Background: The transition, froma student to a doctor has been described as the weakest link in the entire chain of physician training. Failure of medical schools to provide adequate clinical exposure to common medical conditions, practical procedures and communication skills has been identified as important contributing factors. The International Medical University (IMU), has attempted to improve the transition from a student to a doctor by implementing an innovative program known as the ”Senior Clerkship” in the final semester (semester 10) of its medical program. During the entire tenth semester, the students acquire knowledge, skills and attitudes by being ”shadow” houseman under the supervision of the IMU academic staff. Purpose: The purpose of this study is to evaluate the effectiveness of the senior clerkship program by assessing the house officers (HO) during their first year after graduation as this could provide a good approximation of the overall quality of the IMU undergraduate education. Methods: The clinical competence and preparedness of 493 medical graduates for their performance as house-officers in three Malaysian public hospitals was evaluated by using two sets of questionnaire developed to assess the house officers' performance by their clinical supervisors. The data was then analyzed by comparing the ratings awarded to graduates who went through the senior clerkship program versus those that did not. Results: Our results showed that the clinical supervisors rated the clinical performance of the IMU graduates to be higher than all the other medical graduates. For communication skills and attitude, IMU graduates were rated slightly lower than graduates from Australia, Ireland and the United Kingdom but higher than graduates from the rest of the universities. Conclusion: The senior clerkship program has helped to improve the transition from student to houseman.
