Previous studies (e.g., Abedi, 1997) have confirmed the contribution of dimensionality assessment in ascertaining the internal structure of the test and making decisions concerning reporting the part-scores. The present study aims, first, to explore, the dimensionality structure of an admission test in an ESP context in Iran when it is made up of both general and specific purpose components; and second, to calibrate the items with that model of item-ability parameters estimation which best constrains the items as to the dependency between items and dimensionality. This study has implications for assembling a joint general-specific purpose test in one module and scoring it meaningfully under a special Rasch multidimensional model and its constraints.
