Editing Navajo language (section)

===Education===
The Navajo Nation operates Tséhootsooí Diné Bi'ólta', a Navajo language immersion school for grades K-8 in [[Fort Defiance, Arizona]]. Located on the Arizona-New Mexico border in the southeastern quarter of the [[Navajo Reservation]], the school strives to revitalize Navajo among children of the [[Window Rock Unified School District]]. Tséhootsooí Diné Bi'ólta' has thirteen Navajo language teachers who instruct only in the Navajo language, and no English, while five English language teachers instruct in the English language. Kindergarten and first grade are taught completely in the Navajo language, while English is incorporated into the program during third grade, when it is used for about 10% of instruction.<ref>{{cite web|title=Tséhootsooí Diné Bi'óta' Navaho Immersion School|url=http://ourmothertongues.org/language/Navajo/8|access-date=15 August 2015|archive-url=https://web.archive.org/web/20150905223432/http://ourmothertongues.org/language/Navajo/8|archive-date=5 September 2015|url-status=live}}</ref> In the 2020s, the language nest Saad K’ildyé was established near Albuquerque through a non-profit Diné-led organization. The school also offers classes to parents and family activities revolving around Diné culture.

After many Navajo schools were closed during World War II, a program aiming to provide education to Navajo children was funded in the 1950s, where the number of students quickly doubled in the next decade.<ref name=":0" /> According to the Navajo Nation Education Policies, the Navajo Tribal Council requests that schools teach both English and Navajo so that the children would remain bilingual, though their influence over the school systems was very low.<ref name=":0" /> A small number of preschool programs provide a Navajo-language immersion curriculum, which teaches children basic Navajo vocabulary and grammar under the assumption that they have no prior knowledge in the Navajo language.<ref name=":0" />
