American Association for Laboratory Accreditation

About A2LA


The American Association for Laboratory Accreditation (A2LA) is a nonprofit, non-governmental, public service, membership society. We are the only independent (meaning that we are not governed by another, "parent" organization), non-profit, internationally-recognized accreditation body in the United States that offers a full range of comprehensive laboratory and laboratory-related accreditation services and training. Services are available to any type of organization, be it private or government. All of our accreditation programs are based on internationally-accepted criteria for competence. In addition to the accreditation of laboratories, A2LA offers programs for the accreditation of inspection bodies, proficiency testing providers, reference material producers and product certification bodies.

A2LA's Mission

Provide world-class accreditation and training services for testing and calibration laboratories, inspection bodies, proficiency testing providers, reference material producers and product certifiers. These and other future services should create stakeholder confidence in the quality, competence and integrity of all A2LA-accredited organizations and in their products and services.

A2LA's Vision

To be the premier provider of accreditations accepted everywhere and by everyone.
