Daniel Koretz is an expert on educational assessment and testing policy. A primary focus of his work has been the impact of high-stakes testing. His research has included studies of score inflation, the effects of testing programs on educational practice, the assessment of students with disabilities, international differences in the variability of student achievement, the application of value-added models to educational achievement, and the development of methods for validating scores under high-stakes conditions. His current work focuses on the equity implications of high-stakes testing, the effects of high-stakes testing on postsecondary outcomes, the characteristics of traditional tests that encourage inappropriate test preparation, and the design and evaluation of new testing designs tailored for accountability. Koretz is a member of the National Academy of Education and a Fellow of the American Educational Research Association. His doctorate is in developmental psychology from Cornell University. Before obtaining his degree, Koretz taught emotionally disturbed students in public elementary and junior high schools.
