What is school for? Drawing on his twenty years as a teacher, hundreds of interviews and his experience on the UK Government's Social Mobility Commission, head teacher Sammy Wright exposes the fundamental misconception at the heart of our education system. By focusing on the grades pupils get in neatly siloed, academic subjects, we end up ranking them and our schools into winners and losers: some pupils are set on a trajectory to university - the rest are left ill-equipped for the world they actually face. Wright's entertaining and hugely important book shows that schools are - and should be - so much more than this. With wisdom and humour, balancing idealism and pragmatism, he sets out what a better way would look like and how we might get there.
