The International Organization of Supreme Audit Institutions (INTOSAI) is an intergovernmental organization whose members are supreme audit institutions. Nearly every supreme audit institution in the world is a member of INTOSAI. Depending on the type of system used in their home country, the members of INTOSAI may be variously titled the Chief Financial Controller, the Office of the Comptroller General, the Office of the Auditor General, the Court of Accounts, or the Board of Audit.
INTOSAI was founded in 1953[3] in Havana, Cuba.[4] Thirty-four audit organizations formed the group originally and as of 2010 the current membership includes 193 institutions (188 national institutions, the European Court of Auditors and 4 associated members).[3]
The members of INTOSAI are the primary external auditors of the United Nations.[4] The UN's General Assembly appoints the UN Board of Auditors (3 members appointed for 6 years) among the INTOSAI member representatives.[5]
International Standards of Supreme Audit Institutions
The International Standards of Supreme Audit Institutions (ISSAI) are a benchmark for auditingpublic entities (External Audit Standards for public entities).
The "INTOSAI Auditing Standards" had been approved by the INCOSAI in 1998 and updated in 2001. In its strategic plan 2005–2010, the INTOSAI decided to "provide an up-to-date framework of professional standards", so the INTOSAI Professional Standards Committee decided to merge the existing and new INTOSAI standards and guidelines into a framework.
The framework comprises all documents endorsed by INCOSAI with the purpose of guiding the professional standards used by SAIs
The list of ISSAIs is in the table below:
Auditing Standards (ISSAI-numbers of 3 digits) stipulate general principles and postulates for carrying out the audit work;
Implementation Guidelines (ISSAI-numbers of 4 digits) give more detailed guidance, practical assistance to SAIs in implementing the Standards in their individual constituents.
Financial audit focuses on determining whether an entity’s financial information is presented in accordance with the applicable financial reporting and regulatory framework. This is accomplished by obtaining sufficient and appropriate audit evidence to enable the auditor to express an opinion as to whether the financial information is free from material misstatement due to fraud or error.
Performance Audit
Performance audit focuses on whether interventions, programmes and institutions are performing in accordance with the principles of economy, efficiency and effectiveness and whether there is room for improvement. Performance is examined against suitable criteria, and the causes of deviations from those criteria or other problems are analysed. The aim is to answer key audit questions and to provide recommendations for improvement.
Compliance Audit
Compliance audit focuses on whether a particular subject matter is in compliance with authorities identified as criteria. Compliance auditing is performed by assessing whether activities, financial transactions and information are, in all material respects, in compliance with the authorities which govern the audited entity. These authorities may include rules, laws and regulations, budgetary resolutions, policy, established codes, agreed terms or the general principles governing sound public sector financial management and the conduct of public officials.

Guidelines for Internal Control Standards for the Public Sector (1992 - The current text is the 2004 revision by the INTOSAI Internal Control Standards Committee, approved by the XVIIIth INCOSAI of October 2004. It has been subsequently integrated in the INTOSAI standards/guidances as "INTOSAI GOV 9100"). It relies upon the COSO's integrated framework for internal control (as stated in the preface), and uses the COSO's definition of Internal Control and IIA's definition of Internal Audit.

INTOSAI Guidance for Good governance: INTOSAI GOVs 9100–9230
The guidance "INTOSAI GOV 9100" states:
(page 46) "The Supreme Audit Institution also has a vested interest in ensuring that strong internal audit units exist where needed. Those audit units constitute an important element of internal control by providing a continuous means for improving an organisation's operations. In some countries, however, the internal audit units may lack independence, be weak, or be non-existent. In those cases, the SAI should, whenever possible, offer assistance and guidance to establish and develop those capacities and to ensure the independence of the internal auditor's activities."
"The creation of an internal audit unit as part of the internal control system is a strong signal by management that internal control is important. ... For an internal audit function to be effective, it is essential that the internal audit staff be independent from management, work in an unbiased, correct and honest way and that they report directly to the highest level of authority within the organisation. ... "For professional guidance, internal auditors should use the Professional Practices Framework (PPF) of the Institute of Internal Auditors (IIA) (...) Additionally, internal auditors should follow the INTOSAI Code of Ethics".
