In 2010 the organisations that form the E4 Group, notably ENQA (European Association for Quality Assurance in Higher Education), ESU (European Students Union), EUA (European University Association), and EURASHE (European Association of Institutions in Higher Education) launched the "Mapping the Implementation and Application of the Standards and Guidelines for Quality Assurance in the European Higher Education Area (MAP-ESG)" project in order to gather information on how the ESG have been implemented and applied in the 47 Bologna signatory countries in higher education institutions and in quality assurance institutions, and to launch a thorough discussion on the ESG in their entirety. In doing so the E4 Group responded to a discussion which has gained momentum since 2009 and which suggested that there should be a review of the ESG. This report presents the results of the activities carried out in the context of the MAP-ESG project. In doing so the report provides the first overarching study on the implementation of the ESG in all its parts, and a thorough analysis of their impact. The report is based on the analysis of expert views from all relevant actors and stakeholders in higher education, notably teachers and students, higher education management and internal quality assurance bodies, external quality assurance agencies, EQAR and ministries, and the social partners. Therefore the recommendation of the project consortium to the Bologna Follow-up Group and the Ministerial meeting in Bucharest in April 2012 is to mandate a careful revision of the ESG in order to improve their clarity, applicability and usefulness. It integrates the perspectives of all stakeholders and, thus, forms a sound basis for ministers to take a well-informed decision on the further development of the ESG. Appended are: (1) Report on the ENQA consultation; (2) Executive Summary of the ESU consultation report; (3) EUA Consultation on the Implementation of the ESG; (4) General Introduction to the EURASHE Consultation; (5) Abbreviations; and (6) Steering Group Members.
