Objective To investigate the implementation of standardized resident training in Shanghai based on the source of interns, and probe the current problems. Methods The basic information of interns for standardized resident training in Shanghai was retrospectively analysed. Results As a whole, the number of interns exhibited a continuous growth by 18.05% year by year. However, the number of interns with master degree decreased by 14.55% yearly. The interns graduated from “985” universities and “211” universities accounted for 56.7%. The number of interns with master degree and doctor degree graduated from “985” universities was significantly bigger than those from “211” universities and ordinary universities （χ²=32.679，P<0.01； χ²=11.583，P<0.05）, while the number of interns with bachelor degree graduated from ordinary universities was significantly bigger than that from “985” universities and “211” universities （χ²=14.307，P<0.01）. The vast majority (87.63%) of interns chose to practise in specialized fields, while only 12.37% took part in general practitioner training. Conclusion The number of interns for standardized resident training is insufficient, the source of interns should be improved, and the number of interns with general practitioner training should be elevated.
