The powerfulness of this book, I believe, comes from its strong theoretical grounding in good quality Early Childhood research. At the same time it is very accessible to parents, teachers and caregivers working in Early Childhood. Lots of examples of children's, teachers' and parents' voices are given, clarifying and expanding on the discussion making it very readable and enjoyable. Although primarily about assessment, this book has made me reflect also on my assumptions and beliefs about children's learning. It presents a very powerful view of the role and methods of credit-based assessment in learning.
