תקציר	Summative evaluation is evaluation conducted to render an overall judgement of a program, policy or product — its merit, worth, effectiveness or impact — typically after it has been implemented or has matured. Named by Michael Scriven in his 1967 essay 'The Methodology of Evaluation' as the counterpart to formative evaluation, its purpose is to inform consequential decisions: whether to continue, expand, replicate, defund or certify an intervention. It addresses the bottom-line question 'did it work, and was it worth it?' for audiences such as funders, policymakers and the public.	Counterfactual Impact Evaluation is a family of causal methods that estimates the effect of an intervention by comparing what actually happened to participants with what would have happened had the intervention not taken place. Formalised in the Rubin Causal Model and extended by Heckman, Imbens and others, CIE underlies most modern program and policy evaluation practice.
