Rethinking Value-Added Models in Education - Amrein-Beardsley, Audrey (Mary Lou Fulton Teachers College, Arizona State University, USA)

Value-added models (VAMs) are methods meant to measure the value a teacher or school adds to student learning from one year to the next. To date, however, there is very little evidence to support their trustworthiness. The mission of this book is to shed light on this issue thereby improving states' Race-to-the-Top (RttT) reform proposals.
