The purpose of this study is to explore the international literatures on private tutoring for the college entrance exam(hereafter PT) from the perspective of economics of education, which noticeably expands in South East Asia, Africa, Europe, the UK and the United States as well as Korea, and to propose a productive educational policy based on its results. According to the results of the study, the main reason for the rapid increase in PT varies between nations. In the aspect of economics of education, the worldwide growth of PT is partly due to the substitution of the quality for the quantity of children, resulting from low birth rate, which subsequently leads to the more social, economic input for each child. Last but not least, most nations attempt to be systematically involved in the restructure of the PT market in order to lower its demand, alternatively adopting the principle of laissez-faire. Some of the suggestions for policy from the other countries cases are such as demander-oriented services of the PT institutions, bechmarking of the PT institutions for management strategies and opening the information on the PT institutions to the public for making the efficient decisions on PT service choices.
