If you want to take the teacher qualification exam, there are both primary and secondary schools. Just refer to the materials and teaching materials you bought. Because the textbooks are totally different, but if the textbooks of high school and junior high school are the same.
When I applied for the program, it was like this: first, I registered at the corresponding test center. I applied at the local test center, usually the local normal college. Educational psychology is necessary and considered as a written part. After passing, you will go to the local education department to apply for lectures and other interviews. Generally speaking, you also need practical teaching experience, which requires your internship unit to prove that a formal and strict interview will also require you to plan your teaching for a period of time. When I applied for the exam last year, I asked to bring a teaching plan for the whole school year to the interview.
Of course, there will be differences because of different requirements in different places. You can consult the local education department carefully. Good luck. If you really refer to it, I hope you can pass it smoothly.
