I'm currently busy preparing for my CIA exams. However, once I finish those I will definitely want to top that up with the ISO Internal Auditor certification. How recognized is it internationally compared to CIA (Certified Internal Auditor) and how much is the certification?
Answer: Internal auditor certification is basically appropriate if you intend to work as internal auditor, and it doesn't have such visibility as e.g. Lead auditor certification. Both are recognized internationally, but the difference is in the level of knowledge (and status). I'm not very familiar with the Certified Internal Auditor, so I couldn't compare them.
