Abstract: Before the 20th century, medical education in the United States was quite confusing without entrance standards, lack of quality control in the education process, and standardized license system. Flexner Report released in 1910 started the dramatic changes in medical education in America, including development of standards of entrance and length of schooling, academic accreditation of faculty in medical schools, equipping laboratories and teaching hospitals, and changing fund sources of medical schools. These reforms had greatly improved the quality of medical education, promoted the professionalization of medicine, and turned doctors into an elite profession. However, it had also resulted in some problems, such as the barrier to lower-class people to obtain formal medical services. China should learn from the reformation of medical education in the USA, solve the problems of medical education system, school system, financial support, teaching staff and curriculum system, and provide guarantee for the health of the whole people.

Key words: Professionalization of doctors, USA, Medical education reformation, Flexner Report
