ISRO Scientist/Engineer exam on October 29: 175 posts, call letters out

The Indian Space Research Organisation's Centralised Recruitment Board (ICRB) will hold its computer-based test (CBT) for 175 Scientist/Engineer 'SC' posts on Thursday, October 29, 2026, after moving it from October 19, according to the revised schedule reported by several recruitment portals. Call letters for the test, advertised as ISRO:ICRB:03(EMC):2026, are being issued around October 22 through the ISRO website and the e-mail addresses candidates registered with. The posts are for young engineers in Electronics, Mechanical and Computer Science, and selection is through ISRO's own written test followed by an interview.

A Scientist/Engineer 'SC' post is the entry-level scientific job at ISRO, and for many engineering graduates it is one of the most sought-after first jobs in India. It offers a chance to work on satellites, launch vehicles and space missions straight out of college, with central government pay and job security. Because the board runs its own test, a candidate does not need a GATE score for this recruitment, which makes it open to final-year graduates and recent pass-outs who meet the marks requirement.

The 65% or 6.84 CGPA rule is the filter many applicants miss. ISRO's FAQs say the requirement is on the BE/BTech itself: a candidate who has also done an ME or MTech may apply only if the bachelor's degree meets the bar, and gets no extra weightage for the higher degree. That matters for students planning their next step: for ISRO, the undergraduate record carries the weight.

The change of date also has practical effects. Candidates who had booked travel for October 19 need to replan, and the extra ten days give more time to revise. The admit card, also called the call letter, is the document that gets a candidate into the exam centre; without a printed copy, entry is refused.

What to do next: download the call letter from the ISRO website using your registration details, check that your name, photograph, test city and timing are correct, and contact the recruitment board at once if anything is wrong. Read ISRO's own notice rather than relying on social media posts, since reports from third-party sites have differed on the exact release date.

Short-term: Registered candidates have until October 29 to prepare and must download and print their call letters before the test. The provisional answer key is expected within about three working days of the test, with a short window for objections, according to the recruitment schedules.

Long-term: Candidates who clear the written test go on to an interview, and those selected join ISRO centres across the country as entry-level scientists and engineers, a path that can lead to senior roles in India's space programme.

Who is affected: Engineering graduates and final-year students in Electronics, Mechanical and Computer Science who applied by September 16, 2026, their families, and coaching and college placement cells advising them.
