Because I have no children, I just worked in Spark, and now I'm not in Spark. In my observation, every child of Spark will have a head teacher and two teachers to teach him. Because the class teacher will follow up the children's learning in Spark, and the teacher is only responsible for class. Because according to the requirements of the system, the class teacher needs to communicate with parents by WeChat and telephone within a certain period of time, such as after the first class, and after the last three classes, there will be a parent meeting, so the parent meeting will be very clear about the children's learning in Spark. But tutoring, in the final analysis, is the improvement of grades. In Spark, there will be some experienced teachers who teach for a long time, but your children may not be able to attend these teachers' classes. It depends on whether the class teacher helped you fight for it. In Spark, many of them are fresh graduates. These teachers are a little inexperienced, and everything else will do. When they first come out to work, they will actually feel more sorry for their children. Generally speaking, Spark is ok. But Spark said, after all, it needs to be profitable. Every class teacher has the task of renewing fees every quarter, and teachers get more for more work.
