Item analysis catches problems test writers miss
Even experienced educators produce flawed questions on the first attempt. A review in the American Journal of Pharmaceutical Education found that post-administration item analysis consistently reveals questions that are too easy, too hard, or that fail to discriminate between students who know the material and those who don't. This isn't a failure of the test writer. It's a normal part of assessment design. The fix is built into most test maker platforms: review the stats after round one, revise the weak items, and your second version is always stronger.
