Is the highschool transcript a crucial part of admission to an art school?

I'm planning to go to art school and i'm just wondering if these schools are paticular about the content of the highschool transcript. I've done a lot in high school, but i've been homeschooled and I am not strong in academics. So I cannot list all the ';typical'; classes on my transcript. Would this be a problem for trying to get into an art school. Apart from the academic side, i have potential and i am passionate about art and I am not lazy.Is the highschool transcript a crucial part of admission to an art school?
I only know about music schools, but I'd assume it'd be similar. It depends a lot on the school. Some of them are soley interested in your talent. Others, especially liberal learning schools, care about your achademics too. Some have minimum requirements for acceptance (but some of this schools are willing to make a ';mistake'; in your benefit if they really like you). I would look at and talk to the specific schools you're interested in to see what their policies are.
