<bold>Objectives: </bold>To respond to the 'quality assurance' of the EQ-5D-5L value set for England study.<bold>Methods: </bold>We provide a point-by-point response to the issues raised by the authors of the quality assurance paper, drawing on theoretical arguments, empirical analyses and practical considerations.<bold>Results: </bold>We provide evidence to show that many of the points made by the authors of the quality assurance are misleading, suggest misunderstandings, or are irrelevant.<bold>Conclusions: </bold>The modeling approaches which were used appropriately address the characteristics of the data and provide a reasonable representation of the average stated preferences of general public in England. We provide reflections on the conduct of stated preference studies, and suggestions for the way forward. [ABSTRACT FROM AUTHOR]
