Do I have to pass Band 4 to be a teacher?

If you are a college student, you usually have to pass CET-4 to graduate. If you are an English major, the requirements may be higher, and you have to take CET-4 and CET-6, which is different from other majors. English teachers in normal primary schools, junior high schools and senior high schools need at least CET-4, and most of them will graduate in English. In that case, you need TEM-4 or CET-6. This is not necessarily the case if you do some English cram schools or some institutions that specialize in teaching English, such as IELTS and Canaan. Some institutions require you to pass their professional training or attend any certificate level. But CET-4 is easy to take, and it's not difficult at all. You can get through it if you work hard ~ ~
