In Chile, undergraduate medical education starts after High School, it lasts seven years, with the final two dedicated to a rotary internship, taking to an M.D. degree that allows the graduate to enter working activities. The country needs more M.D.s in primary care, but there is also a shortage of specialists, mainly out of the main cities. In recent decades, post graduate programs leading to specialty titles have become competitively adopted by a large proportion of medical graduates. This is the case at the Pontificia Universidad Católica de Chile, stimulating its faculties and medical students to develop a collaborative review of their teaching programs, leading to a curricular reform with a new graduate profile and a new curriculum oriented to learning objectives, that will allow to obtain the M.D. degree in six instead of seven years of undergraduate education. This new program awakened expectations in other universities in Chile, that will have to face the attraction of this shortened program for future candidates to enter medical schools. However, any shortening of medical school careers should first consider the local conditions in quality of applicants, number of accepted students, the training of teachers in integrated teaching programs, the availability of adequate campuses. Furthermore, for students with different academic backgrounds and diverse personal and familial interests, the seven years programs may still be necessary to gain the expertise required to become medical doctors.
