While not all PhD programs can be offered online, there are quite a few which can. For example, someone looking for a medical degree cannot get it online since it requires a lot of hands on training. On the other hand things like business degrees or even PhD’s in technology can often be done either entirely or at least mostly online. Contacting institutions like Walden University or University of Phoenix to learn of how many different online PhD programs they have available is the best way to start the process of attaining a PhD.
