UPSC Prelims 2026 Answer Key: The Union Public Service Commission (UPSC) completed the Civil Services Preliminary Examination 2026 on May 24, 2026, across various national centers. In a historic procedural shift aimed at ensuring institutional transparency, the commission is introducing a provisional answer key model starting with the 2026 cycle. This welcome update replaces the decade-long system in which answer keys were withheld until the entire recruitment cycle, including the personality tests, concluded nearly a year later.
Over eight lakh registered candidates who appeared for General Studies Paper I and Paper II (CSAT) can soon review their marks using the verified solution papers. Following the release of these official documents, an active window will open for candidates to submit representations or question objections. All submitted inputs will be reviewed by a panel of subject matter experts before the commission processes the final merit listings for the UPSC Mains examination.
