Restless Development has been championing the role of young people in implementation and accountability mechanisms throughout the post-2015 process. In recent months, development sector players have been sharing their proposals for the accountability architecture of the Sustainable Development Goals (SDGs). There is a lot of rhetoric around harnessing citizens’ role in formal review and accountability processes, but few practical suggestions on what this could look like on a long term and sustained basis. Restless Development has seized this moment to assess the options for the role of young people in these proposals, learning from young people’s experiences of formal and informal accountability mechanisms to date.
