In order to become a GWO approved certification body, the certification body must meet the requirements outlined in the Requirements for Certification section 5. As of April 1, 2019, it is a mandatory requirement for the certification body to document conformity with the requirements in this document for the certification body itself, and the audit team members specifically, prior to performing an audit. Pending this, the certification body will be listed on the GWO website as an approved certification body.
