Item Analysis (a.k.a. Test Question Analysis) is an empowering process that enables you to improve mutiple-choice test score validity and reliability by analyzing item performance over time and making necessary adjustments. Knowledge of score reliability, item difficulty, item discrimination, and crafting effective distractors can help you make decisions about whether to retain items for future administrations, revise them, or eliminate them from the test item pool. Item analysis can also help you to determine whether a particular portion of course content should be revised or enhanced.
