The INTOSAI Framework
The International Organization of Supreme Audit Institutions (INTOSAI) acts as the global umbrella body for the public sector audit community. INTOSAI develops and maintains the IFPP (INTOSAI Framework of Professional Pronouncements), which contains the core International Standards of Supreme Audit Institutions (ISSAIs). These standards adapt commercial auditing concepts (such as the International Standards on Auditing [ISAs] issued by the IAASB) to fit the complex legal realities of government administration.
Structural Architecture of the ISSAI Core Framework
The ISSAI framework is organized into clear, hierarchal tracks to guide public auditors systematically:
  • INTOSAI Principles (GUID 10-99): High-level founding principles defining the constitutional prerequisites of public auditing, including the Lima Declaration and the Mexico Declaration on SAI Independence. [1]
  • Core Principles (ISSAI 100): Establishes the foundational principles for public sector auditing as a whole. It outlines common requirements for professional judgment, quality control, ethics, and documentation.
  • Organizational Standards (ISSAI 140): Dictates the internal quality control systems that a Supreme Audit Institution must build to ensure its own work remains unbiased, robust, and accurate.
  • Auditing Standards (ISSAI 200, 300, 400): The technical, execution-level standards governing the three primary types of public audits: Financial Auditing (ISSAI 200), Performance Auditing (ISSAI 300), and Compliance Auditing (ISSAI 400).

Professional Ethics for Public Sector Auditors: ISSAI 130
Public auditors hold access to highly sensitive state data, tax records, and classified national security budgets. ISSAI 130 (Code of Ethics) mandates strict adherence to five core ethical values:
  1. Integrity: Acting honestly, in good faith, and strictly in the public interest.
  2. Independence and Objectivity: Remaining free from political influence, personal biases, or structural conflicts of interest involving audited ministries.
  3. Competence: Maintaining the technical skills and accounting knowledge required to analyze complex public ledgers and ERP systems.
  4. Professional Behavior: Complying with all applicable laws and avoiding any actions that could bring discredit to the audit institution.
  5. Confidentiality and Transparency: Protecting state secrets and proprietary entity information, while ensuring that the final public audit report is clear and accessible to the public.
