ISACA sure doesn't make it easy to find the list of languages in which the CISA exam is available: Prepare for the CISA Exam You should read through the 2013 Candidate’s Guide to the CISA Exam and Certification bulletin. I don't see the 2014 CISA bulliten.
Thanks a lot JDMurray, Although I can take the exam in my language, I think I'll take it in english language because most documentation about CISA are in english language. Best regards and happy new year. Bagabu
