ABSTRACT: Foundation theory and experiences are provided that support the need and value of utilizing a results-oriented approach in developing and evaluating water education programs. This approach includes the ability to determine actual learning outcomes, monitoring learning through time, and discovering attitude and behavior changes that result from program participation. The paper also includes a case study of such an evaluation project in connection with the Groundwater Foundation's annual Children's Groundwater Festival. A challenge is also made to water educators to begin assessing actual impacts of education programs on water quality. Plans for such a study relating to the Foundation's Ground-water Guardian program are outlined.
