Abstract
![CDATA[In recent times, there has been an increased interest in the use of the multilevel Rasch model in medical, educational and psychological testing. In the Rasch multilevel model, the first level entails item responses, which rely on item variation and person ability; the second level describes variation and covariation between person ability within school and the third level describes variation and covariation between schools. While, the Hausman test for the multilevel Rasch random effect with intercept is the shape differences in item difficulty parameter estimates from the two and three level Rasch method. In this study, the Hausman test for the multilevel Rasch model was presented using data set from the second International Association for the Evaluation of Educational Achievement (IAEA) mathematics study for high school pupils in Australia. The sample consisted of 10 dichotomously-scored items from 50 students drawn from two stage sampling and only year 9 students with completed information were used for the analysis. The main findings were that the Hausman test suggested a statistical difference in item difficulty estimates between two and three-level Rasch model and ignoring the effect of clustering will result in biases when interpreting item difficulty parameter in Rasch measurement model.]]
