Following an exam administration, Yardstick often produces an Item Analysis report from their proprietary software called COGs. The item analysis report provides information about each item in terms of its difficulty, discrimination, and the distribution of responses across alternatives.

Our Senior Psychometrician Dr. Michaela Geddes, PhD. has written a handy backgrounder that focuses on a common comment from this report that reads “Item is making a limited contribution to the measurement capability of the test.” Dr. Geddes unpacks what it means, and what you should do if you see it on your report.
