"This book is a plea from the heart, from 50+ years of experience, from someone who has immersed himself in the research, the classroom, the professional learning communities and the publication business – and Stiggins sees it all too clearly. It is time to fix the assessment problem. There is more packed into this little treatise than in encyclopedias on this topic. There is passion, wisdom, and a critical message – it is not too late but move soon. A clear blueprint is outlined as to the path to follow."
– John Hattie, Professor of Educational Research
