On September 4,2014, the State Council promulgated the "Implementation Opinions on Deepening the Reform of the Examination and Enrollment System" and began to comprehensively promote the reform of the education examination and enrollment system with the college entrance examination as the core. At present, a total of 14 provinces and cities are carrying out the new college entrance examination reform. The graded scoring methods of the new college entrance examination are divided into three types:the fixed grade proportional distribution system, the proportional conversion method, and the standard system. In a certain sense, the results of different elective subjects are relatively comparable and the students' excessive tendency to go overboard on one or some subjects is corrected to a degree. Nevertheless, it is difficult for all three methods to avoid the unfairness caused by the difference of group level and the distortion of scores caused by normalization of the original scores. By comparative analysis, it has been found that the degree of differentiation and the conversion accuracy of the three scoring methods are different. Therefore, it is suggested that different provinces and cities should formulate the appropriate scoring methods according to their own situations and the characteristics of the current three scoring methods.
