My first degree is animation, and now I am correspondence in primary school. I wonder if I can apply for the title of primary school art when recruiting teachers?

There should be no problem. Generally speaking, the evaluation of professional titles requires supporting materials related to your current job. So I want to remind you that if you are an art teacher in a primary school, you should only write a title evaluation paper related to art teaching in a primary school, and don't write the one with strong characteristics of your animation major (of course, there are some similarities between the two, but you should be inclined to art education in a primary school).
