I did the auditor leader cert many years ago and at this time I would be interested in renewing this cert. Do I still have to take the workshops and the exam , or , is there another option for me as I'm interested in just renewing a cert I already took once?
To renew your certification you have two options:
1 - You should consult your certification issuer, or other accredited training provider, to verify if they provide an update course related to your lead auditor certification. Normally these courses are available after a new version of a standard is released. Such courses presents to auditors what has changed in the release of a new version of a standard, and can be used to renew a certificate.
2 - You can take a full course and retake the exam. Here you can have access to the accredited Lead Auditor course provided by Advisera: https://advisera.com/training/iso-27001-lead-auditor-course/
It is important to no te that for purposes to become an auditor for a certification body you have to renew your certificate before the three years period validity of the lead auditor certificate expires.
