The Lakota Language Consortium is the driving force behind LSI. Its comprehensive plan for Lakota language revitalization calls for teacher development and support as the balance to having new teaching materials – because textbooks and dictionaries don’t create new fluent speakers all by themselves. Because LLC is a collaboration between five tribes and a team of academic linguists and language educators, the Consortium has worked to connect the Lakota revitalization effort with the entire professional second-language education field in the rest of the country.
