The audit of UNFPA activities is carried out by UNFPA's external and internal auditors:
- External audit: fulfilled by the United Nations Board of Auditors (BoA); and
- Internal audit: assigned to the Division for Oversight Services (DOS), in particular the Internal Audit Branch.
The UN Board of Auditors was established by the General Assembly in 1946 to carry out the external audit of the accounts of the United Nations organization and its funds and programmes. The UN Board of Auditors’ report on the UNFPA financial statements is a public document that is presented to the General Assembly through the Fifth Committee and after review and advice by the Advisory Committee on Administrative and Budgetary Questions (ACABQ). The UN Board of Auditors’ report on UNFPA financial statements is also presented to the UNFPA Executive Board.
As defined by the Institute of Internal Auditors (IIA) "Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes."
Internal audit activities are carried out by the Division for Oversight Services (DOS), through its Internal Audit Branch. In 2010, DOS was subject to an external quality assessment conducted by the IIA, where DOS "generally conforms to the Standards and Definition of Internal Audit".
