You won’t find what you’re looking for here in Taiwan. Best bet is to go home and do it.
If you are dead set on being an administrator back home you’re best bet is to go home and get started now. I know all states are different but I think most require you actually be a teacher before you move into any kind of admin role. Hopefully you’re a licensed teacher at home at the very least already. Otherwise you have a long road ahead of you. You have to get certified in the state you want to teach, do your time in the trenches, I’d say at least 5 years before you can even think about applying for vice-principal jobs, and get that education admin degree. Your time throwing the sticky ball at Happy Kids Buxiban won’t mean anything when applying for admin jobs by the way. Your local experience will mean everything.
My father has been a principal for over 15 years, before that he was a teacher for 10 years.
