Objective: To construct the competency model of excellent and common clinical medicine undergraduates according to the competency theory. Methods: Behavioral event interview was used to interview excellent clinical experts. Open questionnaire survey was conducted to clinical medical undergraduates.We compiled competency dictionary based on the above results. SPSS was used for statistical analysis

to determine the final competency dictionary. Delphi method was used to determine the final competency dictionary. According to the competency dictionary

a questionnaire survey was made to test the excellent and ordinary undergraduate students. Results: 36 features was established as final compentency model. 80 excellent clinical medical undergraduates got score of 143．65±23.53

while 100 ordinary undergraduates got score of 133．55±35.31

which indicating the competency model can distinguish excellent and ordinary clinical undergraduates. Conclusion: This competency model has theoretical and practical significance to the cultivation of clinical medical undergraduates.
