From Jim Goodell (jimgoodell@qi-partners.com)

To consider for Ed-Fi 1.2…or some point in the future… For the Assessment Results Use Case, it is most valuable from an instructional point of view when the teacher and students have access to item analysis including the ability to drill down to assessment item itself. For multiple choice items it is valuable to see how many in a class/school got the item wrong, but also to see the common wrong answers in an item analysis. The same for fill-in problems e.g. To see that 50% of the class entered the wrong answer, is not as valuable as being able to drill down and see that half the class entered a wrong answer of "6" when the correct answer was "5"…and that isn't valuable unless they also know that that the item was "3 + 2 = __", with that information the teacher and students can see that half the class didn't pay close attention to the operator and assumed it was a multiplication problem.

I've heard from educators who got strand scores and item level test results linked to standards but did not have access to the items…one story was that everyone in the class did well on the multiplication problems, but a few problems problem linked to the multiplication standard stumped them all; the students were stumped by a problem that asked them to "find the product of…"; only by researching the problem after the test was released did the teacher realized that he had taught the operation, but had not sufficiently taught the terminology.
