What have we learnt, and what are the next tasks?

So far, this book has reported an enormous amount of evidence, ours and others, on how education systems around the world can make education better for disadvantaged pupils. This has included large-scale reviews, linking and re-analysing secondary data, and in-depth primary fieldwork. This final chapter briefly summarises the key findings that appear across these various datasets and approaches and begins to consider their implications for policy and practice.
