Opinion Surveys in University Rankings

In this week's Times Higher Education, Phil Baty discusses the role of reputational surveys in university ranking. It was a distinctive feature of the THE-QS rankings that they devoted 40 % of the weighting to a survey of academic opinion about the research excellence of universities. Baty points out that "The reputation survey used in the now-defunct Times Higher Education-QS World University Rankings was one of its most controversial elements: a survey of a tiny number of academics should not determine 40 per cent of a university's score".

It was not so much that a tiny number of academics was surveyed but that a tiny number responded and that this (relatively) tiny number was heavily biased towards particular countries and regions. A very obvious effect of the survey was to boost the position of Oxford and Cambridge well beyond anything they would have attained on indicators based on other more objective factors.

Whether THE can produce a better survey remains to be seen. But at least they have at last stopped calling it a peer review.
