Do employers take on-line college seriously when viewed on a resume?

Will you view on-line college degrees with respect?
Do you view or regard some more favorably than others?

Generally employers compare resumes they receive from a pool of interested candidates. If you're applying for a position where a college degree is a requirement, the employer will try to weight the quality of the edcuation you received and compare it to the other applicants. They may compare your school to other school's based on the quality of programs offered or the school's national standing. You may find Businessweek.com helpful in that respect, because they rank colleges and their programs annually.
Keep in mind that employers will look more at your experience and what you can bring into their organization versus what type of degree you have. A candidate with great past experience will have greater chances of obtaining most positions out there than a candidate with a portfolio of degrees and no experience.

It depends on the position and the school. But, generally, no. For a serious position, I would dismiss Devry, Phoenix Online, and their equivalents. However, if the degree is associated with a State school, I would consider it valid.

Naw, they figured you took the easy route. You'll certainly get hired, just not by the best companies nor for the best jobs.
