This paper aims to analyse and scale mathematics data over time by applying the Rasch model using the QUEST (Adams and Khoo, 1993) computer program. The mathematics achievement of the students is brought to a common scale. This common scale is independent of both the samples of students

tested and the samples of items employed. The scale is used to examine the changes in mathematics achievement of students in Australia over time.

Conclusions are drawn as to the robustness of the common scale and the changes of students' mathematics achievement over time in Australia.
