Education value-added evaluation method based on item reaction theory IRT model

The invention discloses an education value-added evaluation method based on an item reaction theory IRT model, and the method comprises the following steps: (1) selecting a specified examination, andimporting the scores of all subjects of students; (2) converting student scores into abilities by using a project reaction theoretical model; (3) converting the ability of the students into equivalence; and (4) fitting the student ability to an education value-added evaluation model, and calculating school efficiency. According to the invention, student scores are converted into abilities by usinga project reaction theory, and the abilities of students in all groups are equivalent and placed on the same scale. Thus, a value-added evaluation mode can be used to compare the change of school efficiency of different schools, compare the change of teaching level of teachers, and calculate and compare the average efficiency of schools and teachers. 本发明公开了一种基于项目反应理论IRT模型的教育增值评价的方法，包括以下步骤：(1)选中指定的考试，导入学生各科成绩；(2)使用项目反应理论模型
