QS Rankings Overview

The QS World University Rankings is an annual publication of university rankings by Quacquarelli Symonds (QS). Previously known as THE-QS World University Rankings, the publisher had collaborated with Times Higher Education magazine (THE) to publish its international league tables from 2004 to 2009 before both started to announce their own versions. QS then chose to still use the pre-existing methodology while THE adopted a new one.

The QS Rankings consist of a subset of rankings/ ratings which NUI Galway partake in:


For each of the above rankings and  star ratings a number of diverse metrics are used to measure and score a Universities perfomance. Two of the metrics (Academic Repuation and Employer Reputation) are based on surveys conducted by the QS. These surveys are carried out on a population of over 70,000  academics and 35,000 employers.  See more details on how the QS calculates these surveys and the other core metrics used below.
