Introduction In autumn 2011, the European Foundation for the Improvement of Living and Working Conditions (Eurofound) fielded the 3rd European Quality of Life Survey (EQLS) in the 27 EU Member States. During the separate phases requirements and measures for quality assurance were taken following the Terms of Reference and specific contracts. The EQLS puts a strong emphasis on quality. Hence, each stage of the study was subject to detailed documentation, and specific controls were put in place to verify compliance with the technical specifications. Important steps taken to ensure the quality of the survey and data gathered can be found throughout the whole process: in the sample stage regarding sample allocation and enumeration (e.g. geocoding and mapping); in the drafting questionnaire stage concerning questionnaire verification (e.g. pre-testing, pilot interviewing); in the translation process; during the interview process via back checking and Eurofounds’ fieldwork visits; in reporting and field follow-up via the weekly fieldwork reports and in final reporting via draft deliverables of specific reports (e.g. technical fieldwork report, coding report, translation report …) . This specific Quality Control Report was prepare
