The University of Toronto is the 25th best university in the world and the best in Canada, according to the annual ranking of world universities done by the Centre of World Class Universities (CWCU).

The University of British Columbia was the second best in Canada and 40th overall, while McGill University and McMaster University followed at 64th and 96th.

Harvard University is the best school in the world, with Cambridge University ranked at 5th as the best non-American school.

Carleton ranked lower compared to other Canadian universities, standing at 19-20 in Canada and in the 401-500 quintile in the world ranking.

The CWCU ranks schools based on several indicators of academic or research performance.

The organization looks at the number of alumni winning Nobel Prizes and Fields Medals. The ranking also examined the number of international awards its tenured professors receive. Both categories account for 30 per cent of the final rating.

“We get a 0,” said Tyler Hall, a senior analyst at Carleton’s Institutional Research and Planning department.

The ranking also looks at the amount of researchers who have their work highly cited. According to Hall, Carleton does really well in this category.

The other indicators include the number of papers published and indexed from 2010-14. A school’s score from the indicators is then divided by the number of staff working at the institution.

“Part of it shows how the change in methodology has a huge impact on how we rank in terms of their criteria,” Hall said.

Carleton ranked in the 226-250 category in the 2015 Times Higher Education ranking, which looks more at research productivity and academic success.
