Abstract: Objective To detect the evaluation effect of the integrated testing items in the National Dental Licensure Exam. Methods A portion of testing items which had been measured previously were selected randomly. The items were transformed through multidisciplinary integration and then measured again. The variation of the degree of difficulty and discrimination of the items before and after the integration were analyzed with paired ttest method for statistical analysis. Results The degree of difficulty didnt obviously change after multidisciplinary integration, but discrimination was significantly increased. This result was mainly reflected in the median score group of candidates. Conclusion Integrated items might have a better evaluation effect in the Dental Licensure Exam.
