The Indian Space Research Organisation (ISRO), through the ISRO Centralised Recruitment Board (ICRB), has released the provisional answer key for the UDC, Assistant, Junior Personal Assistant (JPA) and Stenographer Recruitment Examination 2026 on 25 September 2026. Candidates who appeared for the written examination on 21 September 2026 can now log in to the official ISRO portal using their mobile number and password to download their individual response sheet and the provisional answer key. The answer key is available in online PDF format. Candidates who find any discrepancy in the provisional answer key can raise objections online by paying Rs. 100 per question. The fee is refunded (minus bank charges) if the objection is found valid.
Important Note: Three things every candidate must act on immediately. First, the objection deadline has not been specified in the official notice — candidates must log in to the ISRO portal at isro.gov.in and check the active objection window before it closes. Do not assume the window is open indefinitely. Second, download both your response sheet and the provisional answer key and compare them carefully before deciding whether to raise an objection. The response sheet shows your marked answers; the answer key shows the correct answers as per ISRO. Third, every objection must be supported by valid documentary proof — subject-specific textbooks, established reference material or equivalent academic sources. Objections without supporting documents are likely to be rejected.
