Who We Are

Our Mission

We are dedicated to a safe, sustainable, competitive food and fiber system and to strong healthy communities, families, and youth through integrated research, analysis, and education.

Local Mission

K-State Extension, Johnson County is an organization of dedicated, passionate, hardworking staff who collaborate and connect people with university supported education, resources, and services – through volunteers, community, and partner organizations.

K-State Research and Extension — Cooperative Extension Service

All universities engage in research and teaching. But the 100 land-grant colleges and universities across the country have a third critical mission — extension.

The national Cooperative Extension Service was created with the passage of the Smith-Lever Act in 1914. The service was created to assure that research-based knowledge developed by the land-grant universities got delivered to the people at the county level.

Along with research and teaching, land-grant institutions “extend” their resources through non-formal, non-credit educational programs.
