Usage of Internal Auditing Standards by companies in the United States and select European countries

Purpose - The purpose of this paper is to investigate differences in the degree of usage and compliance with the Institute of Internal Auditors (IIA) International Standards for the Professional Practices of Internal Auditing (Standards) by organizations' internal audit activities (IAA) located in the USA and a sample of European countries which have affiliates with the IIA. This paper shows the differences among Belgium, Italy, The Netherlands, the UK and Ireland, and the USA with respect to the level of use of the Standards and compliance with the Standards by respondents' IAAs. Design/methodology/approach - Survey results from questionnaires sent to IIA members in September 2006 about various topics relating to internal auditing are summarized in the Common Body of Knowledge 2006 database. These results are compared among Belgium, Italy, The Netherlands, the UK and Ireland, and the USA. Findings - This paper shows the differences among Belgium, Italy, The Netherlands, the UK and Ireland, and the USA with respect to the level of use of the Standards and compliance with the Standards by respondents' IAAs. There are significant levels of variation in responses by country. For Standards 1300, Quality Assurance and Improvement Program, and 2600, Resolution of Management's Acceptance of Risks, respondents indicate high levels of non‐compliance. Originality/value - This study compares the status of the use of the IIA Standards in five countries to determine if there is any difference in application in different parts of the world.
