This paper examines a number of issues surrounding the addition of a dimension of international comparisons to the National Assessment of Educational Progress (NAEP). The basic position of the paper is that adding an international dimension to NAEP is certainly possible, but some problems will need to be overcome. Non-issues are identified and eliminated, including: (1) the organization of United States participation in the International Association for the Evaluation of Educational Achievement (IEA); and (2) response rates in IEA studies. Issues to be considered fall into three major categories: (1) financial and political, (2) technical, and (3) interpretation. Financial and political problems center around control and support for IEA projects. Another political problem relates to an IEA policy of not releasing any nation's data to another nation until an international report has been released. Technical issues include age and grade levels for testing, test construction, testing conditions, test organization, time of testing, and schedules of studies. When comparing nations, the results will need to be intepreted carefully. An appendix contains background materials about IEA. (LMO)
