Panel at the American Evaluation Association's annual conference in Washington, D.C. October 19, 2013 by Johanna Morariu (Innovation Network), Jara Dean-Coffey (jdcPartnerships), Tom Kelly (Hawai`i Community Foundation), Claire Hutchings (Oxfam Great Britain), David Devlin-Foltz (The Aspen Institute), Robin Kane (RK Evaluation & Strategies LLC), Jared Raynor (TCC Group), and Anne Gienapp (Organizational Research Services) Advocacy and policy change evaluation continues to evolve and mature--from a fledgling field a few years ago to the flourishing field of today. Evaluators are advancing as well, developing an increasingly robust collective understanding about what works for advocacy evaluation. In this session a diverse group of seven advocacy evaluators explored and synthesized observations drawn from an array of real-world experiences. Panelists spoke to targeted questions, weaving in their wealth of experience and examples. The conversation began with this question: "What have you learned from your advocacy evaluation experience?" From there, panelists delved into the range of cases they represent. The session identified commonalities among these cases as well as contradictions/inconsistencies to move toward a field-level understanding. Presenters also used graphic recording methods to organize and report out on session themes.
