Three Issues in Modern Test Theory for the Next 10 Years

This paper discusses three key issues in modern test theory: multidimensionality, multi-level modeling, and enhancing uses at the individual level. The author explores topics such as estimating scores, multidimensional computerized adaptive testing, patient/provider nesting, meaning of theta, clinician care, regulators' role, responders, individual standard errors, confidence intervals, and person fit.
