I think I told you before, but SCAD is hands down the best place for art ed IMO. I know SO many people who have gone there, if not for formal education for learning a few things here and there. One of my fave art teachers in high school graduated from SCAD. She told me I should go there. When I saw her a year ago I told her I was thinking about going to grad school to be an art teacher and she told me again, SCAD SCAD SCAD. I wish I could, I really honestly do. If I had my pick of ANYWHERE in the world... that's where it would be.
SCAD also does distance learning now but I'm not sure how well that would really work. I don't doubt that if there's an innovate, amazing way to do it, SCAD has found it, but on campus learning would likely be far more wonderful.
OTOH there's also Art Institute of Chicago, which I have considered in the past - and then I'm only about three hours south so we could go tear up Chicago with our fab little dogs. ;D I believe there are other art institutes in other locations, but I have heard people say Chicago is really unique and probably the best.
Myself, I just took art classes at community college and I've done some seminars/workshops the local uni offers, but my major when I was getting my BA was not actually art, so I didn't really have the opportunity to take more art classes. My mom works at the com college now so I can take one free class every semester, and I am seriously thinking about taking a few studio classes since I can... it's been a while since I set foot back in the studio at the community college, but when I'm there in that environment, I feel inspired again. It's wonderful what just being in that environment can do.
