This report considers how successful London's schools have been over the past decade and identifies potentially transferable components of the success story. There is much to be learned from the transformation undergone in London that is relevant to policymakers and educationalists worldwide, working in both high-income and low-income countries. The improvement in student academic outcomes in London since 2000 has been nothing short of outstanding. This report focuses on the applicability of the lessons from London to other contexts--so that policymakers can reflect on their relevance in education systems across the globe. Our original research report into London's success sought to investigate the causal factors which underpinned the transformation of schooling in London (Baars et al., 2014). The research identified key lessons for policymakers derived directly from a mixed-methods approach combining qualitative and quantitative data. The research involved analysis of student attainment and school inspection data, a literature review and a series of expert witness interviews with key people who played a part in the London story and focus groups with teachers in London schools. This report uses the original research and data in order to address how London's story can be applied to school reform worldwide. It re-purposes the lessons in order to make them relevant to a global audience, so that policymakers in whatever context--including both the developed and developing worlds--might learn from what happened in London. This report is divided into four main chapters. An initial Overview provides a summary of the research findings. Chapter 2 outlines the statistical evidence base from 2000 to 2013 which demonstrates the scale of the improvement in academic outcomes achieved by London's government schools during this period. Chapter 3 describes the specific reforms that proved to be successful in London, while Chapter 4 identifies the underlying themes which characterised these reforms.
