Approved list of schools
here.
And just because you got an aviation degree from an approved school in the past doesn't mean that you'll qualify for the 1,000 hour R-ATP. I got my degree back in 2005 and after contacting my university and getting the certificate needed to prove that I qualified for it, it showed that I only had enough qualifying credit hours for the 1,250 hour R-ATP even though I got a 4 year degree. Since the whole R-ATP thing didn't exist back then, they couldn't tailor the courses to meet the requirements that the FAA laid out for the R-ATP, and apparently they're pretty strict on what a course must contain for it to qualify.
Just putting that info out there since it caught me by surprise.
