to tell or not to tell
the problem will telling FAIL last is that the recepient is not expcting to fail, and thus will wonder why the debrief was not negative in content.
The debrief must reflect the "errors", and the marginal, and the acceptable, if any one error is enough to warrant a fail then say so.
The UK CAA spent two weeks teaching just how to say FAIL....I do not have my notes, but the concelt is: that the standard demonstrated today has not reached the required standard.
As an aside the UK CAA also went to great lengths to ensure that if there was any room for doubt the candidate should be given the benefit.
Just my 1P worth.... Bumz
