Public colleges and universities are only secondary schools, which are funded by the state. Generally, there will be state subsidies for studying in such schools. Facilities and equipment are also relatively backward, and they can hardly learn any skills, but they can go to school with their peers.
Enterprises contract public universities. Many secondary schools can't recruit students because they can't continue to operate, so enterprises have contracted down. The teachers in this school facility are ok, but there is a fatal shortcoming. The essence of an enterprise is profit, so it is lucky to meet a good principal.
There is also a private non-enterprise vocational technical school, knowing that teachers can learn skills in a field, but the tuition will be more expensive. Can be understood as a private school. Private schools are very expensive now, and teachers are accountable. Like private schools, the enrollment rate is unique. The employment rate of this school is unique, but we must distinguish between schools and institutions.
Evaluating the quality of a technical school mainly depends on employment.
