This report describes testing efforts to develop and assess a new National Crime Victimization Survey (NCVS) instrument. This testing was a part of the NCVS Instrument Redesign and Testing Project, a major multiyear effort to revamp the existing core survey instrument, which was last updated in 1992. The effort had three main goals: modernize the organization and content of the NCVS instrument, increase the quality of information collected and efficiency of the instrument flow, and improve the measurement and classification of crime. This report details the methodological design and implementation of a large-scale national field test to assess the new NCVS instrument. It also includes Appendices of draft summary reports from the NCVS instrument development and testing.
