Literature & commentary
IIA Nederland (Instituut van Internal Auditors)
IIA Nederland is the Dutch chapter of the Institute of Internal Auditors and the professional association for internal auditors: operational, financial, IT and compliance auditors at companies, public bodies, pension funds and institutions. Iia.nl carries the professional standards of the International Professional Practices Framework — both the earlier 2017 version and the revised 2024 standards — alongside news, Audit Magazine, research reports such as the annual Risk in Focus, podcasts and the quality assessment regime for audit functions.

What this source does not give you
The IIA's professional standards are a self-regulatory framework for the internal audit function, not a statutory norm: they bind the auditor who commits to them and the organisation that has anchored them in its audit charter, not everyone. Part of the offering — training, certifications, sections of the knowledge centre and the members' area — is also reserved for members or available only on payment, so not everything announced on the site is freely readable.
Frequently asked questions
- What is the difference between internal audit and an external audit?
- An external audit is a statutory engagement resulting in an opinion on the financial statements, performed by an independent, supervised audit firm. Internal audit is a function within the organisation that reports to the board and audit committee and addresses the operation of governance, risk management and internal control across the board — not only financially. The IIA's standards concern that second function; they contain no auditing standard for the financial statements.
- Which version of the professional standards applies?
- IIA Nederland publishes both the 2017 professional standards and the revised 2024 standards, and that is not an oversight: the revision was structurally significant and organisations did not all move across at the same time. Which version applies to an audit function is set out in its own audit charter and quality documentation, not on the institute's website. So state explicitly in any report or assessment which version was used.
- What is Risk in Focus and how much weight does it carry?
- Risk in Focus is an annual research report in which European IIA institutes map which risks internal auditors rate highest for the year ahead, based on surveys and interviews among heads of internal audit. It is a snapshot of what the profession itself considers important — useful for setting the agenda of an audit plan or a risk discussion in the audit committee. It is not an independent risk measurement and not standard-setting; the report says what auditors expect, not what is factually the case.
- Is the professional content on iia.nl freely accessible?
- Partly. News items, announcements and part of the knowledge centre are open, and the site has a separate entry point for the professional standards. Alongside that there is a member login, paid training through the academy and certification tracks such as CIA, CRMA and Internal Audit Practitioner. So when citing, do not assume the reader can open the underlying document without a membership.
