No, but I don't think it's really high. Everyone in my class made it it through. We all bonded pretty well and worked together. We have "training gates" at different stages through the process. You get extra help and some extra chances if you bust one. From what I heard it's a "three strike" kind of thing.

Bottom line is that if you study and put in the work, there is no reason you shouldn't make it through the program.
