There's a good chunk of people in that field, but if you find your niche and stand out, you'll go places.
Everything I've heard over the years about ITT Tech (including their own fine print on those commercials) makes me fully comfortable in telling you to stay the hell away from that organization.
It's a scam... and I don't think it's widely recognized as an accredited institution (or rather, its accreditation isn't widely recognized).
On the other hand.. some schooling is better than none? I know nothing of the other two institutions you've mentioned. I'm just saying.. be wary of ITT.
I'm on the audio side of production.. don't know much about the graphic side.
