Then, we can take a look at the expanded content in this respect: from the concept of teaching aid application, in our country, applying for teacher qualification certificate needs to take a series of exams such as social certification examination, which is the three certificates explained in the previous paragraph. If you get the teacher qualification certificate, according to the regulations, in-service teachers need three certificates for continuous service, namely, academic certificate, teacher qualification certificate and admission notice. This is normal. In this society, education is a stepping stone, so it is required. It is unrealistic to go to work and teach junior high school children knowledge after graduating from junior high school. Teacher qualification certificate is a passport to education. If there is no teacher qualification certificate, the school may not accept it. Even if accepted, it's quite "driving without a license". Schools and teachers who employ teachers should bear certain responsibilities.
