Unit 5: Item Analysis

An item merely written is not complete. Once an idea for a test item has been conceived and articulated according to the rules for writing good items, the important task of determining its quality remains. If it is flawed, it must be improved or discarded. To accomplish such analysis for items, the writer must employ a precise methodology to systematically uncover information about an item, and then make judgments about it based on that information.
