While there is no proven correlation between the quality of one's educational institution and the quality of one's professional competence, it is often an indicator. Medical schools have various levels of selectivity (some are harder to get into than others), and both the quality of their clinical training and level of research are measured. Additional medical training in both residency and fellowships and the facilities they are conducted at also provide a history of the doctors' level of training and experience.
