The purpose of this document is to help public authorities initiate and develop better representative deliberative processes by establishing a minimum standard for their evaluation. These guidelines provide policy makers and practitioners with an evaluation framework and methodology, as well as evaluation questionnaires.

The OECD report Innovative Citizen Participation and New Democratic Institutions: Catching the Deliberative Wave (2020) demonstrated that public authorities from all levels of government increasingly turn to Citizens' Assemblies, Citizens' Juries, and other representative deliberative processes to tackle complex policy problems. As the use of such processes increases, so does the need to determine and ultimately improve their quality. The purpose of this document is to help public authorities initiate and develop better representative deliberative processes by establishing a minimum standard for their evaluation. These guidelines provide policy makers and practitioners with an evaluation framework and methodology, as well as evaluation questionnaires.

Public authorities from all levels of government increasingly turn to Citizens' Assemblies, Juries, Panels and other representative deliberative processes to tackle complex policy problems ranging from climate change to infrastructure investment decisions. They convene groups of people representing a wide cross-section of society for at least one full day – and often much longer – to learn, deliberate, and develop collective recommendations that consider the complexities and compromises required for solving multifaceted public issues.

The OECD Guidelines for Citizen Participation Processes are intended for any public official or public institution interested in carrying out a citizen participation process. The guidelines describe ten steps for designing, planning, implementing and evaluating a citizen participation process, and discuss eight different methods for involving citizens: information and data, open meetings, public consultations, open innovation, citizen science, civic monitoring, participatory budgeting and representative deliberative processes. The guidelines are illustrated with examples as well as practical guidance built on evidence gathered by the OECD. Finally, nine guiding principles are presented to help ensure the quality of these processes.

Citizens' Assemblies (CAs) are flourishing around the world. Quite often composed of randomly selected citizens, CAs, arguably, come as a possible answer to contemporary democratic challenges. Democracies worldwide are indeed confronted with a series of disruptive phenomena such as a widespread perception of distrust and growing polarization as well as low performance. Many actors seek to reinvigorate democracy with citizen participation and deliberation. CAs are expected to have the potential to meet this twofold objective. But, despite deliberative and inclusive qualities of CAs, many questions remain open. The increasing popularity of CAs call for a holistic reflection and evaluation on their origins, current uses and future directions. The De Gruyter Handbook of Citizens' Assemblies showcases the state of the art around the study of CAs and opens novel perspectives informed by multidisciplinary research and renewed thinking about deliberative participatory processes. It discusses the latest theoretical, empirical, and methodological scientific developments on CAs and offers a unique resource for scholars, decision-makers, practitioners, and curious citizens to better understand the qualities, purposes, promises but also pitfalls of CAs.

Federal agencies have taken steps to include the public in a wide range of environmental decisions. Although some form of public participation is often required by law, agencies usually have broad discretion about the extent of that involvement. Approaches vary widely, from holding public information-gathering meetings to forming advisory groups to actively including citizens in making and implementing decisions. Proponents of public participation argue that those who must live with the outcome of an environmental decision should have some influence on it. Critics maintain that public participation slows decision making and can lower its quality by including people unfamiliar with the science involved. This book concludes that, when done correctly, public participation improves the quality of federal agencies' decisions about the environment. Well-managed public involvement also increases the legitimacy of decisions in the eyes of those affected by them, which makes it more likely that the decisions will be implemented effectively. This book recommends that agencies recognize public participation as valuable to their objectives, not just as a formality required by the law. It details principles and approaches agencies can use to successfully involve the public.

In the face of what has increasingly been referred to as an ongoing “permacrisis”, governments must cope with and respond to emerging threats while already grappling with longstanding issues such as climate change, digital disruption and low levels of trust. In this context, understanding new approaches and spreading successful ideas has never been more important.
