Revision of the fundamental auditing principles

The revision of the fundamental auditing principles was completed in 2013 with the endorsement of four new ISSAIs on level 3 of the ISSAI Framework (ISSAI 100, 200, 300 and 400) at INCOSAI in Beijing, China.   

Project summary

The ISSAI Harmonisation Project was launched by the XX INCOSAI in 2010 in order to provide a common conceptual basis for public-sector auditing for all ISSAIs and all INTOSAI members. This is achieved by revising the fundamental auditing principles (ISSAIs 100-999) at level 3 of the ISSAI framework.

The project has resulted in 4 new ISSAIs which will take effect from the XXI INCOSAI in Bejing in October 2013:

ISSAI 100 - Fundamental Principles of Public-Sector Auditing

ISSAI 200 - Fundamental Principles of Financial Auditing

ISSAI 300 - Fundmamental Principles of Performance Auditing

ISSAI 400 - Fundamental Principles of Compliance Auditing

The fundamental auditing principles contain the key principles for public sector auditing and will provide a basis for all types of public sector audit engagements whatever their form or context. The principles also define how the ISSAIs can be used and refered to as an international set of auditing standards.
