Recently, emphasis has been placed on the importance of characteristic education in Korean schools. In this respect, it is not surprising that the extra-curricula activities are recommended as essential ones for the improvement of characteristic education. As is well-known, the extra-curricula activities are divided into five dimensions (club, adaptation, self-government, school event, and public service activity) according to the 7th National Curriculum. The specific purpose of this study is to analyze the current state of the club activities, as one particular kind of the extra-curricular activities, in Korean primary schools. For this, I tried to analyze the interview data which I obtained form personal interviews with ten teachers (for two of the ten teachers by e-mail interviews) from seven different primary schools. Based on the review of previous studies, I argued that spontaneity, diversity, flexibility, and autonomy should be guaranteed for the successful management of club activity in primary schools. Through an in-depth analysis, I found that the process of program designing and arrangements of students and time schedule are too rigid to fulfil the original purpose of club activity. Finally, I suggested that schools should be allowed to get flexibilities in arrangements of programs, students, and time for the success of club activities.
