- From 6th September 2021 all Certification Bodies and Auditors must register on GWO's WINDA platform and hold a valid WINDA ID.
- The qualifications of team members shall follow the general rules for accreditation regarding auditor qualifications and relevant sector codes.
- An ISO 9001:2015 or similar lead auditor can cover the audit of the Quality Management System of a training provider.
- An ISO45001:2018 or similar lead auditor must cover the audit of a training session on-site.
- Auditors who wish to perform GWO audits must have successfully completed the GWO Auditor Qualification Training.
- The Auditor Qualification Training is valid for 3 years before needing to be refreshed and under the condition that the auditor remains active by performing at least 2 audits under the GWO scheme every year.
- If the auditor does not conduct at least 2 audits within a 12-month interval, the auditor must complete the Auditor Qualification Training again.
- Until April 2021, as an alternative to Auditor Qualification Training, the auditor may qualify by having completed and/or witnessed the GWO module(s) equivalent to the training standard module(s) the audit is performed against. If there is no GWO training provider offering this module within reasonable travel distance (e.g. in the same country), then the requirement may be met by the ISO 45001:2018 auditor having completed and/or witnessed a similar training module aimed at the wind industry. From April 1, 2021, the requirement to having witnessed or participated in the specific training module no longer applies and is replaced by 6.2.4.
- Certificates provided to GWO from auditors that have not documented conformance and passed the Auditor Qualification Training will not be accepted.
- The certification body shall keep records of the audit team, and of the audit they have participated in, for at least the validity period of the certification plus three months.
