CWTS Leiden Ranking

Release Date Aviso

The 2017 edition of the Leiden Ranking will be launched on May 17th, 2017 at 11h GMT. I am happy to announce that collaboration with industry is a dimension that is included again in the 2017 edition of the ranking. The number of universities included in the ranking will increase slightly again this year.

Leiden Ranking+ analyses

Contact CWTS for a detailed benchmark analysis of your university using our sophisticated methodology for correcting for field differences. Benchmarking provides in-depth comparisons of selected universities and will provide you with valuable information to support debate and strategic decision making. Scientific activities and scientific performance in terms of impact, output and collaboration are compared.

At CWTS we are currently working hard on the preparation of the 2017 edition of our Leiden Ranking. After last year’s redesign of the Leiden Ranking website, no major changes will be made to the ranking this year. As always, we will make available the most accurate and most up-to-date bibliometric statistics on the scientific performance of major universities worldwide. Compared with last year, we expect a small increase in the number of universities included in the Leiden Ranking.
