Quality Management of Test Questions and better Editorial support

Who of you sat an exam with unintelligible questions? Everybody!
At some point in time everyone was presented with ambiguous or downright screwed questions in an exam.  It feels terribly unfair.  

There is a dire need to evaluate the quality of test questions. Empirical data on question performance should be made available thus question authors can improved their question based on this information.
