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, and to become a constructive influence at home and in the community.
The Lillian Vallely School is a private non-profit elementary day school serving Native American children who live on the Fort Hall Reservation in Southeastern Idaho.

The school is a fully accredited private school through The National Private Schools Accreditation Group (Orlando, Florida).
