A chief audit executive ensures that the internal audit activity provides annual training to management...

The nature of services provided by the internal audit activity, including training management on internal controls, is typically defined in the audit charter. The audit charter outlines the purpose, authority, and scope of the internal audit activity, including any advisory services it provides, such as training. It establishes the framework within which the internal audit team operates and serves as a formal document that specifies the arrangement between the internal audit function and the rest of the organization.
