There is a requirement in all ISO Management Standards that auditors should be selected and audits should be conducted to “ensure objectivity and the impartiality of the audit process”.
This is interpreted as meaning that you should audit your own area of responsibility and that businesses should have at least 2 internal auditors.
Whilst there is nothing very clever about the internal auditing process, it is important that those undertaking your internal auditing know what they are doing and evidence of their training and competence will be checked by the external auditor.
To be effectively trained as an internal auditor takes about 6 hours in three two hour sessions with the final session concentrating on using your system so that the auditors are “audit ready”.
It is possible to train up to four auditors at a time.
An outline of the training is on the following page:
