The activities that are specifically required by ISO 17021-1 as part of third-party (Certification Body) surveillance audit processes are:

•Option A: Audit use of certification marks on marketing materials. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to audit the client’s use of marks and/or any other reference to certification, as applicable, to ensure conformity with the certification requirements.

•Option B: Review changes to the QMS since last visit. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review any changes affecting the client’s quality management system and its ability to continue to fulfil the requirements of the standard used for certification.

•Option C: Confirm effectiveness of internal audit and management review. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to confirm the continuing effectiveness of the client’s quality management system, including the effectiveness of the internal audit and management review processes.

•Option F: Review the status of previously raised findings and audit effectiveness of any outstanding findings. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review the status of findings and any corrective actions taken by the client in response to previous audits, and to verify the effectiveness of the implemented corrective actions.

•Option H: Verify legal compliance. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to verify the client’s compliance with applicable statutory and regulatory requirements related to the scope of certification.

•Option I: Handling of customer complaints since last visit. This option is correct because ISO 17021-1:2015 clause 9.6.2.2 requires the certification body to review the client’s handling of customer complaints related to the certified activities since the last audit.

The following options are not correct:

•Option D: Complete a full document review of the quality management system. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to complete a full document review of the quality management system during surveillance audits. A full document review is only required during the initial certification audit or when there are significant changes to the quality management system or the certification requirements.

•Option E: Failing to meet financial responsibilities. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to audit the client’s financial responsibilities during surveillance audits. The certification body may have contractual arrangements with the client regarding the payment of fees, but this is not part of the surveillance audit process.

•Option G: Review the calibration status of the instrumentation. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to review the calibration status of the instrumentation during surveillance audits. The certification body may audit the client’s monitoring and measuring resources as part of the quality management system requirements, but this is not a specific activity required by ISO 17021-1.

•Option J: Conduct a minimum number of annual surveillance audits during the certification period. This option is not correct because ISO 17021-1:2015 clause 9.6.2.2 does not require the certification body to conduct a minimum number of annual surveillance audits during the certification period. The certification body may determine the frequency and duration of surveillance audits based on the risk and performance of the client, but this is not a specific activity required by ISO 17021-1.
