QS World University Rankings [SEP] History
A perceived need for an international ranking of universities for UK purposes was highlighted in December 2003 in Richard Lambert's review of university-industry collaboration in Britain for HM Treasury, the finance ministry of the United Kingdom. Amongst its recommendations were world university rankings, which Lambert said would help the UK to gauge the global standing of its universities. The idea for the rankings was credited in Ben Wildavsky's book, "The Great Brain Race: How Global Universities are Reshaping the World", to then-editor of "THE", John O'Leary. "THE" chose to partner with educational and careers advice company Quacquarelli Symonds (QS) to supply the data, appointing Martin Ince, formerly deputy editor and later a contractor to "THE", to manage the project.
