This dataset was produced as part of the study 'Governing by Numbers: Data and Education Governance in England and Scotland', which explored the use of Quality Assurance and Evaluation (QAE) processes as a form of governance of education. In turn, this was part of a wider international project entitled 'Fabricating Quality in European Education' (FAB-Q), conducted under the auspices of the European Science Foundation EuroCores Programme. The FAB-Q study examined the way that audit, inspection, evaluation and regulation, and the growing need for data, are used to steer education at national and European level. One element comprised a survey of teachers in each national system, concerning their views of 'quality' in education, and the impact of QAE processes on teachers' work and professionalism. This dataset comprises the UK component, containing the responses to the FAB-Q survey of teachers and headteachers in England and Scotland. Further information may be found on the FAB-Q/Governing by Numbers project web page. Topics covered in the dataset include: teaching and quality in education; QAE; Quality Assurance in respondents' school; use of assessment and performance data; impact of QAE on the teaching profession; background and demographic information.
