The latest World University Rankings in 2009 are published recently, and I have found that the results are quite different for the two international league tables: ARWU and THES Rankings. Both are very famous university ranking tables. In the Academic Ranking of World Universities, 8 US universities occupied the top 10 positions, with Harvard at No. 1 in the world, and Stanford at No.2, UC Bekeley ranked No.3 and Cambridge ranked No. 4, while the THES rankings 2009 have Cambridge at No. 2, Yale at No. 3 and University College London (UK) at No. 4. Yale is not even in the top 10 in ARWU ranking BUT is ranked No. 3 in THES. University College London is not in the top 10 in ARWU but it is a top 4 university according to THES. What do you think about it? Which ranking tables are more accurate?
