The Japan Education Longitudinal Study (JELS) in Educational/Social Inequality Research Group co-hosted an open seminar on international and national achievement surveys with the CSD program in Ochanomizu University. There were three lectures: Achievement gap in Japanese high school students from the analyses of PISA data; Student achievement surveys in China; National Academic Achievement Survey in Japan and JELS. Each presentation reviewed existing student achievement surveys of OECD, China, and Japan in order to reflect on how to improve future JELS.（8. Jan. 2010)
