Key features

A wide range of tools and approaches to assessing social impact are classified and discussed. The section on theoretical considerations identifies a consensus around the use of theories of change; arguments for multiple methods rather than reliance on widely used metrics; the importance of avoiding the pitfall of trying to cover too much and careful selection of methodologies; and the need to focus evaluations on improving outcomes for beneficiaries.

Issues in the evaluation of social impact or development impact bonds and the monitoring and evaluation of corporate social performance/responsibility are identified. The paper concludes by identifying areas for more research, development and learning from evaluation practice.
