Requirements for teacher qualification examination
According to the current Regulations on the Management of Teachers' Qualifications, primary school teachers should have at least technical secondary school (junior college) education, and junior high school teachers should have college education or above. Each teacher can only hold one kind of teacher qualification. If you successfully pass the junior high school teacher qualification certificate, then the primary school teacher qualification certificate will not be retained.
Preparation material recommendation
When preparing the teacher qualification certificate, you need to master the basic knowledge of pedagogy and educational psychology. I especially recommend pedagogy and educational psychology published by East China Normal University as your study materials.
Choose a professor's topic
When choosing a professor's subject, you must consider your academic qualifications and professional background. For example, if your junior college degree is Chinese major, you'd better choose to teach Chinese in junior high school instead of history, so as to ensure your professional counterpart and lay a solid foundation for your future job title evaluation.
