World University Rankings 2018 by subject: education methodology

October 4, 2017

The Times Higher Education World University Rankings 2018 Education subject ranking includes narrower subject areas.

The list of subjects used to create this ranking is: 

  • Education
  • Teacher Training
  • Academic Studies in Education 

Different weights and measures

The subject tables employ the same range of 13 performance indicators used in the overall World University Rankings 2018, 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 Education ranking are:

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


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

For the 11 subject tables, the thresholds are set differently. For Education, the threshold drops to 100 papers published in this discipline over the past five years. And we expect an institution to have at least 1 per cent of its staff working in this discipline in order to include it in the subject table.
