Corruption in its many forms is a great threat to the integrity of education and research, not least because it undermines the trust placed in the educational process, devalues academic qualifications and forces the outcomes of research to be questioned. All stakeholders interested in quality and standards carry tacit responsibility for identifying, addressing and helping to eradicate corrupt practices. However, it is difficult for individuals involved in quality assurance activities to "swim against the tide" either within or externally to an institution. Strong commitment and leadership on integrity are essential prerequisites for addressing corruption and malpractice within an institution. A key complementary component in supporting integrity, together with upholding quality and standards, comes from external scrutiny, both at institutional level and for the whole HE sector, regionally or nationally. In most educational systems, this monitoring is provided by at least one designated (or sometimes selected) accreditation or quality assurance body (AQAB), usually with overarching oversight from a government department or committee. This report sets out the results from a study conducted during 2017-18 for the Council for Higher Education Accreditation / CHEA International Quality Group (CHEA/CIQG). The study was designed to capture information about actions and responses of accreditation and quality assurance bodies (AQABs) for addressing different forms of corruption in higher education. Five appendices are included in this report. [For the executive summary, see ED597948.]
