mfin27,
I get what you are saying, the problem I have with percentiles(even though the probability is slim) is what you had mentioned about others being disadvantaged given a certain environment.
Obviously smarter people than myself have thought about this and likely come up with the best solution using the Angoff method, it does suck that we don't really have at least a general reference if we can't use the top 1% method as a guide. The Angoff method should theoretically take into account if a test is harder or easier because the experts would either say that the minimum qualified candidate would know say 168 questions for an easy test and 156 for a hard one(just as an example).
My guess is in reality they use a combination of the two methods to come up with a reasonable outcome and check against one another for a conflict. If the top 1% was scoring 90% and so 63% is the pass according to that standard, if the panel decides that the minimum qualified candidate should get 65% right, then they could say "wait a minute" and come up with a compromise, assuming a 2% deviation is out of ordinary and cause for concern of course.
I hear people saying that this test was easier and I agree but I agree because it was my second time taking it so I am also better prepared so I am biased and it should seem easier. I assume they know how to properly write the test and make it fairly consistent.
Prob just semantics at this point. ;-)
