Observation on the THE Ranking

There will be some comments on the latest Times Higher Education World University Rankings over the next few days.

For the moment, I would just like to point to one noticeable feature of the rankings. The scores have improved across the board.

In 2011 the top university (Caltech) had an overall score of 94.8. This year it was 95.5.

In 2011 the 50th ranked university had a score of 64.9. This year it was 69.4.

In 2011 the 100th ranked university had a score of 53.7. This year it was 57.5 for the universities jointly ranked 99th..

In 2011 the 150th ranked university had a score of 46.7. This year it was 51.6.

In 2011 the 200th ranked university had a score of 41.4. This year it was 46.2.

The overall score is a combination of 13 different indicators all of which are benchmarked against the highest scorer in each category, which receives a score of 100. Even if universities throughout the world were spending more money, improving staff - student ratios, producing more articles, generating more citations and so on, this would not in itself raise everbody's, or nearly everybody's score.

There are no methodological changes this year  that might explain what happened.
