Quality Assessment of the third European Company Survey

This report presents the main results of the independent Quality Assessment of the third ECS. The assessment covers both the procedure and the output of the survey, the latter being structured according to the five output quality dimensions established in the quality framework of the ESS: relevance, accuracy (including sampling and non-sampling errors), timeliness and punctuality, accessibility and clarity, and coherence and comparability. The report completes the existing metadata of the third ECS and facilitates an appropriate understanding and application of the results of this survey. The quality assessment is based on the analysis of quality control information collected during the survey as well as primary analysis of data, paradata, metadata and dissemination products of the third ECS. The findings of this assessment support a series of recommendations on implementation strategy, methodology and management of theECS that could be applied to enhance the quality of future waves of the survey.
