This report written by the RRI-Tools project presents quality criteria of Good Responsible Research and Innovation (RRI) Practice Standards. It constitutes a further step in concretizing what it means to put RRI into practice. It is first and foremost meant for internal use to all partners in the RRI Tools project, as it provides a number of basic building blocks that can be used in developing or selecting (self-)evaluating, monitoring and implementation tools of which the RRI Tools toolkit will consist. Furthermore, the quality criteria may be used for thinking about how research and innovation practice should be designed to make them (more) responsible. In itself, this report on the quality criteria for good practice standards does not so much constitute a tool for implementing, monitoring or (self-)evaluating research and innovation practices on their level of responsibility. The criteria would need to be tailored to the specific context of the practice and accompanied with guidelines on how to use them. Tools could vary between areas of research and innovation, user perspectives, and purposes of the tool within research and innovation trajectories.
