To become a CNS, one must first become a registered nurse (RN) by earning a bachelor's degree in nursing (BSN) and passing the NCLEX-RN exam. After gaining clinical experience, the next step is to pursue a master's or doctoral degree in nursing with a specialization in a particular area of practice. CNSs must also obtain certification through a recognized certifying body, such as the American Nurses Credentialing Center (ANCC).
