Cognitive Diagnostic Assessment for Education : Theory and Applications

The purpose of this book is to identify how educational tests, especially large-scale tests given to students in grades K-12, can be improved so that they produce better information about what students know and don't know. By consulting and integrating psychological research into the design of educational tests, it is now possible to create new test items that students understand better than old test items. Moreover, these new test items help identify where students may be experiencing difficulties in learning.
