To achieve national goals for education, we must measure the things that really count. Measuring What Counts establishes crucial research- based connections between standards and assessment.Arguing for a better balance between educational and measurement concerns in the development and use of mathematics assessment, this book sets forth three principlesrelated to content, learning, and equitythat can form the basis for new assessments that support emerging national standards in mathematics education.
