As long as teachers, whether full-time or part-time, need training, which is necessary and the most stringent. In addition, for teaching assistants, you need to see what kind of teaching assistants they are, such as teaching assistants in summer camps and winter camps. These all need training, but this is vocational training, not teacher training. Who dares to take you if you don't take part-time training? Haha, training is necessary, and training is also an opportunity to exercise. To put it bluntly, you shouldn't go without training.
