I had the unique opportunity to be invited to react to the presentations of several well-known evaluators during the Stauffer Symposium on Applied Psychology, Evaluating Social Programs and Problems: Visions for the New Millennium. As I listened to the presenters I began to hear many issues that are important and relevant to evaluation. As Michael Scriven discussed the transdisciplinary view of evaluation, I began to think about how appropriate and timely this issue is in relation to program evaluation. I find that as a program evaluator, I often have to cross the boundaries of several disciplines in order to create and evaluate social service programs. These boundary leaps often entail learning about the ways in which culture is ingrained in the way human beings interact and how this interaction must be examined and addressed by competent evaluators.
