The Accreditation Association's mission is to promote its position as the preeminent leader in developing standards to advance and promote patient safety, quality, and value and measurement of performance for ambulatory health care through peer-based accreditation processes, education and research.

The Accreditation Association for Ambulatory Health Care, also known as AAAHC or the Accreditation Association, is a private, non-profit organization formed in 1979. It is the preeminent leader in developing standards to advance and promote patient safety, quality and value for ambulatory health care through peer-based accreditation processes, education and research. Accreditation is awarded to organizations that are found to be in compliance with the Accreditation Association standards.

The Accreditation Association currently accredits over 4,600 organizations in a wide variety of ambulatory health care settings, including ambulatory and surgery centers, managed care organizations, as well as Indian and student health centers, among others. With a single focus on the ambulatory care community, the Accreditation Association offers organizations a cost-effective, flexible and collaborative approach to accreditation.
