08-17 TR Final Report Review of TDW.pdf

NCES provides detailed technical documentation reports that cover all aspects of the NAEP assessments. Because of the breadth and depth of the technical documentation, the development and review cycle has become quite long. Detailed technical documentation is not widely available to researchers until many years after assessment data have been collected and results have been released. This time lag results in an increased burden on NCES and contractor
staff, who must answer individual technical questions that arise, often repeatedly, before the documentation is available.
