What really stunned me about this book is the way that Tom has taken the research evidence that does exist, and woven it into a powerful vision of how education can transform lives, even in the most challenging settings. I know of many books that do a great job of summarizing the research on reading, on memory, on assessment, on feedback, and so on. I do not know of a single other book that addresses so well all the threads that have to be woven together to create great schools, in such a readable way.” - Dylan Wiliam
