This depends on the requirements of the training institution you are interviewing for. Some interviews can be successful as long as you have experience, but generally you don't need it. Individual professionals will need your qualification certificate or provide your professional certificate. Teachers in art training institutions are not required to have teacher qualification certificates in principle, but they must have undergraduate or junior college graduation certificates, and their majors are consistent with the subjects they teach.

To put it bluntly, if you teach painting, you must graduate from an art-related major and at least have a college diploma. However, there is also a situation in which some local education departments require managers of children's art training courses to have relevant professional qualifications (have held training courses), require a bachelor's degree or above, and of course need a teacher qualification certificate. In addition, there are requirements for credits and nationality. Different regions have different requirements for the establishment of off-campus training institutions. You should consult relevant local policies. But in fact, it will be safer to take the teacher qualification certificate, because more and more people in today's society demand academic qualifications. Just because your institution doesn't need a teacher qualification certificate now doesn't mean it won't be needed in the future. It will be safer to take one. Moreover, there are a wide range of teaching resources for the examination now, and non-normal majors can also apply for the examination, and the pass rate is also very high. Of course, if you don't want to take the exam, you can.
