This study examines how Hanja education policy in Korea has changed in relation to shifts in language and script policy since the twentieth century. It takes as its starting point the 1894 Royal Edict of King Kojong 高宗(r. 1863–1907), which marked the transition of Korea’s official writing system from Hanja-centered writing to Han’gŭl-centered writing. To this end, the study divides Korean language and script policy into the periods before and after 1945 and analyzes how the policies of each period affected Hanja education policy in Korea. The findings are as follows. First, the major policies that influenced Hanja education policy in Korea since the twentieth century include the 1894 Royal Edict of King Kojong, the Act on the Exclusive Use of Han’gŭl of 1948, and the Framework Act on the National Language of 2005. Second, in the process of implementing these policies, various issues related to Hanja education were discussed or put into practice, including arguments for the abolition of Hanja, Hanja education in elementary and secondary schools, Hanja education within the Korean language curriculum, the parallel notation of Hanja, the establishment of commonly used Hanja, and the designation of basic Hanja for Literary Sinitic education. Third, future Hanja education policy should be based on an investigation of Hanja vocabulary actually needed in daily life and official documents. It should also organize educational content around practical use and develop learner-customized methods that make effective use of science and technology. This study confirms that changes in language and script policy in Korea since the twentieth century have shaped the character and direction of Hanja education policy. It is expected to provide basic material for establishing Hanja education policies suited to the linguistic life ofKorean society in the future.
