Non-staff teachers can't become full members directly, and they must participate in the open recruitment of teachers.

Open recruitment of teachers is an examination organized by the government, the Human Resources and Social Security Bureau and the Education Bureau to openly recruit teachers for the society.

The time of public recruitment examination in different provinces, cities, districts and counties is not uniform. The main examination subjects are "Basic Knowledge of Education" and "Professional Ability Tendency Test of Teachers' Open Recruitment Examination". As long as you pass the open recruitment examination and pass the interview, you will become a formal national teacher.
