This article addresses teachers’ uptake of Black and Latina/o youth linguistic repertoires within the official space of an English Language Arts (ELA) classroom and how youth respond to corrective feedback that is focused on the form of their messages, rather than their function. Corrective feedback offered by one Latina teacher indexed larger standard language ideologies that circulate within urban Black and Latina/o schools. I argue that youth’s responses to corrective feedback point to their emerging critical meta-awareness, given their alignment against narrow conceptions of what counts as language for schooling and learning.
