Creating “policy champions” who can bring about changes in public policy is central to many advocacy projects. But what exactly is a champion for policy change? How can we assess progress in identifying, informing, supporting, or engaging them? This brief describes our process and preliminary experiences. It also highlights challenges we have encountered. We offer these early findings in hopes that colleagues in the emerging advocacy evaluation field will take up some of these challenges and help us all better understand the role of champions in advancing social change.
