BACKGROUND: The International Baccalaureate Middle Years Programme (IBMYP) aims to produce a holistic transformation with creative and critically minded students. However, very little attention has been paid to the development of an instrument to measure the IB learner profile with good psychometric properties. PURPOSE: This study aims to develop an instrument with good psychometric properties, based on the Rasch measurement model and confirmatory factor analysis. METHODS: The study consists of two phases of pilot and field studies involving 597 year four students from IBWS MOE. RESULTS: The findings from the Rasch measurement model analysis have shown that 54 items meet the criteria of the item fit, unidimensionality, and reliability index. Meanwhile, confirmatory factor analysis found that 44 items have shown a valid item fit index. CONCLUSIONS: The combination of both analyses has sho...
