Entity-level controls are the most effective type of controls for mitigating the largest risks facing an organization. These controls operate across an organization, providing a top-down approach to risk management that affects the entire entity's operations and culture. Such controls include governance frameworks, leadership and management philosophy, and organizational structure.References: COSO Internal Control Framework

According to IIA guidance, the chief audit executive is required to report the results of the quality assurance and improvement program, including external assessments, at least annually. This ensures that the board and senior management are kept informed about the internal audit activity's conformance with the Standards and other aspects of audit quality.References: IIA's International Standards for the Professional Practice of Internal Auditing on Quality Assurance and Improvement.

According to IIA guidance on mentoring programs, there is no requirement for a mentor to be in a higher organizational position than the mentee. The focus is on the value of diverse mentoring relationships, which can include auditors at the same level having different mentors or some auditors having no mentor at all. This approach allows for flexibility in the mentoring process and ensures that professional development needs are met effectively without strict hierarchical constraints.References: The Institute of Internal Auditors (IIA) - Guidance on mentoring programs
