Established in 1941, the Institute of Internal Auditors aims to provide global leadership for the profession. Based in Florida, the Institute is the internal auditing industry’s recognized authority across the world and is keen to promote the profession through improved education. The Institute’s membership base covers 165 countries, with members spread across professions such as risk management, corporate governance, information-technology auditing and education, as well as mainstream internal auditing.

The objective of the Institute’s code of ethics is to create an ethical culture throughout the profession. The Institute’s members aim to help organizations to achieve their objectives through disciplined and highly systematic efforts to strengthen their governance, control, and risk-management procedures. The code of ethics not only covers the core activity of internal auditing but also extends to cover principles relevant to the profession, as well as the rules of conduct to which practitioners should adhere.

  • The code of ethics helps to ensure the objectivity of internal auditors, aiming to assist them to assess all relevant factors without being unduly influenced by others or by their own interests.

  • By defining the standards expected of internal auditing professionals, the code helps to reinforce the trust that forms the main foundation of the profession. The code also aims to ensure that individual internal auditors have the required competencies to cover the particular task they are expected to perform.

  • The confidentiality element of the code aims to make certain that internal auditors always appreciate the value of information. It underlines their requirement to safeguard information at all times, subject only to legal or professional obligations.

  • The Institute has disciplinary procedures in place for instances where members are accused of violating the code of ethics, helping to ensure that members can be trusted to act in a consistently professional manner.

  • Ethical standards in business can vary widely from country to country. Therefore, auditing professionals in some countries may have to work harder than those in other countries to fully achieve all the standards expected of a global code of ethics.

  • Cultural differences between companies could also put more pressure on internal auditors in some organizations to adhere to the consistently high standards demanded by the code.
