In addition to the Yellow Book, which group's external audit standards can the GAO reference?

GAO and External Audit Standards:The Government Accountability Office (GAO) uses the Yellow Book as its primary standard. However, it may also reference external standards from recognized international and professional auditing organizations. INTOSAI is specifically mentioned in the Yellow Book as a source of additional standards for governmental audits.

Explanation of Answer Choices:

A. Public Company Accounting Oversight Board (PCAOB): This regulates audits of publicly traded companies, not government entities.

B. International Auditing and Assurance Standards Board (IAASB): This focuses on global private-sector audits, not specifically government-related.

C. International Organization of Supreme Audit Institutions (INTOSAI): Correct. INTOSAI sets audit standards for public-sector auditors worldwide and is relevant for the GAO.

D. AICPA: While the AICPA sets standards for U.S. auditors, INTOSAI is more relevant for international public-sector audits.
