"How do we know what’s a good school, and how do we tell schools the ways they can become better? In education there is a deep-rooted instinct to look at what is closest to hand and easiest to see. It may not be the best place to look, but it is where there are familiar questions and answers. This book takes you on a journey through the many places that matter for school success, and it shows how we can make them visible to help students learn better, teachers to teach better and schools to become more effective."

– Andreas Schleicher, Director for Education and Skills, Special Advisor to the Secretary-General, OECD Paris


With over 40 years of professional involvement in school education and assessment to the cause of achieving authentic, fair and balanced school evaluation and improvement, Peter Adams is focussed on supporting school improvement but clearly understands that schools face many challenges and must take control of the pace and direction of change. He uses a vast international evidence base to measure school performance against global best practice, so schools can see how they compare with the best, and can learn from the best.
