The way I read this is, if you have a bachelor's in say English or Art, you better have a teaching certification plus they want you to have at least a little science accreditation. But if your bachelor's is in Zoology, they will overlook the lack of a certificate.
I am not sure how it works in Michigan, but I know private schools often don't require a teacher's certificate, whereas public ones absolutely do (except in substitute teachers). Now you called this school a charter school, my guess is that means it is more similar to a private school even if it is part of the state system.
Good luck. I bet you'd be a great zoology teacher!
