Well, I only know that all registered XX teachers, except certified public accountants and students, are required to be qualified, and basically all need work experience. As for the professional qualification certificate, it seems that there is only a teacher qualification certificate, but the time arranged in each province is different. In the end, the university only took the soft exam of computer (the technical qualification (level) exam of computer technology and software), but it seems that students can't pass the advanced qualification in principle. This exam is in May and 1 1 month.
