Abstract: Objective To establish a duty competency evaluation system in Peking Union Medical College Hospital (PUMCH) which can stratify residents based on their performance and authenticate the ability to practice medicine independently on duty. Methods Residents enrolled from PUMCH Internal Medicine Training program in 2017 and 2018 were evaluated for duty competency, the number of test and time needed to pass the test were analyzed. Results The numbers of tests needed to pass were not statistically significant(χ²=9.12,P＞0.05)in postdoctoral residents, undergraduate residents and residents from Beijing training base. Time needed to pass exam showed difference(χ²=96.27,P＜0.05) in the three resident groups. The results showed that this exam helped to stratify residents. Most residents passed exam after 6 months' internship and was competent for independ practice on duty. Conclusions In standardized training of residents, duty competency evaluation system can help to assess their capability on duty, and stratified training will help residents fulfill improvement and assure clinical safety. Residents from Beijing training base needed more clinical teaching based on their performance on the exam. Most residents passed the exam after training.

Key words: standardized training of residents, duty competency evaluation system
