Apply for qualification certificate
If you are not a normal college student, you must apply first, and you need to apply to the competent education department (to the local education bureau or the education bureau where your household registration is located), and then complete the registration application procedures, such as filling out forms, paying fees, and providing all kinds of qualifications required for the application (you can consult them if they are originals or photocopies).
Awaiting approval
Then, according to the relevant requirements, if you have all the conditions, you just need to wait for the approval process to be completed; If the conditions are not enough, you need to take the corresponding exam. You can ask them about subjects, time, place and other matters needing attention.
give a trial lecture
As far as I know, if it is only textual research, it may not be necessary; If you want to apply for a teaching position, you must go through this "trial lecture" procedure.
Educational qualification
Applying for the corresponding level of teacher qualification certificate requires different academic qualifications. As far as the current situation is concerned, the qualification certificate of senior middle school teachers must have a bachelor's degree or above recognized by the education department; Junior high school teacher qualification certificate must have a college degree or above recognized by the education department; Primary school teachers' qualification certificate must have a technical secondary school degree or above recognized by the education department.
Consulting education bureau
The most realistic problem is that you'd better consult the local education bureau or the education bureau where your household registration is located first, so that you can know the true, accurate and specific situation. Good luck!
