Multicultural education is "a democratic approach to teaching and learning that seeks to foster cultural pluralism within culturally diverse societies and an interdependent world." Multicultural teacher education is the effort to produce professional educators who are both committed to the ideals of multicultural education and competent in their practice of it. Just as personal teaching efficacy (the confidence that one can effectively teach children) has been shown to be an important teacher attribute, teachers need similar confidence to be effective in multicultural settings--a concept of multicultural efficacy. The Multicultural Efficacy Scale (MES) was developed as a tool for measuring this concept, along with the multicultural teacher education dimensions of intercultural experiences, minority group knowledge, attitudes about diversity, and knowledge of teaching skills in multicultural settings. In this article, the authors describe the development, item selection and the validation results of the MES. (Contains 1 table.)
