The minimum level of education required to become a Registered Nurse (RN) is an Associate Degree in Nursing (ADN). However, most aspiring nurses tend to opt for at least a Bachelor of Science in Nursing (BSN) degree, as more and more employers are now beginning to show preference for BSN graduates. According to the US Bureau of Labor Statistics, a BSN degree is the least amount of qualification required for administrative positions, consulting, research and teaching jobs in the field of nursing. Employers in hospitals may also require at least a bachelor’s degree in nursing for entry level positions.
