The challenges of evaluating the contribution of research to policy making are well documented. In this post Chris Roche, Alana Tomlin, Ujjwal Krishna and Will Pryor outline seven principles for effective monitoring, evaluation and learning for policy engagement. They were developed through consultation with researchers, support staff and others in a range of science and humanities disciplines at the University of Oxford and beyond. The authors suggest if research institutions want to be able to better demonstrate policy impact, they should approach monitoring and evaluation by building on the intrinsic motivation of researchers to learn and improve, rather than as an exercise in simply recording and proving impact
