Based on need for intercultural approach to cultural and linguistic diversity in primary school students, this article shows racist attitudes and discrimination against rural, Andean and Quechua context in culturally different social groups. This situation raises the following question: how do the intercultural competences of primary school teachers manifest themselves in urban context of Huaraz city, Peru? Methodology used is educational ethnography with interpretative, sociocritical and humanistic features, whose design and development are summarized in three moments: pre-configuration, configuration and reconfiguration of reality. Also, theoretical, and empirical methods such as the participant observation and the in-depth interview applied to teachers were used. Findings refer presence of rural students who speak Quechua in the school; shortcomings in the approach to intercultural diversity; and shortcomings in intercultural competences of urban teachers. Finally, we conclude there is a need to develop intercultural competences in teachers to ensure an education and intercultural society.
