Dr Stephanou worked for the Australian Council for Educational Research (ACER) from 1989-2016 with responsibilities for the psychometrics and analysis of large scale examination data. This work included the preparation of random samples and equating designs, the construction and description of Rasch measurement scales, the provision of psychometric advice and explanation of measurement concepts, data analysis with a variety of software, multilevel modelling, the preparation of assessment materials and reports, and the explanation of results through high quality graphical presentations.

He authored numerous educational measurement publications and conference presentations.
