I'm not familiar with RH's exam, but it may be that making the exam 
"psychometically measurable" would also make it less useful.

Yes, multiple choice test absolutely suffers from this. I can say that 
because I've been a testee many times. If I can't concentrate because my 
gf broke up with me or I have a cold that'll hurt me just as much on a 
multiple choice.

I'll have to give this some thought. Thanks for the explanation. It's 
much better than I thought.

That's how I understood what you wrote. You listed clerical staff, 
proctors and transportation and said that this made it necessary to 
charge $100. Sorry if I misunderstood.

I admit that's pretty lean.

INGOTs has 5 staff for the UK. 1 clerk, 1 techie (that's me) and 3 
moderators (one of the moderators designs the criteria). This covers 
2600 pupils in the UK distributed over 50 academies. That's thanks to 
the large network of assessors (whom we train) who do most of the work.

Who are Prometric and Thomson Vue? Why do they take such a big chunk of 
the exam? I guess that the $100 is not bureocracy after all...
