Cooperative State Research, Education, and Extension Service

The Cooperative State Research, Education, and Extension Service (CSREES) was an extension agency within the U.S. Department of Agriculture (USDA), part of the executive branch of the federal government. The 1994 Department Reorganization Act, passed by Congress, created CSREES by combining the former Cooperative State Research Service and the Extension Service into a single agency.

In 2009, CSREES was reorganized into the National Institute of Food and Agriculture (NIFA).
