Books and IIA Material

The sources below give you an idea about useful additional essentials.

Get the current edition if you can - for preparing the exam a previous edition may be good enough.

Reding et al Internal Auditing


IIA Material

Reading and understanding the IIA Code of Ethics, IIA Standards and IIA Practice Advisories is strongly advised for preparing CIA part 1 and part 2. > link

Do not forget to have a look at the IIA's exam brochure. > link  


Internal Auditing Textbooks

The IIA recommends the extensive Sawyer (2012) textbooks and Reding et al (2013) which aims at students and novice practitioners.

An experienced practitioner would probably prefer the hands-on approach of Pickett (2010).
