Han-Hui Por

Han-Hui Por, a senior psychometrician at ETS, tackles technical and operational psychometric issues in large-scale assessments. Her research interests focus on fairness issues in assessments and recent projects include investigating the reliability of human raters’ scoring, examining the psychometric properties of new item types, and exploring issues of fairness and equity in assessments using process data. 

She started her career in educational assessment as a researcher with Singapore's Ministry of Education, where she evaluated the feasibility of investing in new and existing education programs to meet the needs of students, teachers, and the community. Prior to ETS, she was the lead statistician for a New York City Housing Authority study assessing the impact of housing assistance on economic self-sufficiency in New York City. She has also coauthored several papers on the public’s understanding and communication of uncertainty and her work has been highlighted by the InterAcademy Council in a report to the United Nations.  

Por received her Ph.D. in psychometrics and quantitative psychology from Fordham University, an M.S. in applied measurements from the University of Illinois Urbana-Champaign, and a bachelor's in psychology and economics from the National University of Singapore.
