David Andrich is an Australian academic and assessment specialist. He 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. Andrich 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. Andrich also worked with Georg Rasch in Denmark and Australia. He is one of the most prominent advocates of Rasch's probabilistic measurement models.
In 1990 and in 1993 and 1996, Andrich was appointed a Visiting Professor at the University of Trento in Italy for periods of two months.

He continues to teach educational measurement. He is especially known for his work in item response theory, with a particular focus on Rasch models for measurement. His research and work ranges from the philosophy of measurement, through model developments, exposition and interpretation, to software development. He has published in Educational, Psychological, Sociological and Statistical journals. He is the author of Rasch Models for Measurement and coauthor of the software package Rasch Unidimensional Measurement Models. He has published extensively in areas ranging from Rasch models to philosophy of science. Some of these publications are listed in articles on the Rasch model and polytomous Rasch model. Andrich has organized a series of conferences on Rasch measurement models hosted in Perth, Western Australia, which have attracted researchers from a wide array of countries. He has held major grants with the Australian Research Council continuously since 1985. As recognition for his works, he was awarded the Susan Colver Rosenberger prize for his research while completing his PhD at the University of Chicago.
