Abstract

The purpose of this study was to develop a scale that will measure teacher perceptions of the culture of teacher leadership in the school. Data for this study were collected from 347 teachers from primary schools in Burdur. The reliability, initially analyzed using Cronbach’s alpha, was verified by the Composite Reliability Coefficient. To investigate the validity of the scale, first- and second-order hierarchical confirmatory factor analyses were conducted. The two-step approach was adopted for examining the measurement model and following the structural model. Furthermore, convergent and discriminant validity of the resulting scales was verified using average variance extracted. The results showed that Teacher Leadership Culture Scale can be regarded as a valid and reliable instrument that can measure teacher perceptions about culture of teacher leadership in the school.

Key words: Teacher leadership culture, scale development, validity and reliability
