This paper investigates the relationship between meso university language policies in Puerto Rico and their micro instantiations in an undergraduate psychology classroom. We describe a typology of language policies used by 38 universities and campuses in Puerto Rico where their openness allows for flexible implementation of everyday micro policy. We then focus our attention on a linguistic ethnography of a psychology course where translanguaging practices reify and disrupt accepted classroom language ideologies in Puerto Rico.
