How to Raise Objections Against UPSC ISS Provisional Answer Key 2026
If a candidate disagrees with any answer published in the provisional answer key, they can submit a formal representation to UPSC within the stipulated objection window period.
UPSC allows candidates to challenge answers in the provisional answer key by submitting a formal representation. The process for raising objections is as follows:
- Download the provisional answer key PDF for the relevant paper.
- Identify the question number(s) where you believe the answer is incorrect.
- Prepare a written representation with supporting references from standard textbooks or study material.
- Submit the representation to UPSC through the official channel specified in the answer key notification (typically by post or online submission to the UPSC office).
- UPSC will review all representations received before publishing the Final Answer Key.
What Happens After the Provisional Answer Key?
After the provisional answer key is released and the objection window closes, UPSC reviews all valid representations before publishing the Final Answer Key.
Once the objection period ends, UPSC's subject matter experts review all representations submitted by candidates. Valid objections where an answer is found to be incorrect based on credible references result in changes to the final answer key. The Final Answer Key is then published on the official website. The final marks are computed based on the final (not provisional) answer key, which forms the basis for merit list preparation and eventual selection to the Indian Statistical Service.
