World University Rankings 2021 by subject: law methodology

Different weights and measures

The subject tables employ the same range of 13 performance indicators used in the overall World University Rankings 2021, brought together with scores provided under five categories.

However, the overall methodology is carefully recalibrated for each subject, with the weightings changed to suit the individual fields.

The weightings for the law ranking are:

• Teaching: the learning environment
  32.7 per cent
• Research: volume, income and reputation
  30.8 per cent
• Citations: research influence
  25 per cent
• International outlook: staff, students and research
  9 per cent
• Industry income: innovation
  2.5 per cent

Criteria

Two criteria determine eligibility for the THE subject rankings: a publication threshold by discipline and an academic staff* threshold by discipline.

No institution can be included in the overall World University Rankings unless it has published a minimum of 1,000 relevant publications over the five years that we examine.

For each of the 11 subject rankings, the publication thresholds are different. For law, the threshold drops to 100 papers published in this discipline over the past five years.

There is also an academic staff eligibility criterion. Prior to the 2019 subject rankings, we expected an institution to have at least 1 per cent of its academic staff working in the law discipline in order to include it in the subject table.

Since the 2019 subject rankings, we have made a small adjustment to the staff eligibility criterion. An institution needs to have either a minimum proportion of its staff or a minimum number of staff in this discipline in order to be included in the subject ranking.

For law, we expect an institution to have either at least 1 per cent of its academic staff in the discipline or at least 20 academic staff in the discipline.

*Academic staff is defined as the full-time equivalent number of staff employed in an academic post, eg, lecturer, reader or professor.
