An associate degree in nursing (ADN) represents the minimum level of education required to work as a nurse, and so RNs with an ADN typically work in entry-level nursing positions. A bachelor's of science in nursing (BSN) is the next level up from the ADN and offers, in general, higher pay and more opportunities, including advanced clinical nursing positions. Many employers prefer nurses who have developed and honed their skills, and getting a BSN is often faster than working your way up through experience. Having a BSN also makes it easier to continue your education later if you choose to do so.
