Government
The Alamo Navajo School Board (ANSB), federally funded, was used as a vehicle to have public works projects without needing to involve the Navajo Nation bureaucracy. Cindy Yurth of the Navajo Times wrote that it is "the de facto government of Alamo".[7]
Economy
By 2012 the ANSB was the only employer in Alamo.[7]
Alamo Navajo Community School is a K-12 Bureau of Indian Education-affiliated tribal school. From 1930 to 1941 a Bureau of Indian Affairs (BIA) operated a school in the community, but after that point students were boarded at distant schools. Students began attending Magdalena Municipal Schools in 1957 after the BIA opened a dormitory facility in that city. Alamo Community Navajo school opened with grades K-8 on October 1, 1979, and with high school added on December 15, 1980.[9]
