ISRO SAC Scientist/Engineer Answer Key 2026

The ISRO SAC Scientist/Engineer Answer Key 2026 is an important document for candidates who appeared in the Scientist/Engineer Written Examination conducted by the Space Applications Centre (SAC), a unit of the Indian Space Research Organisation (ISRO). The written examination was conducted on 2026-07-30, and the provisional answer key is expected to be released on 2026-08-07. After its publication, candidates will be able to compare their marked responses with the officially published answers and estimate their probable scores before the declaration of the final result. The answer key will be made available through the official SAC website once the authority activates the download link. Candidates should rely only on the official portal for authentic updates regarding the answer key, response sheet, objection window, and any further announcements. Unofficial answer keys should not be considered final for score calculation or result prediction. If SAC provides a response sheet along with the provisional answer key, candidates should carefully compare every recorded response with the official answers. This comparison helps identify any discrepancies before submitting objections, if such a facility is announced. At present, the availability of the response sheet has not been officially confirmed. The objection process, if provided by SAC, will allow candidates to challenge answers they believe are incorrect. However, the authority has not yet released official details regarding the objection start date, last date, objection fee, payment mode, or document requirements. Candidates should wait for the official notification before attempting to submit any challenge. Any objection should be filed strictly within the prescribed timeline and according to the instructions issued by SAC. After reviewing all valid objections, the examination authority may publish the final answer key. The final answer key is generally used for the preparation of examination results and is considered binding. Candidates should regularly monitor the official website for updates regarding the provisional answer key, objection process, final answer key, and result declaration. Applicants are advised to keep their recruitment application details and admit card information ready before accessing the answer key portal, as login credentials may be required. They should carefully verify each question number and corresponding answer before calculating estimated marks. It is also recommended to save a copy of the answer key and any available response sheet for future reference. Candidates should avoid sharing login credentials on unofficial websites and should depend only on the official SAC portal for accurate information and updates.
