Comprehensive Overview & Notification Background
The Indian Institutes of Science Education and Research (IISER) have officially published the IISER 2026 Round 5 Seat Allotment Result on August 24, 2026. Candidates who appeared for the IISER Aptitude Test (IAT) and registered for the centralised admission counselling can now check their seat allocation status directly on the official portal at iiseradmission.in.

Decision Making in Round 5: Freeze vs Float Options

- Freeze Option: Candidates who are fully satisfied with the seat allocated in Round 5 and do not wish to participate in subsequent rounds can select the 'Freeze' option. By selecting 'Freeze' and paying the required Seat Acceptance Fee (SAF), the candidate confirms their seat at the allocated IISER campus.
- Float Option: Candidates who accept the currently allotted seat but wish to be considered for higher preference choices in subsequent counselling rounds (if conducted) should select the 'Float' option and pay the Seat Acceptance Fee (SAF). If a higher preference seat is allotted later, the current seat is automatically vacated.
