We average about 1-2 no shows in a class of 35.

As far as training failures, the percentage is pretty low, but variable. If you show up for an oral and don't know the memory items or limitations, you fail. Period. That is stuff you start on day 1.

If you can't fly an airplane in the sim and don't belong in the cockpit, you fail.

But, if you put forth effort and try, you will pass. I don't know of anyone that has failed and did not deserve it.

The training department would absolutely love a 100% pass rate if it is deserved. Sadly, it isn't.
