These figures are usually attributed to such factors as the absence of schools within the vicinity of indigenous communities, the prohibitive costs of education according to the standards of indigenous peoples, the lack or inadequacy of specialized infrastructure and teaching staff, discrimination and exclusion of indigenous interests from curricula. There is a need for improved State and civil society engagement with indigenous peoples at local and national levels. National curricula and materials should be intercultural and include accurate information regarding indigenous peoples, their cultures, histories and experience.
