The role of internal auditors in assessing how an organization promotes ethics and values internally and with external business partners involves reviewing the organization's objectives, programs, and activities related to these areas. This approach aligns with the standard practice of internal auditing, which aims to ensure that an organization's processes and policies support its ethical standards and values.References: Institute of Internal Auditors (IIA) Standards and Guidelines.

According to the IIA's Standards, if it has been more than five years since the last external assessment was conducted, the Internal audit activity must cease indicating that it operates in conformance with the Standards.
Regular external assessments are required at least once every five years to validate that an internal audit activity continues to operate in conformance with the Standards.References: Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)
