A Bachelor of Science in Nursing (BSN) is a four-year degree that requires no previous experience in nursing.
If you have a Bachelor's Degree from a liberal arts college that is not in nursing, you may earn a BSN as a second degree in two years or less in an accelerated program, depending on the prerequisite classes you have taken.
Most people who enter the field of nursing earn either an ADN or BSN.
Those who have earned an ADN may take more classes to earn a BSN through an RN-to-BSN program.
