The QS ranking is based on surveying academic staff that declare a speciality in the subject area, and employers who recruit graduates that specialise in the discipline. It also takes into account research output and impact, with both citations and paper output measured over a five-year period.
The University also ranks 1st in the world for sports related subjects, for the sixth consecutive year.
