This research examines the characteristics of curriculum decision making with special reference to the present national curriculum newly revised at Feb. 28, 2007. For this, qualitative data are collected from participants for decision making in the process of developing national curriculum guides. As a form to create new possibilities for summarizing the result of research, author tried to develop metaphors for similar phenomenological interpretations as an effective methodology of human understanding. Based on those metaphors the paper implies some policy measures to have better institutions of national curriculum development. First, one of major characteristics is a phenomenon of severe conflicts at the final countdown of decision making for eliciting one-set output (national curriculum guide) around various powers and cliques between subject-matters. It occurs little change even when the number of participants in the process of decision making is strikingly increased like the present revision. Second, because of difficulties to measure net values between subject matters, a value of a certain subject is measured its importance by
comparison with others. At this point, the instruction time allocation at the national time table functions as an equivalency. To cope with these predicaments, the paper suggests the devolution of authority in curriculum governance be needed for achieving not only democratizing the process of national curriculum decision making, but realizing better school curriculum.
