This article aims to clarify the possibility and the essence of the problem that the evaluation system brings by analyzing the actual situations in detail such as the enforcement methods of the school evaluation system of Jiangsu Province, China. The following three points have become clear as the result of the analysis. First, the new school evaluation system can be described as the dynamo of the whole school reform that rolled up all senior high schools in the province, where there has been already fixed rating system before. In fact, there seem to be a lot of senior high schools which rose in rank. The government intends to activate the whole system under this kind of competitive environment. In addition, the government encourages high rank senior high schools to makes ‘the education group’, so that, inside the group, they can raise low rank schools in the new system. Second, evaluation indexes and the end-points are concrete, and the direction of the effort for improving becomes plain in the new system. Accordingly, it becomes clear which direction the government is going to lead the whole senior high schools to. In high school side, it also becomes clear in what points they should change if an evaluation result is not admirable. Third, there is substantial gain for senior high schools in this star rating system, which, for instance, the four star senior high schools have the rights to select good scored students in the entrance examination process. It may lead to raise the school rank due to the good college entrance examination results that many students enroll in prestigious universities.
