After successful completion of the ISO 9001 lead auditor training , you can be a qualified auditor for third-party auditing.

You can be a part of the IRCA by registering yourself there.
As a lead auditor, you are qualified to issue certificates to internal auditors.
Moreover, you don’t have to keep renewing your certificate as an auditor by taking up auditor training on a regular basis. You will be required to do it only when the standards are revised.

Thus, IAS helps you get the best ISO training in India easily and perform better in your professional role.
