In 1986, he spent a further six months at the University of Chicago.[4]

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.

During that time, he was the Dean of Education at Murdoch University from 1988-1990 inclusive, and from June 2003 until end May 2005. In 2007, he returned to The University of Western Australia as Chapple Professor of Education.

Andrich has been a member of editorial boards for a number of journals including Psychometrika (1995–2003), Applied Psychological Measurement (1986-), the Journal of Educational Measurement (1984–1989) and Australian Journal of Education (1990–1993). He has written a number of reports for both the state and federal governments, and in 1990 he was made a Fellow of the Academy of Social Sciences of Australia for his contributions to measurement in the social sciences. 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 (Sage) and coauthor of the software package Rasch Unidimensional Measurement Models (RUMMLab). 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.[5] He has held major grants with the Australian Research Council continuously since 1985.[6] 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.[7]
