"I encourage everyone in my internal audit unit to take the IIA's qualifications"

Brian Moreland CMIIA

The advice, training and support from the Institute have been invaluable since I joined as a trainee internal auditor. I have taken a keen interest in the increasing emphasis on professionalism.

I encourage everyone in my internal audit unit to take the IIA's qualifications as they are second to none in providing a solid foundation for the provision of an effective service to management.

IIA Diploma

Registration will permanently close on 22 June 2015

We are phasing out the IIA Diploma and introducing the Certified Internal Auditor (CIA), which is a globally-recognised certification. 

Registration for the IIA Diploma will remain open until 22 June 2015 and we will continue to support students with tuition. The final study session will lead to exams in November 2017. PEJ submissions are due by 1 May 2018, at the very latest.

Members who pass the IIA Diploma will earn the PIIA designation and will also be eligible to accept the CIA designation. 


To register on the IIA Diploma you must have either an undergraduate degree or have your application endorsed by your employer confirming your ability to take on postgraduate level studies.

Studying for your qualification 

There are five theory modules to complete and you will be assessed by exams and your Professional Experience Journal (PEJ).

Tuition is compulsory when you study the IIA Diploma, unless you are studying the accelerated route. Our in-house tuition provider, IIA Learning, offers a range of options, including face-to-face tuition and a distance learning programme to support you. 

Most people take around two years to complete the qualification. 

IIA Diploma - accelerated route 

If you hold a postgraduate qualification and have been working in internal audit for three years, you may be eligible for the accelerated option.
