Occasionally errors are reported after the analysis is complete and after institutions have received their rank and scores. In such cases, QS first rectifies the issue and where necessary updates the institution with a corrected set of results. If a rank change occurs we place the corrected institution in its correct position but leave all other institutions unaffected. This can result in two institutions in the same rank position with slightly different scores. In the case of an institution being removed from the rankings, again no other institutions will be affected but a gap may appear in the ranks.\r\n\r\nRankings corrections can take place either before or after publication (8th November 2023). These are referred to as pre and post release corrections. You can see the major corrections made to this edition in the table below.\r\n\r\n\r\n\t\r\n\t\t\r\n\t\t\tDate \r\n\t\t\tEdit \r\n\t\t\r\n\t\t\r\n\t\t\tPre release\r\n\t\t\tShenzhen University from China (Mainland) moved to the position 126 overall and 81 in Eastern Asia after a correction to their Staff with PhD number.
