Three Universities in Thailand made it to QS University Rankings' top 100 higher-education institutions in Asia this year.

The rankings, which were released on this week, it shows Mahidol University dropping to 42nd from the 38th last year, Chulalongkorn University is retreating to 48th from 43rd and Chiang Mai University slips to 98th from the 91st. Although Thammasat did not make it in the top 100, it improved to 107th from 110th. Now in its fifth edition, QS University Rankings are providing an essential overview of higher education in one of the world's most dynamic and rapidly developing regions.

Covering the top 300 institutions in Asia, the rankings are based on nine indicators including academic reputation, employer reputation, papers per faculty and citations per paper. The top three institutions are all scoring well in the citation per paper indicator, showing that even though research productivity could be greatly improved, its impact is actually quite encouraging. Chulalongkorn University stands out for its scores in the reputational indicators, being considered highly by both academics and employers. Mahidol University is the next best Thai performer in those indicators. However, Thai universities have to keep pace with their rivals in one of the most competitive and dynamic regions in the world. Hong Kong University of Science and Technology retains the top spot it gained in 2011, a remarkable achievement for an institution that is just 22 years old.

The survey also shows a five-year surge in international students studying at ranked institutions in the region, from 175,286 in 2009 to 255,212 this year. The total international faculty has grown from 21,223 to 35,677. Asian universities have gained significant ground on their Western counterparts and could overtake them within two decades.
