If you give a test and a great majority got a certain question wrong, you can look at the question and figure out why they may have missed it. You can use this information to reteach certain areas, or go over the reasons students didn't understand the question.
This form of reporting also allows you to see how the students are doing in different strands or standards together. You can do item summaries and look at how the kids did on all the items. You can figure out if the question was asked in a way the kids didn't understand and figure out how they are doing on the tests. It also allows you to see if a standard is being given only one question, or if it has multiple questions for that standard. Then you can see how the students are understanding that standard, or if there weren't enough questions on that standard to give an idea of how well they grasped that standard.
