This document discusses how to demonstrate the worth of extension programs to stakeholders using evaluation data. It recommends that programs 1) be research-based with clear expected outcomes, 2) accurately measure outcomes using various methods like surveys and tests, and 3) describe results in terms of public value by showing how the program benefits society. Examples are given of how to calculate public value and cost savings for programs in areas like teen pregnancy prevention, dropout prevention, incarceration reduction, nutrition education, and childhood obesity prevention. The document encourages extension agents to continue finding ways to show the value of their work.
