The first category is those who are dismissed or dismissed for abusing students. These people can't be teachers. For parents, sending their children to school has great trust in teachers. What parents want to see is that teachers educate their students in a positive way. If they bully and abuse students, they will lose their qualifications as teachers.
The second category is people who have made serious mistakes and been punished by public security management. Teachers are prohibited from engaging in the teaching profession. Teachers should set an example for students, so even if the fault does not reach a crime, such people are still not suitable for the post of teacher. Even if they pass the teacher qualification certificate, it won't help.
The third category is people who have been criminally punished for intentional crimes. These people are banned from teaching. Teachers cultivate the flowers of the motherland and train groups of outstanding talents for the society. Only when teachers are qualified can they cultivate good students. When recruiting, the school will be very strict. Even if they make mistakes, they can't become teachers again. This provision is also a certain constraint. If they want to be teachers, they must be legal citizens.
The fourth category is the personnel who carry out other behaviors included in the scope of employment. Such people are also forbidden to be teachers. When the school recruits, it will open a pre-employment inquiry system. If the teacher has bad behavior, it won't work.
