in 1920 and in 1931 the Welsh National School of Medicine was incorporated. In 1967 the Welsh College of Advanced Technology entered the federal university as the University of Wales Institute of Science and Technology (UWIST), also in Cardiff. In 1971 St David's College (now part of the University of Wales: Trinity Saint David), Wales' oldest degree-awarding institution, suspended its own degree-awarding powers and entered the University of Wales. A financial crisis in the late eighties caused UWIST and University College Cardiff to merge in 1988, forming the University of Wales College Cardiff (UWCC). In 1992 the university lost its position as the only university in Wales when the Polytechnic of Wales became the University of Glamorgan (now part of the new University of South Wales). Re-organisation The university was composed of colleges until 1996, when the university was reorganised with a two-tier structure of member institutions in order to absorb the Cardiff Institute of Higher Education (which became the University of Wales Institute, Cardiff (UWIC), now known as Cardiff Metropolitan University) and the Gwent College of Higher Education (which became University of Wales College, Newport (UWCN)). The existing colleges became constituent institutions and the two new member institutions became university colleges. In 2003, both of these colleges became full constituent institutions and in 2004 UWCN received permission from the Privy Council to change its name to the University of Wales, Newport. Cardiff University (which had been known briefly as the University of Wales, Cardiff, between 1996 and 1999) and the University of Wales College of Medicine (UWCM) merged on 1 August 2004. The merged institution, known as Cardiff University, ceased to be a constituent institution and joined a new category of 'Affiliated/Linked Institutions'. While the new institution continued to award University of Wales degrees in medicine and related subjects, students joining Cardiff from 2005 to study other subjects were awarded Cardiff University degrees. At the same time, the university admitted four new institutions. Thus, North East Wales Institute of Higher Education (NEWI), Swansea Institute of Higher Education and Trinity College, Carmarthen (who were all previously Associated Institutions) along with the Royal Welsh College of Music & Drama (which was previously a Validated Institution) were admitted as full members of the university on 27 July 2004. The Royal Welsh College of Music & Drama subsequently left the university in January 2007. More changes followed in September 2007 when the university
