FINDING AN ONLINE Ph.D. IN ENGINEERING

An online Ph.D. in Engineering is a research-based terminal degree. While earning your Ph.D. can open up new career opportunities and qualify you for higher-paying positions, you'll need to make sure that the program you choose is right for you. Ph.D. programs are available with many different concentrations, there are options for mechanical engineering, environmental engineering, aerospace engineering, and more. Many programs on this list take at least three years to complete while some can take as many as five years. The programs in this ranking are rigorous, and some require that you maintain a minimum GPA throughout the program in order to stay enrolled.

While the programs in this ranking do offer flexibility for working professionals, they each have a bit of a different design. Some programs are delivered entirely online while others require on-campus intensives each semester or even every month. Because these programs are research-intensive some programs require that you live within the state and perform research at approved facilities. You will also find variation in how online courses are delivered, with some programs offering asynchronous classes while others require you to be online at certain times on certain days for interactive coursework. It's important to think about the type of program that would best fit into your schedule while also delivering the quality education that you seek.
