The Harper County Cooperative Extension Office is part of the Oklahoma Cooperative Extension Service (OCES) and the Division of Agricultural Science and Natural Resources at Oklahoma State University. OCES is funded through a partnership between federal, state and county governments. The purpose of the Extension office is to provide research-based information and education so that Oklahomans may better live their lives. While traditional college and Vo-Tech instructors teach skills for employment, Extension Educators teach life-skills.

The Extension office provides education for everyone and plays a vital role in Harper County by providing practical information to help people improve their quality of life. Extension Educators provide programs on the environment, economic development, family life, health, nutrition, and youth development.

County Extension offices serve as the front door to Oklahoma State University and provide a direct link between the university and the people of the state. County educators have broad technical knowledge and often are the initial contact for many audiences served by OCES. County educators work closely with local advisory groups to plan educational programs for the county and strive to make a difference in the lives of many people by providing practical, down-to-earth information and education on a wide range of topics.

Harper County educators attempt to assess county needs, and when a need is found, prepare and deliver specific programs to the public. Extension educators also provide educational leadership for adult and youth programs, evaluate program effectiveness, and respond to client requests for specific information and technical assistance. In addition, OCES county educators coordinate and implement 4-H youth development activities, and also keep regional and state specialists apprised of community needs and issues.
