Which organization accredits those that register companies to ISO 9000 series standards?

The Registrar Accreditation Board (U.S.) is the organization responsible for accrediting registrars that issue certifications to companies for compliance with the ISO 9000 series of standards. This accreditation ensures that the registrars meet specific criteria and maintain high standards in their auditing and certification processes, providing assurance that organizations conform to quality management principles set forth in ISO 9000.

This organization plays a crucial role in the certification chain, as it evaluates and monitors the registrars to ensure they are competent and consistent in assessing companies against the ISO standards. Without such a regulating body, the integrity of the certification process could be compromised.

The other options are related to various aspects of standards development and implementation but do not directly accredit registrars. The International Standards Organization develops the standards but does not accredit registrars. The American National Standards Institute oversees the development of American standards but is not specific to the accreditation of ISO registrars. The Quality Management Association does not hold a recognized role in the accreditation process for ISO 9000 registrars.
