Auditor qualifications

Answer:
Persons are not ISO 14001 certifiable. So, your question can have two
meanings:
1. If a person helped an organization to get its certification, can it be
a qualified auditor?
2. If a person passed an exam about ISO 14001, can it be a qualified
auditor?

A qualified auditor is a person with knowledge both about the management
standard used as a reference, and about good auditing practices. Whatever
the meanings mentioned above, 1 or 2, there is no guarantee that the person
knows about good auditing practices.

auditors:
