<p>Since 1988, the Board on International Comparative Studies in Education (BICSE) at the (U.S.) National Research Council of the National Academies has engaged in activities designed to increase the rigor and sophistication of international comparative studies in education by encouraging synergies between large and smaller scale international comparative education research, to identify gaps in the existing research base, and to assist in communicating results to policy makers and the public. Under the current grant (1998-2002), funded by the National Science Foundation and the U.S. Department of Education's National Center for Education Statistics, BICSE has sponsored public events and commissioned papers on the effects of the Trends in International Mathematics and Science Study (TIMSS), the power of video technology in international education research, international perspectives on teacher quality, and advances in the methodology of cross-national surveys of education achievement. This report responds to a request from the board's sponsors under the current grant to produce a report that builds on its previous work.</p>
