Presentation from Open Science: Monitoring Progress, Assessing Impact conference held 7–8 July 2025 at UNESCO Headquarters in Paris and online. Annotation: As Open Science monitoring frameworks multiply across Europe and globally, research-performing and funding organisations (RPOs and RFOs) are increasingly expected to implement, report on, and align with evolving expectations. However, the practical realities of translating policy into institutional practice remain complex. This roundtable brings together contributors from international and European initiatives to reflect on institutional uptake of Open Science monitoring and researcher assessment frameworks. Each speaker will provide a brief input grounded in their context, followed by a moderated discussion addressing barriers, synergies, and lessons learned.
