The Government of Canada funds elementary and secondary education for First Nations students ordinarily resident on reserve, and provides post-secondary education financial support for eligible First Nation and Inuit students. Aboriginal Affairs and Northern Development Canada (AANDC) works with First Nations and provinces/territories to support quality education for First Nations students so they can acquire the skills needed to enter the labour market and be full participants in the Canadian economy.
Despite these efforts by the government the level of illiteracy is still high among first nation people.
