the first University Ranking of Peru prepared by the National Assembly of Rectors of Peru under the auspices of UNESCO in 2006, in the University Rankings by Academic Performance of the URAP Center, in various editions of the QS World University Rankings by Quacquarelli Simonds, in the Web Rankings of Universities prepared by CSIC and known as Webometrics, in the University Web Rankings by 4ICU, in the University Web Rankings by 4ICU, and in the SIR World Reports by SCImago Research Center; being together with the UPCH (created by professors from the Faculty of Medicine of San Marcos) and the PUCP (whose founder and benefactor was a San Marcos graduate), one of the only three Peruvian universities that have appeared in such a position, as well as the only public one to do so.
