Teacher leadership is an increasingly popular concept to be implemented and utilized by practitioners and researches in their studies. Thus, the study aimed to determine the relevancy and applicability of Niche-Malaysian Teacher Leadership (NMTL) measurement model in Malaysian context. The NMTL measurement model which was originally consisted of 34 items with 7 principles, may address an early indication of the teacher leadership standards in the Malaysian classrooms. It was generated through literature review and comprehensive discussions with a group of schoolteachers. The measurement model was then distributed to the 169 schoolteachers, who were required to respond to a 7-point Likert scale. The respondents were selected through purposive sampling procedure. The collected data were analyzed using the SPSS version 20.0 and Amos version 22.0 software packages. An exploratory factor analysis (EFA) was conducted prior to performing confirmatory factor analysis (CFA). Thus, the NMTL measurement model should be able to clarify the standard of teachers’ leadership in Malaysian classrooms. Implications for the use of this instrument for further research are also explored.
