The Institute of Internal Auditors (IIA) Global Internal Audit Standards (Standards) are officially in effect as of Jan. 9, 2025—introducing new domains, principles and standards that internal audit functions must follow. This article provides an overview of these changes and offers guidance on preparing for an external quality assessment (EQA) to help ensure compliance and enhance the effectiveness of your internal audit function. 

Overview of the new Standards 

The updated Standards are organized into five domains, encompassing 15 principles and 52 standards. These domains provide a structured approach to internal auditing, ensuring comprehensive coverage of all critical aspects.
