多级评分可以提供更多的认知诊断信息，在对多级评分多策略实测数据进行分析的基础上提出多策略的多级评分认知诊断方法。考虑到被试使用解题策略和评分方式无关，给出一种先将多级评分转化为0-1评分，再采用0-1评分方式对策略进行诊断，最后使用多级评分诊断被试的属性掌握模式。实验结果表明了这种方法的有效性。

Polytomous models can give more information for score than dichotomous. Based on the application of the cognitive diagnosis with polytomous response,the current study developed a multiple-strategies cognitive diagnosis with polytomous response. Examinees using the problem-solving strategies and score independent are considered,the paper adopts the following methods for multiple-strategies cognitive diagnosis with polytomous response. Firstly, transform the score of polytomous to the score of dichotomous. Secondly,use the multiple-strategies cognitive diagno-sis with dichotomous response to find the problem-solving strategies of examinees. Finally,employ the multiple-strat-egies cognitive diagnosis with polytomous response to diagnose studentsˊattribute mastery patterns. Monte Carlo method was employed here to the feasibility of the multiple-strategies cognitive diagnosis with polytomous response, the results show that the method is effective and reasonable.
