If you want to work in a kindergarten, you can take a teacher's qualification certificate and a nurse's certificate (it seems to be this), and then the most important thing is that you should learn art, dance, singing and piano, and you can take such classes outside. For example, you can consider taking the piano exam. Singing is mainly to learn the basics, and dancing is just to find a class to train art before the college entrance examination. Art sketch and color have a foundation.
At present, a better kindergarten enrolls undergraduate students, and this science major is particularly rare, so now a better kindergarten enrolls art undergraduates with similar majors in art, dance, vocal music and piano. So, if you want to learn, try to learn what I said.
I don't know if I have made up classes before school starts. I think it's much better for you to study those specially than to find a teacher to teach you before school! Although I am not a preschool teacher, many of our preschool teachers, to tell the truth, mainly train students in secondary and higher vocational schools, which are not comparable to professional art students. This is also a fundamental reason why kindergartens are willing to recruit art students instead of students who graduated from pre-school higher vocational colleges. What I learned before going to school is not refined, but only superficial knowledge. If you are proficient in what I said above, you will have an advantage! Besides, you graduated from college!
