Professional standards

Professional standards in Internal Audit

The International Professional Practices Framework (IPPF) is the conceptual framework that organizes authoritative guidance promulgated by The IIA. 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. The updated Framework was introduced in July 2015. Take a look at the video to learn more about it and access resources that explain how the Framework was established.

The International Professional Practices Framework (IPPF) is broken down to three components which are required and are essential for professional practice of internal auditing. The three components are

  • Definition of Internal Auditing
  • Code of Ethics
  • International Standards for the Professional Practice of Internal Auditing (Standards)

To support best practice IIA Global provide publications of best practice and advisories guidance documents known as:

  • Position Papers
  • Practice Advisories
  • Practice Guides.

These standards apply globally with over 185,000 internal auditors working within the framework.

More information on the framework, standards and guidance is available on the IIA Global website.

Conformance with the Standards is required and is essential for the professional practice of internal auditing. Questions about the Standards should be sent to

IIA Code of Ethics

The Code of Ethics is the authoritative guidance for the internal audit profession from the Global Institute of Internal Auditors. It's part of the International Professional Practices Framework.

The code states the principles and expectations that govern the behaviour of individuals and organisations in the conduct of internal auditing. It describes the minimum requirements for conduct, and behavioural expectations rather than specific activities.

The Code's principles are

1. Integrity

The integrity of internal auditors establishes trust and thus provides the basis for reliance on their judgement.

2. Objectivity

Internal auditors exhibit the highest level of professional objectivity in gathering, evaluating, and communicating information about the activity or process being examined. Internal auditors make a balanced assessment of all the relevant circumstances and are not unduly influenced by their own interests or by others in forming judgements.

3. Confidentiality

Internal auditors respect the value and ownership of information they receive and do not disclose information without appropriate authority unless there is a legal or professional obligation to do so.

4. Competency

Internal auditors apply the knowledge, skills and experience needed in the performance of internal auditing services.
