Performance audit

Performance audit refers to an independent examination of a program, function, operation or the management systems and procedures of a governmental or non-profit entity to assess whether the entity is achieving economy, efficiency and effectiveness in the employment of available resources. The examination is objective and systematic, generally using structured and professionally adopted methodologies.

In most countries, performance audits of governmental activities are carried out by the external audit bodies at federal or state level. Many of these audit bodies have established guides for conducting performance audits which explain how performance audits are planned, conducted and its results reported.

INTOSAI, the international association of Supreme Audit Institutions, has published generally accepted principles of performance auditing in its implementation guidelines. In the United States, the standard for government performance audits is the Generally Accepted Government Auditing Standards (GAGAS), often referred to as the "yellow book", maintained by the federal Government Accountability Office (GAO). Similarly, the European Court of Auditors (ECA) has developed a "performance audit manual" for its audits of the sound financial management of the European Commission and the programmes funded through the EU budget.
