The Robert Wood Johnson Foundation (RWJF) has set out to expand existing partnerships and form new alliances in order to take on the most pervasive challenges of our time: improving the health and well-being of everyone in America. It has formalized its commitment by bringing together its work under the thematic efforts of "Healthy Children, Healthy Weight." As part of their learning journey, the Foundation convened "A Working Forum on Healthy Schools" on March 22-23, 2016, in Washington, D.C. Building on decades of investment and two years of intentional conversations with a wide range of stakeholders (including current and past grantees), RWJF hosted the Forum to explore systems-level efforts that could make healthy school environments the norm and not the exception in the United States. The Forum convened 75 participants from many sectors and levels--from school buildings and community organizations to federal agencies, nonprofit organizations, and the business community along with RWJF staff--to spend a day and a half listening to and learning from each other. The meeting design created a space where diverse voices could be heard and where the lived experiences of students, families, and educators could interweave with the voices of other education and health experts, policymakers, advocates, and academics. Following a foreword, this report begins with a description of the forum's objectives, the needs behind the meeting, and key themes that emerged. Section II of the report provides a summary of sessions and discussions from both days of the forum. Section III provides additional details on the overarching forum themes. The report concludes with recommendations and an afterword. Appended are: (1) Forum goals, agenda and participants; and (2) posters depicting challenges and solutions generated at community workshops. [This report was prepared by MMS Education.]
