I have been studying to take the test for a couple of months and feel I am almost ready. Although I must admit the only reason I am doing it is to get a raise at work! There is valuable information in the study guide and on one hand I feel like the ISA is a good thing. On the other hand it seems to be a money grubbing institution, like the TCIA. A lot of the info in the study guide seems a bit dated and other stuff is pretty vague. I have worked with certified guys that didn't know their a$$ from a hole in the ground who simply regurgitated a bunch of info from the study guide. Ethics, morality and intention are a whole lot more important than paying into the ISA. With that being said, wish me luck on the test cuz I need a raise!
