Abstract In this paper, I draw on the ethnography of language planning and policy to consider how urban Indigenous language education might benefit from understanding the meanings and processes behind other language planning and policy activities migrant youth participate in, specifically, family language policymaking activities. Drawing on ethnographic fieldwork and interviews conducted in the region of Cusco, Perú I examine the experiences of two youth from rural hometowns and of their families. My analysis discusses how family language policies influenced youth’s shifting repertoires towards and away from Quechua, how youth drew on their Quechua–Spanish bilingualism to act as family language policy agents guided by local crianza and raciolinguistic ideologies, and how youth experienced Quechua language education in urban high schools. I argue that urban Quechua education efforts need to consider how migrant youth experience and shape their bilingualism and that of their families across rural-urban continua in order to craft safe and meaningful spaces where youth can participate in the strengthening of their Quechua language practices and identities.
