It is “virtually impossible to capture the quality of an entire university with all the different courses and disciplines in one figure," the university said.
Utrecht University said it did not provide any data to the makers of the British trade magazine Times Higher Education’s World University Rankings, so they couldn’t determine a score. According to Utrecht University, the rankings place “too much emphasis on scoring and competition,” while the university says it considers collaboration and openness of scientific research to be more important.
The “integrity” part is a very valid criticism. A big part of these rankings is how many papers the faculty publish per year. So you see a lot of higher ranked universities’ professors adding their names to a lot of reasearches where they didn’t really do anything except review/advise.
