PHOENIX (AP) _ The Obama administration has awarded $200,000 grants to each of three Indian tribes in Arizona to promote tribal operations of schools on reservations.

The grants were awarded to the Gila River Indian Community, the Tohono O’Odham Nation and the Navajo Nation.

The federal government says the grants were awarded as part of an effort to create tribally managed school systems and will be used to research and develop such school systems.
