More than any previous generation, today's students need to develop a global perspective and be knowledgeable about other nations in order to play a better role on the global stage. This paper first reviews some earlier and current studies on students' knowledge of the world, mainly conducted in the United States, and then it describes the global education status and similar studies in countries like Canada, Russia, the United Kingdom, China, Japan, South Korea, and Australia. Based on a review of studies in these countries, the paper proposes that contemporary assessments of students' cross-national and global knowledge and attitudes are necessary. The new research must be multinational, assessing what paired nations' school aged populations know about one another's history, geography, politics, economics, and international relations.
