"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.
