Many employers require a 2-year degree and some require a 4-year degree. A license is required for this occupation, and many RNs work in specialized areas that require additional training or certificiation.
In order to take the California State Nursing Licensing Examination, one must first attend a nursing program that is accredited by the National League for Nursing and earn an Associate or Bachelor degree. Many RNs who start out with an Associate's degree later go on to earn a Bachelor's degree. A Bachelor's degree is required for many administrative positions and to enter graduate nursing programs in education, research, or a clinical specialty. Still, an Associate's degree is the quickest way to get licensed and working.
