Editorial: Opening for debate and contestation: OECD's international early learning and child well-being study and the testing of children's learning outcomes

Abstract This special issue aims to bring critical perspectives to bear on a growing phenomenon in education: comparative assessment of educational performance using standardized measures of outcomes or ‘international large-scale assessments’. We focus on one of its latest examples: the International Early Learning and Child Well-being Study. Proposed by the Organisation for the Economic Co-operation and Development (OECD, n.d.a) in 2012, this study is now being put into practice, targeting early childhood education and young children in particular.
