Have to do it every five years. I have to show courses taken in continuing ed., conferences attended and PROOF that I actually went to them, like airline tickets, hotel room bills, etc. This is to show you didn't just pay the conference fee and never showed up.
I know more than one CIH who got their cert. yanked because he or she didn't have the backup documentation for an audit. I worked hard to get it, and I can't imagine the thinking of those who lost theirs because they didn't do their paperwork and document it.
Anyway, no biggie, but I'm good for another 5 years. I plan to retire in about 7 years, so one more recert in 2017.
