"Reliable Results Through Recognized Accreditation"


About Us


Public and private sector organizations founded the not-for-profit National Cooperation for Laboratory Accreditation (NACLA) in 1998 to provide coordination and focus for laboratory accreditation programs in the US. NACLA’s primary mission is to evaluate US laboratory accreditation bodies (ABs) and to grant recognition to those ABs in compliance with NACLA procedures and the relevant international standards for competent ABs, including ISO 17025, ISO 17020 and ANSI/NCSL Z540.3. (NACLA does not itself accredit laboratories performing scientific testing.) NACLA also provides educational and training opportunities to persons interested in improving scientific testing using ISO 17025 and other international standards.

NACLA is a stakeholder organization. Accordingly, its leadership body, the Board of Directors is composed of balanced representation from our four key stakeholder groups: Industry, Government, Laboratories performing scientific testing and Accreditation Bodies interested in instilling competence in scientific testing. Past and present members of the Board include representatives of Caterpillar, Ford, GE, GM, Lucent Technologies, DOD, DOE, FDA, FHWA, NIST, USDA, US Navy, major laboratory associations and major accreditation bodies.  In addition, NACLA has a Standards Committee and Acceptance Panel as well as a long list of NACLA specifiers requiring NACLA recognition of accreditation bodies.

Membership in NACLA is open to organizations in the four stakeholder groups noted above and to any other organization that wishes to support NACLA goals and objectives to improve scientific testing, including compliance with ISO 17025. To join, complete the NACLA Membership Application.  To view past activities, visit our Archives page.

NACLA’s work is accomplished by a cadre of volunteers from its member organizations.  To view the NACLA meeting schedule, click here.  NACLA's Executive Officer is
