Teachers' recruitment examination generally has certain restrictions on candidates' majors, which is to ensure that teachers' professional quality and teaching ability can meet the needs of education and teaching. The following are some common occupational restrictions:

1. Education-related majors: Generally, candidates are required to have a bachelor's degree or above in education, psychology, education management, preschool education and other related majors. These majors can provide knowledge and skills in teaching and education management, and help candidates better engage in education.

2. Discipline-related majors: The recruitment of teachers in specific disciplines will have more specific requirements for candidates' majors. For example, a math teacher needs a background in math or math education, and a Chinese teacher needs a professional background in Chinese, language and literature or teaching Chinese as a foreign language. This is because subject teachers need to have the knowledge and teaching ability of corresponding subjects.

3. Teacher's major: Teacher's major is a major specially set up to train teachers and education professionals. In some areas, the teacher recruitment examination may give priority or extra points to the candidates of normal majors.

Please note that different regions and schools may have different requirements for teacher recruitment. Specific restrictions and requirements are subject to the recruitment announcements of relevant local education departments and schools. If you have specific recruitment questions, I suggest you consult the relevant recruitment agencies or education departments for detailed information.
