IAI is accredited by the North American Accreditation Bureau (NAAB). NAAB is an ISO accreditation body located in North America formed primarily to accredit North American ISO registrars. However, they now provide ISO accreditation services to the international community.

GAF ensures that its accreditation body members, such as NAAB, only accredit bodies that are competent to do the work they undertake and are not subject to conflicts of interest as well as establishes mutual recognition arrangements between its accreditation body members.
