Editorial commentary

Impact evaluation draws methods from programme evaluation, social-science research, contribution analysis and case-study design. Approaches include counterfactual designs (where feasible), contribution analysis, theory-based evaluation, payback frameworks, and productive-interactions tracing. Funders increasingly require impact evaluation as part of grant closeout. The Research Impact Handbook, the LSE Impact Blog, and the Royal Society's impact toolkit are common reference resources.
