Where are the quantum jumps in quality assurance? Developments of a decade of research on a heavy particle

The author reviews developments in publications on quality assurance of education in (European) higher education over the last decade. The metaphor of sub-atomic structure is used to order the literature in types ('shells') of similar publications, moving from those closely related with the practice of quality assurance methods to more theoretical publications. Some seminal publications are highlighted as 'quantum jumps'. The article ends by noting some recent trends in quality assurance at the system and institutional levels, as well as mentioning theoretically interesting developments, notably the emergence of neo-institutional approaches.
