In this paper, I examine the difficulty associated with the education policy from an economic point of view. At first, I comment on the "market failure" caused because of the special characteristics of the goods of "education" while being based on a standard concept of economics. From there, it is shown that public intervention by the government, that is an education policy, is necessary for education. Then, the political agreement formation pays its attention to a necessary point for the realization of the education policy practically. From there, it is clear that the incentive structure of society is likely to cause difficulties to the realization of education policy. Finally, for the realization of the education policy, I show that a framework of policymaking that interwove the concrete measures of the education policy to be required and in addition the social incentive structure is necessary, and examine the framework.
