Our societies are going through a process of continuous transformation. The challenges and opportunities of diversity and globalization can only be addressed if civic education and intercultural education are interrelated. More often than not, there is a lack of coherence between educational practices based on these approaches. Moreover, even if the principles and methods of civic and intercultural education are used for international as well as local development, very seldom their impact is measured through the means of scientific research. In this study, a methodology of civic and intercultural education was piloted, and its impact was measured regarding teachers' and students' attitudes toward Roma. We measured the acculturation orientations and stereotypes of teachers and students involved in a civic and intercultural program. The results show that there are changes in both teachers' and students' attitudes toward Roma.
