Impact evaluation | Better Evaluation

An impact evaluation provides information about the impacts produced by an intervention positive and negative, intended and unintended, direct and indirect. This means that an impact evaluation must establish what has been the cause of observed changes (in this case 'impacts') referred to as causal attribution (also referred to as causal inference).
