This article reports on the development and initial validation of the Culturally Responsive Classroom Management Self-Efficacy Scale. Data from 380 preservice and inservice teachers were used to examine the psychometric properties of the instrument. Exploratory factor analysis results suggested a one-factor structure consisting of 35 items and the scores on the measure were highly reliable. Evidence of construct validity was obtained with two existing teacher self-efficacy measures. The results of the correlational analysis lend credence that the instrument developed by the research team was indeed measuring self-efficacy beliefs. The implications for teacher education and research are discussed.
