In the Fall of 2022, the NLP, the Department of Language, Literacy, and Sociocultural Studies (LLSS), and the Department of Native American Studies (NAS) collaborated to start the Diné Language Teacher Institute (DLTI). The DLTI offers undergraduate and graduate students who speak Navajo the opportunity to enroll in a unique teaching certificate program. This certificate aims to equip future Diné language teachers to use immersion methodologies when promoting the use and preservation of the Navajo language in their communities.
