Examples are provided that show cost savings and contributions to society from extension programs in areas like teen pregnancy prevention, dropout prevention, incarceration reduction, nutrition education, and more. The document emphasizes using evaluation data to clearly communicate the public value of extension work to secure necessary support and funding.
