Colorado Technical University

Do you accept an online diploma or degree in America? I noticed a link "Get your degree in 1 year" on Yahoo! main page.Those schools include aiu online,KAPLAN UNIVERSITY,DeVry University,SAINTLEO UNIVERSITY,STONECLIFFE COLLEGE ONLINE,Colorado Technical University Online,University of Phoenix. Does a American usually accept those diploma?And which school do you prefer?

How do I check whether or not a colleges credits will transfer to major universities w/o asking said college? My friend is attending online for Stonecliffe and all we can find for information is on their website. Where else does one look to find out about a colleges viable accredidation?
