A research project culminating in a Doctor of Philosophy (PhD) degree typically takes 3-6 years from time of enrollment depending on transferred credits, prior completion of a MS degree, and pace of research. Graduate students who enroll without previously completing a MS will often complete the requirements and earn an MS degree on the path to their PhD.
Although PhD degree programs are more varied in schedule in comparison with MS programs, this document provides a Gantt chart illustrating one example of a research timeline in which the student also completes a MS degree. Note that thesis and graduation deadlines are approximate, and you are responsible for knowing and meeting deadlines specific to your degree.
