The mission of Lillian Vallely School is to help Native American children, grades K–5, build a bridge to their future success educationally, socially and spiritually through a quality education consisting of academics, Shoshone/Bannock cultural preservation, and basic Christian values. The measure of success is to expand a student’s ability to navigate Native and non-Native cultures, "to compete academically, to use academic helpers like and to become a constructive influence at home and in the community."
