What is Extension?

The Yellowstone County Extension Service is an off-campus arm of the Montana State University. Our purpose is to provide informal, unbiased, research-based information, educational resources and outreach programs to youth and adults through the Land Grant University System. This unbiased base of knowledge gives people the means to meet ever changing needs and make sound decisions that impact their lives and their communities. Agents help community members interpret the information and encourage the application of it to the solution of problems.

Extension is people-oriented and encourages widespread participation of local people, regardless of race, sex, creed, color, handicap or national origin. It is education for action, directed at helping people solve problems they encounter from day to day, and the needs of people for a better life. The problems of man, involving his community, home and children are the concern of the Extension Service.

County Agents

Education is the basic job of County Extension Agents and Assistants. As educators, they represent Montana State University and the United States Department of Agriculture. They live in the county and are in daily contact with its rural people as well as those in urban areas. They become aware of the social and economic changes that affect the lives of the local people. The County Agents provide organizational structure and programs to meet changing economic and social needs.

Subject Matter Specialists

Specialists are the link between the many sources of information (including new research), the County Agent and his/her clientele. Specialists help plan educational programs and provide informational support on the subject of their specialty. The success of the Montana Extension Service has, in large measure, been due to the dedication and high standards of performance of the men and women on the field staff.

History of the Cooperative Extension Service

The roots of Extension go deep in American history. The concept that all people can benefit from education is a great part of the tradition of free America. Founding fathers developed agricultural societies that provided educational opportunities for farmers and industrial workers. They aided in creating social, political and economic climates encouraging citizens to learn and apply their knowledge. These agricultural societies were influential in the passage of legislation permitting the establishment of Colleges of Agriculture and Mechanic Arts in all states. In 1887, Agricultural Experiment Stations were authorized and the Cooperative Extension Service was established in 1914 by the Smith-Lever Act.
