Educational Testing Service

Paul W. Holland held the Frederic M. Lord Chair in Measurement and Statistics in the Research and Development Division at the Educational Testing Service (ETS) in Princeton, New Jersey until he retired in 2006. His educational background includes a MA and PhD in statistics from Stanford University and a BA in mathematics from the University of Michigan. His association with ETS began in 1975. In 1979 he became the director of the Research Statistics Group. In 1986 Holland was appointed ETS's first distinguished research scientist. He left ETS in 1993 to join the faculty at University of California, Berkeley, as a professor in the Graduate School of Education and the Department of Statistics, but returned in 2000 to ETS. He has made significant contributions to the following applications of statistics to social science research: categorical data analysis, social networks, test equating, differential item functioning, test security issues, causal inference in nonexperimental research, and the foundations of item response theory. His current research interests include: kernel equating methods, population invariance of test linking, and causal inference in program evaluation and policy research.
