Objective　To explore the feasibility and effectiveness of the revised OSCE stations. Methods　106 sstudents of grade 2008 and 2009 from Xinhua clinical medical school of Shanghai Jiaotong University School of Medicine were involved

32 of whom (experimental group) tool modified OSCE examination and 74 of whom (control group) tool traditional OSCE examination. The revised OSCE exam was the one which on the basis of original OSCE test station setup

improved the operating part of the test stand

adopted clinical cases as stem

asked the students to make possible diagnosis

and perform the corresponding operation. We evaluated the students based on the OSCE scores from the school exam and the overall performances in the national clinical skills competition.Comparison between the two groups was performed by using t test. Results　All students who have received the new training methods agreed that it stood closer to the clinical setting. Revised-OSCE trained group of students test scores than traditional OSCE trained group of students

though it didn't have statistical significance. Students from the revised-OSCE group had the score of (80.50±15.45)

while the tradi-tional group had the score of (78.30±17.68). By taking the revised-OSCE trainings

all the students have improved their clinical skills and two years in a row to win the Shanghai Jiaotong University School of Medicine Clinical Skills Competition. Conclusions　Case-based OSCE stations are well accepted. The new OSCE stations are much closer to clinical teaching and can make better objective assessment of students

so it plays a good role in improving medical students' overall performances.
