"With the enactment of No Child Left Behind, and its sanctions for schools that fail to make adequate yearly progress, NAEP (National Assessment of Educational Progress) results are no longer afterthoughts. Instead, the results generate headlines and are at the forefront of discussion of what is working in schools and what needs to be changed. As the scrutiny of NAEP results has increased, the National Center for Education Statistics has provided more detailed reporting of the results and has increased the level of security of the assessment items. Both the level of detail and the concern for item security have played prominent roles in the development of this book."
