The International Auditing and Assurance Standards Board (IAASB) is an independent standard-setting body that serves the public interest by setting high-quality international standards for auditing, quality control, review, other assurance, and related services, and by facilitating the convergence of international and national standards. In doing so, the IAASB enhances the quality and uniformity of practice throughout the world and strengthens public confidence in the global auditing and assurance profession.

The IAASB’s Strategy for 2015-2019 and the IAASB Work Plan for 2015-2016 set the direction and priorities for its activities. The IAASB’s efforts are focused on development, adoption and implementation of international standards addressing audit, quality control, review, other assurance, and related services engagements.

The IAASB’s medium-term strategy addresses the following three main themes in the public interest:

  • Supporting global financial stability;
  • Enhancing the role, relevance and quality of assurance and related services in an evolving world; and
  • Facilitating adoption and implementation of the standards.

The IAASB follows a rigorous due process in developing its pronouncements. Input is obtained from a wide range of stakeholders including the IAASB’s Consultative Advisory Group national auditing standard setters, IFAC member bodies and their members, regulatory and oversight bodies, firms, governmental agencies, investors, preparers, and the general public. Exposure Drafts of proposed pronouncements are posted on the website and comments are invited; final pronouncements are accompanied by a Basis for Conclusionswith respect to comments received. The Public Interest Oversight Board (PIOB) oversees the work of the IAASB and its CAG to ensure that the activities of the IAASB follow due process and are responsive to the public interest.

The IAASB is dedicated to operating as transparently as possible. IAASB meetings are open to the public and meeting agendas, agenda papers, and meeting highlights are posted on the website. In addition, the website includes project histories, audio recordings of the IAASB meetings, IAASB Exposure Drafts and all comments made on those drafts by stakeholders.


The International Auditing and Assurance Standards Board (IAASB) was founded in March 1978. It was previously known as the International Auditing Practices Committee (IAPC).

The IAPC’s initial work focused on three areas: object and scope of audits of financial statements, engagement letters, and general auditing guidelines. In 1991, the IAPC’s guidelines were recodified as International Standards on Auditing (ISAs).

In 2001, a comprehensive review of the IAPC was undertaken, and in 2002, the IAPC was reconstituted as the International Auditing and Assurance Standards Board (IAASB). In 2003, IFAC approved a series of reforms designed, among other things, to further strengthen its standard-setting processes, including those of the IAASB, so that they are responsive to the public interest.

In 2004, the IAASB began the Clarity Project, a comprehensive program to enhance the clarity of its ISAs. This program involved the application of new conventions to all ISAs, either as part of a substantive revision or through a limited redrafting to reflect the new conventions and matters of clarity generally.
