Master's degree programs for RNs with a bachelor's degree generally take 1-3 years to complete, depending on the school and the specialty. Graduates with a non-nursing bachelor's degree have the option of enrolling in a BSN-to-master's degree fast-track program.
Registered nurses who only took an associate degree in nursing or got a nursing diploma, both of which take less than four years to complete, may be required to go back to nursing school to earn their BSN degree before they can be admitted to medical school. Medical school often takes four years to complete.
