No, of course not. Remember a principle, the teacher qualification certificate of high school can teach lower classes, but the premise is the same subject. For example, high school Chinese teacher qualification certificate can teach primary school and junior high school Chinese, high school mathematics teacher qualification certificate can teach junior high school and primary school mathematics, but junior high school physics teacher qualification certificate can only teach junior high school physics, because there is no physics class in primary schools. If you want to teach primary school mathematics, you can only take the math teacher qualification certificate. Please pay attention to the official account of WeChat for the teacher qualification examination: teacher recruitment group.
