enterprises. Teachers in private schools are not prepared and belong to enterprise employees.

Private schools include private schools and private educational institutions that implement cultural education such as academic education, preschool education and self-study exams, as well as private schools and private educational institutions that implement vocational qualification training and vocational skills training.

Private schools have three obvious characteristics:

1. The organizer is not a national institution.

2. The funds come from non-state-owned financial funds.

3. Running a school for the society means recruiting students and students for the society and serving unspecified groups and individual citizens, not just recruiting people from a certain group, enterprise, industry, system and specific groups as students or students.

From the reality, the organizers of private schools mainly include: individual citizens, private enterprises and individual industrial and commercial households, collective economic organizations, state-owned enterprises, institutions and social groups. From the source of funds, there are personal self-financing, personal intellectual investment (no capital investment), personal and enterprise investment, fund-raising or shareholding, donation and so on.

For a specific private school, the source of funds is not completely single, but a mixture of individual, collective and enterprise funds. At the same time, non-financial funds do not rule out the injection of state-owned assets.
