Indian Self-Determination and Education Assistance Act of 1975

The Indian Self-Determination and Education Assistance Act of 1975 (Public Law 93-638) authorized the secretary of the interior, the secretary of health, education, and welfare, and some other government agencies to enter into contracts with, and make grants directly to, federally recognized Indian tribes. The tribes would have authority for how they administered the funds, which gave them greater control over their welfare.
