This activity is permitted, provided that the certification body minimizes disturbance to the certification process, making option A the correct answer. ISO/IEC 17021-1, which governs certification bodies providing management system certification, explicitly allows certification bodies to evaluate the competence and performance of their auditors. This includes on-site witnessing of auditors during actual certification audits.
The purpose of such evaluations is to ensure auditor competence, consistency, and adherence to certification procedures. ISO/IEC 17021-1 requires certification bodies to maintain confidence in their certification activities by monitoring and evaluating auditors in real audit situations. Conducting these evaluations on-site is a common and accepted practice, especially for initial competence assessments or periodic performance reviews.
However, the certification body must ensure that the evaluation does not interfere with the audit objectives or disrupt the client’s operations. Option B is incorrect because there is no requirement or justification for suspending the client’s business activities. Certification audits are designed to be conducted alongside normal operations whenever possible. Option C is incorrect because while remote evaluations may be used in some circumstances, the standard does not prohibit on-site evaluations.
Therefore, an on-site evaluation of an auditor during a certification audit is permitted, provided that it is carefully managed and does not disrupt the certification process or the auditee’s normal operations.
