A2LA is the only independent, 501(c)3, 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.
Established in 1978 as a non-profit, public service membership society, A2LA is dedicated to the formal recognition of competent testing and calibration laboratories, inspection bodies, proficiency testing providers, and reference material producers.
A2LA offers three main service lines to support recognition of competence in laboratory and laboratory-related industries.
Accreditation is synonymous with both quality and competence of an organization, through the use of international standard(s). A2LA is a third-party body that performs accreditations to various international standards, ensuring an unbiased and objective evaluation of your organization’s functions.

ISO/IEC 17065 for Product Certification Bodies ISO 17034 for Reference Material Producers
A2LA training programs are designed to help organizations achieve and maintain accreditation. Courses have been developed to:
Aid in establishing a management system that works with and enhances organizations as a whole.
Guide prospective applicants through the assessment and internal audit processes.
Aid in understanding how quality principles apply to various organizations.
Explain specific concepts, such as root cause analysis, measurement uncertainty, etc.
