The THE World University Rankings is the definitive list of the top universities globally, including more than 1,250 institutions across 86 countries in 2019. It is the only global university league table to judge research-intensive universities across each one of their core missions: teaching (the learning environment); research (volume, income and reputation), international outlook (staff, students and research); citations (research influence); industry income (knowledge transfer). It uses 13 carefully calibrated performance indicators to provide the most comprehensive and balanced comparisons, and all data is independently audited by professional services firm PricewaterhouseCoopers (PwC), making the THE World University Rankings the only global university rankings to be subjected to full, independent scrutiny of this nature.
