This study aims to chronologically analyse and investigate the tendency of the themes of education material developed by the Korean government for young children’s parents. For this, the content analysis was conducted and themes were drawn for 88 materials developed by government from 1981 to 2014. The results of the study are as follows. First, themes related to general parents roles were mostly in the area of parent development. This was also most evident in the themes of parent education materials as a whole. The method of supporting children’s development was the most prevalent theme in general parents roles, and the development of Korean (language) ability was the most abundant in the themes of personal development of parents. In the area of children’s development, it was physical exercise and health as the most frequently appearing theme and in the order of social and emotional development and social studies knowledge, cognitive tendency and math and science knowledge, language development and art experience and artistic creativity. As a result, problem can arise from the non-use of already developed materials and is therefore a waste of state budget. We propose closer cooperation among government departments and to reflect a substantial need for parents in developing materials for education.
