CASI isn't just about "completing things on the list" if you will. They also look at the rider and see if they can do things competently. If you're ever in doubt, see if you can find an evaluator and go for an afternoon ride with them. I had thought I was ready for my level 2 until I went riding with them, and oh boy was I ever in for a surprise.
And congrats OP, where did you get your cert?
oh i looked at the aasi list. but either way im sure its not just completing the list. rider attitude and general skill are probably the biggest factor, but it is still just a place to start to see if i would have the skill set needed.
