O uation to improve the quality of teaching from the angle of the teachers professional development. Methods　Based on the data of students' evaluation of teaching of Shanghai medical college of Fudan University from 2008 to 2011， the article analyzed the teachers' gender， age， job title， diploma， and other relevant background characteristics. Excel 2007 was used to build dataset and the data was analyzed statistically by software of SPSS 11.0 and expressed with x±s. The statistical method of one-way analysis of variance was used to compare the teachers with different genders， education backgrounds， ages and professional titles， showing statistically significant difference（P<0.05）. Results　comparative analysis showed that no statistically significant differences existed in faculty teaching evaluation scores among the teachers of different genders or different education back-grounds（P=0.613 9、0.891 0）. There were however significant differences in teaching evaluation of teachers of diverse ages and professional ranks（P=0.017 3 and P=0.032 5）. Conclusions　According to the analysis results of faculty teaching evaluations， associate professors' teaching evaluation scores were lower than intermediate grade teachers'， and the score of the teachers between the age of 41 to 45 was lower than that of the teachers between the age of 36 to 40. Therefore individual variations and various social backgrounds of teaching faculties should be taken into consideration and the corre-sponding countermeasures for the professional development of teachers should been put forward. In addition， the cultivation of new teachers， young and middle-aged teachers should be strengthened， and the proportion of teaching evaluation in the Performance Appraisal should be increased.bjective　Analyzing the impact of teachers' background characteristics on the Students' eval
