This report summarizes the results of the workshop on 'Civil Society Strengthening' hosted by Save the Children in Stockholm, 29 June – 1 July 2011, an event which brought together Save the Children participants from Sweden, Norway, Denmark and the United States. The expected outputs of the workshop were to: reach a common understanding within Save the Children Sweden (SCS) on strengthening and working with civil society and partnerships in the context of Save the Children International (SCI), in order to achieve the Theory of change (based on the documented evidence of best practices from community-based programmes to advocate with government policy-makers and donors for improved policies and resources to expand benefits for those children considered the hardest to reach); provide inputs to an SCS strategy on civil society and partnership; and, outline an SCI framework for cooperation and coordination on civil society and partnership.
