The document discusses item analysis, which evaluates test items and the test as a whole. It describes the U-L Index Method for conducting item analysis, which involves separating students into upper and lower scoring groups, tallying responses from each group, and calculating difficulty and discrimination indices. Difficulty index indicates how easy or difficult an item is, while discrimination index shows how well an item distinguishes high-scoring from low-scoring students. Together these can be used to interpret items and determine whether to accept, revise, or discard them. An example analysis is provided to illustrate the process.
