Teacher performance plays a significant role in an educational institution which is explained by teacher leadership values. Teacher leadership models are developed by many and Katzenmeyer (2009) has developed a model of teacher leadership values consisting of 47 items distributed into 7 dimensions. The aim of this study was to re-examine that measurement model for teacher leadership with the respective dimensions and items and analyse the model applicability for the Generation Y teachers in Maktab Rendah Sains MARA, Malaysia. This study proposed a measurement model by implementing EFA and Structural Equation Modeling for the dimensions of teacher leadership which explain teacher performance. The specific model could be used by researchers to identify the best values of teacher leadership that explain teacher performance
