David Andrich has made substantial contributions to quantitative social science including seminal work on the Polytomous Rasch model for measurement, which is used in the social sciences, in health and other areas. He is currently a Winthrop Professor at the University of Western Australia, where he holds the Chapple Chair in Education. He was elected a Fellow of the Academy of Social Sciences of Australia in 1990 for contributions to measurement in the social sciences . David Andrich spent time working with Georg Rasch in Denmark and Australia. He is one of the most prominent advocates of Rasch's probabilistic measurement models.
