Internal Audit Service (IAS) history


In celebration of its 20th anniversary, the Internal Audit Service (IAS) launched a history book.

Explore it

The Internal Audit Service (IAS) of the European Commission was created as a part of Administrative Reform in the late nineties.

It became an independent Service on the 4th of July 2001.

The Internal Audit Capabilities (IACs) and the Audit Progress Committee of the European Commission (APC) were created at the same time.

In 2003, the IAS was mandated to audit the EU agencies – today it has over 40 agencies and bodies in its portfolio.

The IAS was declared compliant with the Institute of Internal Auditors (IIA) Standards and Code of Ethics on the 4th of July 2008, following an external quality review.  Since then, further external quality assessments (EQA) have been completed with the IAS achieving the same satisfactory overall assessment of being generally compliant with the IIA Standards and Code of Ethics.
