Freshmen and sophomores can't get the teacher qualification certificate because the original teacher qualification certificate is valid for life, but after the reform, they will get the qualification certificate through the written test and interview of the teacher qualification certificate. The term of this qualification certificate is 3 years. The teacher qualification certificate needs to be handled at the designated institution within 3 years, otherwise the certificate will expire and students need to take the exam again.
However, the identification of teacher qualification certificate can only be applied by students in graduation grade, which means that undergraduate courses can only be identified in senior year. Freshman passes the written test and interview of teacher qualification certificate, and senior is easy to expire; Besides, there is a trial. If students fail, they need to apply from the beginning. This risk is too high for students. It is best to take the teacher qualification exam in the third year, so that students will have more time.
Teacher qualification certificate is the threshold to enter the teaching profession. You can't be a teacher without a teacher's qualification certificate. At present, the gap of teachers in China is still very large. Because the teaching profession is relatively stable and the work is not so complicated, this is also a way that college graduates are willing to consider when looking for a job.
