The Indigenous Fluency Transfer System and Curriculum is a comprehensive, sequenced curriculum project designed to help new learners become proficient in their Indigenous or endangered language. This system uses a communicative approach, and focuses on new learners being able to effectively communicate in their language. Taught in full immersion from the first lesson, the curriculum progresses in spirals, which means that each topic is revisited with increasing complexity throughout the levels. At its foundation are hundreds of hours of audio recordings from fluent Elders or proficient speakers. These recordings form the core support for learners.
Each of the four levels consists of two books: a language instruction book, and a literature (story) book. Immersion teaching support is provided with a direct acquisition teacher's manual containing immersion teaching activities for the lessons.
