Certification bodies listed on this site are permitted to certify a GWO training facility. If you choose a certification body that is not listed below, your certification will be rejected.
From 1 April 2019, all certification bodies wishing to certify against GWO standards and requirements must, prior to performing an audit, document their compliance with the GWO Requirements for Certification Bodies.
If you prefer to use another certification body than those listed, please ask them to provide this documentation to GWO. Alternatively, you can encourage your certification body to complete GWO Auditor Qualification Training.
