Applying qualitative methods, this paper examines the burgeoning of quality assurance databases, processes and networks of actors in the field of higher education in Europe. Our main argument is that there has been a move from the Bologna Process being the near singular focus for European-level coordination and harmonisation of higher education, towards the making of a much more diverse and complex quality assurance and evaluation infrastructure. This infrastructure involves a range of distinct but interdependent actors and processes and contains explicit and implicit interlinkages with the production of wider policy agendas, such as the rise of the European Education Area. The aim of this paper is to analyse the growth and complexity of Quality Assurance (QA) in higher education (HE) in Europe, as a way of understanding the multifaceted and continuously developing process of Europeanisation.
