Recent scholarship indicates several benefits of mother tongue education (MTE) in supporting student learning. Within one Mayan community in Guatemala, Ixil is the mother tongue spoken at home and faces extinction due to Indigenous oppression and genocide. This qualitative case study highlights efforts of 13 teachers and administrators at one primary school that took up the dual task of offering MTE and revitalizing the Ixil language. In order to gain a better understanding of Indigenous teachers' perceptions of language, culture, and MTE, this research was guided by the following questions: (1) How do teachers perceive their own understanding of attitudes and beliefs about language and culture? (2) How do they perceive their role in MTE and language revitalization? (3) Are teachers critical in their understanding of the importance of language revitalization and best practices for language pedagogy? Data was collected via site observations and surveys, then analyzed using constant comparative analysis. Themes that emerged included how teachers perceive their language revitalization and MTE agentive roles; how agency is expressed through the process of negotiating language and understanding through literacy; and addressing local priorities. Implications of the study and for future study are discussed.
