Editor's note:

October 2020

After the publication of the World University Rankings 2021, National Research Nuclear University MEPhI informed us that it had submitted, and signed off, incorrect academic staff, international academic staff, student and international student numbers in Life Sciences and Physical Sciences in THE’s data portal. This matter was reviewed under our corrections policy, and we agreed, at our discretion, to re-calculate MEPhI’s score based on a corrected data submission. The revision has not affected the university’s ranking position overall. The university’s corrected position in the Physical Sciences subject ranking is 98.

After the ranking production was finalised over the summer of 2020, an erroneous data point was discovered for East China Normal University. THE, in alignment with the university, decided to re-calculate East China Normal University’s score based on a corrected data submission. The university’s corrected position in the Education subject ranking is 59 and it now qualifies for the Engineering ranking. The university has also moved to a different band in the Arts and Humanities, Business and Economics, Computer Science, Life Sciences, Physical Sciences, Psychology and Social Sciences rankings. 

As per THE's rankings correction policy, where an amendment is made, the relevant institution is retrospectively listed in its correct position. We do not rerun the complete ranking. All other universities maintain their original rank.

December 2020

After the publication of the World University Rankings 2021 by subject, École Polytechnique informed us that it had submitted, and signed off, incorrect academic staff numbers for business and economics subjects in THE’s data portal, thereby excluding the institution from being ranked in the Business and Economics subject ranking, as per the inclusion criteria. This matter was reviewed under our corrections policy and we agreed, at our discretion, to calculate École Polytechnique’s score in Business and Economics based on a corrected data submission. The corrected submission means the university reached the staff threshold required to be ranked in the Business and Economics subject ranking, placing it at 97th position.

As per THE's rankings correction policy, where an amendment is made, the relevant institution is retrospectively listed in its correct position. We do not rerun the complete ranking. All other universities maintain their original rank.
