The ACCNS-AG, ACCNS-P and ACCNS-N credentials are entry-level advanced practice certifications for clinical nurse specialists (CNSs) educated at the graduate level to provide advanced nursing care across the continuum of healthcare services, from wellness through acute care.
Updated Study of Practice
AACN Certification Corporation regularly conducts national studies of practice, also known as practice analyses, to update and refresh certification test plans. These studies ensure that our exams are based on evidence, and the content of each exam is tied directly to relevant practice.
The most recent study of practice for the ACCNS-AG, ACCNS-P and ACCNS-N programs was completed in 2021, resulting in minor changes to the test plans and exams.
