LSE has improved its position in the global league table of universities published by data consultants QS.
The World University Rankings published on 5 September 2011 placed LSE 64th in the table - an improvement from 80th in 2010. Cambridge was ranked as the world's best, with Harvard in second and Massachusetts Institute of Technology third.
In the UK, Cambridge was followed by Oxford and Imperial with LSE in 11th position.
The QS ranking is one of three which claim to accurately compare world universities. The other tables are produced by THE-Thomson Reuters and Shanghai Jiao Tong University .
However there is no universally agreed methodology for such a comparison and all three tables have their particular critics. LSE has long argued, and produced empirical evidence to back its claim, that its small size and exclusive focus on the social sciences result in rankings underestimating its strengths.
Robin Hoggard, Director of External Relations, said: "There is of course no flawless method for comparing widely-different universities around the world and we have produced factual arguments to show why LSE is particularly ill-served by existing rankings .
"While an improved position is always welcome, we will continue to press for tables based on better evidence and analysis than we have at present."
