Value-Added Modeling (VAM) is being used increasingly as a tool in education research and accountability systems, yet little is known about the validity and reliability of the results or the potential of VAM to improve education practice. The Wisconsin Center for Education Research (WCER) organized a national conference to address some of the most important technical issues surrounding VAM as well as their implications for education policy. The research papers, conference, and related activities focused on two interrelated issues: how VAM can be used to identify effective policies and practices (school improvement) and how it can be used to identify effective teachers and schools (accountability).

The conference brought together prominent researchers from different disciplinary perspectives— sociology, economics, educational measurement, statistics, and education policy.  Although participants at the conference included some of the most technically sophisticated VAM researchers in the country, the conference was specifically designed to inform education policy. VAM will not be an acceptable tool for either school improvement or accountability if researchers disagree about how the models should be estimated. Even if there is agreement, VAM will not fulfill its promise if the estimates are not valid and reliable. The technical issues mentioned above are therefore closely interrelated with the policy issues.
