"A compelling critique of contemporary developments in early intervention. Beautifully written and rigorously researched this book deserves a wide audience." Brigid Featherstone, University of Huddersfield "A powerful and accessibly written analysis, this is an important critical resource for students, researchers, policy makers and practitioners who work with children and families." Janet Boddy, University of Sussex "This disturbing book forensically unpicks the relationships between science and politics. A milestone contribution to policy research." Stephen J Ball, University College London
