Foreign teachers: to measure whether English teachers are professional or not, first of all, the pronunciation of foreign teachers is pure or not. Secondly, it depends on the qualifications of foreign teachers in English teaching, whether they have the qualification certificate for International English teaching, and whether they have rich experience in English teaching.
Mode: parents should have some knowledge of the English teaching mode in the market, one-to-one, one-to-two and small class. These modes are not absolutely good or bad, mainly depending on the personality characteristics of the children.
Scale: all training courses are now optimizing teachers, expanding brands and improving cost performance. The industry has a good overall development space. There are a lot of offline one-to-one English training, and some small-scale training courses are very good, but I suggest that it is more secure to choose a certain scale training course for children.
