For the internal audit activity to achieve conformance with the Standards, it is crucial that the internal audit charter has been approved by the board within the past year. Regular approval and review of the charter by the board ensure that it remains relevant and aligned with the organization’s objectives and governance frameworks. This approval process is part of maintaining the necessary authority and scope as prescribed by The IIA standards.
