ISRO Assistant UDC Final Answer Key 2026 Revised Key Out

About these answer keys

The Indian Space Research Organisation (ISRO), through the Centralised Recruitment Board (ICRB), has published the Final/Revised Response Sheets and Revised Answer Keys for the Computer Based Test (CBT) held on 21 September 2026 for the posts of Assistant, Junior Personal Assistant (JPA), Upper Division Clerk (UDC) and Stenographer, under Advertisement No. ISRO:ICRB:01(A-JPA):2026 dated 27 July 2026. The official wording on the recruitment page is "Final/Revised Response Sheets" and "REVISED ANSWER KEYS" — these are the final/revised keys after redressal of objections.

Objection stage and final stage

The Candidates Response Sheet and Objection Management Portal for the CBT held on 21 September 2026 was open from 25 September 2026 (2:00 PM) to 28 September 2026 (2:00 PM). The final/revised response sheets link is live from 27 October 2026 (1:00 PM) to 2 November 2026 (1:00 PM), for six days. ISRO states that no further objections or queries in any form will be entertained from candidates with regard to the final/revised answer key and response sheet.

What the revised keys contain

Two revised answer key PDFs are published. The Assistant/UDC revised answer key (7 pages) gives, for each question, the provisional answer key and the revised answer key — for example, question 1 changed from A to D and question 2 from D to C. The JPA/Stenographer revised answer key (2 pages) similarly gives provisional and revised keys — for example, question 1 changed from B to C, and question 2 is marked as excluded. Candidates should check the revised key for their own paper against their response sheet.

Distinct from the skill test shortlist

These answer keys are a separate document and stage from the list of candidates shortlisted for the Skill Test from the CBT, which is published zone-wise on the same recruitment page. The Skill Test is scheduled for 1 November 2026, with document verification on 31 October 2026 and on 1 November 2026 (after the Skill Test), except for the Hassan and New Delhi zones. Do not confuse the revised answer key with the shortlist.

How to check
