Is it necessary to have a medical qualification certificate before becoming a school doctor? When a medical student becomes a doctor, can he still get a doctor's qualification certificate?

There are two kinds, one is the infirmary of primary and secondary schools, without the permission of medical institutions. It is mainly for students to manage health examination files, cooperate with professional medical institutions to check and attend human health classes, which doctors, nurses and non-medical personnel do not need to do. The other is that schools and hospitals, such as colleges and universities, must have the license of medical institutions, and doctors must be medical practitioners. Generally, they recruit certified doctors from outside the school, not fresh graduates, because no one teaches you. What's the use of not working? When you go in, you can't learn anything, even you can't get into the medical examination. It's very sad to die doing exercises.
