Bengaluru:  The Indian Institute of Science, Bangalore, is the world's top research university as per the citations per faculty indicator, while the Indian Institute of Technology, Guwahati, is ranked 41st in the category, according to the coveted QS World University Rankings released on Wednesday.

The Indian Institute of Science (IISc) has got a perfect score of 100 out of 100 for the citations per faculty (CPF) metric in the analysis by London-based Quacquarelli Symonds (QS).

The report that was released late on Tuesday night ranked universities on six parameters including Citations per Faculty (CPF) indicator when universities are adjusted for faculty size.

Globally, MIT has continued to retain its top slot. In the top 10, five universities are from the US including MIT which has got the first spot. The UK has as many as four universities in the top 10. Switzerland’s Swiss Federal Institute of Technology is the only non-UK or US-based institute to be featured in the top 10 of the world.

Overall, there are 22 Indian institutions in the top 1,000 list compared to 21 last year, with the Indian Institutes of Technology (IITs) in Guwahati, Kanpur, Kharagpur and Madras making major strides in rankings.

However, some institutions are still worried that the rankings do not accurately reflect the quality of education in India, as they are largely dependent on international perception factors.

IIT Bombay maintained its position as the top Indian institution for the fourth consecutive year, although it fell five places in the global rankings to the joint 177th position. IIT Delhi (185th rank) overtook the Indian Institute of Science, Bangalore (186th rank), giving India three institutions in the world’s top 100. IISc was also declared the world’s top research university by the indicator of most citations per faculty member, when adjusted for faculty size.
