The Item Analysis Report is a powerful way to see how students did by item, by standard, and many other ways to look at the test results. It would be a good report to use at a PLC meeting where you can see if a majority of students missed the same questions, you could try another strategy for teaching that concept and have them take a similar test to see if they fare better. You could also analyze the questions that a majority answered correctly to look at how you taught that concept since it was successful and duplicate it on the ones where they weren't successful.
