Abstract

The validity of score interpretations from low-stakes tests is plagued by low examinee engagement. Recently a promising IRTree model was proposed to adjust ability estimates for disengagement, with a noted need for critical evaluation. We conducted a comprehensive simulation study to investigate the accuracy of parameter estimates under varying conditions.
