University teachers can switch to teaching junior high schools, but they need to have corresponding academic qualifications and work experience. In China, the qualifications and grades of teachers are recognized and awarded by the national education department. If a university teacher wants to switch to teaching junior high school, he needs to pass the corresponding examination or training and obtain the qualification certificate of middle school teacher issued by the education department. In addition, the education department also requires teachers to have certain subject knowledge and teaching experience in the corresponding subject areas. Therefore, university teachers need to have the education background of middle school teachers and the corresponding subject knowledge and teaching experience when they switch to teaching junior high school.
