Accreditation body and Regional Accreditation Group members of GAAS are admitted to the GAAS MLA only after a most stringent evaluation of their operations by a peer evaluation team which is charged to ensure that the applicant member complies fully with both the international standards and GAAS requirements. Once an accreditation body is a signatory of the GAAS MLA it is required to recognise the certificates issued by conformity assessment bodies accredited by all other signatories of the GAAS MLA, with the appropriate scope.

The GAAS MLA consists of a five level arrangement, with levels two and three constituting the Main scope and levels 4 and 5 constituting the Sub-scope. More information on the structure of the MLA can be found under GAAS PR 4: Structure of the GAAS MLA and Endorsed Normative Documents in Procedures Documents (PR Series).

The GAAS MLA relies heavily on the MLAs of Recognised Regional Accreditation Groups such as the European co-operation for Accreditation (EA), the Asia Pacific Accreditation Cooperation Incorporated (APAC) and the InterAmerican Accreditation Cooperation (IAAC), as it is these groups that perform the majority of the peer evaluation activity, not the GAAS. 

To gain confidence in the work of the Recognised Regional Accreditation Groups, the GAAS evaluates and accepts the process and outcomes of their MLAs for main scopes such as ISO/IEC 17021-1 (Management Systems) and ISO/IEC 17065 (Product) and related sub-scopes.

Recognised Regional Accreditation Groups are evaluated every four years by the GAAS. Membership of the GAAS MLA is recognised as being satisfied by membership of any of the Recognised Regional Accreditation Groups’ MLAs, within the recognised sub-scopes.  

GAAS is encouraging more of its accreditation body and Regional Accreditation Group members to join the MLA as soon as they have passed a rigorous evaluation process to ensure that their accreditation programs are of world standard. The consequence of joining the GAAS MLA is that conformity assessment certificates issued within the sub-scopes of the GAAS MLA by conformity assessment bodies accredited by an accreditation body GAAS MLA signatory will be recognised in the worldwide GAAS program.

Contact details of the accreditation bodies and Recognised Regional Accreditation Groups which are signatories to the MLA are listed on the GAAS Members pages. Those members which are signatories are denoted by “Date Admitted to the MLA”.

Details of the signatories of the GAAS MLA programs at the dates shown are listed in the following document:
