IAS Accreditation

IAS is a nonprofit, public-benefit corporation that has been providing accreditation services since 1975.

Also maintains signatory status in a number of global multilateral recognition arrangements under Asia Pacific Accreditation Cooperation (APAC), International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC). the American Accreditation is a member of the ICC Family of Solutions.

International Credentials

As one of the leading accreditation bodies in the United States, IAS is a signatory to the three primary international organizations that form a unified system for evaluating and recognizing competent accreditation bodies worldwide. These organizations are identified as “cooperation’s” because they have agreed to cooperate with one another by adhering to a common set of accreditation criteria and to undergo periodic onsite evaluation to determine ongoing compliance with ISO/IEC Standard 17011, General Requirements for accreditation bodies accrediting conformity assessment bodies (CABs). Being a “signatory” means that an accreditation body has been evaluated onsite at its offices, a sampling of the assessments of its accredited entities have been witnessed by peer experts, and that it has been found to comply with international requirements.

These organizations agree to recognize the equivalence of accreditations granted by other signatory member accreditation bodies through a series of Mutual (or Multilateral) Recognition Arrangements (MRAs/MLAs). Once an accreditation body becomes a signatory it is obligated to recognize the certificates or reports issued by conformity assessment bodies accredited by all other signatories within a specified scope. The following organizations below make up the unified system for recognition of competent accreditation bodies (ABs).



MRA – ABs involved in the accreditation of testing laboratories, calibration laboratories, inspection bodies, proficiency testing providers and reference material producers. IAS is a MRA signatory for testing, calibration, and inspection..



MLA – ABs involved in the accreditation of management systems, certification of persons, and certification of product, process and services. IAS is a MLA signatory for Certification of Persons (IPC), Product Certification (Global G.A.P.), and Management System Certification (QMS, EMS, OHSMS, ISMS, EnMS, FSMS and MDQMS).



MRA – The Asia Pacific Accreditation Cooperation (APAC) was established on 1 January 2019 by the amalgamation of two former regional accreditation cooperation – the Asia Pacific Laboratory Accreditation Cooperation (APLAC) and the Pacific Accreditation Cooperation (PAC). The MRA facilitates the acceptance of conformity assessment results (e.g. test reports, test certificates, inspection reports, and certification) across the region and with other regions around the world. IAS is a MRA signatory for Testing, Calibration, Inspection, Certification of Persons, Product Certification, and Management System Certification.



Full Member – The InterAmerican Accreditation Cooperation (IAAC) is a regional association of accreditation bodies and other organizations interested in conformity assessment in the Americas. The IAAC was created in 1996, in Montevideo, Uruguay, and was incorporated in 2001 as a civil association according to Mexican law. IAAC is a not-for-profit body that functions based on cooperation by its members and interested parties. IAAC’s basic documents are the Memorandum of Understanding and Bylaws. IAS was accepted as an IAAC full member by the General Assembly on May 26, 2021.

The Accreditation Process

IAS accredits organizations by verifying their technical competence and assessing their quality management systems based on recognized industry standards.

The accreditation process begins with the customer’s submittal of an application, applicable fees, and documentation cited in the applicable IAS accreditation criteria.

An IAS accreditation officer partners with each customer throughout the accreditation process, beginning with a review of the submitted data and the requested scope of accreditation.

Once the data has been reviewed and determined to comply with the applicable criteria, IAS matches an assessment team, comprising quality system, technical, and subject matter experts, to the requested scope of accreditation. The team conducts an on-site assessment and develops an assessment report.

After satisfying IAS accreditation requirements and demonstrating technical competence, the customer receives an accreditation certificate.

Who Does IAS Accredit?

IAS accredits a wide range of companies and organizations involved in conformity assessment activities such as testing, inspection, certification, fabrication, code compliance and enforcement.

A pioneer in the accreditation profession, IAS actively develops new accreditation programs for organizations seeking to demonstrate the highest level of competence and service in their respective industries.

The IAS accreditation process provides objective evidence that an organization operates at a high level of organizational, legal and technical standards.

IAS bases its programs on internationally recognized standards in order to ensure worldwide acceptance of your accreditation.

The accreditation criteria have been developed by IAS to provide all interested parties with guidelines for implementing performance features of the applicable standards referenced in the accreditation criteria. The criteria were developed following public hearings conducted by the IAS Accreditation Committee.
