Over the past 15 years, charter schools and teachers unions have battled in state legislatures, the courts and the media. But with increasing frequency, the two groups are facing each other in the everyday operation of schools. This report summarizes the opinions expressed at a meeting of local state, and national leaders from both the charter school and teachers union communities convened to begin to answer questions such as: (1) Will on-the-ground experiences change charter schools or unions? and (2) Will existing conflicts only spread, or will direct experience lead to some moderation within each party? The meeting was held on May 20, 2006 at the Progressive Policy Institute in Washington, DC. The report makes the case that if relations are to improve, three things are needed. First, to help ground the discussion in facts, we need better evidence about the charter school teaching force and the impact of chartering on issues that matter to teachers. Second, more exemplars and models of effective union-charter partnerships can help show how important problems can be solved. Finally, both groups could engage in confidence-building measures to demonstrate their desire to make progress, not just give the appearance of openness. Appended are: (1) Participants; and (2) Agenda Questions.
