{"product_id":"science-of-evaluation","title":"Science of Evaluation","description":"Evaluation researchers are tasked with providing the evidence to guide programme building and to assess its outcomes. As such, they labour under the highest expectations - bringing independence and objectivity to policy making. They face huge challenges, given the complexity of modern interventions and the politicised backdrop to all of their investigations. They have responded with a huge portfolio of research techniques and, through their professional associations, have set up schemes to establish standards for evaluative inquiry and to accredit evaluation practitioners. A big question remains. Has this monumental effort produced a progressive, cumulative and authoritative body of knowledge that we might think of as evaluation science? This is the question addressed by Ray Pawson in this sequel to \u003ci\u003eRealistic Evaluation\u003c\/i\u003e and \u003ci\u003eEvidence-based Policy\u003c\/i\u003e. In answer, he provides a detailed blueprint for an evaluation science based on realist principles.","brand":"SAGE Publications Ltd","offers":[{"title":"Default Title","offer_id":54253220888920,"sku":"9781446252420","price":228.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781446252420.jpg?v=1777116622","url":"https:\/\/agendabookshop.com\/products\/science-of-evaluation","provider":"Agenda Bookshop","version":"1.0","type":"link"}
