About us

GAAS has been in business since 1989, having recognized early on the need for accreditation bodies to oversee the work of third-party certification bodies and thus provide credibility and confidence for those who rely on certification. GAAS was the first management systems accreditation body in the United States.About us

GAAS issued its first accreditation for ISO 9001 in 1991 and for ISO 14001 in 1997. GAAS was the first to offer accreditation for the AS9000 aerospace standards and TL 9000 for telecommunications, and remains the only North American accreditation body offering such accreditation.

GAAS’s maturity as a management system accreditation body speaks for itself! Our reputation for customer-focused service has led to our accreditation symbol being recognized and sought after worldwide and by numerous industries. This is due in no small part to the competence, knowledge, and experience of our employees, contract assessors, technical experts, and the volunteers who serve on our Management Systems Accreditation Council. It is also a reflection of our organizational culture.

GAAS was one of the original organizers of the International Accreditation Forum (IAF), established to promote cooperation among accreditation bodies. We were among the first to sign the IAF multi-lateral recognition arrangements (MLAs) for quality and environmental management systems.

Just as we have from the start, GAAS focuses on customer needs while ensuring conformance with requirements. We are committed to working internationally to promote sound, rigorous, and harmonious accreditation processes.  

Accreditation Process

Accreditation is based on conformance to ISO/IEC 17021-1. GAAS accredits certification bodies (CBs) that demonstrate competence to audit and certify organizations conforming with management system standards.* Accreditation by GAAS ensures the impartiality and competence of the CB and fosters confidence and acceptance of the CB's certifications by public and private sector end users.
