United Nations Audit Office

The United Nations Office of Internal Oversight Services (OIOS) acts like an internal auditor, checking that the UN’s programs and funds are used effectively, efficiently, and according to rules. It reviews financial management, programs, and operations to identify issues and recommend improvements. Its goal is to ensure transparency, accountability, and proper use of resources within the UN, helping member countries trust that their contributions are managed responsibly. Essentially, OIOS helps safeguard the integrity of the UN’s work by providing independent assessments and preventing misuse or errors.
