This book examines the progress of institutionalisation of evaluation in European countries from various perspectives. It describes both prior developments and current states of evaluation in 16 European countries and across the European Union (EU), focussing on three dimensions, namely the political, social and professional systems. These detailed country reports, which have been written by selected researchers and authors from each of the respective countries, lead to a concluding comparison and synthesis. This is the first of four volumes of the compendium to be followed by volumes on the Americas, Africa and Australasia. The overall aim is to provide an interdisciplinary audience with cross-country learning to enable them to better understand the institutionalisation of evaluation in different nations, world regions and different sectors.
