The Institute of Internal Auditors (IIA) is the recognized international standard setting body for the internal audit profession and awards the Certified Internal Auditor designation internationally through rigorous written examination. Other designations are available in certain countries. In the United States the professional standards of the Institute of Internal Auditors have been codified in several states’ statutes pertaining to the practice of internal auditing in government (New York State, Texas, and Florida being three examples). There are also a number of other international standard setting bodies.
Internal auditors work for government agencies (federal, state and local); for publicly traded companies; and for non-profit companies across all industries. Internal auditing departments are led by a chief audit executive (CAE) who generally reports to the audit committee of the board of directors, with administrative reporting to the chief executive officer (In the United States this reporting relationship is required by law for publicly traded companies).
History of internal auditing
The internal auditing profession evolved steadily with the progress of management science after World War II. It is conceptually similar in many ways to financial auditing by public accounting firms, quality assurance and banking compliance activities. While some of the audit technique underlying internal auditing is derived from management consulting and public accounting professions, the theory of internal auditing was conceived primarily by Lawrence Sawyer (1911–2002), often referred to as “the father of modern internal auditing”; and the current philosophy, theory and practice of modern internal auditing as defined by the International Professional Practices Framework (IPPF) of the Institute of Internal Auditors owes much to Sawyer’s vision.
With the implementation in the United States of the Sarbanes–Oxley Act of 2002, the profession’s exposure and value was enhanced, as many internal auditors possessed the skills required to help companies meet the requirements of the law. However, the focus by internal audit departments of publicly traded companies on SOX related financial policy and procedures derailed progress made by the profession in the late 20th century toward Larry Sawyer’s vision for internal audit. Beginning in about 2010, the IIA once again began advocating for the broader role internal auditing should play in the corporate arena, in keeping with the IPPF’s philosophy.
While internal auditors are hired directly by their company, they can achieve independence through their reporting relationships. Independence and objectivity are a cornerstone of the IIA professional standards; and are discussed at length in the standards and the supporting practice guides and practice advisories. Professional internal auditors are mandated by the IIA standards to be independent of the business activities they audit. This independence and objectivity are achieved through the organizational placement and reporting lines of the internal audit department. Internal auditors of publicly traded companies in the United States are required to report functionally to the board of directors directly, or a sub-committee of the board of directors (typically the audit committee), and not to management except for administrative purposes.
