Standardizing a Test

    How does the USMLE or COMLEX standardize a test that is given multiple times a year? Do they only develop a bell shape curve for that day/week of test takers or do they have a plethora of questions that have been used in the pass with good score values to base a grading scale from? Hypothetically, say an average med. student took the test on the same day as a bunch of freakishly smart med students, his score would be lower than normal if they based it on just one day of testing. However if they had a Q bank of 5,000 qestions which had been answered on a regular bases they would be able to judge if somone correctly identified 80% of the questions, and the average student would not have to worry about being compared to the freaks who identified 100% of the questions (they would be outliers) on that one day. Would someone with some insight set me straight.

    (All guessing, but very logical...) Statistical analysis based on the average score on each question, thus generating a difficulty rating for each question. Your score would be based on which particular questions you got correct and which you missed... someone gave a pretty good explanation here as well if you search for it.
