The Biennial Monitoring Report is published every two years and aggregates evidence on the performance and added value of European Partnerships. Partnerships contribute data through the Common Indicators Survey, which covers indicators aligned with the Horizon Europe lifecycle criteria, and through partnership fiches and country fiches. The report supports strategic discussions on the partnership instrument and complements internal monitoring and evaluation. Four editions are planned for 2022, 2024, 2026 and 2028, and participation in evidence gathering is mandatory for partnerships.
