Internal Oversight Service

IOS provides an independent consolidated oversight mechanism that covers internal audit, evaluation, investigation and other management support to strengthen the functioning of the Organization.

Guided by its Charter, IOS is mandated with providing assurance that programmes are delivered efficiently and effectively, that strategic management information is reliable and timely, and that continuous improvements are fostered in methods and procedures to enhance the quality and impact of UNESCO’s operations.

IOS produces annual work plans using a risk-based approach and reports regularly to Governing Bodies through IOS Annual Reports on progress in delivering its oversight activities.

IOS is part of a broader oversight mechanism for UNESCO that includes the UNESCO Oversight Advisory Committee (OAC), the External Auditors and the Joint Inspection Unit (JIU) .
