Prove that normal students are trained. After four years of study, you can get the teacher qualification certificate directly without taking the exam. Non-normal students also have to take the exam. You can not be a teacher with a certificate, but you must have a certificate to be a teacher. Normal students will study pedagogy and psychology at school, and they can pass the final exams of pedagogy and psychology at school, and they will take up their posts directly with certificates after graduation. Non-normal students have to wait until they take the teacher qualification exam every year, and then take the exam by themselves and teach themselves pedagogy and psychology. In short, normal students can be said to get the teacher qualification certificate naturally after graduation.
