I took the ICC Residential Inspector exam in Idaho. I assume it's pretty much the same test. There is an online study course you can take through ICC Campus, but to be honest, the free code quiz offered at Mike Holt's web site was the best study guide I used. The residential exam was pretty basic and easy to pass if you know your code book. The Commercial Inspector exam was a little tougher because it involved some blueprint reading and several calculations. Good Luck
