On the premise of having a teacher qualification certificate, you can take the teacher exam in the next semester of your senior year, so you can start working next semester. However, it should be noted that the recruitment requirements must have a diploma, which is not necessarily available at the time of registration, but it must be available at the time of registration: the preparation for the exam can be 3-6 months before the exam, and the specific exam time can be inquired in the local recruitment announcement. The open recruitment of teachers is announced at the same time with local institutions, and the situation of teachers preparing for exams in different regions is different. In some places, there is no fixed time, and in some places, there will be a fixed unified exam. The teacher recruitment examination is not unified nationwide, so the recruitment announcements are issued in different places, even in different cities in the same province.
