In 1975, AACN Certification Corporation was established as an independent 501(c)(6) corporation to promote and enhance consumer health and safety by establishing and maintaining high standards of professional practice excellence through certifying and recertifying nurses in the care of acutely and critically ill patients and their families.
Guided by a nine-member board of directors, AACN Certification Corporation develops and administers the CCRN, PCCN, ACNPC-AG, ACCNS-AG, ACCNS-P and ACCNS-N specialty certification exams, and the CMC and CSC subspecialty certification exams.

Ethics
AACN and AACN Certification Corporation consider the American Nurses Association (ANA) Code of Ethics for Nurses foundational for nursing practice, providing a framework for making ethical decisions and fulfilling responsibilities to the public, colleagues and the profession.
AACN Certification Corporation’s mission of public protection supports a standard of excellence where certified nurses have a responsibility to read about, understand and act in a manner congruent with the ANA Code of Ethics for Nurses.

The AACN Synergy Model and Certification Exams
The AACN Synergy Model for Patient Care (Synergy Model) was developed to link clinical practice with patient outcomes. Integration of the Synergy Model into AACN Certification Corporation credentialing programs puts an emphasis on the patient and says to the world that patients come first.
Nurses make unique contributions to quality patient and family care, evidence-based practice and healthy work environments. AACN certification exams include a Clinical Judgment component and a Professional Caring and Ethical Practice component based on nurse characteristics of the Synergy Model, which involves Advocacy/Moral Agency, Caring Practices, Clinical Inquiry, Collaboration, Facilitation of Learning, Response to Diversity and Systems Thinking.
The Synergy Model — and its incorporation into AACN certification exams — is not for memorizing the various patient or nurse characteristics or their levels, but is intended to help with comprehension of the model. Exam questions cover application of the Synergy Model, not its terminology.
