Objective　To evaluate the effect of tutorial system for medical undergraduates in a non-affiliated hospital of a medical university in Jiangsu. Methods　32 senior medical undergraduates in non-affiliated hospitals were divided into two groups. The experimental group adopted tutor-guided teaching

and the control group adopted traditional teaching. Professional theoretical knowledge

clinical ability

operational ability

foreign language level

basic research ability and participation of scientific research activities of students in the two groups were evaluated. SPSS 19.0 was used for t test

chi-square test and U test. Results　The results of operational ability (t=3.537

P=0.000)

the number of papers that had been read (t=6.961

P=0.000)

quality of these (U=68.000

P=0.017)

the number of literature reviews that had been written and reading notes ( ?字2=4.747

P=0.000)

participation in scientific research activities (t=6.788

P=0.009) of students in the experimental group were better and higher than those in the control group. In the same period

there was no significant difference between the two groups in the scores of theoretical exam

clinical competence and foreign language tests. Conclusion　The implementation of tutorial system for medical students in non-affiliated hospitals is an effective measure to improve the quality of training. We should make full use of the short intership

to improve the comprehensive quality of students by establishing perfect rules

regulations and teaching evaluation system

and educate students in accordance with their own ability.
