This article reports on the development and initial validation of the multidimensional Multicultural Teaching Competency Scale (MTCS). Data from 506 pre- and in-service teachers were collected in three interrelated studies. Exploratory factor analysis results suggested a 16-item, two-factor solution: (a) multicultural teaching skill and (b) multicultural teaching knowledge. Confirmatory factor analysis suggested that the two-factor model was a good fit of the data and superior to competing models. The MTCS demonstrated adequate internal consistency and was related in meaningful ways to measures of racism awareness and multicultural teaching attitudes. Participant responses were not associated with social desirability. Implications are discussed. (Contains 1 note and 3 tables.)
