It oversees the standard-setting activities of the International Auditing and Assurance Standards Board (IAASB) and the International Ethics Standards Board for Accountants (IESBA).

 

Why Was the PIOB Created?

Its creation was aimed at enhancing confidence in audit quality, ethical standards, and corporate reporting.

 

What is the PIOB’s Role?

The PIOB’s mission is to ensure that international standards are:

  • Responsive to the public interest
  • Developed through a transparent and robust due process
  • Informed by a broad range of stakeholder perspectives
  • Focused on enhancing confidence in corporate reporting and assurance services

Key Takeaway

The Public Interest Oversight Board (PIOB) is an independent international oversight body responsible for safeguarding the public interest in the development of global auditing and ethics standards. Rather than issuing standards itself, the PIOB oversees the standard-setting activities of the International Auditing and Assurance Standards Board (IAASB) and the International Ethics Standards Board for Accountants (IESBA) to help ensure that their processes are transparent, independent, and responsive to the needs of the public. Headquartered in Madrid, Spain, the PIOB publishes a range of materials, including annual and public reports, oversight publications, consultation responses, public interest assessments, governance updates, and transparency reports. Its work supports investors, regulators, standard-setters, professional accountancy organizations, audit firms, businesses, public interest entities, and other stakeholders who rely on high-quality international standards and credible corporate reporting. Through its oversight role, the PIOB helps strengthen confidence in the international audit and ethics standard-setting system and promotes standards that serve the broader public interest.
