The curriculum in the Plateau Peoples’ Web Portal has been created by Tribal representatives from each of the partner Tribes. The basis of the curriculum is primary source material from national and regional repositories including the Smithsonian Institution, the Library of Congress, Washington State University's Manuscripts, Archives and Special Collections, Gonzaga University Archives and Special Collections and the Northwest Museum of Arts and Culture. These materials were used as part of the curriculum creation process along with newly create audio-video materials, animations, and interactive maps.

The curriculum is meant to aid educators and learners in various settings both formal and informal. Each tribal curriculum page includes an introduction providing the context and intention for the curricular materials.
