At any stage of education, it is not necessary for parents to approve the suspension of students. Compulsory education stage and high school, university and other education stages have different requirements for students to drop out of school because of injury, so the suspension that the school does not recognize must be the injury of students, so it is not necessary to drop out of school and they can go to school normally.
If your son has a broken bone, the hospital will give you a suspension certificate, because we need to have a suspension certificate, and the hospital will advise your son how long to suspend school. If it takes a long time to recover, the hospital will definitely tell you and issue such a certificate of suspension. With such proof, you can go to the education bureau to go through the formalities of suspension.
