The Indian Institutes of Science Education and Research (IISER) releases the IISER 2026 Round 1 seat allotment results through its official admission portal, iiseradmission.in. Candidates who appeared for the IISER Aptitude Test (IAT) 2026 and participated in the IISER counselling process can log in to view their seat allocation and the institute/programme details assigned to them. After seat allotment in Round 1, candidates are given the option to accept the offer or wait for seat allotment in later rounds. Those who accept must complete the admission formalities, including paying the Seat Acceptance Fee (SAF), by the deadline specified in the counselling schedule. Candidates who are not allotted a seat or choose to decline their Round 1 offer may be considered in subsequent counselling rounds, subject to merit and seat availability. IISER schedules admission offer windows for later rounds following Round 1, with dates listed on the counselling timeline. The outlets advise candidates to follow the posted deadlines for seat acceptance and document submissions, as missing the time limits may lead to cancellation of the allotted seat. Candidates can download or save their admission offer letter after checking the result.
