Founded in 1931, the American Association of Nurse Anesthetists (AANA) is the professional association representing more than 28,000 Certified Registered Nurse Anesthetists (CRNAs) nationwide. The AANA promulgates education, and practice standards and guidelines, and affords consultation to both private and governmental entities regarding nurse anesthetists and their practice. The AANA Foundation supports the profession through award of education and research grants to students, faculty and practicing CRNAs.

The AANA developed and implemented a certification program in 1945 and instituted mandatory recertification in 1978. It established a mechanism for accreditation of nurse anesthesia educational programs in 1952, which has been recognized by the U.S. Department of Education since 1955. In 1975, the AANA was a leader among professional organizations in the United States by forming autonomous multidisciplinary councils with public representation for performing the profession's certification, accreditation, and public interest functions. Today, the CRNA credential is well recognized as an indicator of quality and competence.

Promote excellence in nursing through professional development, shape health policy, and support the professional nurse in the workplace environment.
