Leiden ranking system
| Post date: 2024/12/17 |
Leiden is one of the reputable academic assessment systems that annually evaluates and ranks the world's top universities based on a complex set of valid scientometrics indicators. In this ranking system, universities are assessed according to two categories of indicators—size-dependent and size-independent—across four main criteria: scientific impact, scientific diplomacy, open access to publications, and gender diversity.
