In the recruitment of professional teachers, candidates have to go through three levels: first, the principal level: the principal personally conducts professional and related investigations and inquiries on the candidates. The second is the professional teacher pass: let the senior teacher * * * check. The third is trial teaching: to assess their professional ability, teaching ability and communication ability with students. Every teacher is not only a preacher, but also a person who needs constant self-improvement and self-improvement. If you don't practice by yourself, you are often inferior to others. After a long time, your hands are rusted, and your skills are ultimately inferior to those of people or even students. This kind of teacher will lose prestige and respect in the eyes of students. To give students a bowl of water, the teacher should have a bucket of water or even a lake. Therefore, we attach great importance to the self-training of professional teachers every year: after each art college entrance examination, professional teachers should have at least three months of intensive training.
