Andreas Schleicher is Director for Education and Skills at the OECD. He initiated and oversees the Programme for International Student Assessment (PISA), and other international instruments that have created a global platform for policy-makers, researchers, and educators across nations and cultures to innovate and transform educational policies and practices. He has worked for over 20 years with ministers and education leaders to improve education. Former US Secretary of Education Arne Duncan said that Schleicher “understands the global issues and challenges as well as, or better than, anyone I’ve met, and he tells me the truth”. Former UK Secretary of State Michael Gove called Schleicher “the most important man in English education” – even though he is German and lives in France. He is the recipient of numerous honours and awards, including the “Theodor Heuss” prize, awarded in the name of the first President of the Federal Republic of Germany for “exemplary democratic engagement”. He holds an honorary Professorship at the University of Heidelberg.
