Over the past six years, the Knowledge, Evidence and Learning for Development (K4D) Programme has been providing evidence and learning support to the Foreign, Commonwealth and Development Office, other government departments and partners. Since the programme ended in September 2022, there have been several learnings about the services K4D provided, and reflections on the impact K4D has had in the international development sector. While a previous blog explores the lessons learned, here we share some of the ways K4D has bolstered evidence-informed decision-making and organisational learning.
