Differential Item Functioning Meeting

During this meeting, an exercise will be conducted to review items that have been statistically flagged as potentially containing construct-irrelevant bias.

March 23, 2023

Differential item functioning occurs when a subgroup of the population has a different probability of correctly answering a question than another subgroup. Dedicated volunteers from all areas of pharmacy practice review items that have been statistically identified as functioning differently to determine whether any substantive bias exists.
