The QS Latin American University Rankings were launched in 2011. They use academic opinion (30 percent), employer opinion (20 percent), publications per faculty member, citations per paper, academic staff with a PhD, faculty/student ratio and web visibility (10 percent each) as measures. These criteria were developed in consultation with experts in Latin America, and the web visibility data comes from Webometrics. The 2016/17 edition of the ranking ranks the top 300 universities in the region, and showed that the University of São Paulo in Brazil is the region's top institution.
