Abstract: PURPOSE: To explore a possible method of improving prediction by analyzing the effect and influencial factors of difficulty prediction of a national board dental examinations. METHODS: The correlation between the predicted value and the measured value, and related influential factors were analyzed with SPSS 16.0 software package. RESULTS: The correlation between the predicted difficulty and the tested difficulty increased after the improvement of the method (P<0.05). The correlation was mainly reflected in the median score group of candidates. CONCLUSIONS: Improving the method of difficulty prediction can increase the prediction effect, and it is helpful to improve the forecasting ability of the test paper and to evaluate the candidates accurately.
