PECB ISO-9001-Lead-Auditor Exam - Topic 1 Question 42 Discussion

Posted by Erin on May 15, 2026 at 07:44 AM

Who would be defined as a witness during a witness audit?

Choose two of the following options:

Suggested Answer: B, D

Comprehensive and Detailed = According to the web search results from my internal tool, a witness audit is a technique used during an accreditation audit, where the accreditation body observes the performance and competence of the certification body auditors in conducting an audit12. A witness audit can also be used by a certification body to monitor and evaluate its own auditors3. During a witness audit, the following roles can be defined:

*An auditor: This is the person who is being witnessed by the accreditation body or the certification body. The auditor is responsible for conducting the audit according to the audit plan, criteria, and standards, and for providing audit evidence and findings123.

*An assessor for the accreditation body: This is the person who witnesses the auditor on behalf of the accreditation body. The assessor is responsible for evaluating the auditor's performance and competence, and for providing feedback and recommendations to the accreditation body123.

The other options are not defined as witnesses during a witness audit, according to the web search results from my internal tool. They are:

*Someone with a qualification from the certification body: This is not a specific role in a witness audit, as anyone who is involved in the audit process should have a qualification from the certification body. Moreover, having a qualification does not necessarily mean that the person is a witness or an auditor4.

*An existing member of the audit team: This is not a specific role in a witness audit, as the audit team consists of the auditors who are conducting the audit, not the ones who are witnessing it. The witness audit is a separate activity from the audit itself, and the witness should not interfere with the audit process or influence the audit outcome123.

Therefore, the correct answer is B and D.

I feel like the certification body’s qualification might not be enough to define someone as a witness. I’m leaning towards B and D, but I need to double-check my notes.
JU

I’m really unsure about this one. I thought a witness had to be independent, so maybe A and D? But I could be wrong.

I remember practicing a question like this, and I think it was about the role of the auditor. But I'm not sure if an existing member of the audit team counts as a witness.

I think a witness in an audit is someone who observes the process, so maybe it could be the auditor or the assessor from the accreditation body?
