Standards and Guidance


The International Internal Audit Standards Board is pleased to announce that the draft of the proposed Global Internal Audit Standards(TM)  is available now through 30 May 2023 for public comment – a major milestone in the multiyear project to comprehensively review and update The IIA’s International Professional Practices Framework (IPPF) including the International Standards for the Professional Practice of Internal Auditing (Standards). 

After analyzing the responses and making necessary revisions, the Standards Board expects to release the new Global Internal Audit Standards(TM) officially before the end of 2023.

Revised Standards, Effective January 1, 2017

The International Internal Audit Standards Board (IIASB) released the revision to the Standards following consideration and approval by the International Professional Practice Framework Oversight Council (IPPFOC). 

The International Professional Practices Framework (IPPF) is the conceptual framework that organizes authoritative guidance promulgated by The Institute of Internal Auditors. A trustworthy, global, guidance-setting body, The IIA provides internal audit professionals worldwide with authoritative guidance organized in the IPPF as mandatory guidance and recommended guidance.

Mandatory Guidance


The Mission of Internal Audit describes internal audit's primary purpose and overarching goal. Achievement of the mission is supported by the entire IPPF, including the mandatory elements of the Definition, Core Prinicples for the Professional Practice of Internal Auditing, the Code of Ethics and Standards, as well as all recommended guidance.

The mandatory elements of the IPPF are:

Conformance with the principles set forth in mandatory guidance is required and essential for the professional practice of internal auditing. Mandatory guidance is developed following an established due diligence process, which includes a period of public exposure for stakeholder input.

Recommended Guidance

The recommended elements of the IPPF are:

Recommended guidance is endorsed by The IIA through a formal approval process. It describes practices for effective implementation of The IIA's Core Principles, Definition of Internal Auditing, Code of Ethics, and Standards.

Topics and Resources

The IIA guides the international profession of internal audit not only with Standards, but with numerous guidance resources to help internal auditors worldwide implement best practices in our ever-changing and growing field.
