Given that many online learning colleges (and even online programs at community colleges and 4-year colleges) do not have permanent faculties (or do not use the permanent teachers for the online program), it’s especially important to check out the credentials of the person teaching the course. Look for the instructor bio on the course Web page. Check out his or her degrees (the higher the better), teaching experience (how many years, at what level), and whether he or she is trained in the field you’re going to take. And, if the info isn’t there, send an e-mail (polite, of course) asking a few questions about the instructor’s background. A good instructor should not take offense and should have nothing to hide.
