We investigated factors related to the perception of achievement and to the degree of satisfaction of junior residents in initial clinical training. Questionnaires were given to second-year postgraduate students at 13 teaching hospitals in Japan. The response rate was 50%(n=89). The perception of achievement and the degree of satisfaction were converted to a 100-point scale. The mean±standard deviation of the two scores were 70±11 and 68±16, respectively. The average number of inpatients and whether the junior resident had taken care of patients were related to both scores. However, gender, the number of departments rotated through, and salary were not associated with either score.
