There are three typical educational paths to registered nursing—a bachelor's of science degree in nursing (BSN), an associate degree in nursing (ADN), and a diploma. BSN programs, offered by colleges and universities, take about 4 years to complete. ADN programs, offered by community and junior colleges, take about 2 to 3 years to complete. Diploma programs, administered in hospitals, last about 3 years. Generally, licensed graduates of any of the three types of educational programs qualify for entry-level positions as a staff nurse. There are hundreds of registered nursing programs that result in an ADN or BSN; however, there are relatively few diploma programs.
