<p>Yes, it is important to indicate that you are Appalachian. This is a well-recognized regional cultural minority group in the US. I don’t know if you are bi-dialectal (do you speak Appalachian English at home and Standard American English at school?), but many people in your region are. This kind of stuff is interesting to college admissions and scholarship committees because most of their “white folk” come from the suburbs. You would bring a somewhat different perspective to the classroom. If you need help with your paperwork, go back to that English teacher and ask for more specific advice.</p>
