Abstract

This paper is concerned with the analysis and scaling of mathematics achievement data over time by applying the Rasch model using the QUEST (Adams & Khoo, 1993) computer program. The mathematics achievements of the students are 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 30 years from 1964 to 1994. Conclusions are drawn as to the robustness of the common scale and the changes in students' mathematics achievements over time in Australia.
