High school students' comprehensive quality evaluation is a complicated job,is a kind of with a lot of uncertainty factors half structural or unstructured questions.In order to improve the existing index system reduction method and the shortcomings of the methods to determine the attribute weights,and puts forward a kind of rough set theory based on the students' quality synthetic evaluation method,this method based on the information of the attribute reduction heuristic algorithm,realize the evaluation index of the screening,so as to optimize the index system;And based on the reduction of the important degree index information to determine the weight,reduce subjective factors on the influence of the evaluation results.Through the example analysis,and verifies the feasibility and practicability of this method.
