Indonesia always continually failed international assessments even though many efforts have been made. The results of PISA 2012 put Indonesian students in the worst position. In contrast, East Asian countries' performance well in mathematics, reading, and science. Indeed, Singapore has the best performance in the Southeast Asia region even in the world as well as Shanghai-China. The position of Indonesia is lower than Viet Nam, Thailand, and Malaysia in South-East Asia. Therefore, by carrying out a literature review, this paper analyzes what is happening in Indonesia beyond assessment, especially in science. Assessment reform from the above East Asian countries was also depicted to complete the discussion. Thus, this paper not only analyzed the lack of science content in Indonesia compared to other countries, but also described some lessons that can be drawn in relation to the content tested in the PISA science test from East-Asian countries.
