Shortly after initial development work on the VNT, Congress transferred responsibility for VNT policies, direction, and guidelines from the department to the National Assessment Governing Board (NAGB, the governing body for the National Assessment of Educational Progress). Test development activities were to continue, but Congress prohibited pilot and field testing and operational use of the VNT pending further consideration. At the same time, Congress called on the National Research Council (NRC) to assess the VNT development activities. Since the evaluation began, the NRC has issued three reports on VNT development: an interim and final report on the first year's work and an interim report earlier on this second year's work. This final report includes the findings and recommendations from the interim report, modified by new information and analysis, and presents our overall conclusions and recommendations regarding the VNT.
