In this article, we report the development and psychometric validation of the Teachers' Receptivity to Change Scale (TRCS). The sample included secondary school teachers of Kerala, India. In India, the teachers' receptivity to change becomes important in the context of the newly drafted National Education Policy, (2020) which places teachers' at the center of the reforms. The present study proceeded through five phases namely item analysis, exploratory factor analysis, confirmatory factor analysis, validation of the scale, and test-retest reliability. The development of the tool started with the generation of a pool of items followed by item analysis. The exploratory factor analysis extracted four factors and the confirmatory factor analysis confirmed the four-factors namely individual, organizational, educational, and bridging factors. The structural equation modelling established the four-correlated factor construct of teachers' receptivity to change and an additive model indexing teachers' receptivity to change as the sum of the four factors. Both the model fit indices indicated an excellent fit. The validity of the TRCS established by correlating the teachers' receptivity to change and its factors with multidimensional work motivation scale and engaged teachers' scale indicated a moderate correlation. The final 28 item TRCS showed adequate internal consistency (Cronbach's alpha = 0.897) and discriminant validity. The test re-test reliability analysis (Cronbach's alpha = 0.884) confirmed the temporal stability of the scale. The findings recommend a psychometric reliable and valid scale for assessing teachers' receptivity to change with implications for teachers, researchers, and policy makers.
