This study aims to calibrate the measurement instrument which is used for the analysis of the criteria of sustainable construction. To meet the objective, Rasch measurement model has been applied to identify the misfit data through analysis of fit and unidimensionality, where the reliability and validity of the measurement items were determined and the misfit data were identified and reviewed to enable a more accurate and meaningful analysis. With the conduct of fit and unidimensionality analysis as part of the measurement model processes, the objective to calibrate the measurement instruments that would enhance the quality of the instrument in measuring the construct was able to be implemented. Due to that, the identification and removal of the misfit data as part of the analysis process, is a strong statistical justification for this study which improved the reliability of the items, and indirectly serves the purpose of instrument calibration to ensure a more accurate measurement.
