The UCD School of Medicine (Scoil an Leighis UCD) at University College Dublin, Ireland, was founded in 1854.^[1] At undergraduate level, the school offers programmes in Medicine MB BCh BAO (undergraduate and graduate entry), BSc Biomedical Health and Life Sciences, and the BSc Radiography.^[1] At graduate level, the school UCD offers over 40 programmes for health care professionals.^[1]

The Catholic University Medical School was founded in 1854 and in 1908 it became the medical faculty of UCD.^[1] After 75 years at its original location on Cecilia Street, it moved to Earlsfort Terrace.^[4] In 2007 UCD moved again, to Belfield campus.^[4] The Health Science building sits adjacent to the Conway Institute (a biomedical and biomolecular research centre), Ireland's Centre for Research in Infectious Diseases, and the Centre for Synthesis and Chemical Biology. The UCD National Virus Reference Laboratory is also located on the Belfield campus.^[2]

The University College Dublin degree in Radiography is the oldest in Europe with the first graduates being conferred in 1994. It is the only Diagnostic Imaging Programme in the Republic of Ireland.

A pre-medicine year is completed by approximately 85% of undergraduate entry students. Thereafter, undergraduate entry medical students embark upon a three-year pre-clinical programme, followed by their final two years of clinical training in one of the affiliated teaching hospitals, either St. Vincent’s University Hospital or the Mater Misericordiae University Hospital.^[2][5][6] Graduate entry medical students study a 2-year-pre-clinical programme and study the final two years in the affiliated hospitals.^[2] Both graduate and undergraduate students complete specialist training rotations at The National Maternity Hospital, the Coombe Women & Infants University Hospital, Children's Health Ireland at Crumlin, and Children's Health Ireland at Temple Street.^[2] Upon graduation students are awarded bachelor's degrees in medicine, surgery and obstetrics.

In September 2005 there was a restructuring of the medical programme in the systems-based model, as part of a university wide implementation.

UCD has connections with several prestigious North American institutions, allowing medical students to participate in funded electives at Harvard Medical School, Washington University in St. Louis, University of Pennsylvania, University of Toronto and the University of British Columbia.^[7] The medical school also has a twinning medical programme with the RCSI & UCD Malaysia Campus.^[8]
