This paper describes the construction and empirical evaluation of a new scale for measuring educational leadership styles of principals/supervisors/coordinators as perceived by teachers in schools. The respondents of the study are 500 school teachers from the city of Bangalore. The data was subjected to various statistical procedures to establish the reliability and validity of the scale. Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy (0.876) and Bartlett's Test (p=<0.001) suggested that PCA could be undertaken. PCA analysis extracted seven factors with a cumulative 63.149% variance. Cronbach's alpha of the 31 items scale was 0.906. Convergent validity, discriminant validity, nomological validity, Variance Extracted (VE) values, Average Variance Extracted (AVE) values and Squared Multiple Correlations (SMC) between the seven factors were examined and reported. The results show that the evidence for construct validity and reliability is favorable for the Educational Leadership Styles Scale (ELSS). Definitions for the factors of ELSS are offered in this paper. [ABSTRACT FROM AUTHOR]
