Math and English are not of much value for people living a subsistence life style.  Hunting, fishing, berry picking, and food preservation, running a snow machine, sewing warm clothes, and learning how to gather wood for heat are very valued skills.  The standardized tests are irrelevant and do not measure the cognitive abilities needed for subsistence survival.  I dare anyone to create a subsistence standardized test and give it to the non Native urban students and see how well they do.  The white man has tried to assimilate the rural Alaskan Natives by imposing the White man's culture and education on them.  The Doctrine of Discovery from a papal bull issued in 1523 gave christian nations the moral authority to conquer and take land from Native tribes in the New World.  This is the foundation for White men assuming their culture is better and the cash economy is the only method of survival.  This Doctrine is used to this day by our USSC to take land from Native Americans.
