TheInstitute of Internal Auditors (TheIIA) is an internationalprofessional association.[3] The IIA offers professional certifications and provides standards for theinternal audit profession.
The IIA was established in November 1941. The first five chapters were founded in five cities the following year. The first international chapter was established inToronto in 1944. Additional international expansion outside North America occurred inLondon andManila in 1948, with chapters inJapan andAustralia in 1952.[4]
The IIACode of Ethics was formally adopted in 1968. A common body of knowledge followed in 1972. The Certified Internal Auditor examination was established in 1974.[5] The IIA first issued professional standards, theStandards for the Professional Practice of Internal Auditing, in 1978.[6] In 1985, The IIA was one of the original sponsors of theCommittee of Sponsoring Organizations (the Treadway Commission).[7]
In 2025, The IIA had more than 260,000 members from over 170 countries and territories.[4] The IIA's global headquarters are inLake Mary, Florida.[8] Anthony Pugliese is the President and CEO of the organization.[9]
The Certified Internal Auditor (CIA)[10] certification is the primary professional designation offered by The IIA. The CIA certification is a globally recognized designation.[11]
In order to become a CIA, candidates must pass the three-part CIA exam as well as meet certain educational and professional experience requirements stipulated by The IIA.[12] The IIA also offers the CIA certification through a one-part exam, called the CIA Challenge Exam,[13] for those who are already aCertified Public Accountant,Chartered Accountant, or Certified Information Systems Auditor.[13]
CIAs are annually required to earn continuing education hours to renew their certifications.[14]
As of December 31, 2021, there were 178,512 holders of the CIA designation. Almost half were in the Asia Pacific region (85,604), with North America coming in second (57,482).[15]

In 1978, the IIA released the first version of theStandards for the Professional Practice of Internal Auditing.[6] After several updates since then, on January 9, 2025 the revisedGlobal Internal Audit Standards took effect. The revised standards replaced theInternational Standards for the Professional Practice of Internal Auditing.[21]
The newGlobal Internal Audit Standards contain domains, principles, and standards. The five domains include an overview of internal auditing’s purpose, ethics, overall organizational governance, chief audit executive responsibilities, and audit performance.[22] The 15 principles are broad statements within the last four domains.[23] The 52 standards provide greater detail for the principles and include requirements, considerations for implementation, and examples of evidence of conformance.[22]
