[Abstract] Objective Discuss the application and effect of evaluation system in the experiment teaching of pathogenic biology and Immunology. Methods The study based on the peacetime

operating test and theory test resultof 1303 clinical medicine students of grade 2013

Calculate the normal distribution

difficulty index

distinction index and the correlation coefficient to analize the characters of the assessment model and the relationships among the compositions. Result The operation test and theoretical test show a good normal distribution

but the peacetime result show a certain negative skewness. It is a easy evaluation model that the difficulty index of the examination system is more than 0.70

In peacetime grade

the proportion of high scores accounted up to 62.09%

the distinction is only 0.10. In the evaluation system

there are significant positive correlations（r﹥0，p﹤0.01） in the peacetime

operation and the theoretical results. Conclusion The performance

operation and theoretical results according to the 3:3:4 ratio is reasonable

but some of the problems need to be improved.
