 YSPH has a unique hybrid existence with the Yale School of Medicine, as it is both a department (established in 1915) within the School of Medicine as well as an independent, CEPH-certified school of public health (established in 1946).According to the school's website, the community benefits greatly from the Yale School of Public Health's dual roles of providing a world–class education as an accredited, fully functioning school, and by conducting cutting–edge, interdisciplinary research through its collaborative departmental partnerships at the School of Medicine and across the Yale campus.The Yale School of Public Health provides a public health education program with a low student to faculty ratio.
