Source-derived summary

The Cooperative Extension System (CES) is a nationwide publicly-funded informal education system in the United States. CES programs are administered by land-grant universities in collaboration with federal, state, and local governments. CES was formally established by the Smith-Lever Act of 1914.

CES supports and delivers community education programs in subject areas such as agriculture, health and nutrition, family and consumer sciences, community development, natural resources, emergency preparedness, climate, volunteerism, and human sciences. CES also oversees 4-H, the largest youth development organization in the United States.

CES operates at the federal level through the National Institute of Food and Agriculture (NIFA), an agency under the United States Department of Agriculture (USDA). State-level leadership is provided by land-grant universities, and local programming is facilitated by county-level offices.

Editorial analysis

Why this record matters

“Cooperative Extension System (United States)” is worth following because a concise public description often conceals a longer documentary argument. Here, Cooperative, Extension and System provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q136534227. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1914.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
