Quantitative item analysis examines test items statistically to determine difficulty and ability to discriminate between high and low performing students. Qualitative item analysis examines items for flaws through expert review. Both help improve assessment and learning by identifying flawed items for revision or removal. Without analysis, tests may contain errors that invalidate scores or fail to accurately measure learning. Teachers should use both to ensure items are high quality and assessments provide meaningful feedback.

Item Analysis. Explain quantitative item analysis and qualitative item analysis.
What are their benefits to learning and assessment? What are the risks to
learning and assessment if these types of analyses are not administered? Finally,
provide two examples of imperfect test items for your peers to qualitatively
analyze. Explain why you think it is necessary for teachers to use a combination
of both qualitative and quantitative item analysis. Respond to at least two of your
peers, identifying the errors in their listed test items, and providing suggestions on
how they can be improved
