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\nFollowing the release of the initial version of the rankings published on 8th June 2021, several corrections have been made (see 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\tOctober 5, 2021\r\n\t\t\t\r\n\t\t\tUniversity of California, Davis from USA moved to the position 108= after a correction of faculty and student numbers.\r\n\t\t\t\r\n\t\t\r\n\t\t\r\n\t\t\tOctober 5, 2021\r\n\t\t\t\r\n\t\t\tUniversity of Santo Tomas from Philippines changed their rank band to 801-1000 after a correction of students number. \r\n\t\t\t\r\n\t\t\r\n\t\t\r\n\t\t\tOctober 5, 2021\r\n\t\t\t\r\n\t\t\tUniversidad Rey Juan Carlos from Spain got their International Student score and rank updated after a correction, although with no change to the overall results.
