To evaluate the quality of microbiology final exam and improve teaching quality, two papers for un-dergraduate majoring in biological sciences in Class 2010 and 2011, department of life sciences, Liupanshui Normal University have been analysed statistically using Microsoft Excell2010? and SPSS 16.0?. The results show that the difficulty index of the papers for 2010 and 2011 classes are 0.335 and 0.346, respectively;dis-crimination index, 0.387 and 0.375;reliability index, 0.661and 0.386. Two times examination results conform to the Gaussian distribution. These data indicate that the two microbiology final exam papers may meet the examination requirements. This paper also gives some suggestions on teaching and designing exam questions for our team.
