Policies supporting innovation and improvement in education need reliable data. There has been a long-standing effort to develop innovation indicators for the private sector that help monitor the progress of innovation and evaluate the success of associated policies. But measuring innovation and its effectiveness in the public sector, and in education in particular, is in its infancy. Despite the relative wealth of indicators in education, we still lack data that measure the innovation capacity and performance of education systems as well as link improvement to innovations in classroom and school practices. Defining and measuring innovation in education and other public services is not straight-forward. Nevertheless, there are currently a number of ongoing initiatives both within the OECD Secretariat and at national level paving the way for the development of such indicators. CERI convened a workshop in Paris on 11 June 2009 to discuss these initiatives and start a discussion on possible avenues for the international measurement of innovation in education.
