Laine Bradshaw, Ph.D.

I am an Ass​ociate Professor of Quantitative Methodology in the Educational Psychology Department at the University of Georgia. My research focuses on psychometrics, specifically on diagnostic measurement using contemporary item response models called diagnostic classification models (DCMs). My research efforts seek to refine statistical methodology to enable assessment results to provide useful information about students’ complex knowledge structures, including concepts they understand as well as misconceptions they have.
