Multiple colleges and universities across the United States offer online PhDs and professional doctorate degrees to help students reach their career goals.

The first are professional doctorates, which lead to specific careers or licensure. The others are research-based degrees, like Doctor of Philosophy (PhD) programs, which often lead to roles in academia and research.
