The purpose of this study is to analyze the patterns and causes of public officials political behaviors in the education policy-making process. In particular, this paper is to investigate the patterns of subjugation of administration on political power accelerated after Roh Moo-hyun government and some of those institutional and environmental factors within and outside the ministry of education affecting the way in which such patterns are emerged. The analysis of this paper shows that the reason for undermining the rationality of the recent education policy process is often from outside the educational system. In other words, most of the major educational policies were determined in an irrational way in which major participants in the policy process wielded influence over political power using superior positions, rather than through sufficient public debates with reasonable alternatives. Officials have often degenerated into a mere mechanical role in just implementing policies determined in this way. Based on this analysis, the study suggests that efforts should be made to find out more deeply about the causes of such behavior depending on the type of political behavior, and that it is important to establish an institutional mechanism to ensure proper public officials’ role based on expertise to prevent adverse effects from undue and excessive political power over the education policy-making process.
